Efek Perbedaan Komposisi Konsentrat terhadap Perbaikan Nilai Nutrisi Jerami Padi

Abstract


Since rice straw is seasonal and low quality roughage, thus, a supplementation for it is needed. Lamtoro leaf meal (LLM) and soybean meal (SBM), have both soluble and bypass protein, so it enough potential to supply nutrients to optimize of rumen microbes and improve animal performance. Supplementation with LLM or SBM significantly increased dry matter, organic matter, crude protein and crude fiber intake (P<0.05). This fact showed that LLM or SBM supplementation made an improvement of rumen fermentation by microbes. Comparison between LLM and SBM to basal diet clearly showed that basal diet was the lowest (P<0.05) nutrient intake and nutrient digestibility, however, the animal fed basal diet degraded crude fiber was not affected. It has been shown that supplementation with lamtoro leaf meal or soybean meal were palatable, fermentable and reasonably digestible. Therefore, the use of these feedstuffs as  supplement to rice straw are strongly recommended.
