In our previous trial, diets supplemented with 0, 0.5, 1.0, or 1.5 mg pEGF /kg diet have found that piglets supplemented with 1.0 to 1.5 mg pEGF /kg diet could stimulate jejunal alkaline phosphatase (ALP) and maltase mRNA expression and lactase activities (Lee et al., 2007).
This study attempted to understand whether dietary pEGF and Gln supplementation enhances the growth and function of the gastrointestinal tract in early-weaned piglets.
Piglets were weaned at 14 [+ or -] 1 day of age, and fed a corn-soybean meal-whey basal diet supplemented with either inclusion of 1.0 mg pEGF supernatant /kg diet or 0.5% Gln (Ajinomoto, Tokyo, Japan) both alone and in combination.
Diets supplemented with pEGF and Gln failed to influence the ADG, ADFI, and feed efficiency during the 14 or 28 days of testing.
This factorial design work attempted to investigate the effects of pEGF and Gln on the growth performance, intestine development and immune response of early weaning piglets particular in the interactive effect of pEGF and Gln.
