The influence of gender on the body class and the share of commercial cuts of Istrian cattle

Istarsko govedo jedna je od tri autohtone pasmine goveda čija je revitalizacija usmjerena ka proizvodnji i plasmanu kvalitetnog i prepoznatljivog goveđeg mesa. Budući da je istarsko govedo kasnozrela pasmina nešto sporijeg ali dužeg intervala rasta, važno je u tovu mlađih kategorija goveda razumjeti načela dinamike promjene konformacije trupa i alometrije rasta tkiva obzirom na spol jedinki. Cilj rada je utvrditi utjecaj spola na konformaciju trupa i udjele komercijalnih rezova u trupu. Istraživanjem je obuhvaćeno 126 jedinki pasmine istarskog goveda uzgojenih na području Istre od kojih je 112 muških te 14 ženskih grla. Goveda su držana u tradicionalnim farmskim uvjetima, u zemaljskom farmskom uzgoju. Utvrđeno je da spol značajno utječe na masu toplih i hladnih, te klasu trupa, što se može obrazložiti različitom dinamikom rasta bikova odnosno krava (junica). Utvrđne razlike u masama komercijalnih rezova muških i ženskih jedinki značajne su u gotovo svim izmjerama, što potvrđuje značajan utjecaj spola na udjele komercijalih rezova istarskog goveda. Istraživanje treba nastaviti na većem broju jedinki, posebice ženskog spola kako bi mogla poslužiti kao smjerokaz u daljnjoj afirmaciji goveda kroz program proizvodnje mesa.Istrian cattle is one of three indigenous cattle breeds whose revitalization is directed towards the production and marketing of quality and recognizable beef. As the Istrian cattle are a latematured breed of a slightly slower but longer growth interval, it is important in the fattening of younger cattle categories to understand the principles of dynamics of carcass conformation and tissue growth allometry with respect to the sex of individuals. The aim of the paper is to determine the influence of gender on body conformation and the proportion of commercial cuts in the body. The study included 126 breeds of Istrian cattle bred in Istria, of which 112 were male and 14 female. Cattle were kept in traditional farm conditions, in farmland. Gender has been found to significantly affect the mass of warm and cold, and the carcass class, which can be explained by different dynamics of growth of bulls or cows (heifers). There were significant differences in the mass of commercial cuts of male and female jeniks in almost all measurements, which confirms the significant influence of sex on the proportions of commercial cuts of Istrian cattle. Research should continue on more individuals, especially females, so that they can serve as a waypoint in further affirmation of cattle through the meat production program
