  • Research Projects
    Dr. Ayers is currently collaborating with Dr. Beth Mamer at the University of Idaho's Caine Veterinary Teaching Center concerning Johne's disease in sheep and goats. Dr. Ayers is looking at comparisons between testing methods and sample types. His goal is to find the most accurate and cost effective means of testing in sheep and goats that will allow the formulation of strategies for eliminating the disease from a flock or herd.

    Other areas of interest are bovine nutrition, reproduction, effects of drought on bovine performance, and passive transfer of colostral immunity.
