For prophylaxis of vitamin A(VA) insufficiency and intoxication in infants, VA fortified cow's milk (VA 2000IU/L) was produced in Beijing. 629 babies were fed with the VA fortified milk (500ml or more daily) and 834 babies on commercial milk and/or breast milk from birth till 15 months of age. Serum VA concentration of the babies was estimated since the experiment seasonally over a year.
