We started using Nadins Hydramix during the Christmas week of 2014, up until this point we were getting 2 cases of mastitis per week, in the following 5 weeks we had no cases, with continued use it has helped to keep cases of mastitis down. We have found it a heavier product than hydrated lime which means when we spread it indoors in windy conditions with the fans going etc it does not blow around, this improves working conditions.  I have now changed farm and am encouraging them to change from hydrate lime to Nadins Hydramix.
