Sažetak
The paper deals with the changes of some parameters of dairy cows teat caused by machine milking. Ultrasonographic scanner GE Medical Systems LOGIQ 100 PRO with linear array VE 5 with 5 MHz probe was used for scanning the teats. Scanning was conducted on nineteen cows of Holstein-friesian breed. The cows were housed in a free stall barn and milked in a herringbone milking parlour 2x3 with Alfa-Laval milking system with Duovac milking units. Teat scanning was done just before morning milking and immediately after milking on the right side of the udders for front and rear teats. The following parameters were measured: teat canal length (TCL), teat end width (TEW), teat cistern width (TCW) and teat wall thickness (TWT). Ratio between teat wall thickness and teat cistern width (TWT/TCW) before and after milking was calculated. Length of teat canal for the front right teat increased in average for 12.55% after milking and 23.61% for the rear right teat. Teat end width of the front and rear right teat increased after milking for 1.25% and 4.79%, respectively. Mean teat cistern width of the front right teat decreased after milking for 22.27%, while for the rear right teat mean decrease was 25.63%. Teat wall thickness of the front and rear right teat increased after milking for 5.22% and 17.26% respectively. Ratio between teat wall thickness and teat cistern width (TWT/TCW) changed from 0.635 before milking to 0.860 after milking for the front right teat and from 0.698 to 1.101 for the rear right teat.
