Abstract:

from the many years of transfer records of embryos produced in vitro at the genetics center in the municipality of san pedro de los milagros, antioquia, colombia, we examined retrospectively if there was a relationship between the number of viable oocytes and embryos produced by the donors. depending on the race, we sought to determine whether there is an influence by the donor. the variables analyzed were: the bull, race, batch, and reproductive history of the donors, all of which were in similar health and nutritional conditions. the evaluation of the results was carried out with the chi-square test statistical model. in order to compare between the percentage of viable oocytes and the percentage of embryos, an analysis of variance (anova) was performed as well as a fischer test, with a confidence interval of 95% and a p-value of p>0.05. statistically significant differences were found in the production of embryos (40% vs 29%) taurus and indicus, respectively. the conclusion is that taurus donors produce greater numbers of embryos than indicus donors.
