We have a member here that goes by cowdoc so he could advise you about the mechanics of bovine birth but if I had any cows at all I would own a calf puller. The first calf you save will pay for it not to mention saving a cow. The downward pull seems to do far less damage than a straight out pull. As I said learn how to operate the thing and know where it is at all times. All it costs is the original price and will last forever if kept under a roof. My neighbor and I got so good at it that all the cow people around were calling us.

Patriotism (and religion) is the last refuge of a scoundrel.
