Assessment scale for behaviour in bulfighting cattle (EBL 10): Reliability and validity

Our intention is to objectively assess the behavior patterns related to bravery in bullfighting cattle by means of a scale devised for this purpose. Reliability and validity studies have been carried out. This instrument will allow researchers to analyse inherited behaviour characters, permitting breeders to select in a more objective and systematic way. The evaluation scale of bravery in Fighting bovines, EBL 10, has been constructed. A glossary has also been developed with the distinguishing definitions of the ten dimensions dealt with, as well as a set of objective indicators for each dimension. A feasibility and validity study of the scale has been undertaken, assessing a sample made up of 380 bulls' behavior during a bullfight. Previously, a reliability study was carried out by two evaluators in a sample of 116 cows during a practical bravery test, (tienta). The scale (EBL 10) is a valid and reliable tool for standard behavior assessment related to bravery in fighting bovines and may be useful for both researchers and breeders alike.
