Influence of Different Plant Oils Supplementations on In Vitro Gas and Methane Production
This study was conducted to determine the effect of locally available Plant oils (garlic oil, Soybean oil and groundnut oil) on gas and methane production using in vitro gas production technique. There were four (4) dietary treatments; Treatment 1 was the control with no oil while 2, 3 and 4 each contained 30 ml/kg of garlic, Soybean and groundnut oils, respectively. Gas samples were measured at 3, 6, 12 and 24 hours of incubation. The in vitro dry matter digestibility and methane production were determined after 24 hours of incubation. The results showed that in vitro gas Production at different periods were significantly (P<0.05 )different between treatment groups at 12 and 24 hours of incubation for total gas production as well as methane and rumen pH while no significant difference was observed at 3 and 6 hours for rate of gas production and in vitro dry matter digestibility. This study showed that groundnut oil in the diet of ruminants reduced total gas production better than garlic and soybean oil. Thus, groundnut oil gave better performance and could be recommended as a better supplement in in vitro gas production because it lowered gas and methane production.
