Supplemental methionine (Met) is widely used within the swine industry; however, data are limited regarding the effect of Met sources on carcass cutability and meat quality. The objective was to determine the effects of L-Met (LM, 99%), DL-Met (DLM, 99%), or calcium salt of DL-Met hydroxyl analogue (MHA, 84%) in finishing pig diets on carcass chara...
The intestinal barrier of pigs can be compromised by many factors including health challenges, off-feed events, and environmental stressors. If dysregulated barrier function is caught early, proper treatment can be initiated to potentially prevent more severe complications to overall health. However, there are few procedures to measure intestinal f...
In this study, we investigated the influence of feeding style on growth performance, circulating insulin concentrations, and spatial preference within the home-cages (HC) of young pigs. Pigs (n = 43 boars) were weaned on postnatal day (PND) 2, allotted to treatment based on litter of origin and body weight (BW), and reared artificially over a 15-d...
Frequent incidence of postweaning enterotoxigenic Escherichia coli (ETEC) diarrhea in the swine industry contributes to high mortality rates and associated economic losses.

Broilers are commonly exposed to coccidiosis infections, and the use of dietary strategies to reduce losses in growth performance has practical implications for the poultry industry. Methionine (Met) is typically the first limiting amino acid for broilers and is involved in metabolic and immunological pathways; however, literature is conflicting on...
Microbial protease co-ingestion with pea protein increased postprandial plasma total amino acid concentrations across 5 hours compared to placebo in health adults, as well as increasing branched chain, essential, and total amino acid availability in the early postprandial period (0‒2 hours). Future studies are warranted to investigate the metabolic...

Sialylated oligosaccharides, including 3ˊ-sialyllactose (3ˊ-SL) and 6ˊ-sialyllactose (6ˊ-SL), comprise a large portion of human milk and have been known to support development over the first year of life. While research has investigated the impact of early-life supplementation, longer-term supplementation remains relatively unexplored. Consequently...
Ruminants’ milk is commonly used for supplying nutrients to infants when breast milk is unavailable or limited. Previous studies have highlighted the differences between ruminants’ milk composition, digestion, absorption, and fermentation. However, whether consuming different ruminants’ milk impact the appearance of the circulatory blood metabolite...
Dextran sodium sulfate (DSS) is commonly used to induce intestinal (i.e., colonic) inflammation in a variety of animal models. However, DSS is known to cause interference when using quantitative-real time polymerase chain reaction (qRT-PCR) methods, thereby invalidating accurate and precise measurement of tissue gene expression. Therefore, the goal...
Background: Digestive enzymes are commonly consumed with food to improve macronutrient digestion and support gastrointestinal comfort. Dietary supplementation with microbial proteases, in particular, is an underutilized approach to enhance dietary protein digestion and postprandial blood amino acid (AA) concentrations.

Hydrocephalus is a neurological disease with an incidence of 0.3-0.7 per 1000 live births in the United States. Ventriculomegaly, periventricular white matter alterations, inflammation, and gliosis are among the neuropathologies associated with this disease. We hypothesized that hippocampus structure and subgranular zone neurogenesis a...
The gastrointestinal (GI) microbiota has co-evolved with the host in an intricate relationship for mutual benefit, however, inappropriate development of this relationship can have detrimental effects.

However, the mechanisms by which either act remain largely unknown. We...
Background.
Many animal models have been used to study the pathophysiology of hydrocephalus; most of these have been rodent models whose lissencephalic cerebral cortex may not respond to ventriculomegaly in ways similar to gyrencephalic species and whose size is not amenable to evaluation of clinically-relevant neurosurgical treatments. Fewer model...
Intro: Pigs have been an increasingly popular preclinical model in nutritional neuroscience, as their anatomy, physiology, and nutrition requirements are highly comparable to those of humans. Eyeblink conditioning is one of the most well-validated behavioral paradigms in neuroscience to study underlying mechanisms of learning and memory formation i...
Introduction
Over the last 40 years, the domestic pig has emerged as a prominent preclinical model as this species shares similarities with humans with regard to immunity, gastrointestinal physiology, and neurodevelopment. Artificial rearing of pigs provides a number of advantages over conventional rearing (i.e., true maternal care), including care...
Background
Neurodevelopmental studies utilize the pig as a translational animal model due to anatomical and morphological similarities between the pig and human brain.

Background: Human milk contains both arachidonic acid (ARA) and docosahexaenoic acid (DHA). Supplementation of infant formula with ARA and DHA results in fatty acid (FA) profiles, neurodevelopmental outcomes, and immune responses in formula-fed infants that are more like those observed in breastfed infants. Consequently, ARA and DHA have been histo...

Beginning on postnatal day (PND) 2, male pigs received one of th...
Apart from its role as a digestive and absorptive organ, the gastrointestinal (GI) tract is a vital immune organ that encompasses roughly 70 % of the total immune cells of the body. As such, the physical, chemical and nutrient composition of the diet influences overall GI function, effectively as an immune organ. With the improvement in feed techno...

Background
Sialyllactose (SL) is a highly abundant oligosaccharide in human milk that has been shown to influence intestinal maturation and cognitive development and exert bifidogenic effects on the gut microbiota. The SL content of infant formula is significantly less than that of human milk, therefore there is interest in determining the effect o...
Sialyllactose is a milk oligosaccharide composed of a sialic acid conjugated to a lactose molecule that is present in human, bovine and porcine milks.
