The Diagnosis of Fetal Sexing in Cattle Using Ultrasound

The purpose of this research was to conduct an ultrasound exam in the interval between 49-120 days of gestation for the determination of fetus sex and to establish the interval when the fetal sexing is possible. The research was carried out in three farms from Transylvania. In farm A were examined 25 animals, in farm B 13 animals and in farm C 11 animals. The diagnosis of the fetal sexing was possible for 35 cases, 14 animals were diagnosed as female and 21 were male. In the interval between 56-65 days of gestation the diagnosis of fetal sexing was established by viewing the genital tubercle and in the interval between 65-90 days of gestation the diagnosis was established by viewing the secondary genital organs. In 14 cases the diagnosis was not set; in 4 cases the conception product has not been sufficiently developed, the genital tubercle was not visible, and in 10 cases the fetus was too big and was impossible to localize the genital organs.
