Degradability of Rumen-Protected Soybean Meal with Different Temperatures and Heating Times in Bali Cattle

The goal of this study was to ascertain the impact soybean meal's temperature and heating duration as undegraded protein (UDP) on Bali cattle's dry matter (DM) organic (OM) degradation kinetics. Soybean meal is a feed ingredient with high content, which about 48%, rapidly degraded in rumen. In investigation, factorial design employed first factor being (60, 80, 100, 120°C), second time (10, 20, 30, 40 min). Protected tested for using sacco technique rumen fistulous cattle. A sample 5.0 g put into nylon bag then 0, 2, 4, 8, 16, 24, 48 h rumen, analyzed residues DM OM. results showed that protected by method could reduce OM (p<0.05). Heating at 120°C min lowest degradations study.
