Influences of urea treated corncobs (UTC) ensiled with or without different additives on ruminal characteristics, in situ digestion kinetics, nutrient digestibility and nitrogen metabolism were examined in a Latin square design using five ruminally cannulated buffalo bulls. Five iso-caloric and iso-nitrogenous diets were formulated to contain 30% dry matter (DM) from concentrate and 70% DM from 5% UTC ensiled without any additive (U) or with 5% enzose (EN), 5% acidified molasses (AM), 5% non-acidified molasses (NM) and 5% acidified water (AW), respectively. These diets were fed to buffalo bulls at 1.5% of their body weight daily. Ruminal -N concentration at 3 hours (h) post feeding was significantly higher in bulls fed U, NM and AW diets, however, at 6, 9 and 12 h post feeding it was significantly higher in bulls fed EN and AM diets. Ruminal total volatile fatty acids (VFA) and acetate concentrations were significantly higher with EM and AM diets compared with other diets at 3, 6, 9 and 12 h post feeding. Ruminal pH at 6 and 9 h post feeding was higher with EN and AM diets; however; it was notably lower with these diets at 3 h post feeding. Total ruminal bacterial and cellulolytic bacterial counts were higher in bulls fed EN and AM diets than in those fed the other diets. In situ ruminal DM and NDF degradabilities and total tract digestibilities were significantly higher with UTC ensiled with enzose and acidified molasses than those ensiled without any additive or other additives. Nitrogen balance was significantly higher in bulls fed EN and AM diets than those fed U, AW and NM diets. The UTC ensiled with enzose or acidified molasses resulted in better digestibility and N utilization than those ensiled without any additive, with non-acidified molasses and acidified water in buffaloes.
