Abstract Content | Use of coccidiostats in broiler feed will become increasingly restricted due to anticoccidial resistance, consumer objections and legislation. Cost-effectiveness of alternative interventions cannot be assessed by looking at individual birds, but is determined by effects on the course of infection in a flock. In broilers, timing of exposure to different doses of (vaccine of wild-type) oocysts and uniformity of oocyst uptake determine clinical outcome and economic losses. Therefore we focus on Eimeria infection dynamics by combining transmission experiments and mathematical models. |
