Abstract:

The main objective of the present study was to investigate the effect of incorporation of graded levels of RDDGS in the concentrate mixtures on in vitro nutrient digestibility and rumen fermentation pattern using buffalo inoculum. Soybean meal (SBM) based conventional concentrate mixture was prepared and SBM in the concentrate mixture was replaced by RDDG at graded levels of 25, 50, 75 and 100 per cent on N basis. The nutritional worth of various concentrate mixtures was assessed by in vitro gas production technique. The in vitro study of concentrates containing graded levels of RDDGS revealed that OM, NDF and DM digestibility increased (P<0.05) with the increasing level of RDDGS in the concentrate mixture. The MMP of concentrate mixtures increased (P>0.05) with increasing levels of RDDGS replacing soybean meal. However, the increase in MMP was statistically non-significant. The ME availability was highest (P<0.05) in concentrate mixtures containing 50 and 75% RDDGS replacing soybean meal. The ammonical-N of the concentrate mixtures decreased (P<0.05) with the increase in the inclusion of graded levels of RDDGS in concentrate mixtures replacing SBM. The acetic acid content and A:P (mM/dl) ratio decreased(P<0.05) with increasing level of RDDGS replacing SBM in the concentrate mixtures. The inclusion of graded levels of RDDGS in the concentrate mixture was observed to have no significant effect on the methane production in concentrate mixtures. Hence, it was concluded that RDDGS could be considered as promising protein supplement for livestock and can replace conventional oilseed cakes viz., soybean meal upto 75 % in the concentrate mixture without any adverse effect on nutrient digestibility, ME availability, fermentation efficiency and methane production.
