Abstract :
In farm animals, pregnancy is diagnosed by using visual, clinical and laboratory techniques. Clinical techniques, used for pregnancy diagnosis, are vaginal examination, rectal examination, radiography and ultrasonography. Vaginal examination is mostly relaying on visual criteria and pregnancy is diagnosed late with a lower accuracy. Rectal examination is used in every stage of pregnancy, preferentially in farm animals with a large pelvic cavity and it gives accurate results. It is not used for pregnancy detection in animal with a small pelvic cavity, like sheep and goats. Instead, recto-abdominal examination in sheep and bimanual examination for goats are preferred. Radiography is not used in cow and rarely used in sheep and goat for pregnancy diagnosis. The accuracy of this technique increases only towards the second half of the gestation and the viability of the foetus can not be known. All of the clinical techniques, listed here, are applicable in farm condition except radiography. The best technique for pregnancy diagnosis in cow is B-mod ultrasonography. Using this technique, pregnancy is diagnosed earlier, accurately and more reliably without having too much experience. Also, it gives reliable information about the age, sex, viability, growth and the number of foetuses in the uterus.
