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 …

Context. Feral pigs represent a significant threat to agriculture and ecosystems and are disease reservoirs for pathogens affecting humans, livestock and other wildlife. Information on the behavioural ecology of feral pigs might increase the efficiency and effectiveness of management strategies.
Aims. We assessed the frequency of promiscuous mating in relation to oestrous synchrony in feral pigs from southern Texas, USA, an agroecosystem with a widespread and well established population of feral pigs. An association between multiple paternity of single litters and synchrony of oestrous may indicate alternative mating strategies, such as mateguarding.
Methods. We collected gravid sows at …
