One hundred and twenty two, one day old male Ross broiler chicks were used to evaluate the effect of Salkil, Prefect (two commercial feed additives) and Flavomycin (Antimicrobial growth promoter) on performance and on intestinal microflora. The chicks were divided into six groups: a) control with no additives, b) as control group but supplemented with 4 kg/ton Salkil during the whole period of the experiment (42 days), c) as control group but supplemented with 4 kg/ton Salkil during starting period and 2 kg/ton Salkil during the rest of the experiment, d) as control group but supplemented with

This study was conducted to evaluate the effect of feeding different levels of DDGS in the diets of tilapia fingerlings on growth performance, feed utilization, chemical composition of the whole fish body, blood hematological and economic efficiency. Therefore, five grading levels of DDGS ( 0, 5, 10, 15 and 20% ( D1- D5)) were used to replace soybean meal and yellow corn protein in approximately five isonitrogenous and isocaloric diets. Fish were stocked in a rearing plastic tank for two weeks adaptation period, then it were stocked at the rate of 5 fish/glass aquarium with initial weight of 6

One hundred and thirteen mid-lactation cows fed same diets and supplemented with 20 g/d rumen-protected methionine (RPM) for 8 weeks were used to investigate the individual responses of dairy cows to RPM in terms of lactation performance, amino acids (AA) metabolism, and milk metabolites. Among the cows, 10 cows exhibited positive responses (PR) and 10 cows showed limited responses (LR) in energy-corrected milk yield to RPM were used for further analysis. The lactation performance changed from gradual decline to steady increase in PR cows, while kept downward trend in LR cows following RPM sup
