Author(s): Nilotpal Das, Manjyoti Bhuyan and Anil Deka

Abstract: Anovulation is a common endocrine dysfunction that results in development of an ovular heat in which animal exhibits normal oestrus behaviour at normal oestrus cycle length interval and the ovarian follicle reaches preovulatory size but it fails to ovulate. A Holstein Friesian crossbred cow about five and half years old was attended at the doorstep of a private dairy farmer near College of Veterinary Science, Khanapara, AAU, Ghy-22 with a history that the cow has been repeated since last 4 months after consecutives artificial insemination. On re-examination it was found that the both ovaries were smooth. Following thorough examination on next heat, the cow was administered 2.5 ml synthetic analogue of GnRH (Gynarich, Intas Pharmaceuticals Ltd.) intramuscularly at the time of artificial insemination. An area specific mineral mixture (AAUVETMIN, developed by Assam Agricultural University) @ 40 g per day orally was also provided for 20 days as supportive. In present investigation, 50% conception rate in crossbred cow by using 2.5 ml of injection of synthetic analogue of GnRH by i/m administration at the time of insemination.
