Fern Pattern of Cervico-Vaginal Mucus in Relation to Fertility in Crossbred Cows and Heifers

This study was carried out on crossbred cows (n=20) and heifers (n=20) belonging to Dairy farm of the College of Veterinary Sciences and A.H. Mhow and clinical cases of progressive farmers brought for AI to the Teaching Veterinary Clinical Complex and at the doorstep of farmers in nearby villages. The cervico-vaginal mucus (CVM) samples were collected from the animals at oestrus before AI and were immediately evaluated for physical properties particularly fern pattern. Pregnancy was confirmed by rectal palpation after 2 months of insemination. Physical profile revealed that the variations in per cent incidence of typical, atypical and nil fern patterns of CVM samples were highly significant (P less than 0.01) in both the groups of conceived and non-conceived cows and he
