AB - This study was conducted to investigate the effect of Achyranthes
Bidentata Polysaccharide (ABP) on growth performance, inflammatory responses
and hormones in weaned piglets after Escherichia coli Lipopolysaccharide
(LPS) challenges. A total of 48 crossbred (Duroc x Large; White x Landrace)
male pigs weaned at 28 days of age (8.45±0.14 kg) were randomly allotted
to one of four treatments by initial BW in a 2x2 factorial design that included
a dietary addition of ABP (0 or 500 mg kg-1) and immunological challenge
(with LPS or saline). On day 14 and 21, pigs were injected intraperitoneally
with either 100 μg kg-1 BW of LPS or an equivalent amount of
sterile saline. Blood samples were obtained 3 h after injection for analysis
of Tumor Necrosis Factor-α (TNF-α), Prostaglandin E2 (PGE2),
cortisol, Growth Hormone (GH) and Insulin-like Growth Factor (IGF)-I. The results
showed that LPS challenge decreased Average Daily Feed Intake (ADFI) (p<0.05)
from 14∼21 and day 21∼28. ABP increased ADG (p<0.05) and ADFI (p<0.05)
from day 21∼28. An interaction (p<0.05) between LPS challenge and diet
was observed for the plasma concentration of TNF-α, PGE2, cortisol, and
IGF-I after both LPS challenges such that among LPS-treated pigs, pigs fed the
ABP diet were lower for TNF-α (p<0.05) and higher IGF-I (p<0.05)
than those receiving the control diet. These results indicated that ABP alters
the release of inflammatory cytokines that may lead to improved pig performance
during an immunological stress.
