Rapid colorimetric determination of oestrogenic hormones in pregnant mares


Rapid colorimetric determination of oestrogenic hormones in pregnant mares



Research Bulletin of Obihiro University, Series I 9(2): 249-256



In 11 pregnant mares, oestrogen secretion in the urine was measured by the colorimetric method described by A. Kambegawa (Zeitschrift fur kombinierte Forschungsergebnisse, 16 : 935-945) at various intervals between the 80th and 300th day after mating. Oestrogen concentration was highest between the 140th and the 180th day of pregnancy, and decreased markedly after 240 days.
