HOW SHOULD COCCIVAC VACCINATED FLOCKS BE MONITORED AFTER VACCINATION?
A. A representative number of Coccivac vaccinates should be monitored by postmortem examination when the first vaccinated flocks reach 21 days of age. Vaccinates should demonstrate coccidial lesions within the expected vaccination profile. A representative number of Coccivac vaccinates should again be monitored by post-mortem exam when the first vaccinated flocks reach 28 days of age. Vaccinates should demonstrate resolution of coccidial lesions within the expected vaccination profile. Vaccinates 7 through 21 days of age should also be observed in the field for signs of necrotic enteritis or management practices that are incompatible with controlled vaccine cycling. Thereafter, flocks should be monitored by monthly postmortem sessions including representatives from 14 days of age through slaughter, with an emphasis on ages 21 through 35 days. Q.
