i bought a cow from the sale barn about 2 months ago. she was kind of poor with a 250# calf, i thought she just needed a better home. after getting her home i decided to pull the calf off so she could gain some weight. i have shot her several times with la-200. her nose will quit running for about 3 or 4 days but will start up again after that. i am giving her 12-percent feed with plenty of green grass and keeping her isolated from the other cows. i have also given her a shot of b-complex. anyone have any ideas. she is also not gaining any weight.
