Resumo

ABSTRACT: The objective of this research was to evaluate the rates of fermentative losses and the recovery of dry matter from different silages of total feed mixture. The total feed mixtures consisted of diets based on forage palm, elephant grass, gliricidia and other ingredients such as sugar cane bagasse, corn bran, soybean meal and urea. 25 experimental silos were made, distributed in a completely randomized design, with five treatments and five replications. The treatments consisted of different mixtures of total feed. The diets were balanced to obtain isoproteic diets. The silos remained sealed for 90 days. After opening, the rates of losses by gases and effluents and the rate of recovery of dry matter from silages were evaluated. Analysis of variance was performed with the results obtained. The averages were compared using the Tukey Test, at 5% probability. The total feed silages composed of forage palm with sugarcane bagasse showed significantly higher values (P <0.05). Gas losses in forage palm silages, alone and in conjunction with elephant grass, as well as elephant grass silages, showed values close to 1% of DM losses. Elephant grass silages had lower effluent loss values (1.9803 kg / ton MV) than those found in forage palm silages and forage palm silages with sugarcane bagasse (2.7259 kg / ton MV and 2.4386 kg / ton MV, respectively). The dry matter recovery rates found in this experiment ranged from 87 to 98%. Forage palm silages, forage palm silages with elephant grass and elephant grass silages showed higher dry matter recovery rates (97.49%; 95.03% and 98.19%, respectively). The silage of forage palm with sugarcane bagasse is not indicated, due to the higher rate of losses.

KEYWORDS: gas production, forage palm silage, total diet silage.
