Comparative analysis of cryopreservation oocyte-cumulus complexes piggy-wiggies of different breeds
The results of experimental researches are demonstreted from the estimation of viability frozen-thawed oocyte-cumulus complexes piggy-wiggies of breed large white and landrace with the use of modern biotechnological methods. The comparative analysis of impregnating ability frozen-thawed gametes piggy-wiggies of both breeds and morphological and сytogenetic estimation of got in vitro embryos pigs is conducted. It is set that fertilization frozen-thawed ovules of piggy-wiggies of breed large white native sperm of hogs of breed landrace results in diminishing on 12,3 % the amounts of the got embryos are compared to the fertilization of gamete piggy-wiggies of breed landrace. Certainly dynamics of forming in vitro embryos pigs breeds large white and landrace, which are got from frozen-thawed ovules after the impregnation hogs of breed landrace sperm.
