Many studies have been made on feeding supplements that contain plant extracts and their application in pig diets is an area of rapid development.
Studies not only looked at improved digestion through the use of plant extracts. Also, sow and litter performance can improve by adding phytogenic substances to the feed.
Combining organic acids with their salts with phytogenics also seem to have promising effects. These mixtures are user-friendly and have been shown to produce a synergetic effect on digestion, mainly in the stomach.
