Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Theses and Dissertations
Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …

Tactics For Identifying And Eliminating Tritrichomonas Foetus From Infected Beef Herds, Jeff D. Ondrak
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
The protozoan, Tritrichomonas foetus (TF), has been recognized as a cause of bovine infertility for more than 100 years (Skirrow and BonDurant, 1988). As an obligate parasite of the bovine reproductive tract its control and eradication seems achievable (Harding, 1950). However, this disease continues to trouble US cattle producers and a recent epidemic in the Western US has lead to increased interest in research and regulatory efforts (Cima, 2009).
Outbreak investigations were carried out on three Nebraska ranches to assess the efficiency of currently available diagnostic tests, culture, gel polymerase chain reaction (PCR), and real time PCR (rtPCR), in identifying …
