• Abstract:

  This paper aimed to evaluate the effect of different levels of a commercial additive composed by aluminosilicates, named Beefplus, on intake and apparent digestibility of nutrients, and metabolism of nitrogenous compounds. Five male Nellore cattle, with ruminal fistula, were distributed in a 5×5 Latin square, consisting of five treatments (levels of aluminosilicates: 0.0; 0.5; 1.0; 1.5 and 2.0%, in DM basis) and five experimental periods, of 15 days each, totaling 75 days of experiment. The basal diet consisted of 40% corn silage and 60% concentrate made with cornmeal and soybean meal. Adaptation to the diet occurred from the 1st to the 10th day of each period, in the subsequent five days (from the 11th to the 15th day), total feces collections were performed. During the collection period, samples of silage, concentrates, and leftovers were made for further analysis. There was no effect of aluminosilicates levels (P>0.05) on nutrient intake and digestibility. There was no effect (P>0.05) of the addition of aluminosilicates on the metabolism of nitrogenous compounds. It was concluded that the addition of aluminosilicates does not alter nutrient intake and digestibility.
