Dr Kotaiah Talapanen, sadly the cocci vaccine is not foolproof with the current vaccines. A lot of management is necessary.

oumed gerjisVaccinate them at the hatchery. Manage the farm. Revaccinate if needed.

oumed gerjis Why you are vaccinating at day 4 vs day 1?

~25-35%

You can read my articles about coccidiosis in engormix (Coccidiosis control in broiler breeders with the use of vaccines: part one) or in www.aviagen.com

Arkan Lubani I did a study with revaccination at day 4 via spray in the brooding area after vaccination at day of age. so far many flocks with no coccidiosis in the field. I presented that work at AAAP 2021

Bouayad If cocci breakage persists, first check to see if the vaccine is viable. If it is, make sure the chick density is right to increase the humidity of the litter. I like about 40 chicks per m2 for the first 7-9 days. This can vary depending on the humidity of the litter. If the second cycle occurs correctly, you will have a decent number of oocysts per gram of feces and a good immune res ...

Dr Kotaiah Talapaneni. many reasons why the vaccine did not work. always check application and viability of the vaccine. but also field conditions. vaccine application can be fine but if field conditions does not work then breaks will occur. you may need to be more specific.

Dr Kotaiah, you may need to treat if you have a break, but need to look at brooding conditions besides the vaccine being applied properly
