Use of in vitro gas production technique to evaluate the effects of microwave irradiation on sorghum (Sorghum bicolor) and wheat (Triticum sp.) nutritive values and fermentation characteristics
Effects of microwave irradiation (900 W) for 3, 5 and 7 min on the nutritive value of sorghum and wheat grains were evaluated by in vitro gas production technique. Gas volume was recorded at 2, 4, 6, 8, 12, 16, 24, 36, 48, 72 and 96 h of incubation and kinetics of gas production were estimated using...
