Resumen
Twenty Dorper X Pelibuey crossbred lambs (24.5 kg initial live weight 3-4 months old), they were held for the course of 60 days in a metallic barnayrd with individual food and water treys, were used to evaluate the effects of substituting fresh orange pulp (FOP) by buffel grass hay (BGH) in finishing diets on lamb productive performance (daily weight gain, DWG, feed consumption, FC and feed conversion FCV) and on apparent digestibility of dry matter (ADDM). All lambs were maintained in steel cages, fitted with individual feeders and water drinkers during the study. Rations as fed were prepared daily, for each group and each animal, giving each lamb free choice of feed and water, according to their individual body weight. A total of five treatments (T) were used, where the level of FOP was substituted by BGH (FOP:BGH ratio), to offer 40 % of total fiber, as follows, T0 = 40:0, T1 = 30:10, T2 = 20:20, T3 = 10:30, y T4 = 0:40 %. Feed was prepared daily and feed and fresh water were offered daily and ad lib. A quadratic effect (P Se utilizaron 20 corderos Dorper x Pelibuey (24.5 kg de peso vivo inicial, 3-4 meses de edad), que fueron alojados durante 60 días en corraletas metálicas con comederos y bebederos individuales, para evaluar el efecto de sustitución de pulpa fresca de naranja (PFN) por forraje (Heno de zacate buffel, HZB) sobre el comportamiento productivo (Ganancia de peso, GDP, consumo, CDA, y conversión de alimento, CA) y la digestibilidad aparente de la materia seca (DAMS), en dietas integrales para corderos en finalización. Se utilizaron cinco tratamientos como niveles de PFN en sustitución por HZB (Proporción PFN:HZB, T0 = 40:0, T1 = 30:10, T2 = 20:20, T3 = 10:30, y T4 = 0:40 %). Las dietas y agua fresca se proporcionaron diariamente y a libre acceso. El alimento ofrecido y rechazado se pesó diariamente. Se observó un efecto cuadrático de la sustitución del HZB por PNF (P
