Mitigating Enteric Methane Emission from Livestock Through Farmer-Friendly Practices

  • C. Valli


Enteric methane emission in ruminants in addition to being an environmental pollutant causes a loss of 10–11% of the total gross energy intake of the animal. The various strategies available to mitigate enteric methane emission include management strategies, feeding strategies, rumen manipulation and advanced strategies. Feeding strategies are practical approaches to mitigate enteric methane emission and can be practiced with ease by farmers under field conditions. Various approaches that cause rumen manipulation and thereby reduce enteric methane emission are supplementation of bacteriocins, ionophores, fats, oils, organic acids, probiotics, prebiotics, sulphate, halogenated methane analogues, nitroxy compounds, fungal metabolite, secondary plant metabolites, microalgae and exogenous enzymes. In the Indian context, ruminant livestock are grazed in wastelands or fed with poor-quality agricultural waste, whose digestibility is low, and the nutritional requirement of the animals is not met resulting in poor productivity. Improving per animal productivity is a potent tool to reduce enteric methane emission per unit of product produced, and this can be achieved through ration balancing. As regards the greenhouse gas abatement opportunities, measures to reduce enteric methane production have immense economic and ecological benefits to the farmers.
