Resumo

The aim of this study was to determine the intake and digestibility, nitrogen balance and ruminal fermentation parameters in sheep fed diets containing levels of substitution of soybean meal for soybean cake. The diets consisted of five levels of protein soybean meal (0, 25, 50, 75 and 100 %) by soybean cake. Diets were formulated with 12.5% CP, respecting the forage-to-concentrate ratio of 40:60.Tifton-85 hay was used as forage and the concentrate was formulated with corn, soybean meal, soybean cake and vitamin mineral supplement. Five crossbred lambs castrated, with average weight of 33.7 ± 5.8 kg were used and distributed in a Latin Square 5 × 5. No differences in intake and digestibility of dry matter, organic matter, crude protein, neutral detergent fiber, total carbohydrate, non-fiber carbohydrates and total digestible nutrients. Increased linearly in ether extract intake by replacing protein from soybean meal by soybean cake in the diet but with no changes in the digestibility of this component. The nitrogen balance, nitrogen content fecal and urinary retained were not influenced by levels of substitution of soybean meal by soybeans cake in diets. For the index pH and concentration of ammonia nitrogen in rumen fluid did not differ between diets. It was concluded that the soybean cake can be used as an alternative food to replace soybean meal up to 100% unless there are changes in the rumen parameters, balance of nitrogen, intake and nutrient digestibility.
