Abstract:
Present study was conducted among 40 selected cows with an aim to investigate the corporeal characteristics of cervico-vaginal mucus (CVM) in relation to fertility in cows. The CVM samples were collected aseptically on the day of estrus prior to the artificial insemination. Physical characteristics of CVM were studied immediately after collection of cervical mucus. Study reported that per cent of fertile and infertile estrus cows were 57.5 and 42.5, respectively. The physical characteristics of CVM viz., clear colour, thin consistency, typical fern pattern and good spinnbarkeit value (≥12.00 cm) favored the higher conception rate in cows. The alkaline pH (≥8.30) of CVM has favorable effect on the conception rate as compared to less alkaline pH (≤7.76). The study concluded that the corporeal characteristics in CVM are helpful to detect the fertility in cows.
