Methionine beyond
protein synthesis in
growing pigs
Underestimating the importance of
methionine in swine nutrition can have a
huge economic impact; DL-HMTBA has
extra benefits for pigs in all growth phases.
BY YVES MERCIER AND
DOLORES I. BATONON-ALAVO

DL-HMTBA, one of the three sources of methionine
used in animal nutrition, improves milk composition.
fter lysine and threonine, total
sulfur amino acids (TSAA) are
the third limiting amino acids
in a pig's diet. Though it
is clear for poultry nutritionists that methionine
supplementation is indispensable, there is still a need to
clarify its importance in swine -

particularly during the growingfinishing period.

Methionine has been
shown to play a role in pigs
beyond protein synthesis.
In these latter phases, TSAA
requirement is generally met
through feedstuffs. However, de-

pending on the feed ingredient,
its origin or price, supplementary methionine may be needed
to meet requirements. These few
hundred grams per ton of feed
are sometimes neglected, resulting in a marginal deficiency,
which may impact economic
results. This demonstrates that
