A 2 × 2 factorial experiment was conducted to determine the effects of rearing environment (indoor (In) v. outdoor (Out)) and dietary zinc oxide (ZnO) supplementation (0 (-Zn) v. 3100 (+Zn) mg/kg feed) on the response of weaned pigs to a challenge infection with enterotoxigenic Escherichia coli (ETEC). Pigs from the two rearing environments were weaned onto trial diets at 4 weeks of age, moved ...

This study was conducted to evaluate effects of supplemental L-glutamine (Gln) and L-glutamate (Glu) on growth and physiological responses in broiler chickens. Within 8 h after hatching (36.1 ± 1.1 g BW), 480 broiler chickens were allotted randomly to 6 dietary treatments: NC (without Gln or Glu), GN5 (with 0.5% Gln), GN10 (with 1.0% Gln), GU5 (with 0.5% Glu), GU10 (with 1.0% Glu), and AG10 (wi...

An experiment was conducted to determine whether baby pigs develop hypersensitivity to dietary soybean proteins. Thirty-two pigs were orally infused with either dried skim milk (5 g/d; control) or soybean meal (48% CP; 5 g/d) from d 7 to 14 after birth. Sows were fed a corn-corn gluten meal-based diet supplemented with lysine and tryptophan to avoid exposure of pigs to soybean proteins. Pigs we...

A total of 540 one-day old male broilers Ross 308 were allocated to 6 treatments in a completely randomized designed with a 2×3 factorial arrangement (aflatoxin B1 (AFB1) and probiotics) with 6 replicates and 15 birds in each. Factors include aflatoxin B1 (control, 500 ppb) and probiotics (control, 108 cfu/mL Bacillus sp. MBIA2.40, 0.2 g Gallipro per kg). Results showed that adding 500 ppb AFB1...

The present investigation was designed to quantitatively assess the possible influence of countercurrent exchange on passive absorption from the small intestine of the dog. Villus blood flow was measured with a modification of the microsphere method. Simultaneously, the absorption from the gut lumen of five diffusible gases (H2, He, CH4, 133Xe, and CO) was determined. Villus blood flow averaged...

this study was carried out to investigate the effects of medicinal plants, prebiotic and probiotic as alternatives to antibiotics on the growth performance, intestinal morphology and ileal digestibility of nutrients in broilers. a total of 288 one- day-old broiler chicks (cobb 500) were randomly assigned to 6 treatments and 4 replicates with 12 chicks per each replicate in a completely randomiz...

The objective of this study was to establish the effects chestnut tannin extract or vitamin E added linseed oil-enriched diets on growth performance, meat quality, and intestinal morphology broiler chickens. A total 240 day-old Ross 308 male chicks were included in trial. 5% cold-pressed oil finisher (21–40 days), three feeding treatments with four replicates formed: without additives; + 200 IU...

Gut apical Na(+)-glucose cotransporter 1 (SGLT1) activity is high at the birth and during suckling, thus contributing substantially to neonatal glucose homeostasis. We hypothesize that neonates possess high SGLT1 maximal activity by expressing apical SGLT1 protein along the intestinal crypt-villus axis via unique control mechanisms. Kinetics of SGLT1 activity in apical membrane vesicles, prepar...

Glutamine, the primary metabolic fuel for the mammalian small intestinal enterocytes, is primarily assimilated by Na-amino acid cotransporters. Although Na-solute cotransport has been shown to exist in the brush border membrane (BBM) of the absorptive villus cells, the identity of Na-glutamine cotransport in rabbit small intestinal villus cells was unknown. Na-dependent glutamine uptake is pres...

s of papers 23 with ascites syndrome, reciprocal F1 crosses of the RES and SUS lines were produced. One objective of this multidisciplinary trial was to determine the effects of hypobaric hypoxia on gut development in the pure-line RES, pure-line SUS, and the reciprocal F1 crosses (RS, SR). Four hundred and eighty vaccinated, pedigreed broiler chickens (40 groups of 12 birds) were randomly assi...
