In a completely randomized design, 600 commercial day old broiler chickens were used to study the possibility of replacing corn with barley. Each of 10 experimental diets in which corn was replaced with barley at levels of 0, 5, 10, 20 and 40 percent, with and without tallow, were given to 4 replicates of 15 chickens each. At 42, 49 and 56th days of age, one male and one female from each pen we...

In order to investigate the effect of phytase and copper supplementaion on growth and carcass composition of common carp (Cyprinus carpio L.), in a completely randomized design with 3 ×2 factorial arrangement with three replicates the experimental diets including three levels of phytase 0, 500 and 1000 (FYT) kg-1 and two levels of copper 0 and 15 mg/kg were tested. Diets contained 0.72 percent ...

The present study was performed to investigate the effects of dietary electrolyte balance and probiotic on the performance and carcass characteristics in Japanese quail under heat stress conditions. A total of 672 quail chicks (20-day old) were studied in a three-factor, factorial experiment with 4 replicates and in each replication of 14 birds during 20 to 37 and 20 to 41 days Factors included...

This research was conducted to investigate the effect of different levels of metabolisable energy and crude protein on performance, carcass characteristics and blood parameters of Japanese quail during grower phase (14-28 d of age). Nine hundreds 14-d-old male birds were used to examine 3 levels of energy (2900, 3050 and 3200 Kcal of ME/Kg of the diet) and 3 levels of protein (21.6, 24 and 26.4...
