People were aware of some "let-down" process long before hormones were known. All kinds of gimmicks and props and rituals have been used to bring it on strong. For thousands of years it was suggested the calf had to be present at milking time. If you didn't have a live calf a stuffed one might do. Or the milker would don a calf skin.
Then there was (and still is in some parts of the world) a practice of insulflation to encourage let-down. While one person milked another blew air or water into the cow's rectum.
I explained all this to the owner of our local feed store. He said he wouldn't want to be the one blowing the air. I pointed to my son and commented, "What do you think he's for?"
More office work this morning (Requiem Press still lives in a weak economy), but later if the rain holds up, I will work on some chicken/turkey housing and possibly process a couple roosters who have come of age.
Oh yes, and we have a game hen sitting on some fertile eggs. A couple more weeks and we will have some totally free-range chicks floating around.
Oremus pro invicem!
