Breeding history showed that the animals were inthe advanced stage of gestation, i.e 2-3 weeks prior to parturition. On routine clinical examination, they warranted in certain antepartum complications like were found carrying live foetus and no other vagino cervical prolapse, hydroallantois or hydramni.
