Abstract: Our objective was to evaluate the effect of 15% crude protein (CP) and total digestible nutrient (TDN) restriction vis-á-vis that recommended by NRC (2007) on feed intake, digestibility, and average daily gain (ADG) of confined Morada Nova lambs. Twenty lambs with 18.8 ± 2.8 kg liveweight were assigned to a randomized 2 × 2 factorial experiment with either early- or late-maturity feed formulation according to ?Nutrient Requirements of Small Ruminants? with or without 15% CP and TDN restriction. The early-maturity diet, independent of restriction, resulted in greater dry matter and organic matter intake and increased rumination efficiency and feed conversion. Early-maturity diets also had the greatest nutrient digestibility as well as ADG and total gains. With late-maturity diets, independent of restriction, there were greater CP and TDN digestibilities as well as neutral detergent fiber (NDF) feed efficiency. However, when 15% of nutrients were restricted for late-maturity lamb diets, there was greater NDF intake and greater ether extract digestibility. Unrestricted early-maturity lamb diets was the better diet for confined Morada Nova lambs. Attention should be given to minimum effective NDF consumed and physically effective for this diet formulation. The use of late-maturity diets as recommended by NRC (2007) allows for 15% restriction of CP and TDN in Morada Nova lambs without negative effects on performance. This restriction should be tested in other tropical breeds to determine wider application.
