Horn colour varieties of the Hungarian Grey cattle
83-87Views:123The Hungarian Grey Cattle breed is a ‘success-story’ of the national genetic conservation work. Traits of the breed have been subjects of several research projects, although many relationships remained unclear. Our present research results were meant to call attention to a less emphasized trait of the breed: the different horn colour varieties. Research work was carried out in the Hungarian Grey stock of the Hortobágy Non-profit Company for Nature Conservation and Gene Preservation. Ratio of the three main horn colour varieties (white, ‘cardy’, green) were determined in the observed female, male and steer stocks. Our results showed no significant differences (P<0,05) in the distribution of the horn colour varieties of the female and bull stocks, and of the female and steer stocks. We found that on the basis of the ratio of white colour, four sub-categories can be distinguished within the ‘cardy’ colour variety. Results of the statistical analysis (P<0,05) confirmed that the colour of the horn and the ratio of the black part on the horn tip are two different traits.

Comparative Evaluation of the Temperaments of Charolais and Hungarian Grey Steers
14-19Views:137Animal breeding increasingly lays claim to the theoretical and practical knowledge of applied ethology. The authors’ aim was to evaluate and compare the temperaments of Charolais (CH, n= 10) and Hungarian Grey (HG, n= 10) steers, and also to determine the correlation between their temperament scores and flight speed scores. Temperament was evaluated by the results of the scale test (assessing of behaviour in a 1-5 score system, while the animal is standing on a scale for 30 seconds) and flight speed test (minutes it takes the animal to move a set distance of 1.7 m when leaving the scale), on three occasions (1, 2, 3). Data management was done by SPSS.10 (ANOVA, Mann-Whitney-test, Spearman-correlation). Results of the scale test differed significantly between breeds at the third measurement (CH: 2,9 scores; HG: 1,4 scores; P<0,01) and when evaluating the three measurements together (CH: 2,0 scores; HG: 1,37 scores; P<0,05). Concerning of flight speed score, there were significant differences between breeds of steers at each measurement (1. measurement CH: 2,77 s; HG: 4,09 s; P<0,05; 2. measurement CH: 2,89 s; HG: 5,01 s; P<0,01; 3. measurement CH: 2,46 s; HG: 5,33 s; P<0,01) and overall (CH: 2,71 s; HG: 4,81 s; P<0,001). In the case of both breeds, evaluated by measurements and overall, a negative correlation was calculated between temperament score and flight speed score, but this was significant only in three cases: CH1 (n=10) r= -0,75; P<0,01; CH1+2+3 (n=30) r= -0,44; P<0,05; CH+HG1+2+3 (n=60) r= -0,33; P<0,01). Results indicate that Hungarian Grey steers are calmer than individuals of Charolais. Animals behaving calmer on the scale left the scale, more slowly. The authors propose the use of these temperament tests in Hungarian breeding practice, in order to select too temperament animals.
