IN VITRO FERMENTABILITY,DEGRADABILITY AND MICROBIAL BIOMASS PRODUCT OF COMPLETE RATION CONTAINING A COMBINATION OF FIELD GRASS,CONCENTRATE AND NUTRIENT RICH SUPPLEMENT

Abstract

The objective of thi experiment wa to obtain an optimum combination between field gra , concentrate and Nutrient Rich Supplement (NRS)ba ed on in vitro tudy using Hohenheim ga te t.The experimental diet were:R1 (control diet =70%field gra +30%concentrate),R2 (70%field gra + 25%concentrate +5%NRS),R3 (70%field gra +20%concentrate +10%NRS)and R4 (70%field gra +15%concentrate +15%NRS).A randomized block de ign with four treatment and four replications wa carried out.Buffalo rumen fluid wa taken in different time and wa used a block or replication.Data were analyzed by Analysi of Variance (ANOVA).Significant difference among treatment were determined by contra t orthogonal.The re ult howed that total ga production and total VFA concentration were highe t (P<0.05)in R4 among the treatment .Addition of 15%NRS in complete ration (R4)increa ed NH3 concentration 10.34%.Addition of 10%NRS and 15%NRS in complete ration (R3 and R4)improved the microbial bioma product compared to control and 5%NRS in complete ration (R1 and R2).Dry matter (DM)and organic matter (OM)degradability were ignificantly higher (P<0.01)in 10%NRS and 5%NRS in complete ration (R3 and R2)compared to control and 15%NRS in complete ration (R1 and R4).It wa concluded that combination between 70% field gra ,20%concentrate and 10%NRS in complete ration (R3)wa more optimal for improving ga production,total VFA,NH3 concentration,microbial bioma product,dry matter degradability and organic matter degradability,compared to control ration.
