Penurunan Total Tanin Silase Semak Bunga Putih (Chromolaena odorata) dengan Aditif Tepung Putak (Coryphaelata robx) dan Isi Rumen Sapi

Abstract

This study was aimed to assess the effect of the addition of putak meal (as a source of carbohydrates) and rumen content (as a source of enzymes) in the making of C. odorata silage to the total content of tannins and nutrient content of C. odorata silage. The treatments were: CO (C. odorata), COP (C. odorata + 10% of putak meal), COPR5 (C. odorata + 10% of putak meal + 5% of rumen content), and COPR10 (C. odorata + 10% of putak meal + 10% of rumen content). The experimental design used was Completely Randomized Design, with 4 x 2 factorial patterns. The first factor was the treatment (CO, COP, COPR4, COPR10) and the second factor is the silage fermentation time (0 days and 21 days). Each treatment was replicated 4 times. The variables measured were concentration of total tannin content and nutrient content. The results showed that the addition of (10% of putak meal and 10% of rumen content) decrease total tannins of the silage by 15.50%. The nutrient content (OM and OP) increased by 3.45% and 41.81% respectively as well as a decline in crude fiber 3% when compared to the silage without additives. Fermentation time of C. odorata silage for 21 days produced the best quality silage fermentation time compared to 0 days.
