There is also the possibility of infectious agents in the birth canal that can affect people, so wear sleeves. Check the vulva to see if it is relaxed and large enough for delivery. The vagina should be examined for obstructions like fat, a pelvic fracture, abrasions, or bleeding. The cervix should be examined to assess the degree of relaxation and dilation. The next step is to determine the position of the calf.
Presentation is important for a successful delivery.
You should examine all the way up to the elbow or hock. If two feet are presented, it is important to determine if they are both front or rear feet, or a combination of each. Forced extraction or delivery by mechanical means is very critical. Calf chains are preferred over ropes. The chains should be positioned in two areas, a loop above the fetlock and a half-hitch below the fetlock.
