Introduction There are concerns that antimicrobial usage (AMU) is driving an increase in multi-drug resistant (MDR) bacteria so treatment of microbial infections is becoming harder in humans and animals. The aim of this study was to evaluate factors, including usage, that affect antimicrobial resistance (AMR) on farm over time. Methods A population...

The survival of foot-and-mouth disease virus (FMDV) in the environment provides an opportunity for indirect transmission, both within and between farms. However it also presents the possibility of surveillance and detection via environmental sampling. This study assesses the effectiveness of environmental sampling strategies in the event of an outb...

Bladder tumors of cattle are very uncommon accounting from 0.1% to 0.01% of all bovine malignancies. Bladder tumors are common in cattle grazing on bracken fern-infested pasturelands. Bovine papillomaviruses have a crucial role in tumors of bovine urinary bladder. To investigate the potential association of ovine papillomavirus (OaPV) infection wit...

Livestock removal is increasingly used as a management option to mitigate the negative impacts of grazing-related disturbances on rangelands. Removal generally increases plant cover, but it is unclear when, where, and by how much plant and soil cover changes can be expected. On the Colorado Plateau, complex geology, topography, soils, and climate a...

Introduction On-farm biosecurity is an essential component of successful disease management in the beef cattle industry on an individual, regional, and national level. Participation in mandatory or voluntary assurance schemes, knowledge and trusted relationships have all been demonstrated to contribute to the development of behaviors that promote b...

Genomska selekcija je postala rutinska metoda pri mlečnih pasmah govedi. Z uvedbo genomske selekcije generacijski interval vsaj prepolovimo, kljub manjši točnosti plemenskih vrednosti, se genetski napredek poveča. Tako hitreje pridemo do želenih rezultatov posameznih živali, črede in populacije. Nadziramo lahko tudi širjenje dednih napak in prepreč...

Z našo raziskavo smo želeli opredeliti varen odmerek UV sevanja za sintezo vitamina D pri kravah molznicah črno-bele pasme in preveriti uporabnost obsevanja z UVB lučjo ozkega spektra, omejenega na čas robotske molže za sintezo vitamina D. Ugotoviti smo skušali tudi vpliv dolžine dlake in barve kože oziroma dlake na sintezo vitamina D pri govedu. V...

Bovine brucellosis is a bacterial zoonoses caused by Brucella abortus. We conducted a cross-sectional study to determine brucellosis seroprevalence and risk factors among smallholder dairy cattle across six regions in Tanzania. We sampled 2048 dairy cattle on 1374 farms between July 2019 and October 2020. Sera were tested for the presence of anti-B...

Introduction Neospora caninum and Toxoplasma gondii are closely related obligate intracellular protozoan parasites. They are considered to be the major causes of infectious abortions and congenital abnormalities in livestock worldwide resulting in huge economic losses. Currently, there are no reports on the prevalence of neosporosis or toxoplasmosi...
