The goal of this clinical trial is to evaluate whether multi-strain probiotics of lactobacillus and bifidobacterium can prevent necrotizing enterocolitis (NEC) in preterm infants born at less than 32 weeks of gestation. The main questions it aims to answer are:
* Does the use of a multi-strain probiotic combination reduce the incidence of NEC in preterm infants? * Are there any adverse effects associated with the administration of this probiotic combination?
Infants born between <32 0/7 weeks gestation.
