Abstract

The ruminal degradation of corn silage, sugar cane and soybean meal, contained in feeding diets, were evaluated in four Holstein cows, with rumen cannulae, in a statistical design of 4 x 4 latin square. The diets presented 59.4% (DM basis) of roughage at the proportions: A) 1:0, B) 1/3:2/3, C) 2/3:1/3 and D) 0:1 of corn silage and sugar cane respectively. The concentrate (40.6% of the diet) raised the crude protein content up to 15%. Simultaneously, it was carried out with the same animal, a study of the digestibility of such diets. Using sheep in an experiment totally randomised, it was held a study on the apparent digestibility and nitrogen balance. The DM intake by the animals receiving the different diets were similar (P>0.05). Best results of the nutrient digestibility were obtained with the diet containing only sugar cane. The type of roughage in the diets did not affect the N balance in sheep. A part of the experimental diets, sugar cane showed higher proportions of instantaneously soluble fractions and lower of insoluble ones, but potentially degradable. Higher quantities of sugar cane in diets increased potential of degradation of DM from the food incubated, from the NDF in sugar cane and from the PB soybean meal.
