摘要: Feeding during milking has been observed to increase milk yield and flow, decrease time. High take off levels compared low levels, measured as g/min at the end of also reported flow. However it is not known how a combination two routines influences parameters yield, time The hypothesis tested was that feeding high flow time, producing higher efficiency. A crossover study design used with four treatments, groups, periods. treatments were level 800 + milking, no feeding, 200 g feeding. All cows got all treatments. experiment lasted for weeks each period one week. 32 Swedish Red belonging same barn participated in experiment. Parlor data captured, summarized, analyzed from 2322 separate sessions. There statistical difference between yield. significantly lower when used, reduced 51.3 seconds average per cow milking. increased level. did affect or level, while tendency shorter fed concentrate There effect on udder emptying due treatment. In conclusion automatic cluster removal offers an important potential opportunity parlor efficiency commercial dairy herds.
