Effect of dietary treatment levels on body linear measurements of growing Yankasa rams (Ovis aries) fed sorghum (Sorghum bicolor)Moench stover supplemented with graded levels of dried poultry dropping based diets was assessed using thirty growing Yankasa rams (Ovis aries) consisting of five treatments (T1-T5). Each treatment consisted of three replicates with two animals per replicate. T1: were...
Approximately 25 to 40% of the DM in premium dog diets is animal by-product. However, limited information is available regarding the composition and digestibility of these by-products, especially small intestinal digestibility. The effects of raw and rendered animal by-products incorporated into dog diets on nutrient digestion at the ileum and in the total tract were studied in this experiment....
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Phosphorus in runoff from fields where poultry litter is surface-applied is an environmental concern. We investigated the effect of adding phytase and reducing supplemental P in poultry diets and composting poultry manures, with and without Fe and Al amendments, on P in manures, composts, and runoff. We used four diets: normal (no phytase) with 0.4% supplemental P, normal + phytase, phytase + 0...

In poultry, the liver is the main organ for the synthesis of triglycerides (TG) and their secretion into the plasma. Secretion of TGs from the liver and their storage in adipose tissue of the abdominal cavity reduces the meat yield. There are controversial reports about the effects of garlic on the levels of TG in the serum and liver of poultry. In this study, different diets that contained var...
Barley consumption is limited in broiler chicken diet due to their β. glucanas polysaccharide content. The application of synthetic enzymes in poultry diet can increase the barley content. The purpose of this experiment is to study the effect of enzyme supplement-β-glucanas on the performance of broiler chickens, percentage of abdominal fat, intestine weight and economic evaluation of productio...
