Mammalian sperm contains high proportion of polyunsaturated fatty acids which are sensitive to lipid peroxidation. Dietary fish oil can manipulate fatty acid profiles of reproductive tissues. On the other hand, vitamin E (VE) protects against oxidative damage. Fish oils have omega 3 and are a major source of eicosapentaenoic acid and docosahexaenoic acid. Many studies have evaluated the effect of fish oil supplementation on reproductive parameters in domestic animals. However, there are no studies specifically evaluating semen quality in dogs supplemented with fish oil. The objective of this experiment was to evaluate the effects of dietary supplementation with fish oil and VE on semen quality in dogs. In a 3x2 Latin square, five male dogs were randomly allocated into three groups and fed a control diet (C), a control diet supplemented with 54 mg fish oil/Kg metabolic body weight (FO) or same diet and supplement plus 400 mg VE for 60 days (FOE). Semen samples were collected on days 0, 30 and 60 and their characteristics evaluated by standard methods. Data were analysed using a mixed model with repeated measures (SAS 9.0). In the FO and FOE groups the percentage of sperm motility (P=0.02), total sperm count (P
