- Nutritional parameters of steers receiving different levels of sunflower crushed in partial replacement of soybean meal HELLEN L. LIMA RAFAEL H.T.B. DE GOES SARA L.N. CERILO EUCLIDES R. DE OLIVEIRA MARIA G.M. GRESSLER KELLY C.S. BRABES Multidisciplinaria (Ciencias Naturales y Exactas) pH by ammonia product Fatty acid To evaluate of the sunflower crushed in nutritional parameters in steers, supplemented at pasture, we used four steers in 4x4 Latin square design. The supplements were provided in 6 g/kg of body weight/animal/day, consisting of sunflower crushed, corn, soybean meal and mineral. All the supplements was isonitrogenous and soybean meal was replaced in 0, 20, 40, and 60% for sunflower crushed. The determination of ruminal pH and ammonia was at 0, 2, 4, 6 and 8 h. after feeding and for short-chain fatty acids it was collected at 0 and 6 h. post-feeding. The dry matter intake was not affected ( P >0.05) by inclusion of sunflower crushed (mean=6.59 kg/day). There was no significant effect ( P >0.05) for pH for the inclusion of sunflower crushed (mean=6.41). For contents of ruminal NH 3 -N was a significant effect ( P <0.05) only for collection time, and ammonia peaks occurred between 2 and 4 h after feeding, with values of 22.56 and 21.40 mg/dL. The total concentration of short chain fatty acids and the C2:C3 ratio was reduced in 9.6 and 15.43%. The ruminal degradability of NDF was not affected by the supplements. The supplementation with sunflower crushed to beef steers grazing, in partial replacement of soybean meal did not alter nutrition parameters. 2013 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32729375029 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.85
