Vacuum fluctuations in milk tubeCorrelations among selected structural and functional characteristics areshown in table 2. Highly significant positive correlation (P < 0.01) wasfound between nominal vacuum and maximum short milk tube vacuumand significant negative correlation (P < 0.05) between air vent admissionand range of fluctuation of short milk tube vacuum.Table 2.

Ryšánek et al.Particular attention was paid to the frequency of excessive vacuum. Ascan be seen in table 3, no significant correlation was demonstrated betweenthis parameter and any of the selected structural characteristics. Negativecorrelation approaching the significance level was observed only betweenair vent admission and the frequency of excessive vacuum.Data on correlations between selected functional characteristics andoccurrence of teat injuries, given in table 4, indicate that significantrelationship described by a positive correlation coefficient can be expectedonly between the frequency of excessive vacuum and the occurrence ofhyperkeratosis.Functional characteristics of the up-to-date milking machines were ratheruniform. This finding reflects the unification of designs resulting from thecodification of the individual construction elements. It is rather surprisingthat the difference between milking machines with simultaneous andDiscussionTable 4.
