Effect of buffer addition to total mixed rations on feed intake, milk production and rumen fermentation in HF

The aim of the present study is to investigate the effect of CRB-advance as a dietary supplement on the rumen fermentation, micro biota and production performance (milk, fat &amp SNF). In dairy animal trials in India,buffers are the crucial for maintaining ruminal health and optimizing milk production by neutralizing excess rumen acidity and preventing ruminal acidosis.Total 40 animals early to mid-lactation Holstein were selected for 60 days’ study and divided in to two treatment groups. In both the group buffer was added separately to the total mixed ration (TMR) and fed at a rate of 100 gm per animal/day. Group 1 offered CRB- Advanced commercially available buffer along with TMR while group 2 treated with Sodium bicarbonate @100 gm/cow per day and 40 gm magnesium oxide per cow per day. Both the group were similar in milk production, and milk components.The result indicated that CRB-Advanced dietary supplementation stabilized rumen ph.,improved gut micro biota, richness and partially probiotic colonization and considerably increased dry matter intake, milk production, compare to the traditional buffer available in the market.
