In India, Cows Are Out and Buffalo Are In
Over 55% of the milk that Indians consume is now coming from buffalo, instead of the Indian Holy Cow. Over the past 40 years, there's been a dramatic shift away from using cows to till and fertilize farmland. They're being replaced with buffalo (who produce more milk), diesel-powered farm equipment, and chemical fertilizers.
The most obvious reason for that is milk. An average Murrah buffalo produces 2,000-odd litres over a 300-day lactation period, which is more or less what comparable elite indigenous cattle breeds such as Sahiwal yield. But buffalo milk also fetches higher price, as it contains 7-7.5 per cent fat – almost twice that from cows.
