Comparative Evaluation of Domestic Hot-air-Dried Italian Ryegrass and Imported Timothy Hay as Forage Sources for Riding Horses: Effects on Body Condition and Blood Biochemical Profile

Key Points

• This research aims to compare the effects of domestic Italian ryegrass and imported timothy hay on the body condition and biochemical profiles of riding horses.
• Assigned 10 thoroughbred horses to two groups: one fed Italian ryegrass and the other fed timothy hay.
• Each group was fed their respective forage for 12 weeks.
• Monitored body condition scores and blood biochemical levels over the trial period.
• No significant differences in weight and body condition index between the two groups.
• The group fed Italian ryegrass showed a slight increase in withers height and weight despite rising summer temperatures.
• Blood metabolite concentrations varied but showed no significant differences between treatment groups.
