None of the trials individually found any statistically significant difference in the incidence of NEC .
However , meta- analysis found that feeding with donor human milk was associated with a significantly reduced relative risk ( RR ) of NEC .
OBJECTIVES To determine if enteral feeding with donor human milk compared with formula milk reduces the incidence of necrotising enterocolitis ( NEC ) in preterm or low birthweight infants .
Adequacy of expressed breast milk for early gwoth of preterm infants.
Poor weight gain observed in preterm infants who were fed expressed breast milk compared with those fed a cows ' milk formular  prompted a detailed study of early postnatal growth in preterm infants fed these two milks . 68 infants were divided into two categories by gestational age at birth ( i ) 28 - 32 weeks ( n=28 ) , ( ii ) 33 - 36 weeks ( n=40 ) . They were r and omly allocated to a feed of expressed breast milk or a milk formula ( Ostermilk 1 ) . Rates of weight gain , linear growth , and head circumference growth were evaluated over two periods : birth-1 month , 1 - 2 months . The younger group who were fed breast milk showed slower overall growth rates over the first month than those fed formula . In the second month , and for the older infants over both of the 2-monthly periods , growth rates were similar in the two feeding regimens . It is concluded that expressed breast milk is inadequate for the growth of very immature preterm infants during early postnatal life
