I have this 3/4yr old heffer, thats been acting strange & has lost weight. This started in the spring of 2003, she lost weight wasnt giving a lot of milk to her calf. So i wormed her, gave lepto & colostrium, plus pinicillin. She responded picked up weight did fine for the rest of the yr. This january she lost her calf, started loosing weight again & walking in circles.Then she wasnt eating like the rest of the cows ,so I vascinated again except give pinicillin. she still not gaining wht., walking in circles, & not eating like she should. I was reading and found this article on CIRCLING DISEASE/ LISTERIOSIS. and was wondering if this is what wrong with this cow.And if so what to do sell or keep.
