This paper has studied the potential reproductive fitness (physical/health condition, reproductive tract and sperm quality) of 98 bulls aged between 1 and 10 years, breed Charolais, Limousine and Retinta, distributed throughout Extremadura. This study intended to find the most useful seminal variables to differentiate breeders. Laboratory analyses have been a classic spermiogram (aspect of the ejaculate, volume, concentration, subjective motility and abnormal shapes) complemented by assessment of the mobility through CASA system (Computer Assisted Semen Analysis). In all cases the scrotal circumference has been measured. They have been classified as satisfactory, questionable and unsatisfactory potential breeders, considering both their phy...
