I've done a little research, trying to figure this milker thing out.
I found this:
http://www.udderlybettermilk.com/health.htm, an anti conventional milking machine website, (they have a new and improved system to
sell) which documents some of the things that can go wrong in machine milking. Continuous suction is not good, too much suction is not good. What it does IMO, is disrupt the circulation in the tissue of the teat and udder, causing injuries at the cellular level, that never get a chance to heal. There are photos of deformed udders, and grotesquely deformed teats. These types of injuries and deformities appear to be quite commonplace, almost accepted in that line of dairying.
A good milker will provide a way to monitor the suction created, and somehow provide for the amount of suction to fluctuate, without the teat cup detaching from the teat.
And I found this:
http://pholiafarm.com/milk_and_milking.htm, a small Nigerian goat
dairy with
enough does that they use an electric milking machine. They talk about the pulsation feature on their milker, that's the term for the fluctuation in amount of suction. Now I know more about what I am looking for in a hand powered milking device.
They also talk about one of my other concerns, that my doe has very tiny teats. They have two sets of photographs of does at first freshening, and years later, the teats change in shape and size, as do udders, with successive lactation seasons. I guess I
should have been able to figure that out, having been through two lactation cycles myself. Things have never been the same.
They also have plans for a PVC built Nigerian milking stand. Looks like just what I need at a fraction of the cost and within my abilities and half the materials just lying around in the way.
So far, so good, but still plenty of research left before I buy any milkers.
