[source] TASTE DISORDERS PRESENT IN PATIENTS WITH CHRONIC RENAL FAILURE DO NOT HAVE AN EFFECT ON OVERHYDRATION AND EXCESSIVE WEIGHT GAIN BETWEEN DIALYSES (Letter to the Editor)NEPHROLOGY, Issue 3 2005Maciej Bohatyrewicz [source] Hormone Replacement Therapy Dissociates Fat Mass and Bone Mass, and Tends to Reduce Weight Gain in Early Postmenopausal Women: A Randomized Controlled 5-Year Clinical Trial of the Danish Osteoporosis Prevention Study,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2003LB Jensen MD Abstract The aim of this study was to study the influence of hormone replacement therapy (HRT) on weight changes, body composition, and bone mass in early postmenopausal women in a partly randomized comprehensive cohort study design. A total of 2016 women ages 45,58 years from 3 months to 2 years past last menstrual bleeding were included. One thousand were randomly assigned to HRT or no HRT in an open trial, whereas the others were allocated according to their preferences. All were followed for 5 years for body weight, bone mass, and body composition measurements. Body weight increased less over the 5 years in women randomized to HRT (1.94 ± 4.86 kg) than in women randomized to no HRT (2.57 ± 4.63, p = 0.046). A similar pattern was seen in the group receiving HRT or not by their own choice. The smaller weight gain in women on HRT was almost entirely caused by a lesser gain in fat. The main determinant of the weight gain was a decline in physical fitness. Women opting for HRT had a significantly lower body weight at inclusion than the other participants, but the results in the self-selected part of the study followed the pattern found in the randomized part. The change in fat mass was the strongest predictor of bone changes in untreated women, whereas the change in lean body mass was the strongest predictor when HRT was given. Body weight increases after the menopause. The gain in weight is related to a decrease in working capacity. HRT is associated with a smaller increase in fat mass after menopause. Fat gain protects against bone loss in untreated women but not in HRT-treated women. The data suggest that women's attitudes to HRT are more positive if they have low body weight, but there is no evidence that the conclusions in this study are skewed by selection bias. [source] The Long-Term Effects of Feeding Honey Compared with Sucrose and a Sugar-Free Diet on Weight Gain, Lipid Profiles, and DEXA Measurements in RatsJOURNAL OF FOOD SCIENCE, Issue 1 2008L. Chepulis ABSTRACT:, To determine whether honey and sucrose would have differential effects on weight gain during long-term feeding, 45 2-mo-old Sprague Dawley rats were fed a powdered diet that was either sugar-free or contained 7.9% sucrose or 10% honey ad libitum for 52 wk (honey is 21% water). Weight gain was assessed every 1 to 2 wk and food intake was measured every 2 mo. At the completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. DEXA analyses were then performed to determine body composition and bone mineral densities. Overall weight gain and body fat levels were significantly higher in sucrose-fed rats and similar for those fed honey or a sugar-free diet. HbA1c levels were significantly reduced, and HDL-cholesterol significantly increased, in honey-fed compared with rats fed sucrose or a sugar free diet, but no other differences in lipid profiles were found. No differences in bone mineral density were observed between honey- and sucrose-fed rats, although it was significantly increased in honey-fed rats compared with those fed the sugar-free diet. [source] The Effect of Honey Compared to Sucrose, Mixed Sugars, and a Sugar-Free Diet on Weight Gain in Young RatsJOURNAL OF FOOD SCIENCE, Issue 3 2007L.M. Chepulis ABSTRACT:, To determine whether honey, sucrose, and mixed sugars as in honey have different effects on weight gain, 40 6-wk-old Sprague-Dawley rats were fed a powdered diet that was either sugar free or contained 8% sucrose, 8% mixed sugars as in honey, or 10% honey freely for 6 wk. Weight gain and food intake were assessed weekly, and at completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. The animals were then minced and total percentage body fat and protein measured. Overall percentage weight gain was significantly lower in honey-fed rats than those fed sucrose or mixed sugars, despite a similar food intake. Weight gains were comparable for rats fed honey and a sugar free diet although food intake was significantly higher in honey-fed rats. HbA1c and triglyceride levels were significantly higher in all sugar treatments compared with rats fed a sugar free diet, but no other differences in lipid profiles were reported. No differences in percentage body fat or protein levels were reported. [source] Effects of Brining Conditions on Weight Gain in Herring (Clupea harengus) FilletsJOURNAL OF FOOD SCIENCE, Issue 7 2005Sveinung Birkeland ABSTRACT: Salted herring is an important product category in many European countries. Reduced need for salt as a preserving agent and the increased emphasis on less salt in the human diet has changed the basis for the traditional processing of these products. This has led to significant changes in the processing conditions and in the characteristics of the salted products. In this perspective, the effects of different brine concentrations (10.0%, 16.5%, and 25.5%), brining temperatures (3.5 °C and 17.5 °C), the presence of skin or not on the fillets, and brining time (1, 2, 3, 4, and 7 d) were investigated on the weight gain (%) and final salt content (%) of herring (Clupea harengus). A significant (P < 0.001) higher weight gain of the fillets were observed at the lowest brining temperature (3.5 °C) compared with at the higher temperature (17.5 °C), independently of brine concentration and brining time. Increased brine concentration and skinning of the fillets caused the weight gain to significantly decrease (P < 0.001) and increase (P < 0.001), respectively. After 1 d of brining, the weight gain was in the range of 10% to 12% for both brining temperatures, and at the lowest temperature, the