This study aimeds to find out the sexual behavior of Ongole Crossbred (PO) bull and
cows kept in intermittent colony housing system on smallholder farmers. One head of a bull
and four head of cows were kept in intermittent colony housing system. Sexual behavior of
bull observed were oro-nasal contact, flehmen, mounts response, and services. Sexual
behavior of cows observed were mounting, standing to be installed, and mucus secretion. The
sexual behavior observation of bull was carried out in all phases of the estrus cycle and cows
were observed only in the estrus phase. Estrus was determined by observation of the vaginal
epithelial cells. The data were analyzed descriptively. The results showed that there was a
significant increase in all parameters of bull sexual behavior during the estrus period (P<0.05).
The cows showed sexual behavior and characteristics of right conditions on vulva during
estrus. All cows (100%) had mounting behavior and remove mucus in their vulva. Increased
intensity of bull sexual behavior during the period of the estrus was followed by the
appearance of signs of estrus in the cows. PO bull kept in a intermittent colony with the cows
showed higher sexual behavior during the cows in the estrus phase and followed by the
appearance of behavior and estrus characteristics in the cows. |
