A Qualitative Research Approach To Understanding Challenges That May Inhibit Optimal Usage Of Automatic Milking Systems In Northern Utah, Jessica Christensen
A Qualitative Research Approach To Understanding Challenges That May Inhibit Optimal Usage Of Automatic Milking Systems In Northern Utah, Jessica Christensen
Undergraduate Honors Capstone Projects
Dairy robotics, i.e., Automatic Milking Systems (AMS), is a relatively new field, one that has great promise to optimize efficiency, production, and animal welfare of dairy cattle. However, despite quantitative research findings that indicate AMS success, dairy farmers still face challenges integrating AMS into their production systems. During the fall of 2018, interviews were conducted with northern Utah dairy farmers regarding their robotic systems. The respondent data was analyzed to reveal repeated problems with the robots. This analysis was then used to direct research in order to propose solutions to the farmers' AMS challenges. Conclusions were then summarized in an …
Dairy Herd - Level Prevalence Of Johne's Disease And Bvd In The Intermountain West Of The U.S.A. And Farm Management Practices And Characteristics For Test-Positive Herds, David J. Wilson, Kerry A. Rood, C. Whitehouse, J. Bunnell, G. M. Goodell, T. M. Byrem

Herd-level prevalence of Mycobacterium avium subsp. paratuberculosis (MAP), causative agent of Johne’s disease (JD) and Bovine Viral Diarrhea (BVD) virus were estimated on dairy farms in Utah. Duplicate milks were collected at 3-4 day intervals on 5 dates from each bulk tank on participating farms. Samples were tested at separate laboratories for BVD (real-time, RT-PCR) and for JD/MAP (ELISA and qPCR). 151/209 (72%) eligible dairy farms participated. Farms detected positive were: 58 JD (38%) and 14 BVD (9%); 5 farms had both diseases. Follow up visited farms’ (n=22) means, medians: 778,420 milking cows; 20,052 lbs, 20,311 lbs 305d milk; 175,545/ml, …
Johne's Disease, Mycoplasma And Bvd In Utah - Bulk Tank Milk Testing And Comparison To Previous Regional Prevalence And Individual Herd Results Over Time, David J. Wilson, Kerry A. Rood, J. Bunnell, C. Whitehouse, G. M. Goodell, T. M. Byrem

Animal, Dairy, and Veterinary Science Faculty Publications
Dairy herd-level prevalence of Mycobacterium avium subsp. paratuberculosis (MAP), causative agent of Johne’s disease (JD), Mycoplasma spp., and Bovine Viral Diarrhea (BVD) virus were estimated in Utah and surrounding states and compared to previous surveillance results. Milk was collected at 3-4 day intervals on 5 dates (duplicate samples) from each bulk tank on participating farms, samples analyzed separately. One frozen sample was shipped to a laboratory for JD/MAP testing with ELISA and real-time PCR, the other paired sample was shipped to another laboratory for mycoplasma and BVD testing. Mycoplasma was cultured on modified Hayflick medium, standard methods; BVD testing was …
