Weaning is a stressful event for piglets characterized by changes in diet, social dynamics, and environment. The abrupt switch in diet form and composition is a challenge for newly weaned pigs that do not yet have a fully mature gastrointestinal tract and contributes to post-weaning growth check. The sulfur amino acids methionine and cysteine have key roles in animal health and production. In addition to their use for muscle growth, methionine is used to produce cysteine and cysteine is needed for glutathione synthesis, a major antioxidant that may play a key role in gut health. However, our understanding of these nonproduction roles of sulfur amino acids in weaned pigs and its effect on methionine and cysteine requirements is lacking.
The long-term goal of this research is to enhance the capacity of piglets to adapt to weaning-induced nutritional stress by targeting sulfur amino acid nutrition. I am also interested in exploring aspects of sulfur amino acid nutrition and metabolism in a preterm piglet model of prematurity and the molecular mechanisms that contribute to muscle growth potential in livestock animals.
