HOCl has been trialed by researchers at the Royal Veterinary College (University of London) on a UK farm with 735 dairy cows. 350 were lame. This was a zero graze herd, with slurry providing perfect conditions for Bacillus necrophorus. Infected lesions were washed twice a day with a solution of Aqualution® hypochlorous acid (HOCl), while the cows were being milked. After three weeks, there were no lame cows at all.
We are also partnering one of the main equipment suppliers to the dairy industry, to develop an automatic system that washes the cows’ feet as they go into the milking parlour. Each cow receives separate solution, and there’s no cross-contamination.
This is a vast improvement on copper sulphate, which is being withdrawn, and on formaldehyde which, as well as being corrosive and toxic, stings the animals, exacerbating the slurry problem, and quickly becomes inactive. Aqualution® is safe for both animals and humans, and requires no special handling procedures.
