Abstract

Digestibility is an indication of the presence of nutrient available in the feed ingredient consumed by livestock. The quality of nutrient is determined by the level of digestion of the food substances absorbed in the digestive tract. This research aimed to evaluate the dry matter digestibility (DMD), organic matter digestibility (OMD), concentration of volatile fatty acid (VFA) and N NH3 with the addition of local feed Supan supan (Neptunia plena L. Benth) and Kolomento (Leersia hexandra Swartz). The reseach was conducted on January 2018 in Animal Feed and Nutrition Laboratory of Animal Husbandry and Agriculture Faculty, Diponegoro University, Semarang. The research method used in vitro analysis with completely randomized design with five treatments is T1 (Leersia hexandra Swartz 100 %); T2 (Neptunia plena 100%); T3 (Leersia hexandra 15%+(Neptunia plena L. Benth 15%+70% Other Feedstuffs); T4 (Leersia hexandra 20%+(Neptunia plena 20% + 60% Other Feedstuffs); T5 (Leersia hexandra Swartz 25% + (Neptunia plena L. Benth 25%+50% Other Feedstuffs). The data were analyzed with analysis of variance at 95% significant level, followed by Duncan Multiple Range Test. The resource results showed that the treatment had significant impact (P<0.05) to KcBK, KcBO, N NH3, and VFA. The results indicated that T3 has the best KcBK and KcBO 40.13% and 46.63%. The best production of N NH3 contained in T2=8.18 mM and the best VFA T5=50.21 mM. It was concluded that use of local feedstuffs by quantity can contribute to the production of goats.
