Tingkat Kematangan Inti Oosit Sapi Setelah 24 Jam Presevasi Ovarium

Abstract: The objective of the research was to investigate their meiotic competence or nuclear maturity of bovine oocytes maturity in vitro after 24 hour preservation on 5°C. Oocytes were collected by slicing the ovaries in modified phosphate buffer saline (m-PBS). Selected cumulus-oocyte complexes (COCs) homogenous ooplasm were cultured in maturity medium at 38°C in humidified atmosphere of 5% CO 2 incubator. After 24 hours, oocytes stained for nuclear maturity's evaluation. The proportion of oocytes at metaphase II (M… Show more

“…Cumulus-oocyte complexes (COCs) were then collected using the slicing method in Dulbecco's Phosphate-Buffered Saline (DPBS) (Sigma, USA) and supplemented with 5% fetal bovine serum (FBS) (Gibco, USA), 100 IU/mL penicillin (Meiji, Japan), and 0.1 streptomycin mg/mL (Meiji, Japan). According to the previous methods (Widyastuti et al, 2017;Widyastuti and Rasad, 2015), the COCs selected for culture were classified based upon the CC layer, and only oocytes with homogenous cytoplasm were selected. In this study, COCs with a minimum of two CC layers were selected for the IVM culture program with different culture environment systems.…”

“…Kemajuan teknologi reproduksi pada ternak memungkinkan masalah penurunan populasi yang terjadi pada ternak juga dapat diatasi. Salah satu upaya yang dilakukan dalam mengatasi masalah tersebut adalah pemanfaatan program inovasi teknologi reproduksi dengan memperpendek selang beranak, melalui manipulasi berahi dan superovulasi (Widyastuti dan Rasad, 2015). Selain itu teknologi reproduksi yang dapat diaplikasikan untuk meningkatkan populasi ternak kerbau adalah dengan produksi embrio secara in vitro (PEIV).…”
