Research on the potential of lactose against post-maturation and postcryopreservation events of oocyte core swollen of garut sheep (Ovis aries L.) has been carried out. The purpose of this study was to analyze the ability of lactose and to find the best concentration in visualizing the oocyte core (swollen) of garut sheep (Ovis aries L.) after maturation and post-cryopreservation. A total of 143 oocytes with A and B qualities (homogeneous cytoplasm, intact zona pellucida, and a cumulus layer of more than 4 layers) were saturated in TCM-199 medium with the addition of Bovine Serum Albumin (BSA). Oocytes with core status reached Metaphase II (M-II) as a result of in vitro maturation, then treated with various concentrations of lactose to see the core swollen event. Lactose treatment was also given to post-cryopreservation oocytes by taking into account the normal and viable conditions of oocyte metabolism. Oocyte core swollen was observed using Hoechst & PI stain under fluorescence microscope. The results showed that the difference between concentrations by Kruskal-Wallis test (P> 0.05) and 3% lactose concentration showed that the highest percentage of oocyte nucleus swollen events in post-maturation oocytes (58.22%) and also in post-cryopreservation oocytes (48.83 %). Post-maturation oocyte nucleus swollen events at 3% lactose concentration had a significant difference compared to 0%, 1%, and 5% lactose concentrations. The post-cryopreservation of oocyte core swollen at 3% lactose concentration was no significant difference with 0%, 1%, and 5% lactose concentrations. Lactose has the ability to swollen the nucleus of garut sheep oocytes and the 3% lactose concentration is the best concentration capable of causing postmaturation and post-cryopreservation of arrowroot oocyte core swollen events."

Research on maltose administration on the oocyte nuclear visualization of garut sheep (Ovis aries L.) after maturation and post-cryopreservation using the slow freezing method has been carried out. The aim of this study was to evaluate the ability of maltose and determine the optimum concentration of maltose that induces post-maturation and post-cryopreservation of swollen oocyte nuclear. In this study, garut sheep (Ovis aries L.) were used as animal models. The study was compiled based on completely randomized design consisting of two trials, four treatment groups, and six replications. In the first experiment, to ripen the oocytes in the Metaphase II stage, observations were made with the addition of various concentrations of maltose (0%, 1%, 3%, and 5%). Second, the Metaphase II oocytes obtained were continued to the cryopreservation stage with the slow freezing method. Furthermore, it was thawed and observed by adding various concentrations of maltose (0%, 1%, 3%, and 5%). The parameter used for oocyte maturation was Metaphase II which was characterized by the formation of a Polar Body I. The nuclear viability of swollen oocytes was observed using Hoechst & PI dyes. Meanwhile, swollen oocyte nuclear which is marked by the presence of a clear zone is a parameter used post-maturation and post-cryopreservation. The results showed that there were differences between concentrations statistically based on the Shapiro-Wilk normality test, the Levene homogeneity test, and ANOVA variance test (P ≥ 0.05) and the 3% maltosa concentration showed the highest percentage of post-maturation swollen oocyte nuclear (66.14%) and the highest percentage of post-cryopreservation swollen oocyte nuclear (70.96%). Therefore, the 3% maltose concentration is the optimum concentration to cause swollen post-maturation and post-cryopreservation of oocyte nuclear."

