I bought a calf yesterday from the sale barn and I can't get her to suck the bottle. I believe she has been on her momma up till yesterday and she shows no interest in bottle feeding. I tried squeezing the nipple in her mouth and she will swallow, but not suck herself. She isn't weak, doesn't have any trouble breathing and she looks good. She is about 70 lbs. She is probably a month old I would think. I bought her Land O Lakes milk but I tried to feed her this special double medicated milk the guy at the Coop said she needed for her first day. Could it have had so much medication in it that it tasted so bad she wouldn't eat it? Also, when I stopped trying to feed her, she lowered her head and strarted eating straw. I have never had any trouble getting calves to take a bottle. Any suggestions?
