Calprona Performance Enhancers are used to increase the energy uptake (to prevent grass tetany and ketosis in cows) and to increase milk-fat content. Calprona Mineral Supplements are essential nutrients and are used to reduce stress (and stress related injuries) for example after regrouping or transport of pigs and poultry. Calprona feed preservatives prevent spoilage by recontamination of the feed, maintain the nutritional value of the feed (resulting in higher feed efficiency) and act as an additional source of minerals and energy.
