The Piglet Intervention Center (PInC™) is a facility on the U of I Moscow campus dedicated to using neonatal piglets as a model to study impacts of nutrition interventions on the gastrointestinal (GI) tract, microbiome, immune system and neurocognitive development of neonatal mammals. There are many correlational studies examining the beneficial effects of human milk, pasteurized donor milk and infant formula on these systems. However, direct mechanistic investigations are often not possible since taking intestinal and brain samples from humans cannot be ethically justified. Similarities in the intestinal physiology, immunity and brain function between humans and pigs make the piglet a superior model among non-primate animal models to study the effects of nutrition interventions on these systems — particularly in early life.

We collaborate with the neonatal intensive care units (NICU) in Kootenai Health to study:

• Maternal stress in mothers of both term and preterm infants and its association with HM proteins/peptides
• Feasibility study on a modified eight-week mindfulness-based intervention to reduce stress, increase self-compassion and vitamin D in mothers of both term and preterm infants
• Association between reduced stress and increased self-compassion on HM proteins/peptides in mothers of both term and preterm infants
• Explore the impact of different human milk immune protein/peptide profiles on the recipient both term and preterm infant utilizing transcriptome and metabolome
• Effects of both term and preterm infant digestion on various feeding types and the subsequent impact on intestinal and immune cells
• Examine the effects of vitamin D status on depression scores using NHANES data
