Digestibilidade e consumo de dietas, por ovinos, mantidos com misturas múltiplas, elaborados com farelo de babaçu

Abstract

The objective of this research was to evaluate the use of babaçu meal (BM) in composition of protein supplements (PS) and the influence of partial or total substitution of soybean meal (SM) for babaçu meal, trough in vivo digestibility trial. There were utilized five sheep without defined breed eating hay of Napier grass of 90 days as the unique roughed. The design was change-over, with five treatments and five repetitions: T0 (mineral supplement + hay); T1 (0% de BM; 20% SM), T2 (6,80% de BM; 13,20% SM), T3 (13,20% de BM; 6,8% SM) e T4 (20% de BM) – from T1 to T4, in all PS. 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 T0, T1, T2 T3 e T4, respectively. The intake of DM (per day) were 322,13g ; 676,65; 614,65g ; 534,31g ; 518,11g to T1, T2, T3 e T4. The intake of CP (per 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. BM could used until 33,33% substituting soybean meal to produce the best intake and nutrient digestibility standards.
