Eliminating excess udder hair significantly reduces the amount of mud and manure accumulating on the udder. This dirt can be a significant cause of environmental mastitis and milk contamination. Udder Singe uses a low-temperature butane flame to burn hair away in 1-2 seconds, without causing any pain or damage to udder or teats tissue. Singing of udder hair is common practice in the northern hemisphere. The Shoof Udder Singe is supplied complete with a 630ml canister of mixed gas. The wand is 75cm long with a plastic grip. The flame is controlled with an adjustable valve, to produce a 'lazy yellow flame' which will not burn the udder (This flame can be tested by running your hand through it). Extra gas is available from Shoof. Regular 'camping' type gas may cause malfunction of the wand. One can of gas should singe 300-400 cows.
