Abstract:

At present, there is a need to supplement with leguminous foliage Pelibuey sheep. The objective of the present investigation was to evaluate the productive behavior of this species during lactation, supplemented with Leucaena leucocephala (Ll). The experiment covered a period of five months, 63 breeding animals were used. In the control group, the main source of protein was the concentrate, in the second and third were supplemented with 25 and 35%, respectively, of the aforementioned plant, distributed in a completely randomized design with three treatments according to the level of inclusion of the leguminous and three repetitions (seven animals for each one); The data were processed using a simple classification variance analysis. The indicators of live weight of the pups at weaning and breeding were evaluated at the beginning and end of lactation and milk production (MP). The results showed that the MP peak was in the fourth week with values of 1.30; 1.29 and 1.38 for treatments I; II and III, respectively, and began to fall in the octave to 16 (0.50, 0.50 and 0,49 L for I, II and III, respectively). It was concluded that feeding system with Leucaena leucocephala constitutes an efficient alternative in the nutrition of the sheep favoring the productive indicators at the end of lactation and of the weaned offspring.
