Dairy Cow Welfare in Automatic Milking Systems
INTRODUCTION With any housing or feeding system employed for dairy cattle, careful consideration should be made to both the individual’s and herd’s well-being. Providing optimal welfare for dairy cows is a multifaceted and challenging task. Factors such as good herd management, adequate barn environment, automated milking system (AMS) management, social dynamics of the herd, and human-animal in...

15 صفحه اولOn the analysis of Canadian Holstein dairy cow lactation curves using standard growth functions.
Six classical growth functions (monomolecular, Schumacher, Gompertz, logistic, Richards, and Morgan) were fitted to individual and average (by parity) cumulative milk production curves of Canadian Holstein dairy cows. The data analyzed consisted of approximately 91,000 daily milk yield records corresponding to 122 first, 99 second, and 92 third parity individual lactation curves. The functions ...
متن کاملDifferences in Voluntary Cow Traffic between Holstein and Illawarra Breeds of Dairy Cattle in a Pasture-based Automatic Milking System
Automatic milking systems (AMS) rely upon voluntary cow traffic (the voluntary movement of cattle around a farm) for milk harvesting and feed consumption. Previous research on conventional milking systems has shown differences between dairy cow breeds for intake and milk production, however, the ability to manipulate voluntary cow traffic and milking frequency on AMS farms through breed selecti...
متن کاملInteraction between dairy cow physiology and milking technology
Anatomical and functional characteristics of the teat are supposed to have considerableinfluence on milk flow performance. In the present study various teat and milkingcharacteristics in 148 quarters of 38 cows were analyzed via 3 different approaches. Teatcanal length, teat wall thickness and teat diameter were measured by ultrasound. In addition,the vacuum needed to open the t...
