ABSTRACT
Trans rectal ultrasonography of a 7 year old crossbred Jersey cow was done at weekly interval from 21 to 63 days post artificial insemination. Monochorionic diamniotic monozygotic twins were confirmed on the basis of different amniotic sacs and corpus luteum on one ovary. Color Doppler study was done to assess the vascularity and functional activity of corpus luteum present on the left ovary. Ultrasonography was employed at weekly interval to judge the viability of embryo (up to 42 days), fetus (after 42 days) and late embryonic mortality, if any. Sexing of the twins was done on 56th and 70th day post artificial insemination and two male twins were confirmed on the basis of genital tubercle, median raphe, scrotal and penis impression. With the aid of ultrasonography and color Doppler technique, it is possible to determine the twins’ zygosity and viability.
