Enzymes activities were also determined in uterine and cervical rinsings. Glycogen levels decreased after day 8 in the endometrium, caruncles, cervix and vagina. Independent glycogen (starch) synthasem showed decreased activity in the cervical mucosa following mating and peaks of activity at days 0 and 15 in the oviduct. Following mating both independent and total glycogen (Starch) synthase activities increased in caruncular tissue. Alfa-Amplase activity declined from day 0 to day 44 in the oviducal mucosa, but showed a slight peak at day 15 in the endometrium. The levels of total and active glycogen phosphorylase did not change significantly in any tissue but did show a peak of activity in the uterine and cervical rinsings at days 8 and 15 respectively. The results are interpreted as showing increased turnover of glycogen in the oviducal and cervical mucosa at mating, in the intercaruncular endometrium in the period before implantation, and in the caruncles from the start of implantation.  aCervix  aCopulation  aEnzymology  aEwes  aFemales  aGlycogen  aGlycogen synthase kinases  aMetabolism  aPhosphorylase  aPregnancy  aReproduction  aSheep  aUterus  aAtividade Enzimática  aOvelha  aOvino  aPrenhez  aReprodução  aReprodução animal  aÚtero  aAlpha-Amylases  aGlicogênio  aHistofisiologia1 aMURDOCH, B.