weight gain increased significantly (P < 0.001) as a function of brining time. At the higher temperature, no further significant increase in weight was observed from 1 to 7 d of brining. It is concluded that the weight gain in herring fillets brined according to the present commercial practice is significantly affected by temperature, brine concentration, brining time, and the presence or not of skin on the fillets and that the weight gain may be of high magnitude. [source] Stages of Change, Processes of Change, and Social Support for Exercise and Weight Gain in Postpartum WomenJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 2 2006Colleen Keller Objectives:, To test the extent to which social support and variables included in the Transtheoretical Model were explanatory for exercise initiation and weight maintenance in postpartum women. Design:, A cross-sectional descriptive design. Setting:, Data were collected in the participant's homes. Participants:, Postpartum women who had normal pregnancies were interviewed and measured on body fat, physical activity, and psychosocial scales. Main outcome measure:, (a) Stages of exercise change measure, (b) Seven Day Recall, (c) Friend and Family Support for Exercise Scale, (d) Processes of Change Questionnaire, and (e) body fat measures including body mass index and percent body fat. Results:, Forty percent reported engaging in vigorous activity less than 1 hour daily, 55% walked less than four city blocks daily, and 52% engaged in less than 2 hours of vigorous weekend activity. Multilinear regression showed that the processes of change contributed 36% to the body mass index, and 21% of the variance in waist-thigh ratio. Of the processes of change, environmental reevaluation correlated significantly with body mass index. Conclusion:, The impact of a woman's weight on others as well as information concerning the health effects of obesity and physical activity could enhance the initiation of exercise in the postpartum woman.

Torrent Objective:, The aim of this paper was to review the association of most commonly used psychopharmacological drugs with weight gain in bipolar disorder. Method:, Information was retrieved from a PubMed/Medline literature search reviewing weight gain in pharmacological studies in bipolar disorder. Results:, Obesity and overweight in bipolar disorder are partly related to prescribed drugs with a strong effect of clozapine and olanzapine. Lesser but still relevant weight gain is caused by quetiapine, risperidone, lithium, valproate, gabapentin and by some antidepressants. Ziprasidone, aripiprazole, carbamazepine and lamotrigine do not seem to cause significant overweight. Conclusion:, Careful monitoring of weight changes in patients before and after drug prescription should be implemented in the clinical routine and drugs which potentially cause weight gain should be avoided in overweight patients with bipolar disorder. Furthermore, eating habits and daily activities should be targeted as they may also have a significant impact on overall health and weight-related issues. [source] A reduction in severe hypoglycaemia in type 1 diabetes in a randomized crossover study of continuous intraperitoneal compared with subcutaneous insulin infusionDIABETES OBESITY & METABOLISM, Issue 11 2009A. Liebl Aim: Continuous intraperitoneal insulin infusion (CIPII) with the DiaPort system using regular insulin was compared to continuous subcutaneous insulin infusion (CSII) using insulin Lispro, to investigate the frequency of hypoglycemia, blood glucose control, quality of life, and safety. Methods: In this open, randomized, controlled, cross-over, multinational, 12-month study, 60 type 1 diabetic patients with frequent hypoglycemia and/or HbA1c > 7.0% with CSII were randomized to CIPII or CSII. The aim was to obtain the best possible blood glucose while avoiding hypoglycemia. Results: The frequency of any hypoglycemia was similar (CIPII 118.2 (SD 82.6) events / patient year, CSII 115.8 (SD 75.7) p = 0.910). The incidence of severe hypoglycemia with CSII was more than twice the one with CIPII (CIPII 34.8 events / 100 patient years, CSII 86.1, p = 0.013). HbA1c, mean blood glucose, and glucose fluctuations were not statistically different. Treatment-related severe complications occurred mainly during CIPII: port infections (0.47 events / patient year), abdominal pain (0.21 events / patient year), insulin underdelivery (0.14 events / patient year). Weight gain was greater with CSII (+ 1.5 kg vs. , 0.1 kg, p = 0.013), quality of life better with CIPII. Conclusions: In type 1 diabetes CIPII with DiaPort reduces the number of severe episodes of hypoglycemia and improves quality of life with no weight gain. Because of complications, indications for CIPII must be strictly controlled. CIPII with DiaPort is an alternative therapy when CSII is not fully successful and provides an easy method of intraperitoneal therapy. [source] Schizophrenia and weight management: a systematic review of interventions to control weightACTA PSYCHIATRICA SCANDINAVICA, Issue 5 2003G. Faulkner Objective: Weight gain is a frequent side effect of antipsychotic medication which has serious implications for a patient's health and well being. This study systematically reviews the literature on the effectiveness of interventions designed to control weight gain in schizophrenia. Method: A systematic search strategy was conducted of major databases in addition to citation searches. Study quality was rated. Results: Sixteen studies met the inclusion criteria. Five of eight pharmacological intervention studies reported small reductions in weight (<5% baseline body weight). All behavioural (including diet and/or exercise) interventions reported small reductions in, or maintenance of, weight. Conclusion: Weight loss may be difficult but it is not impossible. Given the inconsistent results, the widespread use of pharmacological interventions cannot be recommended. Both dietary and exercise counselling set within a behavioural modification programme is necessary for sustained weight control.

