Abstract:
A study was conducted to find out the etiologies of 4 fetal mummifications in jersey crossbred cows, where 2 cases (case No. 1 and 2) belonged to one farms and rest 2 (case No. 3 and 4)were from two different farms of distant places. All the animals were within the 8 to 9 months pregnant without any physical signs of advancement of pregnancy. Based on clinical gynecological and USG findings the cases were provisionally diagnosed as mummification of fetus. The BVDV infection was confirmed in all the four cows housed under same roof with RT-PCR analysis. The two cows from two different farms were free from infections. Out of all the 6 cases 4 cows were treated successfully with IM injections of 500 mcg Cloprostenol and 4mg of Estradiol benzoate simultaneously. In case of other two cows Epidosin injection (Valethamate Bromide) @ 1ml/ 20 kg body weight, IM as single dose along with feathering at the os of the cervix were required in addition to the Cloprostenol and Estradiol. In case number 1 and 2 complete cervical dilatation was observed around 72 hours post treatment and mummies were presented partially in the vaginal cavity and cervical canal. However, in long standing case No.3 and 4, additionally Valethamate Bromide injection was required for complete dilatation of cervix where manual traction was required for expulsion of the mummies. All the four mummies were expelled out manually with gentle traction without any complications to the cows.
