A device that assists in the delivery of a calf.

What is a calf jack?

Over the hips of the cow.

Where is the strap of the calf jack placed?

They are attached to the legs of the calf and to the ratchet on the shaft of the calf jack.

What are OB chains used for in a calf jack?

It aids in pulling a calf out when used appropriately with the contractions of the cow.

What is the function of the ratchet in a calf jack?

It should be used at the correct angles and in conjunction with the contractions of the cow.