[source] Stability of medication in early psychosis: a comparison between second-generation and low-dose first-generation antipsychoticsEARLY INTERVENTION IN PSYCHIATRY, Issue 1 2009Stein Opjordsmoen Abstract Aim: This naturalistic study aims to compare discontinuation rates for low-dose first-generation versus second-generation antipsychotics in first-episode psychotic patients. Methods: The prescription of antipsychotic medication in 301 consecutively admitted patients with first-episode psychosis from four catchment areas is described. For the first year of inclusion a first-generation antipsychotic in low dose was recommended as the first medication. From the second year a second-generation antipsychotic was recommended as first choice. Switching was allowed when any drug was judged to be ineffective or to have serious side-effects. Switching during the first 2 years after inclusion is described. Results: Switching from a low-dose first-generation antipsychotic was more frequent than from a second-generation antipsychotic (90.7 vs. 58.4%). Lack of therapeutic effect and side-effects were the more frequently recorded reasons for changing in the first-generation group. Akathisia, parkinsonism, dyskinesias, dystonia and dysphoria were more often reported in patients on first-generation drugs. Weight gain and sedation were more often reported in patients on second-generation drugs. Conclusion: The findings suggest a better adherence to and tolerability for second-generation antipsychotics than for low-dose first-generation antipsychotics in first-episode psychosis. [source] Weight Change and Lower Body Disability in Older Mexican AmericansJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 10 2005Soham Al Snih MD Objectives: To examine the association between 2-year weight change and onset of lower body disability over time in older Mexican Americans. Design: Data were from the Hispanic Established Population for the Epidemiological Study of the Elderly (1993,2001). Weight change was examined by comparing baseline weight to weight at 2-year follow-up. Incidence of lower body disability was studied from the end of this period through an additional 5 years. Setting: Five southwestern states: Texas, New Mexico, Colorado, Arizona, and California. Participants: One thousand seven hundred thirty-seven noninstitutionalized Mexican-American men and women aged 65 and older who reported no limitation in activities of daily living (ADLs) and were able to perform the walk test at 2-year follow-up. Measurements: In-home interviews assessed sociodemographic factors, self-reported physician diagnoses of medical conditions (arthritis, diabetes mellitus, heart attack, stroke, hip fracture, and cancer), self-reported ADLs, depressive symptoms, and number of hospitalizations. Cognitive function, handgrip muscle strength, and body mass index (BMI) were obtained. The outcomes were any limitation of lower body ADL (walking across a small room, bathing, transferring from a bed to a chair, and using the toilet) and limitation on the walk test over subsequent 5-year follow-up period. General Estimation Equation (GEE) was used to estimate lower body disability over time. Results: Weight change of 5% or more occurred in 42.3% of the participants; 21.7% lost weight, 20.6% gained weight, and 57.7% had stable weight. Using GEE analysis, with stable weight as the reference, weight loss of 5% or more was associated with greater risk of any lower body ADL limitation (odds ratio (OR)=1.43, 95% confidence interval (CI)=1.06,1.95) and walking limitation (OR=1.35, 95% CI=1.03,1.76) after controlling for sociodemographic variables and BMI at baseline. Weight gain of 5% or more was associated with greater risk of any lower body ADL limitation (OR=1.39, 95% CI=1.02,1.89), after controlling for sociodemographic variables and BMI at baseline. When medical conditions, handgrip muscle strength, high depressive symptomatology, cognitive function, and hospitalization were added to the equation, the relationship between 2-year weight change (>5% loss or >5% gain) and lower body disability decreased. Conclusion: Health conditions and muscle strength partially mediate the association between weight loss or gain and future loss of ability to walk and independently perform ADLs. [source] ORIGINAL ARTICLE: Intestinal villus histological alterations in broilers fed dietary dried fermented gingerJOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 5 2010T. Incharoen Summary To evaluate the effect of dietary dried fermented ginger (DFG) on intestinal villous histological alteration and growth performance, 64 Marshall Chunky male broilers were divided into four groups, each with four replicates of four chickens. Birds were fed the basal commercial mash diet supplemented with DFG at 0 (control), 5, 10 and 20 g/kg for 42 days. With increasing dietary DFG levels, feed intake tended to decrease and significantly decreased in the 20 g/kg DFG group (p < 0.05). Weight gain was higher in all the DFG groups, with the highest in the 10 g/kg DFG group (p < 0.05), resulting in an improved feed efficiency in all the DFG groups. Intestinal villus height, villus area, cell area and cell mitosis in all the intestinal segments were higher in all the DFG groups than in the control group. Protuberated cells and cell clusters were found in all the DFG groups, suggesting that the intestinal villi and cells might be hypertrophied. The present results indicate that dietary DFG can be used as a