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 i nterval. In all cases, the animals received a CIDR 5 days prior to LOPU and were gonadotropin-stimulated starting at 72 h before LOPU using one of three protocols that were rotated twice among the animals during the study.