"Sebagai salah satu sumber daging di Jawa Barat, domba garut dapat mengalami penurunan mutu genetik akibat perkawinan dalam populasi yang tak terkontrol, sehingga perlu dilakukan konservasi dengan metode vitrifikasi. Sebelum divitrifikasi, oosit dimaturasi terlebih dahulu dengan penambahan alfa-tokoferol dalam medium maturasi yang berfungsi untuk mengurangi pengaruh negatif Reactive oxygen species ROS selama proses maturasi. Penelitian ini dilakukan untuk mengetahui kemampuan antioksidan alfa-tokoferol dalam meningkatkan kemampuan maturasi oosit dan mempertahankan kualitas dan viabilitas oosit domba garut Ovis aries hingga proses vitrifikasi. Sebanyak 125 oosit kualitas A dan B dimaturasi dalam medium maturasi TCM-199 dengan penambahan alfa-tokoferol sebanyak 0 M KK, 100 M KP1, 150 M KP2, dan 200 M KP3. Oosit yang telah matang divitrifikasi dengan krioprotektan etilen glikol 15 dan dimetil sulfoksida 15. Viabilitas oosit dianalisis dengan pewarna Hoechst dan Propidium Iodide. Berdasarkan hasil penelitian, diperoleh persentase oosit matang pascamaturasi, yaitu 66,67 KK, 66,67 KP1, 70,73 KP2, dan 82,50 KP3. Persentase viabilitas oosit pascavitrifikasi, yaitu 82,14 KK, 87,50 KP1, 93,55 KP2, dan 84,00 KP3. Persentase kualitas oosit pascavitrifikasi, yaitu 53,57 KK, 54,17 KP1, 58,06 KP2, dan 24,00 KP3. Hasil penelitian menunjukkan bahwa penambahan alfa-tokoferol memberikan pengaruh terhadap tingkat kematangan oosit, viabilitas, dan kualitas oosit pascavitrifikasi, meskipun secara statistik tidak menunjukkan perbedaan antarperlakuan. Penambahan alfa-tokoferol cenderung meningkatkan laju maturasi pada konsentrasi yang lebih tinggi 150 M dan 200 M. Penambahan alfa-tokoferol pada tahap maturasi dapat meningkatkan stabilitas membran, sehingga viabilitas dan kualitas oosit dengan penambahan alfa-tokoferol 150 M pascavitrifikasi menjadi lebih baik dibandingkan dengan kontrol. Pada oosit yang abnormal pascavitrifikasi, tipe kerusakan dibagi menjadi perubahan bentuk oosit, homogenitas sitoplasma, keutuhan sitoplasma dan tingkat kerusakan pada zona pelusida. Kerusakan zona pelusida menjadi kerusakan yang paling mempengaruhi viabilitas dan perkembangan oosit di tahap selanjutnya, seperti fertilisasi. Penambahan antioksidan alfa-tokoferol 150 M dalam medium maturasi merupakan konsentrasi yang optimal dalam mempertahankan viabilitas dan kualitas oosit pascavitrifikasi.

As a source of meat in West Java, Garut sheep genetic quality can decreased by uncontrolled mating within population, so it needs to be conserved by vitrification method. Before vitrification, Oocytes must be matured first with addition of alpha tocopherol in a maturation medium which to reduced the negative effect of Reactive oxygen species ROS during the maturation process.

This study was conducted to determine the ability of alpha tocopherol antioxidants in improving the ability of oocyte maturation and maintain the quality and viability of sites Garut sheep until vitrification process. As many as 125 oocytes with grade A and B were matured in a TCM 199 maturation medium with the addition of alpha tocopherol of 0 M KK, 100 M KP1, 150 M KP2, and 200 M KP3. The matured oocytes was vitrified by cryoprotectant ethylene glycol 15 and dimethyl sulphoxide 15. The viability of oocyte was analyzed by Hoechst and Propidium Iodide dyes.

Based on result, the percentage of matured oocyte is 66,67 KK ,66,67 KP1,70,73 KP2, and 82,50 KP3. Percentage viability of oocytes after vitrification is 82.14 KK, 87.50 KP1, 93.55 KP2, and 84.00 KP3. Percentage quality of oocytes after vitrification is 53,57 KK,54,17 KP1,58,06 KP2, and 24,00 KP3. The results showed that the addition of alpha tocopherol gave considerable influence on oocyte maturation rate, viability and quality after vitrification, although statistically did not show differences between treatments.

Addition of alpha tocopherol tends to increase maturation rates at higher concentrations 150 M and 200 M. Addition of alpha tocopherol at the maturation medium increase membrane stability, so the viability and quality of oocytes with the addition of alpha tocopherol 150 M after vitrification better than the control. Abnormality on oocytes after vitrification, the type of damage is divided into changes on oocyte shape, homogenity of cytoplasmic, integrity of cytoplasmic and degree of zona pellucida fracture. Fracture on zona pellucida becomes the most damaging damage affecting the viability and development of oocytes in the next stage, such as fertilization. The addition of alpha tocopherol 150 M antioxidants in maturation medium is a better concentration on maintaining viability and quality of oocytes after vitrification."