natural feed additive to induce broiler growth performance as a result of stimulation of morphological maturation and in consequence intestinal function. [source] Evaluation of supplementary stevia (Stevia rebaudiana, bertoni) leaves and stevioside in broiler diets: effects on feed intake, nutrient metabolism, blood parameters and growth performanceJOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 6 2008J. O. Atteh Summary A perennial schrub, stevia, and its extracts are used as a natural sweetener and have been shown to possess antimicrobial properties. Stevia contains high levels of sweetening glycosides including stevioside which is thought to possess antimicrobial and antifungal properties. Little is known about the nutritional value of the schrub in livestock. This study determined the potential use of the shrub as a prebiotic animal feed supplement in light of the recent ban on the use of antibiotics in animal feed and the role of its constituent stevioside in the effects of the shrub. Male Cobb broiler chicks were fed a basal broiler diet without antibiotic but with performance enhancing enzyme mix (positive control), a basal diet without antibiotic and enzymes (negative control), or diets in which 2% of the negative control diet was replaced with either dried ground stevia leaves or 130 ppm pure stevioside during 2 week starter and 2 week grower periods. Body weight gains, feed conversion, abdominal fat deposition, plasma hormone and metabolites and caecal short chain fatty acids (SCFA) were measured in the broilers at 2 and 4 weeks of age. There was no significant effect of the treatments on feed intake during the starter period but birds fed diet supplemented with stevia leaves and stevioside consumed more feed (p < 0.05) than those fed the positive control diet during the grower period. Weight gain by birds fed the positive control and stevioside diets was higher (p < 0.05) than those fed other diets only during the starter period. Feed/gain ratio of birds fed the positive control and stevioside diets was superior (p < 0.05) to others. There was no effect of the treatments on nutrient retention and water content of the excreta. Dietary stevia leave and stevioside decreased total concentration of SCFA and changed their profile in the ceca. There was no effect of the treatments on pancreas weight. Dietary stevia reduced blood levels of glucose, triglycerides and triiodothyronine (T3) but had no effect on non-esterified fatty acids. In contrast, stevioside only decreased T3. Both the stevia leaves and stevioside diets significantly increased abdominal fat content. It is concluded that dietary enzyme growth promoters are beneficial to the broilers only during the starter stage and that inclusion of stevia leaves or stevioside has no beneficial effect on the performance of broilers.

Wen Summary The present experiment was conducted to determine the dietary vitamin A requirement of juvenile Amur sturgeon (Acipenser schrenckii) by formulating seven semipurified diets containing 10, 258, 510, 1050, 2020, 4100 and 8300 IU vitamin A (as retinol acetate) kg,1 diet, respectively. Each experimental diet was fed to triplicate groups of 20 juveniles each with initial average weights of 12.09 ± 0.22 g in 405-L aquaria and maintained at 25.0 ± 2.0°C for 8 weeks. Fish fed the basal diet (10 IU vitamin A kg,1 diet) exhibited poor appetite and activity, whereas these signs were not observed in any group fed vitamin A-supplemented diets. Weight gain, feed efficiency and hepatosomatic index increased significantly with increases in the dietary vitamin A level, reaching a peak with the vitamin A 1050 IU kg,1 diet, and then decreasing. Muscle chemical compositions were not affected by the dietary vitamin A levels. Vitamin A concentrations in liver and muscle increased significantly as the vitamin A levels increased within a range of 10,4100 IU kg,1 diet; above this level there were no significant changes. Broken-line regression analysis of weight gain and liver vitamin A concentration against the dietary vitamin A level showed that juvenile Amur sturgeon required a minimum of 923 IU vitamin A kg,1 in the diet for maximal growth, and 1981 IU kg,1 for highest liver vitamin A accumulation. [source] The Long-Term Effects of Feeding Honey Compared with Sucrose and a Sugar-Free Diet on Weight Gain, Lipid Profiles, and DEXA Measurements in RatsJOURNAL OF FOOD SCIENCE, Issue 1 2008L. Chepulis ABSTRACT:, To determine whether honey and sucrose would have differential effects on weight gain during long-term feeding, 45 2-mo-old Sprague Dawley rats were fed a powdered diet that was either sugar-free or contained 7.9% sucrose or 10% honey ad libitum for 52 wk (honey is 21% water). Weight gain was assessed every 1 to 2 wk and food intake was measured every 2 mo. At the completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. DEXA analyses were then performed to determine body composition and bone mineral densities. Overall weight gain and body fat levels were significantly higher in sucrose-fed rats and similar for those fed honey or a sugar-free diet. HbA1c levels were significantly reduced, and HDL-cholesterol significantly increased, in honey-fed compared with rats fed sucrose or a sugar free diet, but no other differences in lipid profiles were found. No differences in bone mineral density were observed between honey- and sucrose-fed rats, although it was significantly increased in honey-fed rats compared with those fed the sugar-free diet.

