ΣΥΜΒΟΛΗ ΣΤΗ ΜΕΛΕΤΗ ΤΗΣ ΜΕΤΟΙΣΤΡΙΑΣ ΑΙΜΟΡΡΑΓΙΑΣ ΤΩΝ ΑΓΕΛΑΔΩΝ ΚΑΙ ΜΟΣΧΙΔΩΝ

THE METESTRUAL BLEEDING IN A CATTLE POPULATION (1760 COWS AND HEIFERS) IN THE DISTRICT OF THESSALONIKI-NORTH GREECE WAS STUDIED. IT WAS FOUND THAT BETWEEN THE EXAMINED COWS THE PERCENTAGE OF THOSE WITH M.B. WAS 10,18% AND BETWEEN THE HEIFERS WAS 21,31% (P<0,001). THE COMMONEST TIME THAT THE M.B. APPEARED (65% OF THE EXAMINED ANIMALS) WAS 48 HOURS AFTER THE ONSET OF OESTRUS. THE SILENT OESTRUS APPEARED TO A PERCENTAGE OF 12,27 IN THE ANIMALS WITH M.B. WHILE AMONG THE ONES WHICH SHOWED NO BLEEDING (CONTROLS) SILENT OESTRUS APPEARED TO A PERCENTAGE OF 1,63% (P<0,001). THE CONCENTRATION OF CA, P, PROGESTERONE AND OESTROGENS IN BLOOD WAS STUDIED. 1) IT WAS FOUND NOT SIGNIFICANT DIFFERENCE IN CA BLOOD CONCENTRATING BETWEEN ANIMAL WITH OR WITHOUT M.B. 2) IT WAS FOUND SIGNIFICANT INCREASE IN P BLOOD CONCENTRATION IN ANIMALS WITH M.B. 48 HOURS AFTER THE ONSET OF OESTRUS. 3) IT WAS FOUND SIGNIFICANT DECREASE IN PROGESTERONE BLOOD CONCENTRATION IN ANIMALS WITH M.B. 48 HOURS AFTER THE ONSET OF OESTRUS.
