Semen adalah cairan yang dikeluarkan oleh organ kelamin jantan yang secara normal diejakulasikan ke dalam saluran reproduksi betina melalui kopulasi. Evaluasi kualitas semen merupakan alat utama untuk memprediksi kinerja reproduksi ternak jantan. Kualitas semen ayam dipengaruhi oleh banyak faktor diantaranya jenis ayam. Penelitian ini bertujuan untuk Mengetahui perbandingan karakteristik kualitas semen ayam kampung, ayam kate dan ayam hutan merah secara makroskopis dan mikroskopis. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan jenis bangsa ayam lokalyaitu ayam kampung, ayam kate dan ayam hutan merah dengan tiga kali ulangan. Hasil penelitian didapatkan volume semen ayam kampung 0,28±0,03 mL/ejakulasi lebih tinggi dari ayam kate 0,17±0,06 mL/ejakulasi, dan ayam hutan 0,15±0,05 mL/ejakulasi. pH semen Ayam kampong 7,33±0,31, tidak berbeda dengan ayam kate 7,07±0,31 dan ayam hutan merah 7,20±0,20. Ayam kampung memiliki konsentrasi spermatozoa 2260,00 ±104,40 juta/mL, lebih tinggi dari pada ayam kate 1980,00 ± 157,16 juta/mL, dan ayam hutan 1736,67 ± 317,86 juta/mL. Motilitas spermatozoa ayam kampung 85,11±3,29%, ayam kate 80,43±1,82%, dan ayam hutan merah 82,05±2,83 %. Viabilitas spermatozoa ayam kampung 87,61±2,94 %, ayam kate 85,05±2,63 %, dan ayam hutan merah 86,91±1,84 %. Abnormalitas spermatozoa ayam kampung 6,63±0,95 %, ayam kate 6,79±1,52%, dan ayam hutan merah 7,58±1,43%. Dari hasil penelitian dapat disimpulkan bahwa: Volume semen dan konsentrasi spermatozoa ayam kampung, lebih tinggi secara nyata (P0,05).

Semen is a fluid secreted by the male reproductive organs and is typically ejaculated into the female reproductive tract during copulation. Assessing semen quality is an important tool for predicting the reproductive performance of male cattle. The quality of chicken semen is influenced by various factors, including the chicken breed. This study aimed to compare the macroscopic and microscopic characteristics of semen quality among country chickens, bantam chickens, and red jungle fowl. A completely randomized design (CRD) was employed in this study, using local chicken breeds with three replications. The results revealed that the semen volume of country chickens was approximately 0.28 ± 0.03 mL/ejaculate, which was higher than that of bantam chickens (0.17 ± 0.06 mL/ejaculate) and red jungle fowl (0.15 ± 0.05 mL/ejaculate). The pH of country chicken semen was approximately 7.33 ± 0.31, similar to that of bantam chicken semen, while red jungle fowl semen had a pH of about 7.20 ± 0.20. The spermatozoa concentration in country chickens was approximately 2260.00 ± 104.40 million/mL, which was higher than that of bantam chickens (1980.00 ± 157.16 million/mL), while red jungle fowl had a concentration of about 1736.67 ± 317.86 million/mL. The motility of country chicken spermatozoa was approximately 85.11 ± 3.29%, bantam chicken had a motility of about 80.43 ± 1.82%, and red jungle fowl exhibited a motility of around 82.05 ± 2.83%. The spermatozoa viability in country chickens was approximately 87.61 ± 2.94%, bantam chicken had a viability of about 85.05 ± 2.63%, and red jungle fowl had a viability of approximately 86.91 ± 1.84%. Regarding abnormal spermatozoa, country chickens had a percentage of about 6.63 ± 0.95%, bantam chickens had 6.79 ± 1.52%, and red jungle fowl exhibited 7.58 ± 1.43%. Based on the study's findings, it can be concluded that the semen volume and spermatozoa concentration of country chickens were significantly higher (P0.05) observed in the pH, color, consistency, motility, viability, and abnormal spermatozoa characteristics among country chickens, bantam chickens, and red jungle fowl.
