Results are in from the Equine Guelph funded research that marks the first study to investigate steamed, soaked and dry hay in Ontario. Tiana Owens, a University of Guelph graduate student involved in the study, presented these results during her thesis defence last month. The research team, which also includes Madeline Barnes, Vanessa Gargano, Wilfredo D. Mansilla, Katrina Merkies and Anna K. Shoveller, found that steaming hay may be a superior method for treating hay when it’s being used to feed healthy performance horses.
The researchers compared nutrient content, feed preference, and glycemic response between dry, soaked and steamed timothy-alfalfa hay grown in Ontario. Standardbred racehorses were used in the study for researchers to examine which hay treatment may be most suitable for performance horses. Owens explains, “Horse caregivers often soak or steam hay to reduce its non-structural carbohydrate (NCS), including water soluble carbohydrates (WSCs). A high dietary intake of these carbohydrates can be detrimental to some horses.” However, these practices are based on research from the United Kingdom, so information on Ontario hay was needed.
