phytate in poultry rations containing rice bran (rb) critically reduce poultry performance while increasing n and p excretion. the objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. twenty days old male broiler chicks (n=180) in 60 floor pens wer...

the aim of present study is investigating effect of treated lemon pulp by saccharomyces cerevisiae yeast on protein and energy metabolism in goats was fed with this product. in this experiment 8 goats from raini breed were used for 21 days period; 16 days for adaptation and 5 days for sampling, to investigate the effect of processing lemon pulp by saccharomyces cerevisiae yeast on protein recei...

objective: the aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (cgm) and its effect on growth performance of broiler chicks. methods: chemical composition and nitrogen corrected true metabolizable energy of cgm was determined by standard and precision-fed cockerel assay methods.  for evaluating of protein quality, 90 male broiler chicks in a com...

in order to study the effect of planting pattern and nitrogen application on barley and faba bean yield and quality of forage in intercropping, an experiment was conducted on farm of agricultural and natural resources faculty of gonbad kavous university as factorial based on rcbd with three replications in 2012-2013. planting pattern consisted of five levels, i.e. sole barley, intercropping of ...

effects of condensed tannins (ct) on crude protein availability in sainfoin hay was investigated according to most popular ruminant feeding systems. different treatments including polyethylene glycol (6000 mw), sodium hydroxide, sodium bicarbonate, potassium permanganate, wood ash, water and urea, were applied for deactivation of ct crude protein fractioning was determined using nylon bag techn...

in order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. treatments were the diets as follow: 1) diet for...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...

The apparent digestibility coefficients of three protein levels of reference diets (without fish meal) and test diets (with fish meal) were estimated for Labeo rohita. Three test diets (test diet-I, test diet-II and test diet-III) and three reference diets (reference diet-I, reference diet-II and reference diet-III) having 28, 30 and 32% protein levels were prepared. Chromic oxide was used as a...
