The objective of this study was to compare the de\eIopmentai ability of embryos in 4 different media, CR I aa,
modified CR2, BCEM-g and TCM-199. Bovine oocytes were matured and then fertilized in vitro. A total of915 oocytes
were used for fertilizatiqn, 681 (74%) of which/cleaved, The 2-cell embryos were divided into 4 groups, and cultured in
I of the 4 different culture media. Percentage of development to morula-blastocyst stage from the 2 cell stage were
determined as 46. 31,30 and 28% for CRI aa, CR2, BCEM-g and TCM-I99 culture media respectively. The development
rate obtained with CR I aa was significantly'higher (P<O.O I) compared to that with the other media.
