Quality of BRS kurumi ensilage associated with different additives | Quality of BRS kurumi ensilage associated with different additives

Английский. The objective of this study was to evaluate the impact of different additives in elephant grass silage, cultivar BRS Kurumi, on the nutritional quality of forage in the municipality of Campos Borges, RS. The forage was harvested when the canopy reached 72 cm, cut 10 cm from the ground and exposed for 24 hours to wither. It was then crushed and divided into treatments with and without additives: pure silage; addition of corn bran; addition of wheat bran; addition of rice bran; addition of cassava root; addition of orange pomace. After 66 days, the samples were analyzed for the nutritional characteristics of the silage. The results showed dry matter variation of 17.1% to 20.7% between treatments. The treatments with corn bran, rice bran and orange pomace showed higher levels of crude protein than the other treatments. The lack of rain during the production cycle favored the accumulation of stalks, making dehydration and the increase in dry matter difficult, compromising lactic fermentation and reducing pH. The addition of additives has proven to be an effective strategy to improve the quality of ensiled forage, incorporating soluble carbohydrates, precursors of VFAs.
