PENGARUH PROTEKSI PROTEIN BUNGKIL KEDELAI DENGAN CAIRAN BATANG PISANG TERHADAP KONSENTRASI AMONIA DAN UNDEGRADED DIETARY PROTEIN (UDP) PADA RUMEN DOMBA (IN VITRO)

This research goal is to determine the protein protection of soybean meal with tannin of banana stem liquid on ammonia concentration and undegraded dietary protein in sheep rumen (in vitro). The research was held at Ruminant Nutrition and Feed Chemistry Laboratory of Animal Husbandry Faculty, Universitas Padjadjaran. The reseacrh used experimental method with Completely Randomized Design (CRD) with four treatments and each treatment was repeated five times. The treatments were arranged as follows: T0 (soybean meal + tannin 0%); T1 (soybean meal + tannin 0.5%); T2 (soybean meal + tannin 1%), and T3 (soybean meal + tannin 1.5%). The data were analyzed by Polynomial Orthogonal and Duncan test. The result of the research showed that protein protection of soybean meal with tannin of banana stem liquid decreased ammonia concentration (P<0,05) significanly with equation y=6.267-11,27x+16x2-6.2x3 (R2 =0.803) and increased undegraded dietary protein (P<0,05) with equation y=29.224+17.025x (R2=0.955). Lowest concentration ammonia was resulted by T1 (soybean meal + tannin 0.5%) and Highest concentration Undegraded Dietary Protein was resulted by T3 (soybean meal + tannin 1.5%).
