Teat-Mate, made by Jaychem in Auckland, is being sold through RD1, Farmlands, and on the internet. A concentrate, it is marketed in 20-litre, 200-litre and 1000-litre containers costing $270, $1667 and $6854 respectively. The national market for teat sprays is understood to be worth millions of dollars annually and Teat-Mate has potential for sales around the world.
A once-a-day milker, Lethbridge wanted a teat spray that would last for 24 hours and heal dry cracks and low-grade infections.
He knew saline solution had anti-microbial properties and asked the Hawkens if it could form the basis of a new teat spray.
They came up with the glycerine mix and when the Lethbridges and their neighbours tested it extensively the product appeared to be a winner.
Aloe vera was added later, Lethbridge said.
"It was mentioned as a magic word for healing -- and it worked."
The product has been patented in New Zealand and Australia.
