Little information is available regarding the interaction of dietary Thr and Gly on the potential metabolic sparing effects, live production, or breast meat yield of broilers. To test these potential interactions, 432 one-day-old Ross 308 male broilers were fed a common diet up to 21 d of age, and then fed 1 of 6 experimental diets. A factorial arrangement of treatments consisted of 3 dietary levels of standardized digestible Thr (0.57, 0.61, and 0.65%) in combination with 2 levels of total Gly + Ser (1.55 and 1.65%). Experimental diets were fed from 21 to 42 d of age, with live performance, carcass traits, and free blood plasma levels of Gly, Ser, and Thr serving as evaluation criteria. Interactions (P ≤ 0.05) were observed for BW gain, feed consumption, carcass and breast meat weight, and carcass yield, all showing improvements with increasing dietary Thr in combination with low dietary Gly + Ser treatments. Circulating plasma Gly, Ser, and Thr were affected by their respective dietary status.

Key Words: threonine • glycine • broiler
