Unsuccessful artificial insemination (AI) as well as embryo mortality are the main causes of the reproductive and economic losses of the buffalo breeding. This study was performed to evaluate some metabolic and oxidative aspects related to the outcome of artificial insemination. In 100 buffalo cows, pregnancy associated glycoprotein was assessed to confirm pregnancy. Blood concentration of homocisteine (Hcy), vitamin E and malondialdehyde were analyzed in 35 animals during the first 9 weeks of pregnancy. Results indicated a critical period exists between third and fourth week after insemination. In this period, an oxidative stress occurs which in turn might be responsible for embryo damage. Moreover, Hcy increased in pregnant buffaloes while showed low levels in buffaloes with unsuccessful AI.

Abstract
Unsuccessful artificial insemination (AI) as well as embryo mortality are the main causes of the reproductive and economic losses of the buffalo breeding. This study was performed to evaluate some metabolic and oxidative aspects related to the outcome of artificial insemination. In 100 buffalo cows, pregnancy associated glycoprotein was assessed to confirm pregnancy. Blood concentration of homocisteine (Hcy), vitamin E and malondialdehyde were analyzed in 35 animals during the first 9 weeks of pregnancy. Results indicated a critical period exists between third and fourth week after insemination. In this period, an oxidative stress occurs which in turn might be responsible for embryo damage. Moreover, Hcy increased in pregnant buffaloes while showed low levels in buffaloes with unsuccessful AI.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
