Abstract

ABSTRAK AndroMed merupakan pengencer semen komersial berisi bahan kimia yang komplit namun tidak mengandung kuning telur, sehingga diharapkan tidak ada kontaminasi mikroorganisme. Penelitian ini bertujuan menguji kualitas spermatozoa epididimis domba yang dibekukan dengan pengencer Tris dan AndroMed. Spermatozoa diencerkan dengan perlakuan pengencer sebagai berikut: pengencer Tris (Tris), 15% AndroMed + 85% akuabidestilata (AM15), 20% AndroMed + 80% akuabidestilata (AM20), dan 25% AndroMed + 75% akuabidestilata (AM25). Kualitas spermatozoa yang diamati terdiri atas: konsentrasi spermatozoa, persentase spermatozoa motil, spermatozoa hidup, abnormalitas, butiran sitoplasma, dan membran plasma utuh (MPU). Hasil penelitian menunjukkan bahwa rata-rata konsentrasi spermatozoa, persentase spermatozoa motil, spermatozoa hidup, abnormalitas, butiran sitoplasma, dan MPU spermatozoa segar adalah masing-masing: 11.660 juta/ml, 65%, 81%, 7,6%, 10,2%, dan 82,2%. Tidak terdapat perbedaan yang nyata antarperlakuan terhadap persentase spermatozoa motil, spermatozoa hidup, dan MPU pada tahap setelah pengenceran dan ekuilibrasi. Pada tahap setelah thawing, rata-rata persentase spermatozoa motil, spermatozoa hidup, dan MPU dari perlakuan AM20 dan Tris secara nyata (P<0,05) lebih tinggi dibandingkan dengan AM15 dan AM25. Hasil penelitian ini menyimpulkan bahwa pengencer semen komersial AndroMed dan Tris memiliki kemampuan yang sama dalam melindungi spermatozoa domba pada proses pembekuan semen. Konsentrasi 20% AndroMed merupakan dosis optimum dalam proses pembekuan spermatozoa epididimis domba. Kata kunci: spermatozoa epididimis domba, kriopreservasi, Tris, AndroMed ABSTRACT The AndroMed is a semen extender made from a completely mixed ingredients without egg yolk, therefore the AndroMed is microorganism-free extender. The purpose of this research was to examine the quality of frozen-thawed ram epididymal spermotozoa cryopreserving with Tris and AndroMed extenders. The spermotozoa was diluted with Tris extender (Tris), 15% AndroMed + 85% distilled water (AM15), 20% AndroMed + 80% distilled water (AM20), and 25% AndroMed + 75% distilled water (AM25), respectively. The quality of collected spermatozoa were concentration, percentages of motile, liveability, abnormality, cytoplasmic droplet, and intact plasma membrane (IPM) spermatozoa. The results showed that mean concentration, percentages of motile, liveability, abnormality, cytoplasmic droplet, and IPM of fresh spermatozoa were 11,660 million/ml, 65%, 81%, 7.6%, 10.2%, and 82.2%, respectively. There were no significant differences in percentages of motile, live, and IPM spermatozoa between treatments after dilution and equilibration stages. The mean percentages of post thawing motile, liveability, and IPM spermatozoa of AM20 and Tris were higher (P<0.05) than AM15 and AM25. The AndroMed and Tris extenders had the same ability to protect spermatozoa in cryopreservation process. The concentration of 20% AndroMed was optimum dose in cryopreservation process of ram epididymal spermatozoa. Keywords: ram epididymal spermatozoa, cryopreservation, Tris, AndroMed
