Difficulties with Calving

Dystocia difficult birth, typically caused by a

large or awkwardly positioned fetus, by smallness of the maternal pelvis, or by failure of the uterus and cervix to contract and expand normally.

should be on the ground

Problems with the calf

Problems with Mom

Torsion• The twisting of the uterus,

therefore not allowing the calf to pass.

• The solution is untwisting the uterus. Which requires a phone call to your local large animal vet.

Time to get the calf out.

Step 1: get the chains properly positioned around front legs.

Step 2: Offset the shoulders and pull

Discussion Activity:

- As soon as you have the chains on, do you just yank the calf out?

- Discuss with those around you what you might think the next step would be upon placing the pull chains on the calf.
