This study was conducted to determine the sexual behaviors of Ongole crossbreed
bulls and cows with colony housing systems. Bull sexual behaviors was observed, including
Oro-Nasal Contact (ONC), Flehmen, Mounts Orientation Response (MOR), Mounts, and
Services. Cows sexual behaviors were: Mounting, Standing-to-be-mounted (STBM), and
vulvar appearance (color, swelling, secretion of mucus). Sexual behaviors were observed in
24 hours, with the estrous cycle stage was determined by changes in the character of the
vaginal epithelial cells. The data was analyzed by using statistic varian one-way method. The
result showed that Ongole crossbreed bulls had sexual behaviors (ONC, Flehmen, MOR,
Mounts, and Services) significantly higher than cows with estrous phase (P<0.01). The
intensity of bull sexual behaviors had been influenced by the phase of estrous of the cows. At
the time of estrus, the cows had the response of mounting (25%), STBM (100%), reddening
vulva (75%), swelling vulva (75%), and mucus secretion (100%) that could be a factor of
high sexual behavior intensity of the bulls. The conclusion of this study was bulls and cows
that kept with the colony housing system had increased sexual behaviors when the cows at the
estrous phase.
