ABSTRACT
A total of 33 nonsurgical embryo collections was carried out to investigate early embryo development in Thai swamp buffalo. Collections were performed on Days 5.5, 6.0, 6.5, 7.0 and 7.5. The different stages of embryo development on these days were the 16-cell stage, compact morula, blastocyst, hatched blastocyst and hatched expanding blastocyst, respectively. In addition, some degenerating embryos and unfertilized ova were also recovered. A higher recovery rate was obtained with single embryo collection after natural estrus than after induced estrus or superovulation, 78% (7 9 ) vs 46% (6 13 ) vs 54.5% (6 11 ), respectively. A higher percentage of normal embryos was also obtained with single embryo collection after either natural or induced estrus than after superovulation, 71% (5 7 ), 83% (5 6 ) and 38% (6 16 ), respectively.
