Abstract

This study was carried out with the objective of determination of the optimal standardized ileal digestible lysine level in starter period (8 to28 days old) based on the performance, blood parameters and immune response in male turkey poults. A total of 160 male turkey poults(BUT6) in a completely randomized design, using eight treatments(1.33(basal diet),1.405,1.48,1.55,1.63,1.705,1.78,1.855% SID Lys)  and four replications, with 5 birds in each. Diets were isoenergetic, isonitrogenous and equal in electrolyte balance. There was a significant effect of standardized ileal digestible lysine levels on performance and blood parameters. Increase of digestible lysine level to 1.705% resulted in improved of body weight, FCR, H/L ratio,total protein, albumin and uric acid. Increasing SID Lys levels increased WBC number. At the end of this experiment increased of SID Lys levels improved of performance, blood parameters and immunity.
