The A.A. relate about preliminary results from a total of 79 echographic sessions for trans-vaginal pregnancy diagnoses performed on adult pluriparous sheep (48) and goats (3), in late autumn 2004. Each female was subjected to: a) a simple trans-vaginal examination, b) a trans-vaginal examination with lifted abdomen and c) a classic trans-abdominal trans-cutaneous pregnancy diagnosis. In many cases a confirmatory echographic follow-up was repeated a week later or more. For trans-vaginal examinations a 5 MHz, lubricated, convex probe was inserted in the vaginal cavity of the sheep, held in a standing position, and the results were always compared with those obtained by trans-cutaneous examination, in the sitting constrained animal (Tab.1). At first TVAL, on the 51 examined animals 28 resulted pregnant; 18 not-pregnant (two with pathologic uterine collections) and 5 dubious. In spite of our still limited experience, the method including abdominal lifting resulted rapid, early, safe, reliable and easy, therefore the main target of this preliminary note has been to highlight the possibility of checking early pregnancies in small ruminants by TVAL. Smaller echographic probes and more on field experiences are still required for better evaluation of the method and for its extension to younger nulliparous ewe-lambs.
