Abstract
The purpose of this study was to evaluate the success of artificial insemination using sexed semen based on different inseminators using the same bull in Friesian-Holstein cows. This study was conducted from January to October 2025. The subjects of this study were five inseminators from KAN Jabung and 649 Friesian-Holstein cows that were artificially inseminated using sexed semen from Glens bulls. Observations made on the inseminators included their skills in AI, such as: accuracy in insemination timing, semen selection, and semen thawing. The used bull semen was from Glens FH bulls. The research method used was quantitative descriptive. The parameters observed included Conception Rate (CR), Pregnancy Rate (PR), Service per Conception (S/C), and Inseminator Success. The data obtained were then analyzed with descriptive analytics method. The results showed that inseminator 1 produced the highest CR value with a percentage of 17.88%, while inseminator 4 produced the lowest CR with a value of 11.49%. The average CR value of the 5 inseminators was 14.16%. The PR value was highest for inseminator 1 with a percentage of 27.37%, while the lowest percentage was produced by inseminator 4 with a percentage of 12.64%. The average PR percentage of the 5 inseminators was 17.87%. The highest S/C value was produced by inseminator 2 with an S/C value of 1.05, while the lowest S/C value was produced by the inseminator 1 with an S/C value of 1.37. The average S/C value of the 5 inseminators was 1.19. The highest inseminator success percentage was obtained by inseminator 1 with a value of 21.12%, while the lowest value was obtained by inseminator 4 with a value of 11.22%. The average inseminator success percentage was 15.12%. It can be concluded that the success of artificial insemination using sexed semen is influenced by the quality of the semen, physiological conditions of dairy cows, the accuracy of semen deposition, abilities, and inseminator skills in performing AI.
