The transfer of n−3 fatty acid from feed to meat is difficult to
achieve in ruminants as outlined above. Still there have been some
promising attempts to at least improve the n−6:n−3 ratio, as n−6
fatty acids are biohydrogenated as intensively as the n−3 fatty acids.
A number of studies have demonstrated that the n−3 fatty acid content
in meat lipids is higher in grass-based compared to forage-based
diets and that the n−6:n−3 ratio is beneficially low in ruminant
meat when animals have consumed grass (reviewed by Morgan,
Huws, & Scollan, 2012; Scollan et al., 2006).
