Hi, we have a calf that just won't get better we've had the vet out. We vaccinated this calf and we have giving him Baytril and Nuflor. He seemed to get better after around of Baytril, but a few days later he's back to were he was. He breaths short and hard, somedays he has mucus coming out of his nostrils (not as white as it was). The vet doesn't seem to sure of what wrong. I'm going to hopefully talk to him today. I found this forum in my search for help, any would be appreciated. My husband and I are both pretty new to cattle, he's raised some in the past. Thanks Rainy
