Herbal Products are used for health and medical functions since ancient times. Plants and their extracts are also well-known phytobiotics or phytogenics that are widely used in animal traditional and alternative medicine. In recent years the use of herbal/plant medicine is increased in livestock production due to the side effects of modern drugs, the high input costs, toxic residues in food, microbial resistance and due to the development of organic livestock production systems. Plants are used as health promoters and also for the treatment of diseases.
