Abstract

This research aims to determine the biological response of administering the PGF2&#945- hormone to the estrous activity of Madurese cows. This research method uses two observation techniques, namely estrus synchronization by administering the PGF2&#945- hormone Alfaglandin and observing natural estrus.. The data were analyzed by using the t test using the Software for Research statistix 10. The results showed that the frequency of estrus at the same time of observation was not significantly different from the two treatments (p>0.05), the highest frequency of estrus occurred at 18.00-20.00 in synchronized cows or not. The results of visualization of estrus showed cervical mucus, swollen vulva, and vaginal pH had the same percentage, while the vaginal temperature and duration of estrus had different percentages. The conclusion of this study is the frequency of estrous events, estrus visualization (cervical mucus discharge, swollen vulva, vaginal pH, and length of estrus), and the appearance of cervical ferning has the same response, while estrus temperature has a variable response.
