dc.description.abstractAnestrum is one of the major causes of infertility in bovines. A four year old Holstein Friesian crossbred heifer was presented to the Teaching Veterinary Clinical Complex, Veterinary College and Research Institute, Tirunelveli with a history of not showing estrus signs for the past seven months. Rectal examination revealed normal uterus with inactive ovaries was palpable. Transrectal ultrasonography of the right ovary revealed a follicle measured about 8.5 mm in diameter, on the contra lateral ovary no follicle could be detected and corpus luteum could not be detected on both ovaries.Nine days later animal was re-examined and found to have a follicle on the right ovary measured 8.6 mm in diameter. Hence the condition was diagnosed as Anestrus and treated with Controlled Internal Drug Releasing Device (Progesterone device), which was inserted in the vagina and administered estradiol benzoate 2 mg total dose intramuscularly. Eight days later CIDR was removed and PGF20t was administered intramuscularly. Artiļ¬cial insemination was carried out 48 and 72 hours after CIDR removal. It could be concluded as for Anestrus where a single deviated dominant follicle persists for longer duration Progesterone with estradiol therapy may be used to induce estrus.en_US
