| Sumario: | Milk samples from healthy lactating women, who had been supplemented with bovine milk serum proteinand receiving an adequate food regimens, were evaluated on protein composition and IgA concentration,and compared with those data from control group. The effect of protein supplementation on protein andIgA concentrations was investigated in milk samples from 90 nursing mother, who were supplemented with14g of protein during the last trimester of pregnancy and with 20g at the first three months of lactation. Theprotein contents in mother milk were determined at 30 (T30), 60 (T60) and 90 (T90) days of post-lactation.IgA concentration was analyzed at 30 (T30) and 60 (T60) days of lactation. The average protein contentsin milk samples from supplemented were 1,22 g/dL at T30; 1,16 g/dL at T60 and 1,07 g/dL at T90, andbeing 0,94 g/dL at T30; 0,79 g/dL at T60 and 0,79 g/dL at T90 in milk samples from control group. IgAconcentrations in milk from supplemented mothers were 109,1 mg/dL at T30; 94,4 mg/dL at T60, and incontrol group were 72,8 mg/dL at T30 and 65,0 mg/dL at T60. The overall results demonstrated a positiveeffect of proteins supplementation on human milk composition, when compared with the control group. |
