Postpartum follicular project and sexual behavior were evaluated in tropical environments among swamp buffaloes (Bubalus bubalis). Sixteen multiparous swamp buffaloes, aged 4-12 age (weighing between 432-676 kg), were noticed starting from 5-29 days after create. Ovarian follicular activity was regularly monitored using a evident-time B-mode uninterrupted array ultrasound scanner (Aloka SSD-500, Tokyo, Japan) outfitted with a 7.5 MHz transrectal transducer. Estrous discovery involved personal attention, video recording, and amount of vaginal discharge. Uterine involution averaged 28.74+1.21 days (mean + SEM, range 22-41 d, n=16). Before the first ovulation, follicular activity attended a wave-like pattern. There were no meaningful differences in follicular growth rates and maximum blood vessel diameter in the second, third, and one of four equal parts postpartum cycles, whereas the first ovulation's follicular tumor was notably lower (p<0.05). Short ovarian phases were observed in 93.3% of buffaloes between the first and second ovulation (10.14+40 d) and in 50.0% betwixt the second and third ovulation (12.00+1.53 d). However, individual buffalo experienced a more interminable estrus cycle unending 27 days. Behavioral indicators of estrus following the first postpartum ovulation were less obvious compared to subsequent ovulations. For optimum reproductive efficiency, swamp buffaloes bear ideally come from between 1 to 2 months postpartum during the second ovulation.
