Complementary feedingstuff for horses
The wild ancestors of our modern-day companion horse fed on a large variety plants in their habitat. Grasses and herbs grew in soil that was not exploited by intense agriculture nor damaged by environmental influences.
If we pursue the aim of feeding our pets species appropriately, and therefore healthy, it is not entirely possible to do this by administering industrially acquired feed raw materials and by adding some minerals. The many herbal ingredients which a herbivore living in the wild consumes cannot be replaced by anything other than the largest possible selection of these herbs.
