How to blow a cow

I learned about this subject matter from a recent podcast of No Such Thing as a Fish:

Cow blowing, Kuhblasen, phooka, or doom dev, is a process used in many countries according to ethnographers, in which forceful blowing of air into a cow's vagina (or sometimes anus) is applied to induce her to produce more milk.

Cow blowing was the reason why Gandhi abjured cow milk, saying that "since I had come to know that the cow and the buffalo were subjected to the process of phooka, I had conceived a strong disgust for milk."

A brief search yielded a video of the process.   Frankly, I don't find the maneuver any more disgusting than American presidential politics, but in recognition of the more refined sensibilities of some of this blog's readers, I'll place the video below the fold:
