Kecernaan in-Vitro Ransum Berbasis Limbah Jagung Amoniasi dengan Berbagai Rasio Konsentrat untuk Ruminansia

Abstract

The objective of this research was to determined the optimum ratio of ammoniated corn waste and concentrate in complete ruminant ration based on in-vitro digestibility. Four kinds of completed feed consisting of: R1=20% ammoniated corn waste and 80% concentrate, R2= 40% ammoniated corn waste and 60% concentrate, R3=60% ammoniated corn waste and 40% concentrate and R4=80% ammoniated corn waste and 20% concentrate. Digestibility was determined after 48 hours incubation with rumen fluid using Tilley and Terry technique (1969). Data were collected by a block randomized design. The measured parameters were the digestibility of dry materials, organic materials, crude protein and concentration of VFA and NH3 of rumen fluid. The result showed that digestibility of DM, OM, CP and concentration of VFA and NH3 has significantly effect (P<0.05). But there was not significant effect between R1 and R2 (P>0.05). In conclusion, a compound of 40% ammoniated corn waste and 60% concentrate was a better complete feed for ruminants ration.
