PERIPOLLI, Vanessa et al. Evaluation of soybean protein hulls in diets for sheep. Acta Sci., Anim. Sci. [online]. 2011, vol.33, n.2, pp.157-162. ISSN 1807-8672.

The aim was to evaluate the use of five levels of soybean protein hulls (0, 4, 8, 12 and 16%) in place of soybean meal in diets for sheep in confinement. We evaluated the performance, intake, nutrient digestibility and, energy and nitrogen balance in terms of diet. Twenty Texel lambs with an average weight of 28 kg were distributed in a completely randomized design with four replications. The diet consisted of 30% roughage and 70% concentrate. The soybean meal in the concentrates was gradually replaced by soybean protein hulls (SPH). Nutrient intake, feed-to-gain ratio and weight gain were not affected by increasing the inclusion level of SPH en the diet. SPH levels also did not influence the digestibility of DM, OM, N (CP), NDF and GE and the energy and nitrogen balance.

Keywords : nitrogen balance; intake; digestibility; by-product.
