Oestrus behaviour in Swamp buffalo cows under organized farm

A study was conducted on 17 Swamp buffalo cows maintained at Network Project on Buffalo improvement (Swamp), College of Veterinary Science, Assam Agricultural University, Khanapara, Guwahati, Assam to accumulate data on oestrus behaviour. Oestrus behaviour was studied based on direct observations. The study revealed that behavioural signs of oestrus were not prominent in Swamp buffalo cows. Oedematous vulva and hyperemia of vaginal mucus membrane were the two clinically detectable external signs exhibited by all animals during oestrus. Relaxation of cervix, moderate uterine tone and presence of palpable ovarian follicle were the common genital changes detectable on rectal palpation of the genital organs in all animals during oestrus.
