NDRI scientists have injected non-pregnant and dry animals with progesterone and estrogen, the hormones that control milk production during pregnancy. Exotic cows usually respond well to injections of progesterone and estrogen in a 1: 5 ratio.
Do cows produce milk even if they are not pregnant?
Like humans, cows produce milk only after giving birth. Dairy cows must give birth to one calf a year in order to continue producing milk. Usually, artificial insemination is performed within 3 months after delivery.
