Proper Preparations Before Pulling Calves Crucial to Positive Outcomes, Selk Says

Glenn Selk, Oklahoma State University Emeritus Extension Animal Scientist writes in the latest issue of the Cow-Calf newsletter that as calving season unfolds, preparations for a difficult births are a must.
The fall-calving season is underway. Before applying the obstetrical chains to "pull" a calf during a difficult birth, a proper analysis of the situation must be made. Wash the vulva, anus and the area in between using soap and warm water. Pulling on a calf should only be done when the presentation and posture of the calf are normal. Normal is defined as the "anterior presentation" with front feet first, head resting on the limbs, and the eyes level with the knees. A backwards calf can be delivered only when both back limbs are presented. Before chains are applied, be certain that the cervix is completely dilated. Know your limitations. If you examine the cow or heifer and find it is going to be a more difficult task than you can handle within a short time, call your local large animal veterinarian as soon as possible.
To properly use obstetrical chains when assisting with a difficult birth, follow this procedure. To attach the chain, loop it around the thin part of the leg above the fetlock. Then, make a half hitch and tighten it below the joint and above the foot. Make certain that the chain is positioned in such a manner that is goes over the top of the toes. In this way the pressure is applied so as to pull the sharp points of the calves' hooves away from the soft tissue of the vaginal wall.
