Our Smart Zero Range was inspired by our Danish distributor and is formulated using the highest quality ingredients to support work, performance and condition, with minimal starch and sugar levels. As the name would suggest, our Smart Zero feeds have Zero Molasses and Zero whole cereals to help achieve this aim.

Designed to provide quality nutrition to horses and ponies with metabolic / endocrinal conditions, or those at risk from gastric ulcers, the low sugar and starch formulations in Smart Zero provide the levels of energy and supporting micronutrients required for performance and to maintain or gain weight and condition.

Castle Smart Zero feeds are extremely versatile and provide a healthier option for all active horses and ponies, including competition, sport horses, and veterans.
