Desempenho e digestibilidade de nutrientes em ovinos alimentados com rações contendo farelo de babaçu

Abstract 

With the objective to evaluate the performance, voluntary intake and nutrient digestibilities, 24 NDB (no defined breed), non castrated male lambs with 20 ± 3.25 BW initial and 4.6 ± 0.8 months old were used. Animals were kept in feedlot and fed diets with babassu meal (0, 10, 20 and 30%) in substitution to Panicum maximum Jack hay. The diets, isoprotein and isonitrogenous, were fed in a complete mix ration. A completely blocks randomized design, with four treatments and six replicates was used. The dry matter intake was influenced by the inclusion of babassu meal in the diet and presented a reduction of 302 g/day for each 10% of babassu meal inclusion. Nutrient intake and performance were limited by the decrease of dry matter intake. The inclusion of babassu meal caused a linear decrease on average daily gain of lambs. Nutrient digestibility was influenced by inclusion of babassu meal in the diet, but this increase was a result of the reduction on dry matter intake. Babassu meal, used as an alternative feed for growing sheep, affect nutrient intake and weight gain of the animals.
