Abstract

The effects of feeding different types of fiber to weanling pigs on growth performance, intestinal and liver cytokine expression, circulating acute-phase proteins, and IGF-I were evaluated. Intestinal tissue abundance of DNA, protein, and phosphorylated S6 kinase were also determined. Pigs (n = 120; initially 5.2 kg and 24 d of age) were randomly assigned to diets containing 1 of 4 fiber sources: 1) control diets containing no added fiber source, 2) diets containing 7.5% distillers dried grains with solubles (DDGS), 3) diets containing 7.5% soybean hulls, or 4) diets containing 7.5% citrus pulp. The experimental diets were fed for 4 wk in 2 phases (phase 1, wk 1 and 2; phase 2, wk 3 and 4). Intestinal tissue samples, liver samples, and blood samples were collected from a subset (n = 24; 6 pigs/treatment) of the pigs on d 7, and blood samples were collected from another subset (n = 24; 6 pigs/ treatment) of pigs on d 28 of the experiment. Dietary treatment had no effect on ADG, ADFI, or G:F throughout the experiment. Likewise, pig BW variability (CV), plasma IGF-I, or the plasma concentration of the acute-phase proteins, alpha(1)-acid glycoprotein, C-reactive protein, and haptoglobin, were not affected by dietary treatment.
