BACKGROUND The purpose of this study was to determine the prevalence of carpal tunnel syndrome (CTS) among dairy workers. METHODS Sixty-six dairy parlor workers and 58 non-parlor workers at dairies in Texas, New Mexico, and Colorado participated in structured interviews regarding demographics, work history, and hand symptoms. All participants had nerve conduction studies performed on both han...

Oxytocin can attenuate the physiological and behavioral response to stress in animals. In this study we investigated the relationship between plasma oxytocin concentrations and the behavioral and physiological response of dairy cows to a repeated psychological stressor (novel environment). Twenty lactating multi-parous dairy cows were milked in a familiar milking parlor and in a novel environme...

In conventional milking systems, dairy cows are driven to the milking stall twice or thrice daily, whereas in automatic milking systems (AMS), the cows enter the milking stall voluntarily. In this study, noninvasive methods were used to analyze the physiological reaction of 17 cows toward the changeover from conventional to automatic milking. Milk yield and composition were analyzed. Heart rate...

This paper uses Monte Carlo simulation methods to estimate the breakeven value for a robotic milking system (RMS) on a dairy farm in the United States. The breakeven value indicates the maximum amount that could be paid for the robots given the costs of alternative milking equipment and other important factors (e.g., milk yields, prices, length of useful life of technologies). The analysis simu...

For a long period of time, two person zero-sum games have been in the focus of researchers of various communities. The efforts were mainly driven by the fascination of special competitions like Deep Blue vs. Kasparov, and of the beauty of parlor games like Checkers, Backgammon, Othello and Go. Multi-player games, however, have been inspected by far less, and although literature of game theory f...
