Abstract:

The present study was conducted to assess the chemical composition and in vitro nutritional worth of concentrate mixtures containing graded levels of cottonseed meal (CSM) at 0, 3.75, 7.50, 11.25 and 15% replacing SBM @ 0, 25, 50, 75 and 100% on w/w basis replacing soybean meal (SBM) in buffalo inoculum. Crude protein content of concentrate mixtures varied from 20.07% to 20.95%. Ether extract content in concentrate mixtures varied from 5.26% to 5.64%. No significant difference was observed in net gas production, partitioning factor, OM digestibility, NDF digestibility, microbial mass production, efficiency of microbial mass production, short chain fatty acids and metabolizable energy among the concentrate mixtures. The ammoniacal nitrogen (NH3-N, mg/dl) was higher (P<0.05) in concentrate mixture 1 (34.00) and lower (P<0.05) in concentrate mixture 5 (27.00) than other concentrates evaluated. The total volatile fatty acid production, hydrogen recovery and hydrogen consumed via CH4 was similar among the concentrate mixtures evaluated. No significant difference was observed in VFA utilization index among the concentrate mixtures. It was concluded that soybean meal could be replaced by CSM up to 100% in the diet of ruminants without affecting the nutrient digestibility and microbial mass production.
