If you are planning to pasture your flock, it is a good time to review your parasite control program. Several research projects have been conducted in Ontario over the past 4 years in order to understand the effect of lambing season on the periparturient egg rise, the overwintering survival of gastrointestinal on Ontario pastures and to determine the level of anthelmintic resistance in Ontario sheep flocks.
