The aim of the authors was to evaluate the repeated measurement results of the four teat parameters measured with ultrasound. Our tests were carried out at a dairy farm near Pápa on Holstein-Friesian dairy cattle breed. The 4 parameters of the 20 teats were studied five times - the length of the teat canal, the 1cm area of the teat end, the parcial papillary 1cm distal area and the teat-end region. Statistical analysis was processed by the SPSS 18.0 software package. Parameters as follows, the mean values, the deviation values, the mean error and the minimum and the maximum values were analysed. With Kolmogorov-Smirnov test have verified the normal distribution of all data. The average values of five repetitions - with one exception: the teat-end area (between the 1st and the 3rd measurements) - were the same. The correlation coefficients calculated as 10 measurements of data pair combinations - for each of the four parameters - were positive, medium and very strong (r = 0.68-0.93; P <0.001).
