Abstract

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.

Abstract (english)

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.
