| Popis: | Rumen digesta disposal from slaughterhouses is a significant problem due to causes environmental pollution. However, it is valuable waste that is potent to use as a supplement on animal diet considering its rich in nutrients. Moreover, additional natural substances on rumen digesta improved feed efficiency. Thus, this research aimed to evince the effectiveness of rumen digesta supplementation enriched with natural sources for enhancing the quality of animal diet and cattle performance. The study was conducted on a cattle farm of Ngablak, Magelang Regency. Four formulations of rumen digesta were fed to five male cattle (Holstein-Friesian crossbred) in a completely randomized experimental design, namely: (1) RCS: rumen digesta enriched with cassava leaves, (2) RKD: rumen digesta enriched with moringa leaves and soybean powder, (3) RKC: rumen digesta enriched with moringa leaves and cassava chips, (4) RKS: rumen digesta enriched with moringa leaves and milk. The rumen digesta were processed through anaerobic fermentation for 21 days, then mixed with other feedstuff components, including rice straws, grasses, rice bran, molasses, table salts, and commercial mineral. The utilization of RKS rumen digesta resulted in the best nutritional value of feed indicated by high crude protein (10.24% DM), lipid (3.37% DM), and crude fiber (28.5% DM). Moreover, feeding cattle with the RKS diet significantly gained the cattle body weight up to 1.24 kg/day. |
