Setting the Record Straight on Vaccination Against Coccidiosis

chemical is the other better way except you raise without antibiotic

Thanks for an excellent article. What information do you have on use of such vaccines in countries of Middle East and Africa? Should we expect similar comparisons between vaccine and coccidiostats? Might there be strain-specific differences? Thanks MPS

How much time is required for the vaccine strains to replace the field strains of coccidia in the birds, will the composition of feed (added enzyme and probiotics) have its effect on the replacement process.

Congratulations to the authors for this very interesting comparison. It's important to realize, though, that comparing field results between different periods of the year (like in this case summer vs winter) is subject to potentially large error if there exists seasonality along the year. Exploring results from previous years allow to evaluate if this is an important factor to be accounted for.
