Enhanced omega-3 index after long- versus short-chain omega-3 fatty acid supplementation in dogs.

The results showed that supplementation of AKO from Antarctic krill led to a significant increase in the Omega-3 Index in comparison to FSO in dogs. This suggests that preformed marine EPA and DHA sources are needed in dog feeds, as the dietary requirements proposed by feed industry organizations are not met with conversion from short-chain n-3 fatty acids.
