Ruminant methane mitigation- strategy from bench top to field condition: A review

Economical, eco-friendly, future ready and sustainable livestock production to meet ever growing human population is a daunting task for the animal farming community including scientist. Additionally making a sustainable effort to develop strategies or chain of strategies to combact global warming through manipulating ruminants farming is another growing challenge in the era of alarming global warming situation. Among the causes of global warming, animals particularly ruminants are one of the major contributor of methane. Strategies needed to be developed and implemented in order to rescue earth and its inhabitant from monstrous effect of global warming. Ruminant methane emission is one of the prime factor and steps needed to develop and invention of tools for reducing methane emission from enteric methane production which serves necessary evil of ruminants. Present review aims to explore the advancement achieved in rumen methanogen mitigation methods including its challenges and future prospective in order to make strategy implemented from present bench top to ultimate success in field condition.
