Breeder layer RPs are frequently reared on Denagard-compatible anticoccidials or more recently coccidiosis vaccines, as producers want the birds to be immune by the time they reach the laying period. In this case the birds may be given the complete programme especially if they are coming from infected stock or are at high risk, in a mycoplasma endemic area, from contacting the infection during the rearing period.

Programme B – birds on monensin during the rearing period
Pullets may be given the anticoccidial monensin, which is incompatible with Denagard, upto 16 weeks of age. In this case Denagard cannot be used until at least 7 days after monensin has been withdrawn from the feed (week 17). In this case, Denagard can be administered from 17 weeks of age either to clean up the flock or to initiate a prevention programme and again at 20 weeks of age at placement.

Denagard can be continued into the laying period in a regular programme to utilise its protective activity on the hen, egg and chick.
