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

Testing the Regumate Product in Association with Other Hormonal Products for Oestrus Synchronization in Gilts

The aim of this study was to evaluate the effect of Regumate® product in association with other hormonal products as a method for oestrus synchronization in gilts. The study was carried out between October 2016 – March 2017 in a private unit in Cluj County, and involved 16 gilts, 8 months of age. The synthetic progesterone Regumate was fed daily at 20 mg Altrenogest/gilt for 18 days. For all animals, 24 hours after cessation of progesterone treatment a PMSG hormone (Folligon) was administered (500 IU/gilt). After a rest period (48 hours) gilts received one injections of hCG hormone (Chorulon), 500 IU/gilt. Gilts were checked for oestrus twice daily and were artificially inseminated. Oestrus occurred on average 5 days after completion of treatment. All gilts expressed signs of oestrus between 24 and 30 hours with a mean value of 28.37 hours. Pregnancy rate was 75% after second insemination. The mean value of farrowed piglets was 10.16 and the average number of weaned piglets in was 9.58. Altrenogest, the active ingredient in Regumate® is effective for regulating the oestrus of gilts in commercial pig farms
