There is considered that if buffalo cow fertilization has not occurred before entering the barn to be protected against the cold weather of the winter she will get in anestrous state and new heats will delay for a long time. The present paper refers to the results of a prostaglandin PGF2α derivate treatment of 44 cases of after calving anestrous in buffalo cows registered during the housing period in the last 4 years. The buffalo cows aged between 6 and 14 years. The time interval from the former last heat was over 90 days. The treatment consists of intra muscular injection 2 ml of one of cloprostenol derivates. After the first injection 15 buffalo cows out of 44 ones came in heat within 5 days. All of them were two times inseminated artificially at a 12 hours interval. Out of them 12 buffalo cows became pregnant. The other 29 buffalo cows have received a second doze of prostaglandins 11 days after the first treatment. All of them have received blind insemination after 48 and 72 hours from the second treatment. This time 9 buffalo cows became pregnant. Result of the treatment has to be considered as a good one since 24 cows out of 44 treated cases (54, 55%) became pregnant. Perhaps 14 buffalo cows didn’t react to the treatment. Nevertheless the price of the 73 doses of prostaglandin used for the treatment is lower compared to the feeding cost saved by shortening the buffalo cows what became pregnant.
