Abstract

The present investigation was carried out to determine the nutrient composition and degradation kinetics of two locally available legume straws viz. red gram and black gram by using Nylon bag technique. The CP, NDF and ADF content in red gram and black gram straw were found to be 6.76 and 7.70, 75.80 and 69.20, 58.6 and 54.9 per cent, respectively. Three rumen fistulated male Murrah buffalo bulls (5 yrs old mean body weight of 350 ± 9.36 kg) were used to study the in situ degradation kinetics of DM, CP, NDF and ADF in selected straws. The mean value of the per cent effective degradability (ED) of DM and ADF calculated from the rumen out flow rates (0.05 % h-, as average) were higher (P<0.01) in black gram straw (29.03 and 23.67) than in red gram straw (25.57 and 19.33), respectively. However, the effective degradability (%) of CP and NDF (0.05 % h-, as average) were higher in black gram straw, but the differences were not statistically significant. It is concluded that legume straws are good feed resources for ruminants and can help to correct fibre shortage and black gram straw proved to be better utilized compared to red gram straw.
