FRACIONAMENTO DE PROTEÍNAS DE SILAGEM DE CAPIM-ELEFANTE EMURCHECIDO OU COM FARELO DE CACAU

The experiment was conducted to determine the fractions that compose the protein of silage on the submitted elephant grass forage to wilting under the sun light for eight hours. Other treatments involved the same elephant grass without exposing to sun light but with addition of 0, 7, 14, 21, and 28% of cocoa meal (CM) at the ensilage processing. The PVC silos used in the experiment were 5.3 liters in capacity, and were opened in 45 days. To all protein-estimated fractions, the wilted treatment showed similar values (P>.05) to the treatment without wilting. The protein fractions were influenced by CM addictions, verifying reduction in contents of A and B1+B2 fractions and increase in B3 and C fractions, with CM increasing levels.
