To determine the effect of D-Pro probiotics (Bacillus licheniformis, Bacillus subtilis) and Saccharomyces cerevisiae in Persian sturgeon’s diet on the growth indices and biochemical analysis of the carcass, a total of 2400 Persian sturgeon species were randomly selected, with a mean weight of 4.00±0.10 g (mean ± standard error) and a mean length of 9.91±0.35 cm (mean ± standard error), and were...

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 ...

This study was carried out to evaluate the duration of time of feeding starter and finisher diets on live performance and carcass characteristics of female broilers. Starter diet was fed to 14 or 21 days of age. Finisher diet was fed beginning at 35 or 42 days up to 49 days of age. The results indicated that reduction of duration of feeding starter diet reduced weight gain (P<0.0071) and impair...
