A study led by Lancaster University has found that adopting high yield dairy cattle breeds and improving feed could help Tanzania increase milk production, reduce greenhouse gas emissions, and alleviate poverty. The research, published in Nature Food, suggests that by changing from local to improved breeds of cattle and feeding them more nutritious, locally produced feed, Tanzania could meet its climate commitments and self-sufficiency targets in milk production. The study also highlights the need for support policies to prevent a decrease in income for farmers who cannot invest in feed and care for higher yielding cattle.
