The effects of different levels of metabolizable energy and energy to protein ratios on the performance of Fars native laying hens were examined during the second laying phase. In a feeding trial, 216 Fars native hens 42 weeks old were randomly allotted to 9 experimental diets using 6 replicated groups of 4 birds per cage. The diets were formulated with 3 levels of ME (2700, 2900 and 3100 kcal/...
Background and purpose: The increased prevalence of pediatric obesity in Iran, and its associated morbidity, with its proven correlation with abdominal adiposity, is assessed by waist circumference(WC). The purpose of this study was to identify predictors of obesity among macronutrient intakes in a group of Tehranian children. Materials and Methods: 343 children aged 5-13 years (194 boys, ...
This study investigated the effects of replacing soybean meal (SM) with canola meal (CM) and decreasing crude protein (CP) levels in CM based diets on performance of dairy cows when different sources of processed grains and CM were used. Canola meal was untreated or roasted at 130°C for 30 minutes and grains sources (corn and barley) were either ground or steamed-flaked. Eight Holstein cows (...
A study was conducted to determine the effects of dietary vitamin C on growth performance, feed utilization and carcass biochemical composition of Barbus sharpeyi fingerling. Five diets containing (0, 500, 1000, 1500 and 2000 mg kg-1) of ascorbic acid were fed to benni fingerlings (6.96±0.3 g) in triplicate tanks and twice daily for a period of 56 days. The weight gain significantly increase...
This research evaluated the effects of dietary supplementation of commercial Bactocell and D-Pro probiotics on growth performance, survival and carcass composition in giant freshwater prawn Marcrobrachium rosenbergii postlarvae (PL) in a 60 day feeding trial. A total of 600 PLs with mean initial weight of 0.090± 0.004 g were assigned to five treatments each with three replicates in a completely...

this study was performed to evaluate the effects of crud protein (cp) level on dry matter intake in prepartum period, productive performance and health of fresh cows. twenty multiparous holstein cows were assigned randomly to one of two dietary treatments. dietary treatments were treatment 1, 13% cp of dm (control), and treatment 2, 16% cp of dm. diets were similar in lactation net energy and r...
Plasma renin activity varies with the level of dietary protein, being higher on a high protein diet. To explore the molecular mechanisms underlying this relationship we first examined the effect of dietary protein on renin and angiotensinogen gene expression at the level of steady state mRNA in male Sprague-Dawley rats. Renal renin mRNA was higher on a 50% (high) compared to a 6% (low) protein ...
BACKGROUND AND OBJECTIVES Epidemiologic studies show an association between higher predialysis serum phosphorus and increased death risk in maintenance hemodialysis (MHD) patients. The hypothesis that higher dietary phosphorus intake and higher phosphorus content per gram of dietary protein intake are each associated with increased mortality in MHD patients was examined. DESIGN, SETTING, PART...
The aim of this study was to investigate the effects of two dietary metabolizable protein (MP) concentrations on the performance and health status of Afshari ewes and survival and growth of their lambs during late pregnancy. For 6 weeks prior to lambing, 32 Afshari ewes were randomly assigned to two dietary treatments, containing low (LMP) or high (HMP) MP concentrations. The ewes in LMP (n=16)...
