Un total de 27 corderos machos enteros de la raza Pelibuey, en la etapa crecimiento-ceba, con un peso inicial promedio de 19,9 kg, se utilizaron con el objetivo de estudiar tres niveles de inclusión de cama de pollo de cascarilla de café en la dieta: T1) 0 g/kg de PV; T2) 12 g/kg PV y T3) 20 g/kg PV. Los animales permanecieron pastando 6,5 horas cada día y al final de este se le suministró el suplemento de pollinaza más 6 g de miel final/kg PV. A los 90 días de la prueba se obtuvo que el peso vivo final (T1: 27,0; T2: 29,0 y T3: 30,8 kg) se incrementó significativamente (PA total of 27 Pelibuey non-castrated male lambs, in the growing-fattening stage, with an initial average weight of 19,9 kg, were used with the objective of studying three inclusion levels of chicken litter of coffee shells in the diet:T1) 0 g/kg LW; T2) 12 g/kg LW and T3) 20 g/kg LW. The animals remained grazing 6,5 hours each day and at the end of it they were offered the supplement of chicken dung plus 6 g of final molasses/kg LW.
