Fertilitas Dan Persentase Embrio Kerbau Sampai Morula Yang Dikultur Dengan Penambahan Glutathione Secara in Vitro

The concentration of high fat content in buffalo embryo culture media is very influential on the increase in oxidative stress that occurs in conditions of in vitro. The occurrence of increased oxidative stress in the process of embryo culture in vitro, would result in lower percentage of embryo culture until the morula stage (32) cells. The purpose of this study was to determine the percentage of fertilized oocytes supplemented with glutathione. To know the development of the embryo until the morula stage (32) cells were cultured in the culture medium supplemented with glutathione (GSH). To determine the viability of morula stage embryo or 32 cells. The materials used in this study is ovarian buffaloes and methods used in this study is an experimental method in the laboratory. Based on these results it can be concluded that the addition of glutathione 1.5 mM in media oocyte maturation buffalo in vitro provide a significant influence on the percentage of maturation ie (P <0:01) or 62.5% and in line with the high percentage of oocytes matured in treatment increase glutathione 1.5 mM, then the percentage of oocytes were successfully fertilized also higher, namely 88.98%. Furthermore, the addition of 3 mM glutathione in embryo culture media in vitro buffalo give a significant influence on the percentage of embryo development to the morula stage or cell 32, namely (P <0.01) in, or 40.73%

Kualitas Spermatozoa Epididimis Kambing Kacang dalam Bahan Pengencer Tris Kuning Telur pada Suhu 5°C

The purpose of this study was to observe the quality of the epididymal spermatozoa of the Kacang goats which were preserved at 5°C. Spermatozoa are taken from epididymal of Kacang goats in Payakumbuh City Slaughterhouse for 10 pairs and collected with a combination of the slicing method and suppression of the epididymal canal. The parameters observed were the percentage of progressive motility, live sperm and abnormalities. The data analyzed by Analysis of Variance in the form of a randomized block design with four treatments and six replications of the retrieval days as a group. The results showed that the percentage of progressive motility of epididymal spermatozoa after preservation of 0, 1, 2 and 3 hours was not significant (P>0.05). Furthermore, the percentage of life has a very significant effect (P0.05). It can be concluded that the effect of preservation of different cauda epididymal semen at a temperature of 5°C has not been optimal yet in improving the quality of epididymal spermatozoa of Kacang goats
