Reducing carbon emissions in animal agriculture requires innovative strategies. Utilizing predigested feed or feed additives like tannins and saponins enhances nutrient absorption, inhibits methane production, and optimizes feed efficiency. Feeding animals mango leaves, rich in methane-inhibiting compounds, offers a sustainable, locally available feed source, potentially reducing enteric fermentation emissions. Incorporating oil into animal diets increases energy density, improves digestibility, and inhibits methane production, promoting balanced nutrition and sustainable resource use. Feeding concentrates ensures optimal nutrient utilization, reduces enteric fermentation, and improves feed conversion efficiency. These approaches offer multifaceted solutions to mitigate carbon emissions in animal agriculture, advancing sustainability and environmental stewardship.
