Food-providing animals for providing human food rich in at least one of
the health-promoting n-3 HUFAs (omega-3 highly unsaturated fatty acids)
are selected and then bred so that a greater proportion of dietary n-3
HUFAs and/or their metabolic precursors provided to the animals is
conserved in the animals food tissue as n-3 HUFA and transferred into
human food. Evidence of heritability, methods for phenotypic or genotypic
identification and selection of animals genetically adapted for that
function are provided. Animals include farmed mammals and birds, and
marine or fresh water animals including fish, crustaceans and molluscs.
