Resumen: Abstract: The objective of the work was to evaluate the spermatic quality in Pelon Mexicano boars from Yucatan. Three boars of said genotype were used, which were trained to mount a dummy. The study variables were: macroscopic and microscopic characteristics, semen motility kinetic parameters, and testicular characteristics. A total of 42 seminal samples were evaluated, the results were analyzed with descriptive statistics, cluster analysis, correlation and linear regression with the STATGRAPHICS Centurión XV Version 15.2.06 ® program. The odor was normal, average volume 76.81mL and milky color. Individual motility, sperm concentration, morphology, vitality, and acrosomal integrity were: 80.24%, 237.54 X106 esp/ml, 94.71%, 85.62%, and 99.40%, respectively; while the curvilinear speed, rectilinear speed, average speed, linearity index, straightness index, oscillation index, lateral displacement of the head, and crossing frequency, were: 75.81mm/s, 40.24 mm/s, 57.05 mm/ s, 52.46%, 68.75%, 73.65%, 2.45 mm/s, and 7.93 Hz, respectively. A relationship was found between the variables of concentration, volume and motility (P?0.001), likewise, it was observed that the collection weeks significantly affected the variables of concentration, morphology, motility and vitality (P?0.01). The 1815SG stallion presented the highest values for all the testicular variables evaluated, keeping a direct relationship with a greater volume and sperm concentration. Finally, with the cluster analysis, for acrosomal integrity (99.57%), volume (122ml) and sperm concentration (390x106 esp/ml), the best semen quality parameters corresponded again to the 1815SG stallion. The semen evaluation techniques used guarantee greater precision and reliability in the evaluation of semen quality in Pelón Mexicano boars from Yucatán.
