Abstract:
The super napier silage, CoFS 29 silage, tur pods and concentrate feed mixture (CFM) procured and subjected for chemical analysis. Estimated proximate composition of silage was within the range when compared to other grass silages variety. The in vitro gas production and predicted metabolizable energy for 24 hours is higher in CFM and lower in tur pods. Among the silages, CoFS 29 silage had higher in vitro gas production and predicted metabolizable energy for 24 hours. The t½ was lower in CoFS 29 silage when compared to super napier silage. The partitioning factor, microbial biomass production, efficiency of microbial biomass synthesis were higher in CoFS 29 silage when compared to super napier silage and tur pods. Hence, CoFS 29 silage can be used as a good quality roughage source over Super napier silage and Tur pods due to improved truly digestible organic matter, energy value, partitioning factor and microbial biomass synthesis.
