Udder hair remover

from Wikipedia, the free encyclopedia
Slightly hairy udder of a dairy cow

An udder hair remover is a device that is used to remove udder hair from dairy cows . The term cold flame is often used because of the reduced temperature .

Procedure

The udder hair remover is a modified gas burner in which the hair on the udder of dairy cows is scorched with a temperature-reduced gas flame . According to veterinary studies, there is a significant correlation between the depilation of udder hair and the cleanliness of the teats . Hairy udders are more difficult to milk and clean, and stay moist longer. In the case of milking robots in particular, hair removal is recommended for better teat detection. In addition, germs or contamination with the hair can get into the sockets during automatic milking and thus infect the milk with germs. This creates a higher risk of soiling, especially in winter. The removal of the udder hair is also used for disinfection and is intended to reduce widespread diseases such as mastitis and John's disease .

Technical implementation

The udder burner is a gas burner with which the udder hair is removed from a curved lance by singeing it with a yellow gas flame at a maximum temperature of 200 degrees Celsius . The flame has a much larger expansion than with conventional weed killers. The oxygen supply is reduced in order to avoid temperature peaks. The hair is singeing mostly every 4–5 weeks and only takes a few seconds per cow. Among other things, it is recommended to moisten the teats before singeing.

After the scorching is finished , it is recommended to remove the ashed hair by hand or with a brush and to apply cream to the cow's udders. As long as the cows do not see the flame, they are hardly frightened when it flames . When shaving their udders with electric hair clippers, which was common in the past, the cows became much more worried. In addition, in some herds it was too difficult or risky to approach the animals with the clippers and to cut the hair mechanically.

history

The regular removal of udder hair was recommended in parallel to the fashion of body hair removal in humans as early as the middle of the 20th century in the USA and from there came to Central Europe.
