Abstract
The aim of this study was to evaluate protected of soybean oil and soybean groats as feed supplement based on dry matter digestibility, organic matter digestibility in vitro in the rumen and post-rumen. Protected feed supplement was produced from soybean oil through two protection methods. It was saponification and microencapsulation. Soybean groats protected through formaldehyde 1%. This research uses a completely randomized design with 3 treatments which each treatment was repeated 10 times. Treatments were P0: 40% elephant grass + 60 basal concentrate; P1: 40% elephant grass + 50 basal concentrate + 10% soybean oil and soybean groats protected; P2: 40% elephant grass + 45 basal concentrate + 15% soybean oil and soybean groats protected. The results in the first step (rumen) of the P0 showed that has dry matter digestibility 69.50% and organic matter digestibility 69.74%, P1 has dry matter digestibility 50.07% and organic matter digestibility 52.55%, and P2 has dry matter digestibility 48,45% and organic matter digestibility 49.75%. In the second step (post rumen) the digestibility of P0 has dry matter digestibility 70.64% and organic matter digestibility 70.85%, P1has dry matter digestibility 70.56% and organic matter digestibility 71.74%, and P2 has dry matter digestibility 73.17% and organic matter digestibility 73,86%. The results could be concluded that in the rumen protected of soybean oil and soybean groats have more resistant (stable) to microbial degradation than the basal diet and it can be degraded and digested in the abomasum to the small intestine.
