Abstract Toltrazuril (Baycox�) stand-alone treatment and Paracox-5 (live attenuated vaccine) were assessed in a field trial for broiler coccidiosis control. The feed did not contain coccidiostats or antimicrobial performance enhancers. Fifteen farms encompassing 90 flocks were followed over three trial episodes (Vaccination-1, Toltrazuril and Vaccination-2). Each episode included two successive flocks/growouts. Daily weight gain, feed conversion ratio, production number and mortality rate were assessed as performance parameters, indicative of coccidiosis control. No cases of clinical coccidiosis were diagnosed during the course of the trial. In general, there was a wide variability in production number within most of the farms, with only a few showing a more consistent performance. Although descriptive statistics showed small differences between the treatments, an analysis of covariance revealed no significant (P [ABSTRACT FROM AUTHOR] |
