Iron deficiency affects spatial learning in neonatal piglets
… the impact of iron deficiency on cognition using neonatal piglets as a model for human infants, as neurodevelopment in piglets resembles that of humans. Piglets were fed one of three diets with varying concentrations of iron (Fe): adequate (6.3mg Fe/kg body weight [BW]), mildly deficient (1.5mg …

Route of Nutrient Administration Alters Intestinal Immune Cell Composition in Neonatal Piglets
… composition in the developing intestine. The neonatal piglet was used as the model for the human infant. In experiment 1, piglets receiving TPN for seven days demonstrated compromised intestinal morphology and a greater number of intestinal CD4+ and CD8+ T-lymphocytes, goblet cells, and mast …

Effects of dietary intervention on inflammation and intrauterine growth restriction in neonatal piglets
… of fetal malnutrition and inflammation. Domestic piglets (Sus scrofa) were used as models to conduct the following studies, as they offer advantages in their anatomical and physiological similarity to human infants. The first study sought to determine if a pre-digested fat (PDF) system developed …

Effect of bovine lactoferrin on T cell and NK cell populations and NK cell cytotoxicity in neonatal piglets
Item marked as restricted to the 'UIUC Users [automated]' Group (id=2) by Seth Robbins (srobbins@illinois.edu) on 2013-08-30T16:47:06Z Item is restricted until 2015-08-30T16:47:05Z

Orally Administered IGF -I Combined With Partial Enteral Nutrition Alters Intestinal Morphology and Disaccharidase Activity During Parenteral Nutrition in Neonatal Piglets
Our final study investigated the mechanism(s) by which IGF-I up-regulates LPH activity. The three treatment groups were: 100% TPN, 20% PEN with or without 1.0 mg/kg IGF-I. IGF-I increased LPH activity and LPH activity per unit mature LPH ∼2-fold over PEN alone, but did not affect LPH mRNA or …

Effects of supplemental osteopontin on intestinal development and serum antibody responses to rotavirus vaccination in piglets
… mucosal immune responses in infants. Since the neonatal pig shares anatomical, physiological, immunological, and metabolic similarities with the human infants (Moughan, et al., 1992), they were selected as the animal model in our studies. Our first aim was to investigate the effects of OPN on …

Expression and Purification of the C-Terminal Domain of Porcine Epidemic Diarrhea Virus (PEDV) S1 Protein
… exposure, causing the death of 7-8 million neonatal piglets and $900 million to $1.8 billion in losses to the U.S. pork industry in 2013 and 2014. This virus causes diarrhea and vomiting which leads to dehydration and in extreme cases, death. Neonatal piglets rely heavily on passive …

Hepatic microsomal and peroxisomal docosahexaenoate biosynthesis during piglet development
… were prepared from livers of fetal and neonatal piglets by a combination of differential and gradient layer centrifugation. Microsomes, peroxisomes and combined cell fractions were incubated with [13C-U]-18:3n-3. The [M] and [M+18] isotopomers of the fatty acids in the LCPUFA n-3 pathway …

Characterization of virus strain- and pig age-dependence of porcine epidemic diarrhea virus: Implications for vaccine development
… differences between the two isolates in neonatal conventional pigs, but little is known in older pigs. Resulting data can then provide guidance on selecting appropriate PEDV strain to induce antibody responses in different ages of pigs and on selecting PEDV strains for vaccine …

Characterization of the intestinal microbiome and lactobacilli community: influence of dietary and environmental factors
… latest developed molecular biological tools, in neonatal piglets’ intestinal microbiome and lactobacilli community structure research. In Chapter 2, the latest progress of methods used in microbiota research were described and compared, the known impact of different environmental and dietary …

Colonization dynamics of oro-gastrointestinal microbes critical to infant health
… on the ileal and ascending colon microbiota of neonatal piglets was evaluated. More specifically, hundreds of lactobacilli were isolated and sequenced to characterize the lactobacilli community composition. Additionally, these lactobacilli isolates were evaluated for their ability to ferment …

Engineering solutions to address several current livestock and poultry housing challenges
… include: 1) high pre-weaning mortality of neonatal piglets in typical farrowing swine facilities, 2) maintaining egg production and sufficient well-being for laying hens under heat stress events, and 3) compromised air quality issues in most poultry housing systems. My research seeks to …

The effects of dietary protein source on the development of cholesterol metabolism
… of an earlier period in development using the neonatal piglet as a model showed that consumption of increasing proportions of whey protein decreased blood cholesterol concentrations (p $<$.05), and increased weight gain (p $<$.05). 100% casein consumption also decreased hepatic cholesterol …

The role of antibiotics metaphylaxis on developmental dynamics of fecal microbiota and persistence of antimicrobial resistome in piglets
… groups, each consisting of four, eight-week old piglets, were administered one of the antimicrobial; Tulathromycin (TUL), Ceftiofur Crystalline free acid (CCFA), Ceftiofur hydrochloride (CHC), Oxytetracycline (OTC), and Procaine Penicillin G (PPG) at label dose and route. Individual fecal swabs …

Interaction of enteroluminal neutrophils and the Escherichia coli heat-stable enterotoxin b with porcine small intestine
… in young pigs after only 2 hours;In intact neonatal piglets, three strains of enterotoxigenic Escherichia coli (ETEC) attracted greater numbers of neutrophils into the lumen and wall of the intestine than did a nonenteropathogenic strain of E. coli. Ligated loops of small intestine in …

Impact of formula additives on immune and gastrointestinal development in the piglet
… (HMO) could stimulate the development of the neonatal immune and gastrointestinal systems. Dietary βG are able to boost the natural defense mechanism by stimulating both innate (Descroix et al., 2006) and adaptive immune responses (Akramiene et al., 2007). NT are conditionally essential for …

Temperature and correlated physiologic responses as indicators of well-being
… in dramatic changes in core body temperature. Neonatal piglets have a very limited thermogenic capacity, making them highly susceptible to chilling and disease. While improvements in piglet husbandry, nutrition, and management have benefited swine in production settings, another effective means …

Early nutrition affects intestinal development and immune response in the neonatal piglet
… the effects of these early life events on neonatal intestinal, microbial, and immune development. Our first aim was to investigate the effect of route of delivery on microbial development and intestinal structure and function. Neonatal piglets were delivered either vaginally (VD) or by …
