ABSTRACT

The task of this research was to correlate blood selenium, iron and zinc content of horses to the recuperation time after physical excercise measured by cardiac frequency. Mean blood Se (73 ng/ml), Fe (52.3 µg/ml), Zn (3.5 µg/ml) and hair Se (440 ng/g), Fe (3.8 µg/g) and Zn (9.3 µg/g) contents were measured by atomic absorption spectrophotometry in 10 to 11 year old crossbreed horses. Mean cardiac basal frequency was 37/minute. Besides, the overall mean cardiac frequency after one hour of physical excersise was recovered to basal frequency in 37 minutes. Mean selenium content (115 ng/ml) and iron (62 µg/ml were found in those horses with the fastest recuperation rate 20 minutes afterwards. Nevertheless, those horses with 60 ng Se/ml and 49 µg Fe/ml recovered 40 minutes afterwards. Blood selenium content was different among horses (it varied from 115 to 60 ng/ml) receiving the same feed. Blood Zn content did not correlate with the recuperation time.
