The Alberta Lamb Producers (ALP) is aware that producers have been struggling with having timely access to dewormers for their flocks, with options like Startect becoming unavailable in Canada. We are pleased to share that ALP was able to work with a Canadian Company whereby they were able to create a new compound that producers across Canada will have access to.
Sheep that are maintained on pasture commonly become infected with nematodes (roundworms) that live in their gastrointestinal tract. The three most important gastrointestinal nematodes (GINs) infecting sheep are Haemonchus (barber’s pole worm), Teladorsagia (brown stomach worm) and Trichostrongylus (stomach hairworm). The barber pole worm has been shown to be resistant to ivermectin in some Canadian flocks but has been shown to be sensitive to the anti-parasitic drug levamisole. To address this concern an ivermectin-levamisole drench formulation has been developed which is available through most large animal veterinary clinics through a prescription. This formulation should provide protection for both internal and external parasites.
