Rumen Fermentation Optimization of Kacang Goats Fed Complete Silage-Based Feed Sorghum-Clitoria ternatea with Various Concentrate Levels Contains ZnSO4 and Zn-Cu Isoleucinate

Abstract

This research was conducted to determine fermentation in the rumen, consumption, and digestibility as well as utilization of protein and energy in Kacang goats that were given Sorghum-Clitoria ternatea [PKSS-Ct] Silage-based Complete Feed. The study used an experimental method with a randomized block design [RBD] with four treatments and four replications, namely T0: Silage of sorghum – Clitoria ternatea without concentrate; T1: T0 + 10% concentrate with 150 mg ZnSO4 / kg DM ration and 2% Zn-Cu isoleucinate/kg DM concentrate; T2 : T0 + 20% concentrate with 150 mg ZnSO4/kg ration feed and 2% Zn-Cu isoleucinate/kg DM concentrate and T3: T0 + 30% concentrate with 150 mg ZnSO4/kg BK diet and 2% Zn-Cu isoleucinate/ kg BK concentrate. Parameters measured were 1]. Chemical composition of feed 2]. Rumen Fermentation of kacang goat. The results showed that the treatment had an effect on increasing the crude protein content and BETN, conversely there was a decrease in crude fiber content and a very significant increase in NH3 concentration and VFA production [P<0.01] and the highest increase was in T2. It can be concluded that complete feeding based on Clitoria ternatea sorghum silage with the addition of concentrate containing 150 mg ZnSO4/kg DM ration and 2% Zn-Cu isoleucinate/kg DM concentrate at a level of 20% can increase the concentration of NH3 and the highest VFA production in kacang goats.
