The older man I help out alot has a cow that is about 7 months bred. Anyway, she is limping on her back left foot, we got her up last Wednesday and pulled the foot up and it looks totally normal and good in between toes and all. He wanted me to give her some LA 200 so I did (it's his cow). She wa better for about 5 days and now limping again. She raises a great calf and breeds back fast so he wants to keep her if he can. Any ideas? Maybe she just stepped on something the wrong way?
