Abstract

The present research was conducted to investigate the potency and viabitity of oocytes of Simmental cattle for production of embryo in in-vitro method. Oacytes were collected from the ovaries of slaughtered Simmental cattle. At first, the ovaries were cleaned and measured for weigh, length, diameter and thickness. The ovaries were then sliced to collect oocyte follicles. The collected oocytes which were devided into 3 groups based on length size (<2, 2-6 and >6 mm) were kept in ringer solution (0,9 % Nacl) by temperature of 35oC. By using microscope the physical performances of the oocytes were observed and then classified into 3 different qualities of A, B and C/D. The oocytes of A ond B quality were kept in TCM-199 medium for maturity process. Their viability was described as percentage af oocytes which reach metaphase II (M-II). stage during the proces of maturity. The data was statistically analyzed by t-test. Results of the experiment showed that the physical measurement af ovaries were found significant diferent (P>0,05) between the left and right sides, but the potency of follicles from the both sides were not significant different (P>0,05). The percentage of oocytes reach the metaphase II stage was about 51,28 s/d 13,65 %. It was concluded that Simmental has a high the potency and viability oocytes for embryos production in vitro.

Abstract

Tujuan penelitian ini adalah untuk mengidentifikasi potensi sapi potong di Kecamatan Bayang Kabupaten Pesisir Selatan demi mewujudkan produksi bibit sapi potong unggul. Materi dalam penelitian ini adalah 361 orang peternak sapi potong sebagai responden. Metode yang digunakan adalah sensus dan Stratified Random Sampling. Peubah yang diukur adalah komposisi dan struktur populasi, penampilan reproduksi, natural increase (NI), net replacement rate (NRR) dan Dinamika/Estimasi populasi ternak sapi potong. Analisis data dilakukan dengan pendekatan teori pemuliabiakan ternak dan analisis time series. Hasil yang didapatkan menunjukkan komposisi ternak sapi potong di Kecamatan Bayang Kabupaten Pesisir Selatan terdiri dari sapi Pesisir (50,15%), sapi SimPes (25,80%), Bali (17,06%), sapi SimPO (3,75%), dan Brahman Cross (2,18%). Persentase sapi potong yang keluar yaitu 6,12%, lebih banyak dibandingkan dengan persentase ternak sapi potong yang masuk yaitu 5,10%. Nilai natural increase (NI) ternak sapi mendapatkan presentase sebesar 17,64% yang melihatkan pertambahan populasi sapi potong termasuk kategori sedang. Nilai net replacement rate (NRR) ternak sapi jantan (1311,42 %) dan sapi betina (674,34%). Estimasi populasi sapi potong pada tahun 2017 sebanyak 2093,40 ekor dan tahun 2021 kekurangan sapi potong sebanyak 258,60 ekor dimana rataan terjadinya penurunan populasi pertahun sebanyak 783,92 ekor atau 25,83%. Kesimpulan dari penelitian ini menyatakan bahwa Kecamatan Bayang Kabupaten Pesisir Selatan Provinsi Sumatera Barat dinyatakan layak untuk menjadi daerah pembibitan sapi potong.
