Abstract
Three hundred and sixty, 2 weeks old, unsexed Cobb chicks were used in this study to evaluate the effect of low protein diets fortification with amino acids and Probiotic on productive performance, carcass traits and some blood constituents.
Two control diets (19 % C.P.) and (17% C.P.) and eight experimental groups depending on two levels of Lysine and Methionine (0.1 or 0.2%) supplemented to the 17% protein diets with or without supplementation of probiotic (1.0×109 C.F.U.UP Bacillus subtilis; Saccharomyces Cerevisiae) were investigated.
Chicks fed 17% CP diet with adding 0.2% methionine plus probiotic (Treatment 10) showed significantly (P<0.05) highest body weight, body weight gain and consumed the lowest significantly (P<0.05) amount of feed. Furthermore, the same treatment showed highest value of carcass quality except for gizzard. However there was no significant effect of treatment on plasma total protein.
