Rumen gas contains carbon dioxide and methane which are exhaled contributing to greenhouse gas (GHG) emissions. An in vitro rumen simulation model experiment was conducted to understand the role of common ingredient Murraya koenigii (Kadhi patta) (being used in indigenous veterinary system of medicine) as a feed additive to mitigate GHG emission. Goat ruminal contents were collected and experiment was conducted in two simulated rumen chambers viz., control (without medication) and test (with Murraya koenigii). Variables such as pH, rumen microflora and gas production were measured over an experimental duration of 4 hour(s). The coefficient of variability for pH was found to be less homogenous in test chamber (3.14%) than control (2.64%) during experimentation. Further, the percent change of total protozoan count was higher in test chamber (26.63%) than control chamber (21.73%). The nature of gas produced was found reduced in comparison to control chamber to an extent of 20.83 per cent. The study confirms that curry leaf (Murraya koenigii) can affect pH, rumen protozoa and reduce gas production in simulated rumen conditions.
