Anyone ever used one of these?

For the dairy folks and/or beef folks with questions about udders, milk and mastitis.

never use that type of milker for any long term milking as it will damage the teats and can cause mastitis , milkers need pulsation to not cause damage , as the milk flows in the rest stage, you can build a milker using a surge belly milker and a vacuum source

here is some info, this was posted on Keeping a Family Cow

Evaluation of the Impact of Milking Machine Design on Teat
Swelling
William Gehm
LR Gehm, LLC
9502 NYS Rt. 79
Lisle, NY 13797
Abstract
A study was completed to evaluate the effect
milking machines have on teat condition of
dairy cows.

Modern milking machines extract milk from th
e dairy cow by applying a vacuum to the teat
creating a pressure difference that results in milk
flowing from the teat. Vacuum is applied by
placing the teat into a liner in
which the interior of the liner
is subjected to a vacuum. The
vacuum must be periodically reduced or remove
d to provide the teat with a rest period. The
rest period is required because the vacuum
causes the fluids (blood
and other fluids) to
accumulate in the teat causing congestion.
Modern conventional milking machines attempt
to provide this rest period by periodically
applying a higher pressure (atmospheric) to th
e exterior of the liner causing the liner to
collapse toward the teat. The typical convent
ional milking machine will thereby reduce the
vacuum level on the teat. The periodic liner
action created by the pulsi
ng of higher pressure
on the exterior of the liner
is provided by a pulsator.
There have been numerous published studies docu
menting the effect of this milking action on
the teat. A study published in the
Irish Veterinary Jour
nal (1) documents the damage inflicted
on the teat by this process when cows are milk
ed with typical modern milking machines. This
study evaluates the changes in th
e teat structure after being
milked with both conventional
wide and narrow bore liners and the associated
typical US style conventional pulsation anthe Irish DairyMaster style pulsation. The results
are reported using a teat damage index
defined as total teat
sinus injury (TSI).

Results included ultrasounding teats, slaughtering of some animals etc.

If one looks up "milk machine damage" or similar searches, you will find out why a milk machine works, what causes teat damage and mastitis and find out what you need in a milk machine to work. Milk machines work on pulsation - the inflations squeeze milk out like a hand would. They do NOT suck milk out - the machine showing is a milk sucker - it has a non collapsible inflation that is simply pulling vacuum on the teat which would cause swelling and congestion in the teats.

Anybody who wonders if this is true, should use a breast pump on themselves vs. a suction pump like used in the porn industry (or even a vacuum cleaner). The pump that simply pulls vacuum causes the most ridiculous swelling after not very long period of time, and just understanding how/ why a milk machine works should be enough information.

I would theorize that maybe if one could get a machine like the one built to release vacuum for a second every now and then that it could provide enough relief, but I don't know how it could be done safely in a way that would not involve the syringe falling off - inflation squeaking, slippage and improper vacuum interruption causes mastitis rather quickly (ask me how I know. . . ) so I have no idea how you would do that in a solid cylinder without losing vacuum around the teats in a way that could allow backflushing of milk etc. I also wonder how capable the machine shown is of maintaining 12lbs pressure - you do not want fluctuations and that machine has no pressure relief valve, and no way of sticking to 12lbs pressure without dropping up and down which is also well known for causing teat damage.

And in re. to experience, there was ONE member on here who built a unit like that and had supposedly used it without any problems for the 6-9 months they had been milking, but to me that is no indication that it is a system that is okay. I HATE dealing with mastitis, and teat damage problems are really hard to fix.

Not saying this person's dad isn't very inventive, just that some integral components are missing in the machine :) If simply sucking milk out worked, believe me, dairies would not have bothered with pulsators, rubber collapsible inflations, balance tanks, relief valves etc.

The one I posted has a pulsator...without pulsation you have nothing but a constant pull and get NO milk.

I had to milk a cow yesterday she must have been in pain her bag was so tight and the calf for some reason doesnt nurse that teat. She stood in the pasture and let me milk her never moved.
