Effect of TMR and Fermented TMR on Ruminal In-vitro Digestion

Abstract

Ruminants are an essential part of livestock expert in converting cellulose and other fibrous materials into high quality milk & meat which depends on digestibility of feed. The study were conducted with new feeding strategies of different roughages and concentrate mixture with fermentation to increase digestibility. Total mixed ration (TMR) produced with 70% roughage of silage & rice straw and 30% concentrate mixture. Fermented TMR (FTMR) produced by mixing TMR feed with molasses containing Saccharomyces Cerevisiae. With this study, we evaluated the effects of TMR and fermented TMR feed on total gas production, pH, digestibility of ruminant by ruminal in-vitro digestion method. Data were collected for In-vitro digestion trial at 6hr, 12hr, 24hr & 48hrs of incubation period. We observed decreasing tendency of pH with the increasing incubation period and no significant difference between TMR & FTMR. Digestibility of FTMR was significantly higher than the TMR (P < 0.01). On the other hand, total gas production was significantly lower in FTMR than the TMR (P <0.01). So we can conclude that FTMR is better than TMR in terms of digestibility and gas production
