Abstract

Factors affecting the milk ejection intensity and power consumption of the pulse generator combined with the milking machine collector have been analyzed. The main factors and limits of their variation, as well as the results of experimental studies are given. The matrices of a multivariate planned experimental study of a pulse generator with a combined collector (pneumatic-electromagnetic pulsator-collector) have been developed. According to the results of experimental studies, the coded and natural values of the regression equation are derived. The equations characterize the dependence of the milk ejection intensity on the pulsation frequency, the ratio between the strokes and the vacuum pressure in the under teats space of the teat cup. The dependence of the power consumption of the pulse generator on the pulse rate and the ratio between the strokes are derived. Graphical models of interpretation of regression dependencies according to the experimental data are constructed. Student's t-test, Fisher and Cochran criteria are calculated. These indicators show the adequacy and reproducibility of the models obtained during the studies using an experimental pulse generator combined with a milking machine collector.
