119 Change in Serum Total Lipid Profiles in Dogs Supplemented with Camelina, Flaxseed, or Canola oil for 16 Weeks

Abstract There are few data describing the effects of different oils on fatty acid (FA) metabolism in dogs. Our objectives were to assess camelina (CAM), flaxseed (FLAX), and canola oil (OLA) serum total lipid FA profiles over a 16-week feeding study. Thirty healthy, adult dogs various breeds [17 females, 13 males; 7.2±3.1 years 27.4±14.0 kg (mean±SD)] underwent 4-week dietary wash-in period commercial, low-fat kibble top dressed with 8.2g sunflower oil/100g food intake. Dogs blocked by breed, age, size, assigned receive CAM, FLAX, or OLA for 16-weeks at same dose as wash-in. Serum measured using gas chromatography from baseline week 16. Data analyzed ANOVA PROC GLIMMIX SAS. In all treatments, final percent area pooled individual omega-3 (n-3) omega-6 (n-6) FAs inversely related, n-3 being greater 16 n-6 less compared (p< 0.05). Conversely, dihomo-γ-linolenic showed accumulation docosahexaenoic was than treatments Stearidonic FLAX but both similar α-linolenic differed among (FLAX >CAM >OLA) Eicosadienoic CAM Omega-9 Eicosaenoic mead OLA, oleic Differences fed camelina, flax, due inherent concentrations suggest suitable increasing concentrations.
