The system dynamics of a milking machine vacuum system were analyzed. The effects of vacuum pump capacity, reserve tank, and pipeline sizes were examined using a mathematical model and dynamic system analysis techniques. A large vacuum pump can reduc

Vacuum, air temperature, and airflow in a pipeline milking system are measured at various locations to obtain systemwide data on dynamic variations. High frequency variations caused by vacuum pump operation are attenuated, and slight damping exists.

The rate of calf mortality increases with increasing herd size unless a specialist is involved in calf raising; then there is a drop in the death rate. Breeds of larger dairy cattle have more difficulty calving, and this appears to result in a high c

Milk production per cow often declines following expansion of a dairy herd. In this study of 192 Minnesota herds, loss of production depended on the change in housing system and herd management during and immediately after expansion. Four housing swi

DAIRY cow behavioral responses to alternating and direct current were examined for three body pathways: mouth-to-all hooves, front-to-rear hooves and body-to-all hooves. For mouth-to-all hooves and front-to-rear hooves pathways, response frequency fu

ELECTRICAL resistance data were collected for eight pathways through dairy cows. Significant variation in resistance was found between pathways through individual cows and between cows. The mean path resistances ranged from 359 ohms for a mouth-all h

THE electrical resistance of two components of a milking system were measured for configurations simulating both high and low milk pipelines. Resistance of the milk hose from the milk receiver to the machine claw during milking was found to be invers
