Based on an analysis
of published data, the growth-promoting effect of CA is partly due
to the gastrointestinal acidification and antimicrobial effects in pig
(Partanen andMroz, 1999). It is generally considered that lower gastric
pH induced by CA result in increased activity of digestive enzymes,
which lead to higher nutrients availability (Castillo et al., 2014;
Márquez et al., 2012).
