Abstract
The aim of this work was to establish the external factors affecting morphological scores in competitions of Pura Raza Español (PRE – Spanish Purebred) horses. The dataset included 8633 participations, in 69 different morphological competitions of 5097 horses, belonging to 1113 studs. In total, the dataset had 21,760 records (each with eight partial morphological scores) with a balanced frequency of males and females. Our results showed that there are several external factors that influence the judges’ scores. Morphological competition (15.70% of the total variance), judge (9.65%), judge*morphological competition (7.45%) and judge*type (2.41%) were the most important external factors in the analyzed traits. The reliability of judgements was evaluated by the index of disagreement, and results showed that it might be necessary to train judges to get more agreement in these scores. Moreover, for a breeding program it is very important that judges use all the range of scores in order to collect the maximum level of variation. The analyses showed that competitions with three judges were the most appropriate. © 2014 Friends Science Publisher
