Gastrointestinal nematode infections are the most pervasive problem currently facing the small ruminant production. The situation of anthelmintic resistance in sheep and goat farms has exceeded the control capacity of U.S. producers. In addition to technical support schemes for diagnostic, it is important to implement genetic selection programs to identify superior resistant animals to gastrointestinal nematode infections and reduce the dependence on anthelmintic treatment. Unless these strategies are implemented for producers, the negative effects of anthelmintic resistance on small ruminant farming in U.S. will continue to be detrimental.
Our research group focuses on identifying genetic markers for a sustainable and practical management systems in sheep and goat population, including the Florida Native sheep populations, to control gastrointestinal nematode infections.
