The objective of the study was to determine the effect of increasing the ratio of SID TSAA to Lys in broiler chicks diets for 1 to 14 d of age on growth performance, efficiency of Lys utilization, caloric efficiency and carcass characteristics. In this study, 400 day-old straight-run Ross 308 broiler chicks sourced from a commercial hatchery were randomly allotted into 5 treatments following a Randomized Complete Block Design (RCBD). |
