Evaluation of Management Treatments Intended to Increase Lamb Recruitment in a Bighorn Sheep Herd

We administered a suite of treatments to a herd of Rocky Mountain bighorn sheep (Ovis canadensis canadensis) that was experiencing poor lamb recruitment and showing signs of respiratory disease. Despite 3 yr of treatment with various combinations of anthelmentics, antibiotics, vaccines, and hyperimmune serum products, recruitment was not improved.
