The differences in teat-end hyperkeratosis in Holstein and Jersey dairy cows

The objective of this study was to evaluate the effect of breed (Holstein ; HB/Jersey ; JB) on the teat-end hyperkeratosis score (TEH) of cows housed in the same farm conditions and under the same milking management. Jersey cows had better score for the front teats, but worse for the rear teats comparing to Holstein cows. The TEH of the front teats in JB cows in third lactation were significantly (P<0.05) lower comparing to the same lactation group of HB cows. Regarding the rear teats of the observed cows, significantly (P<0.05) higher hyperkeratosis score was found in Jersey cows in first lactation comparing to Holstein cows in same lactation. The somatic cell count was found to be higher in JB comparing to the HB cows, but not significantly. The obtained results indicate that breed influence the level of the teat tissue condition.
