Abstract :This study aimed to assess the effect of genetic and seasonal interaction on semen quality in the Artificial Insemination Center. A total of 36,754 ejaculation records were evaluated. The dependent variable was semen quality which consisted of volume, pH, concentration, abnormalities, and motility of fresh semen. The independent variables consisted of age, season, and number of ejaculation. The mixed procedure with Tukey–Kramer multiple comparison test was used to analyze the effect of interaction between the variables. Seasonal factors significantly affected concentration, fresh semen motility, and abnormality, but did not affect pH and volume. Age factor had a significant effect on all semen quality variables. The ejaculation factor significantly affected pH, volume, concentration, and fresh semen motility, but did not affect abnormality. The species factor significantly affected pH, concentration, and fresh semen motility, but did not affect volume and abnormality.
