Abstract

Milk studies within two days post delivery in 90 randomly selected women of three socio-economic (low, middle and high) and three age groups (< 25, 26-32 and > 33 years) of Faisalabad, Pakistan, revealed an overall concentration of vitamin-A to be 718.85 RE/L. The milk vitamin-A showed non-significant difference between socio-economic groups, but was higher (P<0.01) in women of > 33 years (863.41 RE/L) of age. The mean specific gravity of milk was 1.0265±264 and the pH was 7.0876 and showed non-significant difference in socio-economic and age groups. The mean total milk proteins was 1.31±4 per cent and was higher (P<0.05) in women of 26-32 years of age, however, it showed non-significant difference between socio-economic groups. The mean milk lactose and fat was 5.76±5 and 2.89±3 per cent, respectively and showed non-significant difference between socio-economic and age groups.
