摘要
672 milk flow curves of 30 cows from the milkings of one quarter and from the corresponding complete milkings of the respective following day were registered. With the aid of the ultrasound technique and an imaging analysis system the teat channel lengths, the teat wall thickness and the teat tissue areas were meseared before and after milking. The duration of decreasing flow rate of the complete milking can be explained by the traits of the milk flow curves of the quarter milkings. The maximum flow rate and the average flow rate were influenced by the shape traits of the teat apex.
