Abstract
Uspješna mužnja podrazumijeva sekreciju maksimalne količine mlijeka u što kraćem roku bez negativnih posljedica na zdravlje samih životinja. Na mužnju utječe niz faktora među kojima se kao najznačajniji ističu vrsta sisne gume te vakuum koji se javlja u njenom vršnom dijelu. Odabir neadekvatnih sisnih guma direktno utječe na tkivo sise, a indirektne posljedice su vidljive u obliku nepoželjnih razina vakuuma koje se stvaraju prilikom mužnje. Visoke razine vakuuma povećavaju rizik od pojave bolesti, a jedan od načina regulacije razina vakuuma tijekom mužnje je ventilacija sisnih guma. Ovo istraživanje se provodilo na muznim kravama pasmine Holstein-Friesian pri čemu su se pratili vakuum u vršnom dijelu sisne gume te kretanje sisne gume. Statistički značajni efekti modela su vrsta sisne gume, ventilacija sisne gume te interakcija između vrste sisnih guma te ventilacije.
Abstract (english)
Successful milking implies the secretion of the maximum amount of milk in the shortest possible time without negative consequences for the health of the animals themselves. Milking is affected by a number of factors, among which the type of teat rubber and the vacuum that occurs in its peak stand out as the most important. Choosing inadequate liners directly affects the teat tissue, and indirect consequences are visible in the form of undesirable vacuum levels that are created during milking. High vacuum levels increase the risk of disease, and one way to regulate vacuum levels during milking is to ventilate the liners. This research was conducted on dairy cows of the Holstein-Friesian breed, where the vacuum in the mouthpiece chamber and the movement of the liners were monitored. Statistically significant effects of the model are the type of liners, ventilation of the liners and the interaction between the type of liners and ventilation.
