Pressure to maximize efficiency and lower inputs has resulted in novel approaches to managing and milking dairy herds, including implementation of automatic milking systems (AMS) to reduce labor associated with milking. Although AMS have been used for almost(More)
Facility design can affect the accessibility of an automatic milking system (AMS). In particular, gates and alleys positioned around the AMS may affect cow traffic and cow behavior, potentially affecting the duration of time the AMS is available for milking. Eighty-four Holstein cows of various parities and days in milk were randomly divided between 2(More)
Transitioning a dairy herd to an automatic milking system (AMS) from a conventional parlor system may be stressful for the cow, as many changes occur during this process. Chronic stress may affect the welfare of the cow, and acute stress during milking can decrease milk yield. Therefore, it is important to quantify if and how long stress during adaptation(More)
