Journal ArticleDOI

Butyrate: A Double-Edged Sword for Health?

TL;DR: The present knowledge on the properties of butyrate, especially its potential effects and mechanisms involved in intestinal health and obesity, are summarized.
Journal ArticleDOI

Amino acid nutrition in animals: protein synthesis and beyond.

TL;DR: Amino acids (AA) have enormous physiological importance, serving as building blocks for proteins and substrates for synthesis of low-molecular-weight substances as discussed by the authors, and therefore, functions of AA beyond protein synthesis must be considered in dietary formulations to improve efficiency of nutrient use, growth, development, reproduction, lactation and well-being in animals.
Journal ArticleDOI

Gene Expression Is Altered in Piglet Small Intestine by Weaning and Dietary Glutamine Supplementation

TL;DR: Test the hypothesis that weaning or glutamine may modulate expression of genes that are crucial for intestinal metabolism and function and reveal coordinate alterations of gene expression in response to weaning, providing molecular mechanisms for the beneficial effect of dietary glutamine supplementation to improve nutrition status in young mammals.
Journal ArticleDOI

Transient hypersensitivity to soybean meal in the early-weaned pig.

TL;DR: Reduced villus height and increased serum IgG titers to soybean proteins coinciding with inferior performance of early weaned pigs fed diets containing soybean meal indicate that conventionally processed, commercial soybean Meal may retain some antigens that can cause transient hypersensitivity in piglets.
Journal ArticleDOI

Intrauterine Growth Restriction Affects the Proteomes of the Small Intestine, Liver, and Skeletal Muscle in Newborn Pigs

TL;DR: The novel findings suggest that cellular signaling defects, redox imbalance, reduced protein synthesis, and enhanced proteolysis may be the major mechanisms responsible for abnormal absorption and metabolism of nutrients, as well as reduced growth and impaired development of the small intestine, liver, and muscle in IUGR neonates.
