DEVELOPMENT OF A CATTLE FOOD FROM EXCESS BAGASSE USING SOLID FERMENTATION

摘要

In order to contribute to the sustainability of the cattle and sugar industries, a feed from excess bagasse was developed. We used two sources of nitrogen: urea and molasses sugar concentrate (CMS), in three proportions (100:0, 50:50, 0:100) with three levels of grain (0%, 10%, 15%) using 5 replicates, in a completely randomised design with a factorial arrangement (3 x 3). All ingredients were mixed and added with 15% of inoculum from fermented sugarcane. The mixtures were left on the floor (10 cm height), in order to promote aerobic fermentation (24 h). Then, the mixtures were ensiled for 0, 1, 3, 5, 10, 15, 30, 45 days. At each time, samples were analysed for dry matter, pH, temperature, protein, and lactic acid. Results showed increases in true protein, lactic acid and a pH between 3.8 and 5.0. On days 30 and 45, the temperature was raised, which caused protein degradation and an increase in pH. Dry matter of the silage was between 30 and 40%. It was concluded that the excess bagasse is a by-product that can be incorporated in the manufacture of feed for cattle.
