reduced with the increasing level of Pal inclusion. Actually, broilers
among the 3 treatments exhibited similar feed intake during the
42 days. Thus, the similar growth performance was not likely to have resulted
from enhanced feed intake, which can compensate nutrients dilution
induced by exogenous Pal supplementation. The simultaneously
enhanced digestive function and the ability of Pal to adsorb adverse factors
in the feed and to improve intestinal morphology and barrier function
(Schell et al., 1993; Zhang et al., 2013)would together contribute to
the similar growth performance.
