Abstract
The objective of this study was to investigate the influence of phytate on growth performance in Ross 308 broiler chickens offered different levels of digestible lysine, starch and lipid in twelve maize-soy diets from 7 to 28 days post-hatch. Diets with high lysine:starch ratios generated lower feed intakes (P < 0.001) and diets with higher lipid concentrations reduced weight gains (P < 0.005). Importantly, there were interactions (P < 0.01) between dietary phytate-P concentrations and lysine:starch ratios for weight gain and FCR. Phytate had a more pronounced negative impact on growth performance in broiler chickens offered diets with low digestible lysine and high starch levels.
