Effect of Feeding a DHA-Enriched Nutriceutical on Motion Characteristics of Cooled and Frozen Stallion Semen

Source: S. P. Brinsko, D. D. Varner, C. C. Love, T. L. Blanchard, B. C. Day and M. E. Wilson Elevating the level of specific omega-3 fatty acids in equine semen by dietary modification can improve motion characteristics of cooled-stored and frozen-thawed sperm. Stallions, which produce semen that has poor tolerance to cooling and freezing, […]

The Effect of Dietary Fish Oil Supplementation on Exercising Horses

Horses were assigned to either a fish […]

Fish Oil Supplementation Reduces Severity of Exercise-Induced Bronchoconstriction in Elite Athletes

Source: Timothy D. Mickleborough, Rachael L. Murray, Alina A. Ionescu, and Martin R. Lindley In elite athletes, exercise-induced bronchoconstriction (EIB) may respond to dietary modification, thereby reducing the need for pharmacologic treatment. Ten elite athletes with EIB and 10 elite athletes without EIB (control subjects) participated in a randomized, double-blind crossover study. Subjects entered the […]

Effects of the Omega-3 Fatty Acid, a-Linolenic Acid, on Lipopolysaccharide-Challenged Synovial Explants from Horses

Weisbrode To determine the effects of pretreatment with α-linolenic acid, an omega-3 polyunsaturated fatty acid, on equine synovial explants challenged with lipopolysaccharide (LPS). Animals-8 mature mixed-breed horses (4mares and 4 geldings). Procedure-Synovial explants were assigned to receive 1 of 7 concentrations of α-linolenic […]

Effect of Intravenous Infusion of Omega-3 and Omega-6 Lipid Emulsions on Equine Monocyte Fatty Acid Composition and Inflammatory Mediator Production In Vitro

Source: M. E. McCann, J. N. Moore, J. B. Carrick, M. H. Barton The effect of intravenous administration of lipid emulsions enriched with omega-3 (n3) and omega-6 (n6) fatty acids on equine monocyte phospholipid fatty acid composition and the synthesis of inflammatory mediators in vitro was evaluated. In a randomized crossover design, horses were infused […]

Dietary Long Chain Polyunsaturated Fatty Acids Increase Plasma Eicosapentaenoic Acid and Docosahexaenoic Acid Concentrations and Trot Stride Length in Horses

Source: A. D. Woodward, B. D. Nielsen, C. I. O’Connor, S. K. Webel, and M.W. Orth It has been reported previously that fish oil causes beneficial effects not only the circulation system, but also in problems arising from osteoarthritis. However, benefits associated with supplementing fish oil are overruled by palatability issues. Therefore, a stabilized long […]

Alteration in the Inflammatory Response in Athletic Horses Fed Diets Containing Omega-3 Polyunsaturated Fatty Acids

Source: K.R. Wilson, G.D. Potter, E.M. Michael, P.G. Gibbs, D.M. Hood and B.D. Scott The inflammatory response in athletically challenged horses is poorly understood. Further, effects of feeding diets with differing polyunsaturated fatty acid (PUFA) profiles on the inflammatory response is not clear. This study was conducted to characterize the inflammatory response of horses to […]

Fatty Acid Profiles from Red Blood Cells in Response to Three Levels of Dietaray Omega-3 Fatty Acid Supplementation

Source: SS King, KL Jones, GA Apgar, A AbuGhazaleh Omega-3 fatty acids confer various cardiovascular benefits, improved insulin sensitivity and immune function and even fertility enhancement. Omega-3 fatty acids may be incorporated into membrane lipids to influence its structural micro-environment or act as a fatty acid reservoir for the body. The present study sought to […]

Essential Fatty Acid Supplementation as a Preventative for Carbohydrate Overload-Induced Laminitis

Source: Kelly A. Neelley, DVM and Douglas J. Herthel, DVM Essential fatty acid supplementation prevents laminitis in horses challenged with carbohydrate overload. Possible mechanisms that would explain these findings include the known effects that essential fatty acids have on inflammation, vasoconstriction, hypertension, and coagulation in laboratory animals and man.

Effects of Dietary Fish Oil and Flaxseed on Plasma Fatty Acid Composition and Immune Response in Yearling Horses

Source: K.R. Vineyard, L.K. Warren, K. A. Skjolaas, J.E. Minton, and J. Kivipelto Feeding fat to horses has become a common practice in the horse industry over the past decade. One of the most common reasons for supplementing fat is to increase the energy content of the ration. Other benefits to feeding a fat-added diet […]
