Kualitas semen pejantan merupakan salah satu faktor penting yang menentukan keberhasilan reproduksi dan produktivitas ternak. Salah satu faktor yang memengaruhi kualitas spermatozoa adalah kecukupan mikro mineral, seperti seng (Zn), besi (Fe), mangan (Mn), dan kobalt (Co), yang berperan dalam proses spermatogenesis, metabolisme energi, dan sistem antioksidan spermatozoa. Keseimbangan mikro mineral dalam tubuh pejantan diduga berkaitan dengan kualitas semen dan tingkat fertilitas ternak. Penelitian ini bertujuan mengetahui kadar mikro mineral darah dan hubungannya dengan kualitas spermatozoa kambing Boerka. Penelitian menggunakan semen dan sampel darah dari lima ekor kambing Boerka pejantan. Pemeriksaan kualitas semen dilakukan secara makroskopis dan mikroskopis. Pemeriksaan makroskopis meliputi volume, warna, bau, dan konsistensi semen, sedangkan pemeriksaan mikroskopis meliputi konsentrasi spermatozoa, motilitas massa, motilitas individu, viabilitas, dan abnormalitas spermatozoa. Pemeriksaan kadar mikro mineral darah meliputi Zn, Fe, Mn, dan Co menggunakan metode Atomic Absorption Spectrophotometry (AAS). Data dianalisis menggunakan uji korelasi Pearson. Hasil penelitian menunjukkan bahwa kualitas semen kambing Boerka masih berada dalam kategori normal. Volume semen diperoleh sebesar 1,66±1,90 ml dengan warna krem, bau khas, dan konsistensi kental. Pemeriksaan mikroskopis menunjukkan konsentrasi spermatozoa sebesar 208,20±142,07×10⁶ sperma/ml, motilitas massa sebesar 2,40±0,55, motilitas individu sebesar 72,18±17,05%, viabilitas sebesar 66,91±16,96%, dan abnormalitas sebesar 2,22±1,49%. Kadar mikro mineral darah yang diperoleh yaitu Zn sebesar 0,76±0,23, Co sebesar 0,01±0,01, Fe sebesar 2,63±2,16, dan Mn sebesar 0,22±0,28. Hasil analisis menunjukkan bahwa tidak terdapat hubungan yang signifikan antara kadar mikro mineral darah dengan kualitas spermatozoa kambing Boerka (P>0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa kadar mikromineral darah kambing Boerka masih berada dalam kisaran fisiologis normal dan belum menunjukkan hubungan yang signifikan terhadap kualitas spermatozoa.

Semen quality is one of the important factors determining reproductive success and livestock productivity. One of the factors affecting sperm quality is the adequacy of microminerals, such as zinc (Zn), iron (Fe), manganese (Mn), and cobalt (Co), which play important roles in spermatogenesis, energy metabolism, and the antioxidant system of spermatozoa. The balance of microminerals in breeding males is suspected to be associated with semen quality and fertility. This study aimed to determine blood micromineral levels and their relationship with sperm quality in Boerka goats. The study used semen and blood samples collected from five male Boerka goats. Semen quality evaluation was performed through macroscopic and microscopic examinations. Macroscopic examination included semen volume, color, odor, and consistency, while microscopic examination included sperm concentration, mass motility, individual motility, viability, and sperm abnormalities. Blood micromineral levels of Zn, Fe, Mn, and Co were analyzed using Atomic Absorption Spectrophotometry (AAS). Data were analyzed using Pearson correlation analysis. The results showed that the semen quality of Boerka goats was within the normal range. Semen volume was 1.66±1.90 mL with cream color, typical odor, and thick consistency. Microscopic examination showed sperm concentration of 208.20±142.07 ×10⁶ sperm/mL, mass motility of 2.40±0.55, individual motility of 72.18±17.05%, viability of 66.91±16.96%, and abnormalities of 2.22±1.49%. The blood micromineral levels obtained were Zn at 0.76±0.23, Co at 0.01±0.01, Fe at 2.63±2.16, and Mn at 0.22±0.28. Correlation analysis showed that there was no significant relationship between blood micromineral levels and sperm quality parameters in Boerka goats (P>0.05). It can be concluded that the blood micromineral levels of Boerka goats were still within the normal physiological range and had no significant relationship with sperm quality.
