Effect of different concentration of Oxamflatin on the development of cloned bovine embryos in vitro.

Four replicate experiments were performed per treatment. Numbers in parentheses represent development rates (mean ± SEM%), while other numbers represent total embryo numbers of four replicates. Development rates of 2-cell embryos, 4-cell embryos, morulas, and blastocysts were monitored at 48, 72, 120, and 168 h of culture, respectively (0 h being the time embryos were transferred to G1.3).Within a column, developmental rates with different superscripts are significantly different from each other (P
