Feeding fermentable carbohydrates (FC) to weanling pigs may reduce the negative impact of
\nproteolytic fermentation on gastrointestinal health and function. A total of 144 newly weaned pigs [6.23 kg body weight
\n(BW); six pens per treatment; six pigs per pen) were used to determine the interactive effects of feeding additional
\nfermentable protein (FP) and FC on growth performance, gastrointestinal function and intestinal health. Dietary
\ntreatments, based on a 2×2 factorial arrangement, were: (1) basal diet (control); (2) control +10% poultry meal (PM) as
\nFP source; (3) control +5% beet pulp (BP) as FC source; and (4) control +10% PM and 5% BP. Diets were formulated to
\nbe similar in digestible energy (DE) and digestible amino acid contents. In general, no interactive effects of FC and FP were
\nobserved (P>0.10). During the 3-wk post-weaning period, feeding FP reduced average daily gain (ADG) (242 vs. 269 g
\nd-1; PB0.05), while FC increased ADG (269 vs. 243 g d-1; PB0.05). Overall, feed intake did not differ between
\ntreatments (P>0.10). On days 14 and 28 post-weaning, Clostridia spp. counts in colon contents, counts of white cells and
\nsegmented neutrophils in blood were lowered (P<0.05) by feeding FC. Blood urea nitrogen was increased by feeding FP\n(9.5 vs. 6.5 mg dL-1; P<0.05), while ammonia concentration in colon contents was lowered by FC (154 vs. 193 mg mL-1)\n(P=0.06). Among biogenic amines, levels of tyramine (140 vs. 304 nmol g-1 DM) and spermidine (174 vs. 219 nmol g-1\nDM) in colon contents were lowered (P<0.05) by FC. Acetic, proprionic and butyric acid contents in colon contents were\nincreased by feeding FC, while valeric and caproic acid content decreased by feeding FP (P<0.05). Feeding FC and FP\nhad no effect (P>0.10) on colon histology, pH, fecal consistency score and organ weights. Results suggest that FP and FC
\nhave independent effects on newly weaned pigs, while effects appear partly related to changes in gut microbiota.<\/p>\n","protected":false},"excerpt":{"rendered":"
