Understanding Your Market Needs

Disinfection is a natural solution to hygiene problems. Carmeuse has created the OPTILIT® product range to naturally disinfect your barns or poultry halls. Thanks to the high pH of these products, parasites cannot develop as quickly as they do at low pH. OPTILIT® products contain calcium components, which can be reused later as soil amendment when combined with organic manure. Our experts can recommend the most appropriate solution for your barn and animals.

Cattle hygiene is a key factor for the health of these animals and thus the profitability of your farm.

  • Humidity, heat and manure on the ground foster the development of bacteria.

    • Less milk production.
    • A shift in the lactation period.
    • Less weight gain during fattening of meat cows and young bulls.
