The main objective of the present study was to investigate the effect of incorporation of graded levels of dried sugarbeet pulp in the concentrate mixtures on in vitronutrient digestibility and rumen fermentation pattern using goat inoculum. Maize grain based conventional concentrate mixture was prepared and maize grains in the concentrate mixture were replaced by dried sugar beet pulp at graded levels of 20, 40, 60, 80 and 100 per cent. 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 DSBP revealed that net gas production, OM digestibility, NDF digestibility, DM digestibility and ME availability increased (P<0.05) with the increasing level of DSBP in the concentrate mixture. Microbial mass production in concentrate mixture 2 (20% DSBP), concentrate mixture 3 (40% DSBP), concentrate mixture 4 (60% DSBP) and concentrate mixture 5 (80% DSBP) was similar to that of control concentrate mixture 1 (0% DSBP). The in vitro acetic acid production increased (P<0.05) and propionic acid decreased (P<0.05) with increasing level of DSBP replacing maize grains in concentrate mixtures. The TVFA production and A:P ratio increased (P<0.05) with increasing level of DSBP in the concentrate mixtures. The methane production was highest (P<0.05) in concentrate 6 when maize grains were completely replaced with DSBP. Hence, it was concluded that dried sugar beet pulp could be considered as promising energy supplement for livestock and can replace conventional cereal grains viz., maize upto 80 % on w/w basis in the concentrate mixture without any adverse effect on nutrient digestibility, fermentation parameters and methane production.
