Wabi, how come you got cows with scours?
I dont remember having a cow with scours, calves yes! In fact, I use to give every calf a pill. If they didn't have scours, they was gonna get it. Giving every calf the pill, when it was a day or two old, save me a lot of headaches. Teramycin sp? I think, but not sure.
Glad your system worked out. That's a lot of cow in a short time.
