Summary

A field survey with 70 cows in 15 herds was carried out to find a possible correlation between the depth of teat penetration into the teatcup liner during milking, and udder health. The investigation showed that the depth of penetration into the liner of fore teats was positively correlated with the fore teat end hardness (P < 0·01), and with the frequency of clinical mastitis for the whole udder (P < 0·1). The investigation also showed that the teat end height above the floor was negatively correlated with mean cell count for the previous year (P < 0·001), and with the prevalence of subclinical mastitis in rear quarters (P < 0·05).
