Dystocia Associated with Abortion due to Twin Pregnancy in Pluriparous Murrah Buffalo

In general, multiple calvings are considered more difficult than single ones in bovine (Zaborski et al., 2009). Twins are also reported to reduce the breeding efficiency of dairy as well as beef animals (Cobanoglu, 2010). Twin calves are known to be lighter in weight as compared to single births (Gregory et al., 1996). However, the higher incidence of dystocia with twin births is due to malpresentation of one fetus (Gregory et al., 1996) or simultaneous presentation of both fetuses (Kirkpatrick, 2002). Also, the gestation length in case of twin pregnancy is considered less as compare to single pregnancy which sometimes terminates early in the third trimester and may mimic an abortion and are mostly associated with dystocia (HosseinZadeh, 2010). Twins can either be monozygotic which are always of same sex or dizygotic which can be of either sex. The present case reports similar findings, where abortion due to twin pregnancy in eighth month of gestation was observed in a pluriparous murrah buffalo and its successful clinical management has been discussed.
