The present study was planned to evaluate the inclusion of graded level of formaldehyde treated dietary protein (rapeseed meal) for ruminant feeding through in vitro gas production technique. Five different type of concentrate mixtures were prepared by replacing protein ingredient (rapeseed meal) from basal concentrate mixture at graded level (0, 25, 50, 75 and 100%) with that of formaldehyde treated one. The respective diet prepared from these concentrate mixture were incubated with buffalo rumen liquor at ruminal temperature to assess the fermentation variables and nutrient utilization efficiency. The formaldehyde treatment of rapeseed meal resulted into improved production of microbial biomass with an enhanced tendency for its efficiency at the level of 50% and above. It has also prevented the microbial degradation of dietary protein as evident by lowering of ammonia nitrogen at dose level higher than 50%. The replacement of rapeseed meal with that of formaldehyde treated one in concentrate mixture have potential to protect the microbial degradation of protein in rumen with optimistic effect on microbial biomass production and rumen ammonia.
