How to blow a cow

Found out 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 a link to the video, go to it if you wish:
