Controlling spatial positioning of cattle through use of electronic collars could provide new ways to farm under extensive conditions. This study examined the potential for bulls to be controlled during mating using mild electric shocks delivered through radio-controlled collars. Eighteen Belmont Red bulls were fitted with collars containing the Global Positioning System and that were able to e...

The objective of this study was to determine the effects of enhancing cow subprimals on tenderness, palatability, and retail caselife compared with nonenhanced cow and USDA Select subprimals. Strip loin, top sirloin butt, and ribeye subprimals were selected (n = 60 per subprimal; n = 40 cow, n = 20 USDA Select). At 14 d postmortem, one-half of the cow product was randomly selected for enhanceme...

Economic decisions on animal health strategies address the cost-benefit aspect along with animal welfare and public health concerns. Decision tree analysis at an individual cow level highlighted that there is little economic difference between the use of either dry cow antibiotic or an internal teat sealant in preventing a new intramammary infection in a cow free of infection in all quarters of...

Although there is a general understanding that there is a link between poor cow comfort and lameness, the mechanisms by which one leads to the other are poorly understood. The objective of this article is to review the environmental impacts on hoof health in the dairy cow, describing the potential interactions between cow comfort and the trigger factors which ensure cows ‘get lame’ and the subs...

The anatomic variation of Circle of Willis (CoW) has great impact on its compensatory capacity during stroke and cerebral ischemia. In the present study, a series of lumped parameter models were developed and used to simulate the effect of postural changes on the cerebral blood flow in ICA stenosis patients with different anatomic variants of the CoW. The results showed that the asymmetric dist...

Cow size has been suggested to be an important consideration for selecting cattle to match their production environment. Over the last several decades, the trend in genetic selection for maximum growth has led to gradual increases in beef cow size. An unrelated trend during this same period in the western United States has been an increase in temperature, drought frequency, and drought severity...
