1. The diurnal changes in the glucose level and in activity of FDPA, A1AT and AspAT in four pregnant standard-bred mares were studied. 2. As a control four barren mares, were kept and examined in the same conditions. 3. Blood samples were taken every 4 hr for one day, each month, throughout pregnancy, or one year. 4. A diurnal rhythm in activity of A1AT and AspAT in barren mares was found. The pregnancy masked diurnal rhythm in activities of both transaminases. 5. No diurnal rhythm in glucose level and FDPA activity in both groups of mares was observed. 6. Seasonal cyclicity was found in all indices studied, in both groups of mares. 7. The pregnancy did not abolish cyclicity in parameters studied but modified their behaviour--causing a shift of acrophases (glucose, FDPA, AspAT) and lowering the amplitudes (FDPA, A1AT, AspAT).
