Abstract
Broiler chickens were offered diets formulated to contain 200, 188, 172 and 156 g/kg crude protein (CP) from 14 to 35 days post-hatch. Feed conversion ratio (FCR) increased linearly from 1.495 to 1.629 as dietary CP declined with a corresponding increase in distal jejunal starch-protein disappearance rate ratios from 2.08 to 3.17. These two parameters were quadratically related (r = 0.838; P < 0.001) and there was a linear relationship (r = 0.605; P < 0.001) between relative fat-pad weights and FCR. Increasing starch-protein disappearance rate ratios are detrimental for birds offered CP-reduced diets and the implications of these outcomes are discussed.
