Abstract
The purpose of this study was to determine the effect of inseminator differences on the success of artificial insemination of Friesian-Holstein crossbred cows at KAN Jabung. This study was conducted from January 2025 to October 2025. The subjects of this study were eight inseminators at the Jabung Agricultural Trade Cooperative with the following criteria: at least one year of AI experience, a minimum of 50 AI doses, an official inseminator certificate, aged between 20 and 65 years, and adequate skills in performing AI, such as thawing, semen deposition, and timing of AI. The variables used in this study were Conception Rate (CR), Pregnancy Rate (PR), Inseminator Success, and Service per Conception. The data obtained were then analyzed using the chi-square method for non-numerical variables, the ANOVA method for numerical variables, and descriptive analytics for supporting variables. The results showed that the highest CR percentage was obtained by inseminator 7 with a CR percentage of 48.78%, while the lowest CR percentage was obtained by inseminator 8 with a percentage of 6.66% and an average CR percentage for all inseminators of 24.72%. The highest PR percentage was obtained by inseminator 6 with a percentage of 60%, while the lowest PR percentage was obtained by inseminator 8 with a PR percentage of 13.33% with an average PR percentage of all inseminators of 34.87%. The highest insemination success rate was achieved by inseminator 6 with an insemination success rate of 50.94%, while the lowest insemination success rate was achieved by inseminator 8 with an insemination success rate of 12.12% and an average insemination success rate for all inseminators of 25.95%. The highest S/C value was obtained by inseminator 7 with a value of 1.04, while the lowest S/C value was obtained by inseminator 2 with a value of 1.84, with an average S/C value for all inseminators of 1.38. Based on the results of the study, it can be concluded that the success of pregnancy is influenced by differences in the abilities, skills, and experience of inseminators in performing artificial insemination.
