Eight varieties of bajra stovers such as Jakarana, ICMV-221 (1H), ICMV 155 (1H), Wrajpop, Sosat C88, ICMV 221 (2H), ICMV 155 (2H) and Sadore local and two varieties of sorghum (PKV 801-1 and PKV 801-4) and cowpea hay (C-151) grown in ICRISAT, Patancheru were evaluated for their in vitro gas production (IVGP). Fresh fecal inoculum (FI) with nitrogen supplemented (N+) and unsupplemented (N-) incubation medium was used as a source of incubation to replace the rumen inoculum on microbial nitrogen equivalent to describe volume of in vitro gas production of stovers. Chemical composition of stovers evaluated was 3.00 to 6.51 for CP, 0.80 to 1.53 for EE, 26.05 to 40.53 for CF, 8.77 to 14.04 for TA, 43.57 to 57.53 for NFE on DM basis. Significantly (P<0.05) highest gas production was noticed in ICMV 221 (1H) variety of stover in both N+ and N- medium of FI. It is concluded that the gas production parameters of stovers and cowpea hay incubated with FI with or without nitrogen supplementation could be used as a primary tool and basis for screening and selecting the stovers for feeding ruminants.
