in order to study the effect of different levels of desiccated ox bile (dob; 0.00, 0.25, and 0.50%) and organic acid (oa; 0.00, 0.15, and 0.30% of the diet) on performance, fat digestibility, blood metabolites and ileal digesta viscosity in broiler chickens fed diets containing 5% tallow, in a completely randomized design with a 3×3 factorial arrangement and 4 replicates in each treatment, 360 ...

this research was conducted to evaluate the effects of adding five levels of ferula assa foetida powder (0, 0.25, 0.50, 0.75 and 1 percent of diet) on performance, humoral and cellular immune status and cecal microbial population. a total of 200 one-day-old mixed sex ross 308 broiler chicks were randomly assigned to 5 experimental groups with each four replicates and 10 birds in each replicate,...

An experiment was conducted to estimate optimal dietary arginine requirement in White Pekin ducks from 1 to 21 d of age. Six hundred thirty 1-d-old male White Pekin ducks were randomly allotted to 10 dietary treatments with 7 replicate pens of 9 birds per pen. Birds in each group were fed corn-corn gluten meals diet containing 0.71, 0.84, 0.95, 1.03, 1.17, 1.27, 1.39, 1.47, 1.62, and 1.72% argi...

Factors to standardize litter weights of nursing pigs to 21 d of age were calculated from daily weights measured on 64 crossbred litters from 10 to 32 d of age. The results were compared to published factors derived from a data set of Duroc pigs weighed every 3 to 4 d. Dams in the present study were white crossbred sows and gilts, and sires were maternal or terminal breed types. Multiplicative ...

in this experiment, randomized complete block design with four replications was used for evaluating of the effect of three feeding methods including: without feed restriction (control group), 6 hours feed restriction from 7 to 21 days and 4 hours from 22 to 28 days, 6 hours feed restriction from 7 to 14 days and 4 hours from 15 to 21 days on performance and ascites prevention of arian male broi...
