ABSTRACT

Iron (Fe) and zinc (Zn) are two elements considered essential for animal health. The objective of this study was to obtain information about this two oligoelements in blood in three categories of female bavines. Animals were sampled at three different times of the year, and content of Fe and Zn in blood was dosed by atomic absorption spectrophotometry. Fe concentration varied on different dates for the three animal categories. In autumn, Fe concentration in heifers was different from that found in calves and cows. No differences were detected between categories on the other two times of the year. Zn content changed through time and category. Concentration diminished through time in calves and cows, and it was increased in heifers. The highest difference was found towards the end of the spring. Results obtained were within the normal range. Differences among categories may have been due more the to variation in the diet than to the physiological state or the age of the animal.
