A good cow doesnāt kick! PERIOD.
If you need to put a clamp or any other anti- kick device it tells me one of two things;
A) you aināt a cow person and should leave the milking to someone who is.
B ) that cow has been abused and is defensive which means sheās nervous and wonāt let her milk down.
Full disclaimer- sometimes you need these devices such as a new heifer being milked for the first time, or an injury to the cow/udder/teat. But to use these devices for every milking, then that cow needs to go, or the person doing the milking needs to go.
IN MY OPINION from 30 years of milking cowsā¦.
When I bought my first herd of cows, (a lifetime ago) I think half of them had a broken tail from āmilker abuseā Some people shouldnāt be allowed around livestock.
