Context

Mastitis is currently the most common and the most worrying disease in the dairy cattle sector, as it represents almost 40% of all cow disease, being the main cause of economic losses, in both farms and the industry as a whole. In terms of production, these losses can represent up to 60-70% of total farm losses.
The main factor causing mastitis is poor hygiene during the milking phase. For this reason, it was decided to maximise hygiene of the teats in this phase. So far, the sanitisation and disinfection technique has been carried out using chemical products, especially from the iodophor group. The main problem is this increases the iodine content in the end product. There is a positive correlation between the increase in iodine content in milk and the use of iodine preparations pre- and post-dipping.
Thus, a strategy is required to reduce the source of iodine in milk and avoid disrupting the welfare of the cattle. This project consisted of carrying out experiments based on the use of electrolysed water to control mastitis, determining the technical and economic feasibility of using it as a sanitising and disinfectant agent for teats during milking, as a substitute for chemical products such as iodophors.
