原始语种摘要: The goal of this study was to evaluate the effects of variable dietary metabolizable energy and crude protein concentrations on the performance, behaviour, expression of growth related genes and economic impact of broiler chickens. A total of 250 Cobb broiler chicks were divided randomly into five groups of ten replicates (10 chicks/replicate). Five diets with five different combinations of calories and protein were formulated as the following; normal energy and normal protein (NENP), low energy and high protein (LEHP), high energy and low protein (HELP), normal energy and low protein (NELP), low energy and normal protein (LENP) during starter and finisher period. The results revealed that the highest body weight and body weight gain were observed in the HELP and NELP groups which were...
