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. | Influence of graded levels of niacin on in vitro digestibility of total mixed ration with different non-protein sources