Chepulis ABSTRACT:, To determine whether honey, sucrose, and mixed sugars as in honey have different effects on weight gain, 40 6-wk-old Sprague-Dawley rats were fed a powdered diet that was either sugar free or contained 8% sucrose, 8% mixed sugars as in honey, or 10% honey freely for 6 wk. Weight gain and food intake were assessed weekly, and at completion of the study blood samples were removed for measurement of blood sugar (HbA1c) and a fasting lipid profile. The animals were then minced and total percentage body fat and protein measured. Overall percentage weight gain was significantly lower in honey-fed rats than those fed sucrose or mixed sugars, despite a similar food intake. Weight gains were comparable for rats fed honey and a sugar free diet although food intake was significantly higher in honey-fed rats. HbA1c and triglyceride levels were significantly higher in all sugar treatments compared with rats fed a sugar free diet, but no other differences in lipid profiles were reported. No differences in percentage body fat or protein levels were reported. [source] Supplementation of Energy-restricted Diets with Coconut Oil Improves Nitrogen Balance Without Elevation of Blood Cholesterol LevelsJOURNAL OF FOOD SCIENCE, Issue 6 2000M.Z.A. Nomani ABSTRACT: Thirty-six growing male rats were fed 1 of 6 diets for 4 wk: (1) semipurified basal diet (B) with 10% corn oil, 21.6% fat calories (FC), 14 g B diet/day; (2) B + 1 g of coconut oil (32% FC); (3) B + 1 g olive oil; (4) B + 1 g corn oil; (5) B + 2.25 g starch (18.7% FC); and (6) B + 2 g coconut oil (40% FC). Weight gain and nitrogen balance were higher (p < 0.;05) for supplemented diet groups. Serum cholesterol and triglyceride levels were not different (p > 0.05). It may be suggested that under restricted energy intake conditions (67% to 75% of the requirements) a high-fat diet (32% to 40% fat calories), including a diet rich in highly saturated coconut oil, can serve as a source of energy and contribute to improved nitrogen balance, without elevating blood cholesterol levels. [source] Milk formulas in acute gastroenteritis and malnutrition: A randomized trialJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 6 2002RH Kukuruzovic Objective: To compare three low-lactose milk formulas differing in osmolality and degree of protein hydrolysis in the treatment of diarrhoea and malnutrition in subjects with high rates of lactose intolerance, osmotic diarrhoea and a tropical/environmental enteropathy. Methods: A randomized double-blind trial of 180 Aboriginal children under 3 years of age admitted with acute diarrhoea and/or malnutrition was carried out. The intervention milk formulas were: (i) De-Lact, a low-osmolality lactose-free formula; (ii) O-Lac, a lactose-free formula; and (iii) Alfaré, a partially hydrolysed formula. Outcome measures were diarrhoeal severity, weight gain, formula palatability and changes in intestinal permeability (L/R ratios). Results: The duration of diarrhoea in days (mean; 95% confidence interval) was significantly longer on Alfaré (8.5; 7.0,10.0) compared to De-Lact (6.1; 5.0,7.2) and O-Lac (6.9; 5.6,8.1; P = 0.04). There were no differences in mean intake between formulas, but palatability of Alfaré was significantly worse (P < 0.01) than the other formulas. Over the trial 5 days, improvement in L/R ratios was significantly greater (P = 0.05) for De-Lact (18.6; 10.6,26.6) than for Alfaré (8.5; 2.1,14.9). Weight gain was not significantly different between the three formulas, except in a malnourished subgroup who had better weight gain on De-Lact (P = 0.05). Conclusions: In these Aboriginal children with diarrhoea and growth failure, a low osmolality milk was associated with better outcomes and a partially hydrolysed formula with less improvement in mucosal recovery, suggesting that cow's milk protein intolerance is not contributing to greater diarrhoeal severity or enteropathy in Aboriginal children. [source] Effect of enzymes, flavor and organic acids on nutrient digestibility, performance and carcass traits of growing,finishing pigs fed diets containing dehydrated lucerne mealJOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 1 2009Philip A Thacker Abstract BACKGROUND: We recently determined that 150 g kg,1 of lucerne meal can be fed during the finishing period without detrimental effects on pig performance but lucerne should be limited to less than 75 g kg,1 during the growing period. Lucerne has a high fiber content, is poorly digested and contains antinutritional factors such as saponins which reduce palatability. Therefore, pig performance could be enhanced by supplementing lucerne-containing diets with feed additives such as flavors, enzymes or organic acids. The objective of this study was to determine the effects of these additives on nutrient digestibility, performance and carcass traits when fed to growing-finishing swine fed diets containing lucerne. RESULTS: Flavor and enzyme had no effect on nutrient digestibility, pig performance or carcass traits. During the growing period, inclusion of propionic and acetic acids increased (P < 0.05) the digestibility of dry matter, protein and energy. Weight gain and intake also increased (P < 0.05). None of the additives had any effect on pig performance during the finishing period or on carcass traits. CONCLUSION: During the growing period, including 200 g kg,1 lucerne was detrimental to pig performance. Addition of organic acid improved pig performance and nutrient digestibility. During the finishing period, 200 g kg,1 lucerne can be successfully incorporated into pig diets without negative effects on pig performance.

