Birthing knowledge. The birth process is broken down into three categories: preparation stage with relaxation of the pelvic ligaments, the delivery of the calf, and delivery of fetal membranes, also referred to as “cleaning.” During the calving phase several hormones including progesterone, estrogen, prolactin, relaxin and corticoids trigger the muscles of the uterus to contract and deliver the calf and membranes through the dilated cervix and vagina. Allowing your cows to calve in a clean environment and treating cows after a difficult calving will help prevent future reproductive problems.
