Abstract
The aim of the study is to compare the scores given to the condition of Charolais cows (the herd of Abauj Charolais Corp., Dicháza, Hungary, spring of 2011) (n=213, live weight: 695.6±73.18 kg, age: 5.9±2.06 years) before the grazing season by two independent conformation judges (person A and B). The scoring system (1-9 points) according to Whitman (1975) was used for evaluating the condition. The average condition scores given by the two judges were different only in the second decimal place (A: 5.76, B: 5.74 points). The median, modus, minimum and maximum values were equal, but the standard deviation was higher (although not significantly) in case of the B judge (A: 0.544, B: 0.610). By Pearson χ2 test it could be proved that the condition scores given by the two persons are statistically not independent (319.24, df: 9, p=0.0001), cause their results are highly similar. The value of Spearman correlation is r=0.76 (p=0.0001), which also indicates the similarity of the scores given by the two judges. These results may support spreading the practice of condition judgement further in Hungary.
