RHEOLOGICAL PROPERTIES OF CERVICO-VAGINAL MUCUS IN RELATION TO FERTILITY IN CROSSBRED COWS AND HEIFERS

This study was carried out on cows (n=20) and heifers (n=20) belonging to the Dairy farm of College of Veterinary Science and Animal Husbandry, Mhow and clinical cases of progressive farmers brought for artificial insemination to the Teaching Veterinary Clinical Complex and at the doorstep of farmers in nearby villages. The cervico-vaginal mucus samples were collected from the animals at oestrus and were immediately used for physical parameter analysis. Physical profile revealed that the mean pH value of cervico-vaginal mucus was observed in conceived and non-conceived crossbred cows and heifers, with the difference being non-significant in all the groups, but in pooled heifers, the respective values for pH were highly significant (P<0.01). The mean spinnbarkeit value of cervico-vaginal mucus was observed in conceived and non-conceived crossbred cows and heifers, with the difference being highly significant (P<0.01) in all the groups. The per cent incidence of typical, atypical and nil fern patterns of cervico-vaginal mucus samples were highly significant (P<0.01) in all the groups of conceived and non-conceived crossbred cows and heifers. Pregnancy was confirmed by rectal palpation after 2 months of insemination.
