Ingestive behavior of sheep fed elephant grass silages with the addition of coffee hulls, cocoa meal or cassava meal

The experiment was carried out to evaluate the ingestive behavior of sheep fed diets containing elephant grass silage with different additives. Twenty sheep non-castrated male kids were used in a randomized complete design, with four treatments and five replications. The treatments were: elephant grass silage (control); elephant grass silage (75%) + coffee hulls (15%); elephant grass silage (75%) + cocoa meal (15%) and elephant grass silage (75%) + cassava meal (15%). The additives were added at ensilage moment was realized in natural matter basis (weight/weight). The animals received diets with 11% protein in 60% forage and 40% concentrate proportion, on dry matter basis. The behavior variables were obtained every ten minutes during 24 hours of observation. The time spent feeding and ruminating was similar for the different silages. However, the animals that consumed diets with elephant grass silage with the addition of cassava meal showed higher idle time. The dry matter intake and the feeding (g of DM and NDF/h) and ruminating (g DM/h) efficiency were higher for diets with elephant grass silage with addition of 15% cassava meal, that was shown to be a good additive for use in elephant grass ensilage. The inclusion of cassava meal positively affected some parameters of ingestive behavior.
