Appraisal of a new patented method for control of chicken coccidiosis

Abstract

The aim of this research is to appraise a newly patented method for control of chicken coccidiosis in comparison to a classical approach. The new method implements an invented Disinfectant (WSD) for decontamination of rearing surfaces, and a developed drinking water-herbal coccidiostat (EOBWE) supplement. The experimental design has 8 treatments (TRTs), with four pens/TRT, and 25 broiler chicks/pen. The floors of TRT1 to TRT7 are contaminated with 4.0 × 105 sporulated oocysts/m2 of each of E. acervulina, E. maxima, and E. tenella, while TRT8-floor is left uncontaminated. The floors of TRTs 1 and 2 are disinfected with chlorine, while that of TRTs 3–6 are disinfected by WSD. Floors of TRTs 7 and 8 are deprived of disinfection. Birds in TRTs 1, 6, 7, and 8 are deprived of coccidiostat, while birds in TRTs 2 and 3 are fed salinomycin in their feed; birds of TRT 4 are administered EOBWE in drinking water, while birds of TRT 5 are administered simultameously both, the salinomycin and EOBWE. Birds in TRT 4 (WSD/EOBWE treated) and TRT 5 (WSD/salinomycin + EOBWE) had improved protection (lowest oocyst output and intestinal lesions) and enhanced production (lowest mortality, lowest feed conversion ratio, and highest live body weight) compared to the other five challenged treatments, associated with significant improvements compared to positive controls (TRT 7) (P < 0.05).
