Coated additives We have combined our extensive knowledge of fluidised bed technology and fat processing to upgrade feed additives with a fat coating. This ensures the stability of the additive for an extended period, prevents premature release and enables targeted nutritional supplementation. The possibilities range from rumen-stable coatings (e.g. amino acids for milk cows) to smell and taste-masking for sensitive animals (e.g. butyric acid preparations for piglets) to time-controlled release in the digestive tract (e.g. slow-release urea for cows).
