Daftar Isi:
- The objective of this research was to determine the effect of supplementation with protected polyunsaturated fatty acids (PUFAs) in the feeding of beef cattle based on the rumen fermentation and the nutrients digestibility parameters by in vitro. PUFA source is derived from soy groats as a source of linolenic fatty acids and lemuru fish oil as a source of linoleic fatty acids. This research has been carried out in the Laboratory of Nutritional Biochemistry Faculty of Animal Science, Gadjah Mada University in Indonesia. Fermentation was observed at 48 hours after incubation by in vitro. Rumen fluid were taken from the Ongole crossbred cow fistulated. Protection use the 37% formaldehyde are made dry matter 2% mixture of soy groats and lemuru fish oil (SoyLem) with a ratio of 4:1. Feed treatments including T1 = 30% elephant grass + 30% rice straw + 25% basal concentrate + 15% SoyLem unprotected, T2 = 30% elephant grass + 30% rice straw + 25% basal concentrate + 7.5% SoyLem unprotected + 7.5% SoyLem protected, and T3 = = 30% elephant grass + 30% rice straw + 25% basal concentrate + 15% SoyLem protected. The results of this study were the rumen fermentation in vitro showed the microbial protein, the number of protozoa, ammonia significantly different (P <0.05) and VFA levels highly significant (P <0.01), while pH, CMCase, and the ratio of astetat acid:propionic not significantly different (P> 0.05). Digestibility of dry matter, organic matter, protein, fat, and crude fiber were significantly different (P <0.05) between treatments. It was concluded that a mixture of soy groats and lemuru fish oil (4:1) 2% formaldehyde protected can be used as a supplement by 15% in cattle feed without disturbing the fermentation and nutrient digestibility by in vitro
