The present study was undertaken to analyze the influence of graded levels of niacin supplementation (0, 200, 400 and 600ppm, respectively) by in vitro gas production technique. The non-protein nitrogen sources were replaced by 30% of total crude protein of total mixed ration. It was found that true digestibility, organic matter digestibility and microbial mass production were significantly comparable in slow release urea and uromol based total mixed ration. Supplementation of niacin in urea (30%) based total mixed ration do not have any significant effect on microbial mass production and its efficiency. The in vitro ammonia concentration was significantly reduced at 600 ppm level of niacin supplementation. The total volatile fatty acid concentration was significantly higher at 200ppm level and lower at 400ppm level of niacin supplementation. Thus from the above study, it can be concluded that slow release urea give better result as compared to urea and uromol as non-protein nitrogen sources supplement in the diets of ruminants when replaced with 30% of total crude protein.
