This study aimed to determine the effects of different semen diluent on the quality and storage time of liquid semen of Donggala bull. Semen was obtained from four selected bulls which collected using artificial vagina. The semen diluent is based on Tris aminomethane-citric acid with different concentration of glucose namely P1=0.00g, P2=0.25g, P3=0.50g, and P4=0.75g. Another group of treatment also prepared based on Tris aminomethane-glucose with different concentration of egg yolk namely P5=0%, P6=15%, P7=20%, and P8=25%. The data obtained were then analyzed descriptively. Results showed tris aminomethane-citric acid-glucose diluents had sperm progressive motile at >40% until the day 4 of storage, and tris aminomethane-glucose-egg yolk only able to support sperm life for 2 days, and in P8 group shows 41.02% motile on the day 3. In this study, we found the pattern of the increasing of shelf life affect to the decrease rate of sperm viability and normality.

Penelitian ini bertujuan untuk mengetahui tingkat keberhasilan inseminasi buatan pada Sapi Bali di Sindue Kabupaten Donggala. Penelitian dilaksanakan pada bulan November - Desember 2022. Data Inseminasi Buatan Sapi Bali diambil dari lima desa di Kecamatan Sindue dengan jumlah populasi sapi bali terbanyak yaitu Desa Toaya Vunta, Toaya, Enu, Kavaya dan Kumbasa dengan total induk sapi bali dalam program IB (akseptor) sebanyak 119 ekor. Penentuan lokasi penelitian dan responden dilakukan secara sengaja (purposive sampling). Parameter yang diamati yaitu Service per Conception (S/C) dan Conception Rate (CR). Data yang diperoleh dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa nilai rata-rata nilai S/C dan CR pada Tahun 2022 secara berturut-turut adalah 1,52 dan 55,46%. Nilai S/C dan CR tersebut dikategorikan cukup baik.
