Interesting question, though this is not my area of expertise, but amount of methane production by lactating cows depends upon nature of feed. Most of the studies reveal during first four lactating periods, methane production is maximum, thereafter it declines. Methane production per unit milk is also dependent upon the digestibility of feed .
