Interval of gonadotropin administration for in vitro embryo production from oocytes collected from Holstein calves between 2 and 6 months of age by repeated laparoscopy

In this study, 11 Holstein calves were subjected to up to six LOPU procedures between the ages of 2-6 months at 2-3 weeks interval. In all cases, the animals received a CIDR 5 days prior to LOPU and were gonadotropin-stimulated starting at 72h before LOPU using one of three protocols that were rotated twice among the animals during the study.
