Zinc, Copper, Iron. Calcium Phosphorous and Magnesium contents were determined in early milk samples in 72 mothers from Caracas city. The samples were collected during three different lactation stages: calostro (3 days), transitional (7 days) and mature milk (21 days). The more significant changes in the concentration of the studied elements were observed during the first two weeks, them they stabilize during the third week. The Zn, Cu, Fe, Ca, P and Mg average concentration found in calostro samples were 7.1 +/- 2.5 micrograms/ml; 0.52 +/- 0.15 microgram/ml; 0.49 +/- 0.14 microgram/ml; 214 +/- 62 micrograms/ml, 107 +/- 27 micrograms/ml and 33.3 +/- 7.5 micrograms/ml. respectively. For the transitional milk samples the average concentration found for the studied elements were: 4.0 +/- 1.0 micrograms/ml; 0.50 +/- 0.10 microgram/ml; 0.38 +/- 0.08 microgram/ml, 292 +/- 62 micrograms/ml; 213 +/- 36 micrograms/ml and 30.4 +/- 5.2 micrograms/ml. For the mature milk samples the results were: 2.8 +/- 2.7 micrograms/ml; 0.47 +/- 0.08 microgram/ml; 0.36 +/- 0.09 microgram/ml; 244 +/- 49 micrograms/ml; 175 +/-35 micrograms/ml and 25.2 +/- 3.3 micrograms/ml. The concentration range for all trace elements studied (Cu, Fe and Zn) can be considered normal. For the major elements (Ca, P and Mg) the results obtained in our work are similar to those reported for other countries. These facts allows to conclude that the nutritional state of this mother population is adequate to satisfy the lactate's requirements during their first live stage.
