Means of ovulations, proportions of transferable embryos and recipient pregnancy were calculated from individual donors and analyzed by analysis of GLM. One factor was analyzed each time using the univariate module, and variables were compared with LSD. Results are presented as the mean±SE. Proportions of does in estrus, with cystic ovaries and with adhesive tracts, and the parturition rate of recipients and the kidding rate calculated from embryos were analyzed by Chi-square test (SPSS, Inc.
