This study conducted to evaluate the effect of prebiotics (Fermacto) and isoleucine and their combination on performance and some blood parameters of broiler chickens during finisher period. At the first of experiment 300 one-day-old mixed Ross broiler chicks reared in same condition according to Ross manual guide up to 21 days old. Chicks at 21 day old were randomly allocated to 20 groups of 1...

A total of 150 day old female chickens (Ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. The two experimental treatments were: 1) chicks that reared under normal temperature (NT) and 2) chicks that reared under cold tempe...

the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

the current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a completely randomized design. treatments were included: contro...

this study was designed to investigate the effects of different levels of tarragon powder on general performance and anetometric, properties of digestive system of male broiler chickens. 200 one-day-old ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. experimental diets were set on the bas...

background: in nature, there are herbal extracts, while capable of reducing aflatoxin b1 in agricultural product by different mechanisms, may also act as growth promoters. objectives: in this study, aqueous extract of t. daenensis was evaluated to detoxify contaminated feed with aflatoxin b1 and to determine the effect of growth promoters in japanese quail. methods: to this purpose, at 24 d of ...

Three hundred one-day-old male broilers (Ross 308) were allocated to five treatments with four replicates in a completely randomized design. Treatments supplemented with 0 (control), 400, 800, 1200 or 1600 ppb chromium in the form of chromium chloride. All birds were intramuscularly immunized with killed vaccine of Newcastle and Avian Influenza (H9 N2) virus at 8 d. On days 18 and 28 blood samp...

Background & Aim: Medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.This experiment was conducted to investigate the effects of milk thistle (MT) and thyme seeds (TS) on the performance in broilers. Experimental: In this study, 160 one-day-old (Ross 308) male broiler chicks were divided randomly into four major groups with 4 replicates b...
