Sometimes horses can be sensitive to the quality of air they breathe. The presence of dust, mould or pollen can cause respiratory disturbances. Audevard Balsamic Control is a complementary feed specially designed to contribute to the respiratory needs of horses living in dusty environments. It is also suitable for young racehorses in training. It contains a unique combination with nigella, lemon, eucalyptus and garlic. In addition, it contains no substances that would cause a positive doping test.
