The content of heavy metals in the mammary gland secretions of mares should be tested not only because of the possibility of human consumption of mare's milk, but also because these elements influence the development of foals in the suckling period and later in adolescence. The aim of the research was to assess the dependence of the concentration of heavy metals in mammary gland secretions on the age of the mare. The study was carried out on 16 Thoroughbred mares. Mares aged 4 to 19 years were divided into 2 research groups: Group Y - young mares = 10 years of age (n = 8) and Group O - mares older than 10 years of age (n = 8) The experimental material consisted of colostrum collected up to 12 hours after delivery and milk collected on the 3rd day after foaling. The concentrations of metals (Zn, Cu, Ni, Mn, Fe, Pb, and Cd) were determined by atomic absorption spectrometry (Unicam 929 AAS spectrometer). All elements (Ni, Zn, Cu, Mn, Fe, and Cd) analysed in the colostrum showed higher concentrations in young mares. Highly significant differences were noted for Ni and Cd and significant differences for Fe. The statistical analysis showed highly significant differences for milk Cu content between older and young mares; highly significant differences for Cu and Cd and significant differences for Zn between the milk and colostrum of older mares; and highly significant differences for Cu and significant differences for Cd between the milk and colostrum of younger mares. Lead (Pb) was not detected in the samples. [ABSTRACT FROM AUTHOR] |
