Sirs, We are a poultry breeding farm. We got a little more than breeders in lay. The problem we face is mortality and no weight gain in our commercial broilers after 30 days due to CRD. We treat our breeder every month- Tiamutin 30mg/kg body wt and also vaccinate at 35 days after which we skip one treatment. I look forward to your valuable comments to counter this problem.
