Abstract

Oil supplementation has abundance of benefit for animals due to its fatty acid content. Otherwise, oil supplementation is being limited due to its effect on coating feed in digestive system and lead animal to hardly digest others nutrient. Moreover, with proper treatment, animal may gain immense benefit from it. Much previous research was conducted on giving oil supplementation yet there are many things remain to be addressed. This article investigated the developing of oil supplementation and finding a gap to be filled to encourage the potential of oil supplementation in Indonesia. There are many items shown on this article such as types of oil, variables, level of oil supplementation and protection used. The result showed that in vivo method used more frequently than in vitro method and Lemuru fish oil was used most rather than another type of oil with the level was on 2 and 3%. Types of animals mostly used is sheep with parameters examined was digestibility. Much previous research also showed that many oil supplementation used protection treatment such as saponification. Furthermore, this article showed that there is mostly parameter used and types of animals and variety of oil supplementation in Indonesia.

Abstract

Concentrate can improve livestock productivity due to its high protein content. Meanwhile, a high proportion of concentrate consumption in livestock can decrease the pH of the rumen and lead to a decrease in rumen performance. Leguminous plants that have high protein and are abundantly available are a potential source of protein and concentrate substitutes in livestock diets. This study aimed to evaluate the effect of Leucaena leucocephala (LL) and Indigofera zollingeriana (IZ) as concentrate substitutes in RDP: RUP-concentrate-based diet on degradation of dry matter degradability (DMD) and organic matter (OMD), digestible neutral detergent fiber (dNDF), in vitro true digestibility (IVTD), pH value, NH3 concentration, and total gas production. This study used a Randomized Block Design, consisting of seven treatments with four replications. The treatments were: T1 = control consist of 40% Pennisetum clandestinum (PC) and 60% concentrate (C) (RDP: RUP of concentrate = 60%:40% of crude protein), T2 = 40% PC + 45% C + 15% LL, T3 = 40% PC + 45% C + 15% IZ, T4 = 40% PC + 30% C + 30% LL, T5 = 40% PC + 30% C + 30% IZ, T6 = 40% PC + 30% C + 15% LL + 15% IZ, T7 = 40% PC + 30% LL + 30% IZ. This study reported that leguminous as concentrate substitutes in RDP: RUP-concentrate-based diet significantly affected nutrient digestibility and total gas production, while pH value and NH3 concentration did not differ among experimental diets. The supplementation of LL 15-30% and IZ 15-30% in RDP: RUP-based diet increases DMD, OMD, IVTD, and total gas production. The combination of LL and IZ 15-30% in RDP: RUP-based diets tend to depress OMD, while other parameters did not differ among experimental diets. The highest DMD, OMD, IVTD, and total gas production were observed in the experimental diet with 30% of IZ substitutes in the RDP: RUP-concentrate-based diet. In conclusion, 30% Indigofera zollingeriana as a concentrate substitute in RDP: RUP-concentrate-based diet can increase nutrient digestibility and optimize rumen fermentation characteristics.
