The study of the caloric value of breast milk is ofgreat importance in the early stages ofgrowth of the child. The crematocrito usage permits, to determine the energy contribution of breast milk. Research question: What will be the calorie content of breast milk from a precise volume of milk, measured by the technique of crematocrito in samples of fresh and frozen milk in population of high altitude, La Paz, Bolivia, term 2015. General Objective: To determine the calorie content of breast milk from a precise volume, measured by the technique of crematocrito in samples of fresh and frozen milk in population of high altitude, La Paz, Bolivia, term 2015. Methodology: It was a descriptive cross-sectional study, 43 samples of fresh milk and 43 milk samples after freezing at - the 8th -20 ° C, from milk samples from mothers in children under 2 years of periurban areas of the city of La Paz, at 3700 meters altitude. Results: The average difference of crematocrito value measured in samples of fresh and frozen breast milk is 1.4 ± 1.2%, and the difference in calorie content is 90.2 kcal. Conclusions: It has been shown that there is a decrease in fat and caloric intake in samples of frozen breast milk samples compared to fresh milk, this reduction was greater in samples with greater amount of freezing time
