an experiment was conducted to evaluate the effects of dietary crude protein (cp) and lysine levels on performance and nitrogen excretion in broiler chickens. four hundred twenty 7-day old chickens from ross 308 strain were randomly allotted to 6 dietary treatments with 5 replicates of 14 chicks each (7 male and 7 female chicks). the cp levels were 17, 18, and 20 percent and lysine levels were ...

This study was designed to investigate the effects of different levels of Tarragon powder on performance, carcass characteristics of broiler chickens. Two hundred Ross 308 male broiler chickens were randomly allocated into four treatments and five replicates per treatment. At each replicate ten birds were used. Experimental diets were set on the basis of corn-soy-wheat and Ross 308 broiler chic...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

This study evaluated the effects of elevated incubation temperature on posthatch nutrient transporter gene expression, integrity of the intestinal epithelium, organ development, and performance in Ross 308 broiler chickens. Ross × Ross 308 fertile eggs (n = 900) were incubated at different eggshell temperatures during development. From embryonic day (ED) 1 to ED12, all eggs were incubated at 37...

the effects of dietary vitamin e levels on mucosal maltase and alkaline phosphatase (alp) enzyme activities and on the amount of mucosal malonyldialdehyde (mda) in broiler chickens were studied in the present study. one hundred and eighty of day old male broiler chicks (ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. chickens...

To study the effect of different levels of peppermint (Mentha piperita) plant powder, on immune system of broilers under heat stress condition, 192 one-day old chickens (Ross, 308) were randomly allocated to 4 dietary treatments with 4 replicates of 12 chicks each, using a completely randomized design. The four groups were characterized by a basal diet (control), basal diet supplemented with 1 ...

This study was conducted to investigate the effects of commercial probiotic mixtures (Liptosafe-L) via drinking water of broiler chickens in comparison with Antibiotic (Newmycin) on performance of Broiler Chicks and growth attributes. 120 broiler chicks (Ross 308) day old, and average weight of 41 grams, were subjected to a 41-day experimental period. The chick's were randomly divided into thre...
