When the time of birth comes near, the mammary gland (udder) starts swelling and also releases some milk, the belly starts bloating. It is necessary to provide suitable place to give birth. Horse stall is the best place for this purpose provided with fresh water, grass and hay. When the labor pains begin, the mare seems restless and after so many struggles of getting up again and again she will finally give birth to a young one.
