Arachidonic acid is a bit more
difficult to encounter, and it might be
true it becomes semi-essential only
if the previous fatty acid is close to
its minimum 0.1% concentration.
Arachidonic acid abounds in animalderived ingredients, and the trend
toward banning or removing such
ingredients from a diet of an omnivorous animal such
as the pig may be the reason why we need to pay more
attention to this fatty acid.
Humans who eschew animal-derived food pay more attention to their arachidonic fatty acid intake, by consuming nuts,
algae, and other foods not easily found in animal nutrition.
Finally, omega-3 fatty acids and, of course, the most
important, conditionally essential linolenic acid, abound in
fish-derived components, especially from fatty-fish species.
Lamentably in pig nutrition, fish meal has become a luxury,
when it used to be an almost indispensable ingredient.
Luckily, a good source of omega-3 fatty acids is a landbased protein source in the name of linseed (flaxseed),
whereas more modern thinking is looking at (ancient) algae
as the next breakthrough in omega-3 nutrition for all animals.
Currently, animal products such as eggs enriched

with omega-3 fatty acids through the use of linseed oil
are considered very trendy among health-conscious
consumers. Again, there is uncertainty which and how
many of each of the many omega-3 fatty acids should be
consumed under each challenging condition, but nevertheless, given the present situation, the recommendation for
humans is certainly for rather more.
The same can be said for pigs, but here there is a greater
degree of uncertainty - and perhaps opportunity or
potential for loss - all of which can be addressed by more
research and, of course, end-user education.

Final recommendations
For now, I would keep the 0.1% linoleic recommendation as
the minimum dietary specification for all pig feeds, and I
would increase it up to 0.75% for breeding animals.
