IGF1 and Hypoglycemia: Preterm pigs delivered at 90% gestation show morbidities similar to those in many preterm infants, including reduced growth (41), impaired postnatal gut, brain and immune development (32–34, 41, 43, 44, 60, 64), neonatal hypoglycemia (41, 63) and reduced IGF-1 levels (41, 42), relative to their term-born counterparts.