We tested the effects of control diets (containing wheat products) versus diets with different Amazonian feedstuffs (yucca, Manihot sculenta, plantain, Musa paradisiaca, or pijuayo, Bactris gasipaes) on the performance of the pacus in three feeding trials. Black pacu (22.5 ± 0.03 g; Trial 1) or red pacu (2.56 ± 0.01 g; Trial 2) were fed diets containing 30% wheat bran (control) or cooked or uncooked yucca, plantain, or pijuayo for 12 wk. In Trial 3, larger black pacu (86.9 ± 6.4 g) were grown to market size in 24 wk on similar diets. Weight gain, feed conversion, survival, alternative complement activity, and lysozyme were similar among diets. Hepatosomatic index, liver glycogen, and dry matter were affected by diet in Trials 1 and 2, but effects were not consistent among trials. In Trial 3, protein efficiency ratio was lower in fish fed the diet containing wheat middlings. However, relative to wheat bran or wheat middlings, all feedstuffs tested were effective energy sources for juvenile black pacu and red pacu. [source] Effects of Dietary Vitamin A on Juvenile Red Sea Bream Chrysophrys majorJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 4 2004Luis Hector A 55-d feeding experiment was conducted to evaluate the effects of dietary vitamin A on growth of juvenile red sea bream Chrysophrys major. Nine semi-purified diets with supplemental retinol palmitate at levels of 0, 300, 600, 1,500, 3,000, 4,500, 6,000, 15,000 and 30,000 retinol eq/kg diet, were fed twice daily to triplicate groups of 10 juveniles per tank with an initial weight of 1.178 ± 0.001 g. Weight gain and specific growth rate increased with the increase of supplemental retinol palmitate in the diet up to a level of 6,000 retinol eq/kg diet, beyond which those indices tended to decrease slightly or to plateau. Significantly lower weight gain and specific growth rate were observed in fish fed with 0 and 300 retinol eq/kg diet. No significant differences were found in survival rates among the different levels of supplementation. The crude protein, lipid, moisture and ash contents in the whole body were not affected by the different vitamin A supplemental levels. Besides the reduced growth, fish fed with low levels of vitamin A supplement showed no other signs of deficiency. No hypervitaminosis A symptoms were observed in fish fed on high levels of supplementation. Fish fed on diets with 0 and 300 retinol eq/kg diet showed a significantly lower content of vitamin A (as a total retinol) in the liver than those in groups fed with higher levels of supplementation. Vitamin A was stored in the liver mainly as retinyl esters. Total retinal content of the eye showed no significant differences among the treatments; however, fish fed with 0 and 300 retinol eq/kg of diet had slightly higher concentrations. According to the results of the mean weight gain, specific growth rate and liver retinol content, the requirement of dietary vitamin A for juvenile red sea bream was estimated to be between 1,500 and 6,000 retinol eq/kg.

A feeding trial was conducted with fish meal based diets containing 10, 15, 20, 25, or 30% lipid for 24 wk. Menhaden oil was the lipid ingredient. Weight gain was significantly greater in fish fed the 30% lipid diet than in fish fed either 10%, 15% or 20% lipid diets. There were no significant differences in visceral somatic index. Fillet lipid concentration of fish fed the 30% lipid diet (9.2-g lipid/ 100-g fillet) was significantly higher (P < 0.05) than fish fed either the 10% or 15% lipid diets (5.8- and 6.9-g lipid/100-g fillet, respectively). In samples stored for 3 d at 5 C or S wk at -20 C, sensory panelists reported that the cooked fillets from fish fed the 30% lipid diet were "more fishy" than fish fed the 15% lipid diet, and preferred the cooked fillets from the 15% lipid treatment over the 30% lipid treatment. Triangle tests and fillet colorimetry showed no significant differences between fillets from fish fed the 15% and 30% lipid diets at any sampling time point. No significant differences in fillet concentrations of thiobarbituric reactive substances were observed among dietary treatments stored at either 5 C or -20 C. These results suggest that two main effects of feeding a 30% lipid diet (with fish oil as the lipid source) are a higher lipid concentration in the fillet and a "fishier" aroma compared to fillets from fish fed a 15% lipid diet. [source] Effects of Amylopectin/Amylose Starch Ratio on Growth, Body Composition and Glycemic Response of Sunshine Bass Morone chrysops × M. saxatilisJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 3 2003Steven Rawles Manipulation of the ratio of amylopectin (,-[1,4] and ,-[1,6] linked glucose) to amylose (,-[1,41 linked glucose) starches in the carbohydrate fraction of the diet has been used to improve carbohydrate and lipid metabolism in mammalian models. A 10-wk feeding trial was conducted to determine the effect of dietary amylopectin/amylose ratio on growth and composition of growth of advanced sunshine bass (Morone chrysops × M. saxatilis) fingerlings (60 g, initial weight). Fish were fed cold-pelleted, semipurified, isonitrogenous (35% crude protein), isocaloric (3.6 kcaVg protein), isolipidic (5%) diets containing 25% carbohydrate. The carbohydrate fraction of the diets was composed of either glucose, dextrin, 100% amylopectin/0% amylose, 70% amylopectin/30% amylose, or 30% amylopectin/70% amylose. Diets differing in ratios of amylopectin/amylose were achieved by adjusting the proportion of high-amylopectin (100% amylopectin) to high-amylose (70% amylose) corn starch. Diets were fed to fish in quadruplicate 76-L tanks (seven fish/tank) connected to a brackish water (5-7%v) recirculating culture system with biofiltration. Weight gain ranged from 195 to 236% of initial weight (60 g) and was significantly greater (P < 0.1) for fish fed diets containing 25% carbohydrate as dextrin or as 70% amylose and significantly lower in fish fed diets in which carbohydrate was composed of 30% amylose, 100% amylopectin, or glucose. Feed efficiency ranged from 0.52 to 0.61 and was higher in fish fed the diet containing the highest concentration of amylose and lower in fish fed the diet containing glucose. Hepatosomatic index was highest (2.71) in fish fed the diet containing glucose and lowest (1.401.45) in fish fed diets containing high-amylose cornstarch. Intraperitoneal fat ratio was distinctly lower in fish fed diets containing some amylose as compared to those fed diets without amylose. Liver lipid was significantly lower (4.8%) in fish fed the diet containing glucose and almost twice as high (7.3-8.9%) in fish fed the diets containing any starch. Glycogen content of the liver decreased from approximately 12% in fish fed the diet containing glucose to 5% in fish fed the diets containing amylose. Muscle proximate composition and ratio were unaffected by the dietary treatments. Fasting levels (15 h) of blood glucose in fish reared for 10 wk on the diet containing glucose were significantly elevated (5.5 mmol/L) when compared to fasting levels of those that had been reared on diets containing starch (3.4-1.1 mmol/L). Fish fed the diet containing glucose exhibited maximum blood concentrations (14.6 mmoVL) 4 h postprandial then rapidly declined to nearly fasting levels within 8 h postprandial. In contrast, maximum plasma glucose concentrations in fish fed diets containing starch were roughly half (6.8-8.1 mmol/L) those of fish fed the diet containing glucose. Blood glucose in fish fed diets containing dextrin or predominantly amylopectin starch remained elevated longer than that of fish fed diets containing glucose or predominantly amylose starch. Glycemic response appeared to decrease with increasing dietary amylose content. These data suggest that feeding diets in which a greater portion of the starch is amylose may be a useful strategy for improving carbohydrate use in sunshine bass. [source] Dietary Lipid Utilization by Juvenile Summer Flounder Paralichthys dentatusJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 2 2003T. Gibson Gaylord The ability of juvenile summer flounder Paralichthys dentatus to utilize dietary lipid as energy, and the effect of dietary lipid on weight gain and body composition was investigated in a 12-week feeding trial. Diets were formulated to provide 55% crude protein from herring meal and casein. Menhaden oil was added to produce diets with 8, 12, 16 or 20% total lipid while providing 16.0 kJ available energy/g dry diet. The diet containing 20% total lipid supplied 16.7 kJ available energy/g dry diet due to the high levels of protein and lipid. An additional diet was included to reproduce currently available commercial diet formulations for flounder, providing 55% crude protein supplied solely from herring meal and 16% total dietary lipid. Juvenile summer flounder (initial weight 23 g) were stocked into triplicate aquaria in a closed, recirculating system maintained at 20 C. Fish were fed 2% of body weight each day divided into two equal feedings. Upon termination of the study, effects of dietary lipid on weight gain, body condition indices, and proximate composition were determined. Weight gain (96,149% of initial weight), feed efficiency ratio values (0.43,0.48). fillet yield, and whole-body composition all were unaffected by dietary lipid level. High levels of dietary lipid did increase the lipid content in the finray muscle, as fish fed diets containing 16 and 20% dietary lipid had significantly higher lipid levels than fish fed the diet containing 8% lipid. No apparent protein sparing effect of lipid was observed. These data indicate that currently available commercial feeds for summer flounder may be over-formulated and show a need for further research to determine specific and accurate nutritional information for this species. [source] Evaluation of Experimental and Practical Diets for Walleye Stizostedion vitreumJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 3 2002Anant S. Bharadwaj Culture of walleye Sfizostedion vitreum is one of the largest components of public sector aquaculture in the eastern U.S. and there is increasing interest in private sector culture. However, the nutritional requirements of walleye are unknown and experimental diets for use in quantifying nutritional requirements have not been identified. We formulated four experimental and four practical diets and fed those to triplicate groups of walleye with an initial weight of 13 g per fish. The experimental diets contained either casein (CAS), casein + gelatin (CG), casein + arginine (CA), or casein + gelatin + crystalline amino acids (CGAA) as sources of amino acids. The practical diets were formulated to mimic salmon grower (SG) and trout grower (TG) diets, a fish meal-free diet for trout (TFMF), and a walleye grower (WG) diet. Fish were fed twice daily to satiation for 9 wk. Feed consumption, percent weight gain, specific growth rates, feed efficiency, protein efficiency ratio, and protein retention efficiency were not significantly different among fish fed CGAA, SG, and TG, but those values were significantly higher than in fish fed other diets. Weight gain of fish fed CGAA was approximately 80% of that in fish fed SG and 91% of that in fish fed TG. Protein retention efficiency of fish fed CGAA was approximately 69% and 81% of that observed for fish fed SG, and TG, respectively. In general, the carcasses of fish fed diets CGAA, SG and TG had significantly lower moisture and ash concentrations, and higher lipid levels than fish fed other diets. There were no significant differences