Seasonal enzyme activity changes in two aminotransferases AspAT and AlAT, acid and alkaline phosphatases and aldolase in the serum of Thoroughbred horses during a racing season.
Twenty Thoroughbred 3 year old horses (10 stallions and 10 mares), trained and raced at the Warsaw Race-Course were studied from March through November. Blood was taken approximately every 8 weeks to determine the activities of aspartate and alanine transaminases, acid and alkaline phosphatases and aldolase. It was observed that the activities of aspartate aminotransferase and alkaline phosphatase reached their maxima in July and alanine transaminase in May. The activities of acid phosphatase and aldolase showed their minima in July. Comparing these data with the literature it was noted that the changes observed are mainly seasonally-dependent; but, training had some influence on the activity of the enzymes involved in energy metabolism.
