In that study,
supplementing much more lipids (ALA) via linseed was not a sufficient
means to prevent loss of ALA frommeat during a finishing period without
grass feeding. Although ALA is susceptible to biohydrogenation in
the rumen (Wachira et al., 2000) and can be degraded by up to 95%
and more, somewill escape and increasing this escape by a few percent
will greatly increase its availability for deposition. The ruminal degradation
also depends on the availability of ALA to microbes. The different
distributions of plant lipids into certain fractions are a means for
explaining the more efficient transfer of PUFA to the meat from fresh
forages compared to oilseeds (reviewed by Buccioni, Decandia,
Minieri, Molle, & Cabiddu, 2012).
