How do you get a 2 day old calf to nurse?

First tie up the mother cow or serrogate mother in a stall or have her in a chute were you can easily access the udder. Hobble her in case she decides to kick. Next, guide the calf to the cow's udder and see if it will try to latch on. If not, open the calf's mouth and at the same time squirt some milk into the calf's mouth to get it to have a taste of it. You may have to put the teat into the calf's mouth and help it suckle by doing the similar thing mentioned previously. If it can't suckle enough to get adequate nutrients (first day after birth is vital the calf gets its colostrum), you will have to tube it orally. It is VERY important that the calf gets its colostrum after birth, otherwise its chances of surviving are very slim, even if the calf is 2 days old. But don't quit, get some electrolytes in it, and powdered colostrum (mixed with water of course.) Good luck!
