Abstract:Twelve mature and six 2-year-old Arabian horses were used to determine the effect of dietary long-chain polyunsaturated omega-3 fatty acid supplementation on fatty acids, bone markers, and lameness. Stride lengths at the walk and trot, lameness scores, and range of motion of leg joints were measured on d 0 before horses were pair-matched and fed either a treatment diet (FA) containing stabilized omega-3 fatty acids or a control diet (CO) containing corn oil for 75 d. Horses were exercised 5 d/wk, and blood samples were drawn and body weights recorded on d 0, 25, 50, and 75. Stride lengths, lameness exams, and range of motion were recorded again on d 75. Total omega-3 fatty acid concentrations were higher in FA horses than CO horses. Total omega-6 fatty acids increased from d 0 to d 25 before returning to baseline on d 75 in all horses. The ratio of omega-6:omega-3 fatty acids was lower in FA horses. Plasma EPA concentrations tended to increase over time in FA horses. FA horses had increased plasma DHA on d 25, d 50, and d 75. There was no difference in walk stride length; however, FA horses tended to have a longer trot stride after supplementation. There were no differences in osteocalcin, ICTP, PGE2, or TNF-α. Supplementing omega-3 fatty acids increases EPA and DHA, while a trend to increase trot stride length indicates a possible decline in joint pain associated with arthritis, potentially by inhibiting inflammatory pathways.
