Raw materials are defined as: materials which are used to make or fabricate something. Tromp utilizes trace elements (such as copper sulfate, zinc oxide), feed materials (such as lime, salt, magnesium oxide) and vitamins for the mixtures, plus several other raw materials, as supplements to the animal feeds. Usually, it involves extra additives which the animals originally would find in the wild, but which are now in deficit in their changed lifestyle. Sometimes we can add the exact same natural ingredients; often we try to find creative solutions using ingredients with the same qualities. It’s always about a healthy balance. Tromp adjusts compositions only after substantial research. The most important thing is in the practice. We gladly listen to your experiences and ideas in order to support you in further optimizing your business.
