abstract
The present study was conducted to find out the status of genital changes in twenty confirmed silent oestrus and twenty normal oestrous crossbred cows. It was cleared that vulvar swelling, pink vulvar mucous membrane, scanty vaginal discharge, relaxed cervix, presence of uterine tone and presence of mature follicle on the day of detected estrus and presence of corpus luteum on day 10 of estrous cycle were the common clinically detectable genital changes associated with silent estrus cows like that of normal oestus cows. From these clinical findings it was confirmed that the animals were cyclic though all animals did not exhibit behavioural signs of estrus. Therefore, clinico-gynaecological examination of postpartum anoestrus cows at regular interval might be a diagnostic tool for detection of cyclicity in silent estrus crossbred cows in field condition.
