this experiment was conducted to evaluate the effects of using rice bran, combo multi-enzyme and probiotic (protexin) in diet on performance, egg traits, biochemical parameters and blood cells of commercial laying hens. this experiment carried out using 384 hi-line (w36) laying hens in a completely randomized design as factorial (2×2×2) arrangement with two levels of rice bran (0 and 10%), two ...

the effects of probiotics and antibiotics and fat type in diet on broiler performance were studied by using 900 one-day old ross 308 chicks in a three × three factorial arrangement with three types of fat (nonfat, three percent fatty acid and three percent soy oil) and three growth promoters (without gp, flavomycin and protexin) in completely randomized design with four replicates per each trea...

in this research to evaluate the effects of probiotic on the growth and some serum biochemical parameters of growing native kid’s, 24 kid’s, with 19.2± 0.7 kg body weight and 120± 10 days of age were used in a  completely randomized design with four treatments and six repeats. these four groups included: 1- the control group was fed on a basal diet (without probiotic or yeast). 2- the second gr...

the effects of probiotic (protexin) and formic acid were studied on humoral and cellular immunity in 200 cobb broiler chicks in a completely randomized design of with 4 treatments and 5 replications (10 observations per replicate). control group (c) did not receive any other than the base treatment. the chicks in the second (p), third (f) and forth (p+f) groups were fed with feed, which contain...
