Johne’s Disease is a chronic wasting disease in cattle and other ruminants caused by a bacterium. Due to the long incubation period of the disease, it can take several years for a farmer to realize their dairy animals are infected. General clinical signs include: Weight loss, low milk production, decreased fertility, diarrhea and even death. Excessive culling and financial loss often occur in herds infected with Johne’s Disease. Several years ago, data was collected from a grant-funded research project on the impact of Johne’s Disease and dairy cattle. The first goal of this project is to analyze existing data, complete a statistical analysis and summarize findings. The final goal is to submit findings for publication. This research will be conducted in collaboration with Steven Kelm, professor of animal and food science.
