Zootechnical and economical evaluation of the use of a live anticoccidial vaccine in rotation with anticoccidial products in broiler chickens
Anticoccidial vaccination applied in problematic farms for coccidiosis, proved to improve productive performances and financial parameters, especially when returning to in-feed
anticoccidials: lower FCR and mortality, higher ADG final body weight and EPEF. In general, we can conclude that there were no statistical differences between pre- and inter-vaccination in any case.
In industrial poultry production, designing a preventive program for controlling coccidiosis is one of the most important decisions to be made in order to safeguard or improve zootechnical and financial results. Usually in-feed anticoccidials are used in these programs and traditionally were considered sufficient for controlling clinical coccidiosis. Live coccidiosis vaccines are becoming increasingly popular though, as they very often provide a solution when the in-feed anticoccidials become inefficient. In fact, live coccidiosis vaccines are able to promote the restoration of the sensitivity of Eimeria field strains towards anticoccidials.