in carcass protein concentration, muscle proximate composition, or liver lipid concentration among treatments. Livers from fish fed all diets were characterized by microvesicular degeneration and glycogen accumulation in hepatocytes. Results from the study indicate that CGAA can be used as a basal experimental diet in future nutritional research with juvenile walleye and confirms the benefits of trout and salmon grower diets. Fish meal-free diets formulated around the requirements for rainbow trout were consumed at approximately 80% of the values in fish fed TG and SG, but weight gain was approximately 20% of that in fish fed TG and SG. It appears the nutritional requirements for walleye are different than those of rainbow trout. [source] Effects of Dietary Protein and Energy Levels on Growth and Body Composition of Juvenile Flounder Paralichthys olivaceusJOURNAL OF THE WORLD AQUACULTURE SOCIETY, Issue 3 2000Sang-Min Lee A feeding trial of three protein levels (30, 40 and 50%) and two energy levels (300 and 400 kcal/100-g diet) factorial design with three replications was carried out to investigate the proper dietary protein and energy levels for the growth of juvenile flounder Paralichthys olivaceus. Weight gain of fish tended to improve with increasing dietary protein level. Weight gain of fish fed either the 40% or 50% protein diet with 300 kcal/100-g diet was significantly higher (P < 0.05) than with 400 kcal/100-g diet. The best weight gain was obtained from fish fed the 50% protein diet with 300 kcal/100-g diet. Feed efficiency tended to improve with increasing dietary protein level. However, dietary energy level had no significant effect on feed efficiency of fish fed the 30% or 50% protein diet, but that of fish fed the 40% protein diet with 300 kcal/100-g diet was significantly higher than with 400 kcal/100-g diet. Protein retention tended to increase as dietary protein level increased and energy level decreased. Lipid content of fish fed the diet containing 400 kcal/100-g diet was significantly higher than that of fish fed the diet containing 300 kcal/100-g diet at all protein levels. Fatty acid compositions such as linoleic acid, EPA (20:5n-3) and DHA (22:6n-3) offish were directly affected by dietary lipid (squid liver oil and/or soybean oil) used for energy source. Based on the above results, it can be concluded that the proper dietary protein and energy levels for the growth of juvenile flounder are 50% and 300 kcal/100-g diet, respectively. [source] Weight and weight gain at 4 months (The Netherlands 1998): influences of nutritional practices, socio-economic and ethnic factorsPAEDIATRIC & PERINATAL EPIDEMIOLOGY, Issue 4 2002Anneke M. W. Bulk-Bunschoten Summary We describe the determinants of weight gain in the first 4 months of life in a cohort of 3256 infants. The study was designed as a survey with follow-up. In the period 1 April to 1 July 1998, all infants, usually 4 weeks old but not older than 4 months, brought to a well-baby clinic for the first time were included. Nutritional practices, demographic data on mother and child, birthweight and a second weight measured between days 118 and 147 were recorded. Simple and multiple linear regression analyses were performed. The average weight gain over 4 months was 27.7 g/day for boys and 24.5 g/day for girls. Weight gain was lower with high parity and if the mother was a native Dutch speaker. Nutritional practices affected weight gain only slightly: exclusive breast feeding for 4 months lowered the weight gain by 0.06 g/day. However, because of their higher birthweight, breast-fed infants weighed a little more than formula-fed infants at 4 months. In addition, we compared the median weight at the age of 4 months with the median weight at the same age in previous Dutch growth studies. The median weight, adjusted to day 133, was higher in 1998 than in 1965, 1980 and 1997 (boys 7.15 vs. 6.85, 6.77 and 6.95 kg; girls 6.59 vs. 6.49, 6.39 and 6.45 kg respectively). [source] Acute weight gain and diastolic dysfunction as a potent risk complex for post stem cell transplant atrial fibrillation,AMERICAN JOURNAL OF HEMATOLOGY, Issue 8 2009Kaniz Fatema The management of atrial fibrillation (AF) following stem cell transplant (SCTX) is often challenging because of the universal presence of profound bone marrow suppression. The incidence of and risk factors for AF/flutter following SCTX are not well known. A total of 395 multiple myeloma (MM) patients consecutively underwent SCTX between 2002 and 2005 at the Mayo Clinic, and 383 of whom, mean age 57 ± 9 years, had no history of evidence of AF/flutter constituted the study population. During 1,002 person-years of follow up, 39 (10%) patients developed first AF/flutter (incidence of 39 per 1,000 person years), and 28 of these (72%) occurred within 21 days of SCTX. In multivariable-adjusted analyses, weight gain of ,7% in the 1st week post-SCTX (HR 3.68; P = 0.0120) and presence of diastolic dysfunction at MM diagnosis (HR 2.294; P = 0.0082) were independent predictors of AF/flutter. The risk of AF/flutter post-SCTX increased by about ninefold when both factors were present. Compared to age and sex-matched MM patients without SCTX, the risk of AF/flutter differed significantly only over the 1st year after MM diagnosis, during which SCTX was performed for the majority. Beyond the 1st year, there was no significant difference in risk of AF/flutter between the two groups. The data suggested that SCTX was associated with significantly increased risk of first AF/flutter, which typically occurred within the first 21 days of the transplant. Weight gain of ,7% was strongly predictive of first AF/flutter, and the risk was augmented by the presence of diastolic dysfunction at baseline. Am. J. Hematol. 2009. © 2009 Wiley-Liss, Inc.
