  • a Data shown are the number of animals that were identified (+NEC) and (−NEC) in each group, followed by group totals and the percent (+NEC) incidence. Formula-fed neonatal rats were cold/asphyxia stressed twice daily and were assigned into groups as indicated by line. NEC was evaluated based on previously published histological criteria. Groups were statistically significantly different at p < 0.001 (χ2 test).
