Imflammatory response in horses fed diets containing omega-6 and omega-3 fatty acids
MetadataShow full item record
This study was conducted to characterize the inflammatory response of horses to chronic and acute exercise as influenced by dietary fat supplementation. Different ratios of omega 6 vs. omega 3 fatty acid supplementation were provided in the diets and effects on the inflammatory response were determined. Nine, three and four-year-old horses were fed diets with different sources of fat in a triplicated 3X3 Latin square arrangement of diet treatments. The horses were maintained in a typical reined cowhorse training protocol to mimic the athletic stresses placed on young horses during strenuous exercise. There was no significant difference (P>.05) in body weight between horses consuming the three diets. When compared to consuming diet B (corn oil) and C (soybean oil) the horses fed diet A (control) had higher (P<.05) concentrate intakes, and total feed intake was higher (P<.05) for horses fed diet A than diet B. Horses fed diet A had higher (P<.05) digested dry matter and digested organic matter than horses fed diet B. There were no differences (P>.05) in dry matter digestibility or organic matter digestibility between horses fed the three diets. Fat intakes and digestibilities were higher (P<.05) when the horses where fed diet B and diet C than when fed diet A. When the horses where fed diet A they had higher (P<.05) concentrations and percent change in 14:0, 16:0 and 18:1n-9 fatty acids at d 32. When the horses were fed diets B and C they had higher (P<.05) concentrations and percent change in 18:2n-6. When the horses where fed diet A (P<.05) they had lower concentrations and percent change in 20:4n-3 than when horses were fed diet B. Overall mean fibrinogen concentrations across treatments increased (P<.05) during the training period. When analyzed by diet, fibrinogen concentrations during the training period and following the standardized exercise test were higher (P<.05) when the horses were fed diet B than when they were fed diets A or C. Overall mean serum amyloid A concentrations across treatments increased (P<.05) from the day of the test to 1 day following the standardized exercise test and then decreased to baseline values at d 3 post test.
