Effect of dietary polyunsaturated fatty acid and related nutrients on plasma lipids, and skin and hair coat condition in canines
Blood samples were collected on d 0, 5, 8, 16, 28, 56, and 84. Profiles of plasma phospholipid fatty acids were determined at each collection period. Serum zinc concentrations were analyzed on wk 12, 14, and 24. The hypothesis was that a diet containing increased LA, ALA, and zinc concentrations (diet C) would show improvements of skin and hair coat condition in dogs compared to the other diets. All three test diets caused significant improvements compared to Ol'Roy[trademark]. Diet B caused more improvement than diet A in both subjective and objective assessments of skin and hair coat. Based on mean values diet B is better to be fed to dogs that need to improve skin hydration and diet C should be fed to dogs that need to decrease TEWL. Diet C not only led to improvements in skin and hair coat condition, but also provided additional benefit by producing less pro-inflammatory conditions in the skin.
