| Popis: | To study the effects of hormone treatment on the cervical mucus of cows mucus was collected daily from ovariectomized and normal heifers treated with oral progestagens. After determination of protein and chloride content the ratios of chloride to total protedin (CMIt) and chloride to residual protein (CMIr) were calculated. The CMIr and CMIt levels were influenced by breed and dose of stilbestrol. CMIr was a more sensitive criterion of estrogenic action than CMIt. The CMIt peaks coincided with estrus and the CMIt peaks occurred about 8 hours earlier. In nonovariectomized animals the CMI was related to the occurrence of estrus and could be used to monitor ovarian function in synchronization studies.(Authors modified) |
