In free-ranging wild animal farms, such as deer farms, good animal health is crucial to reach production goals. These animals are affected by both gastrointestinal and thoracic parasites, as well as external parasites.

Furthermore, consuming contaminated grass from pastures, an unbalanced diet, and heat stress can compromise the immune system of the animals and set the stage for infectious and metabolic diseases. Investing in a healthy diet will prevent most of the common diseases like tuberculosis, leptospirosis (a kidneys disease that causes weight loss and abortion), yersiniosis (an acute inflammation of the intestines), facial eczema (caused by spores that damage bile ducts and the liver), and other bacterial and viral diseases that can cause great losses and limit production.
