Analysis of the Grey Colour Intensity in Horses
Published September 22, 2004
3-7

An investigation of different grey coat colours and a connection between colour and age of horses was carried out with two Hungarian State Studs: Bábolna and Szilvásvárad. For objective measurement of coat colour Minolta Chromameter (Model CR-210) was used. The average value of L (lightness) level by Shagya and Pure Bred Arabian horses was 6...3.83 ± 2.23, for Lipizzan horses was x=71.00 ± 2.29 respectively. In each stud older horses (over 10 years of age) have a flea-bitten colour stage, which decreased the L value considerably. Changes in coat colour in connection with the greying process did not show an evident tendency in the three breeds.

Additional data for the evaluation of coat colour varieties in the Hungarian Grey cattle
Published July 16, 2007

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 herita...ge. 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.
