AT WHAT POINT SHOULD VACCINATED BIRDS BE TREATED FOR COCCI LESIONS?
A. There will be a percentage of birds (approximately 35%) with mild cocci lesions (+1 range) that should not be treated. This is normal and is needed to allow for proper cycling of the oocysts and ultimate immunity development in the birds. Typically, if there is a noticeable amount of cecal cocci (E. tenella), then treatment may be warranted usually amprolium at half level for 2 days.
