DETERMINATION NUTRIENT VALUE OF SOME COMMON FEED RAISING BUFFALOES BY IN VITRO GAS PRODUCTION METHOD

Abstract

The objective of this study was to determine the nutrient value of some common feed raising buffaloes by in vitro gas production method.  Two male buffaloes, 18 months of age, average body weight 234 kg were used to take the ruminal fluid. Four types of green forage and six types of dry forage were used to determine nutrient value by using the in vitro gas production method. The results of the study showed that green forage group had dry matter (DM) to range from15.52 to 25.58%, crude protein (CP) 6.75-12.14% and crude fiber (CF) 20.17-30.83%. The dry forage group had DM to range from 86.49 to 91.25%, CP 5.15-26.40% and CF 10.70-32.56%. The volume of gas production increased following the time of samples incubation in both green and dry forage groups and the different types of feed had different volume of gas production. The ability of gas production and rate of gas production in green and dry forage groups ranged from 42.80-52.87 ml and 0.03-0.04% hour and 31.56-58.20 ml and 0.02-0.05% hour. OMD in dry forage group to range from 32.46 to 40.97% was lower than that in green forage group to range from 53.28 to 60.35% except cassava leaves meal (61.83%). ME of some common feed ranged from 6.62 to10.73 MJ/kg DM.
