Abstract
When preserving genetic resources, one of the most important tasks is to conserve as much of the given gene pool for the future generations as we can. Therefore, traits that have no economic value at the moment should also be conserved. The great variety of coat colours seen in the Hungarian Grey cattle form part of the world’s genetic heritage. In order to maintain the world’s genetic diversity, we have to maintain these varieties, as well. The different coat colour varieties were determined – in both sexes and in several age groups – with a Minolta Chromameter CR-410 in an objective way. We found that the rate of the three main coat colour varieties of calves: the light reddish, the reddish and the dark reddish were 26%, 52% and 22%, respectively. Statistically significant differences were found between the L*a*b* values of the reddish coat colour of the Hungarian Grey and the red coat colour of the Limousin calves. The rate of the crane, the grey and the light grey coat colour varieties were determined in the measured female groups. The L*a*b* values of the Hungarian Grey and Maremman bulls’ coat were compared and evaluated.

E fajta esetében számos másodlagos értékmérő megőrzéséről kell gondoskodnunk: a termékenység, a könnyű ellés, a jó borjúnevelő képesség, az ellenállóképesség, az igénytelenség, a kondíciótartás és a szervezeti szilárdság olyan fontos tulajdonságok, melyek a termelés gazdaságosságát is jelentősen befolyásolják. „non-food function” tulajdonságok is, melyek gazdasági hasznot általában nem hajtanak, de megőrzésük a biológiai diverzitás fenntartása érdekében mindenképpen indokolt. Ide sorolhatók a magyar szürke szarvasmarhára jellemző különböző szőrszín-változatok is, melyek nemcsak a korral, de az évszaktól függően is változnak
