Digestibilidade e consumo de dietas em ovinos mantidos com misturas múltiplas, elaboradas com feno da parte aérea da mandioca (Manihot esculenta)

Abstract

The objective was to study the feasibility of using hay cassava foliage in the composition of multiple mixtures and the influence of partial and total substitution of soybean meal by hay cassava foliage, through an experiment in vivo digestibility. Five sheep were used, SRD, with three years of age and initial weight of 25 Kg The experiment was performed in the Latin square design with five treatments and five replications: T0 (without supplementation), T1 (0% de PAM) T2 (6,80% de PAM), T3 (13,20% de PAM) e T4 (20% de PAM). The dry matter digestibility coefficient (DMDC) of diets were 38,85% , 53,28%, 47,60%, 37,20% e 33,51% and DMCP were 17,76%, 69,31%, 66,60%, 36,9% e 36,55% to treatments with PS, T0, T1, T2 T3 e T4, respectively. The intake of DM (g/day) were 322,13g ; 676,65; 614,65g ; 534,31g ; 518,11g to T1, T2, T3 e T4. The intake of CP (g/day) was T0 - 16,14g, T1 – 61,38g, T2 – 60,95g, T3 – 43,58g e T4 – 47,16g. The use of PS was adequate to promote intake and digestibility, compared with diet without supplementation, thus increasing the digestibity of DM, CP and Fiber.
