The feeding of sheep for meat production in the Colombian Caribbean Region is based on the use of grasses by virtue of their low costs. However, the yields and nutritional quality are affected by the seasonality of the rains, so there are low weight gains. The objective of this work was to evaluate the effect of the supplementation with cotton seed and corn grain on the productive performance and quality of the meat of sheep creole of Colombian hair. The study was carried out in the the Faculty of Veterinary Medicine and Zootechnics of the University of Córdoba, Ciénaga de Oro-Colombia. Twenty four male creole lambs with initial weight of 16 ± 2 kg were used, which were randomly distributed in four experimental treatments consisting of: T0: Grazing, T1: Grazing + 25% cottonseed (CS) + 75% corn (C), T2: Grazing + 50CS+50%C and T3: Grazing + 75% CS+25%C. Animals were weighed at the start of the experimental phase and every 15 days. The following variables were studied: weight of the hot and cold carcass, performance of the cold carcass, carcass length, leg perimeter, thoracic perimeter, covering fat, compactness index, humidity, pH, water retention capacity and color. The weight gain differed (p≤0.05) between treatment, presenting mean values of 0.053; 0.126; 0.128; 0.130kg for T0, T1, T2 and T3, respectively. Similarly, differences (p≤0.05) were detected for carcass weights and yields. The supplementation with cottonseed and corn improved the productive performance of the animals, being reflected in greater gains of weights and yields.
