This study aims to examine broiler chickens’ response brown sugar with different levels of turmeric in drinking water. The was conducted the Department Animal Husbandry housing unit, Faculty Agriculture, Pattimura University, using 90 unsexed Cobb strain chickens aged 1 day, randomized into three treatment groups following a completely design 3 x 5 directional pattern. consisted P0: feed + wate...

To calculate partial and total productivity of production factors in broiler farms in Yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. To measure productivity, the Cobb-Douglas production function was estimated using classic and fuzzy regression met...

in this study the effect of diet dilution in 16-20 d of age and using a multi-enzyme (endofeed-w) on performance, carcass characteristics and some blood parameters of broiler chickens (cobb 500, commercial strain) was studied. this experiment was conducted as a factorial arrangement 2×3 in a completely randomized design with 3 replicates and 8 chicks in each replicate. experimental diets contai...

Genetic improvement through intensive selection in broilers for economically important traits such as body weight, growth rate, feed efficiency, and carcass quality plays a role increasing the productivity efficiency of broiler industry. Good maintenance management is needed by paying attention to quantity well comfortable controlled environmental conditions. The factor that often focus tempera...

Lysine maize (Zea mays), LY038, was developed through the application of modern biotechnology to accumulate free Lys in the germ portion of maize grain and provide an alternative to direct addition of supplemental Lys to poultry diets. Maize LY038 x MON 810 was produced by conventional breeding of LY038 with MON 810, which provides the corn plant protection against feeding damage from the Europ...

The present study was conducted to investigate the effect of dietary supplementation of turmeric (TEO) and rosemary (REO) essential oils on growth performance and oxidative stability of broiler meat. Five hundred forty day-old chickens (Cobb 500) were randomly allotted to a 3 × 3 factorial arrangement with three levels of turmeric essential oil (T1=0, T2=75 and T3=150 mg/kg) and three levels of...

The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...

background: no study has been conducted on iron requirements of broiler breeder hens until now. objectives: the purpose of the present study was to determine the iron requirement of broiler breeder hens using nonlinear models. methods: forty eight (cobb 500) broiler breeder hens were individually placed in galvanized wire cages. in order to depletion of hens iron reserved, hens were offered a s...
