Abstract


Reproduction technology achievement on caninew as fastd eveloped, with born of cloning and transgenic dog, unforfunately that's technology still used oocyte matured in vivo because canine oocyte matwation in vitro
in this animaln ot developedy et and mafurationr ates till low. The present study was to investigated the effects of cow serum supplementation on meiotic resumption of canine oocytes from various estms stage. Ovary obtained from bitchesa tan-, pro-and di-estrus stage after ovariohysterectomizeadt clinic veterinarypracticeO. varyw ere

Selected cummulus oocyte complexes (COCs) were matured in TCM-199 as control and TCM-199 + 10% cow serum as treatment, on incubator with 38C, 5% CO2, and 5% O2. After 72 h incubation and Hoechst 33342 staining, the result shows that cow serum supplement have higher meiotic resumption significantly (P<0.05) in MI achievement han in control and oocyte from proestrusi rave higher meiotic competent(46.5%) comparing oocyte from anestrus(29,4%)s ignificantly(P<0.05) but not significantly(P>0.05) with diestrus stages(34.8%).
