K+S Minerals and Agriculture GmbH presents findings from a practical research project in animal nutrition, conducted in collaboration with Osnabrück University of Applied Sciences. The focus is on feeding trials related to magnesium supplementation in broiler rearing. The studies show that magnesium sources with higher bioavailability not only have positive effects on meat quality but can also improve feed efficiency. The findings are based on practical trials carried out under commercial farming conditions, addressing key challenges of modern and efficient animal production.
