Effect of himalayan batisha strong supplementation on in vitro digestibility

Effect of supplementation of different levels of Himalayan Batisha Strong (HBS) powder at the rate of 12.5, 25, 37.5 and 50 mg/50 ml incubation media were tested on in vitro rumen digestibility of three substrates i.e. concentrate mixture (C), dry oat fodder (O) and a mixture of C and O in 40:60 ratio. The HBS powder had no effect on rumen pH, HBS at 50 mg/50 ml increased (P<0.05) total volatile fatty acids (TVFA) concentration, NH₃-N concentration, molar proportion of acetate and propionate and in vitro DM digestibility (IVDMD) but depressed (P<0.05) molar proportion of butyrate irrespective of substrate. Thus, HB-Strong powder supplementation at 50 mg/50 ml level seemed to have a stimulatory effect on rumen micro flora.
