Abstract

A total of 480 one-day-old male turkey (B.U.T.6) were assigned to eight treatments with six replicates and 10 birds in each replicate in a 4x2 factorial arrangement. Treatment groups were four ideal ratios of digestible Arg to Lys (85, 95, 105, and 115%) and two levels of CreAmino (0 and 0.06%) as a guanidino acetic acid (GAA) source. Body weight gains (BWG), feed conversion ratio (FCR) and feed intake (FI) were measured during two periods of starter (0-21d) and grower (22-49d). At the end of experiment (49 d) two birds per replicate were selected and slanghtered and their carcass traits were measured. The main effect of Arg:Lys on BWG was significant during starter period (P<0.05). Birds fed diets with 85 % Arg:Lys ratio without GAA had significantly lower BWG compared to 105 and 115 % ratios (P<0.05). Dietary supplementation of GAA improved the lower BWG. During the growing and overall periods, dietary addition of GAA significantly decreased FI (P<0.05). FCR was significantly higher for birds fed diets with 85% digestible Arg:Lys compared to the higher Arg:Lys ratios at starter period (P<0.05). Dietary supplementation of GAA (0.06%) significantly improved FCR (P<0.05). The main effect of GAA addition (0.06%) was significant for carcass, breast and wing yield (P<0.05). Rresults of the current experiment showed tha dietary GAA supplementation has a potential to compensate low Arg:Lys ratio in turkey poults, leading to improved growth performance.
