Hydroallantois and hydramnios in bovine cloned pregnancies
Hardisky, Denise M.
A two year old, female crossbred Angus influenced heifer, was seen on a bovine exclusive externship. The heifer was 223 days pregnant with a cloned pregnancy. On presentation, the patient was bright, alert, and responsive. On physical exam, notable symmetrical bilateral abdominal distension was observed. Vital signs were within normal limits with no evidence of respiratory distress. On rectal palpation a firm, fluid-filled uterus was palpable. A calf was not palpable. Due to the comfort level of the heifer, she was closely monitored in the hospital pen. Hydrops (hydroallantois and hydramnios) is a very important syndrome in bovine assisted reproductive techniques including somatic cell nuclear transfer (SCNT). Hydroallantois is a more common condition than hydramnios and is a result of dysfunction of the placenta, resulting in an increased production of chorioallantoic fluid (1). Hydramnios is less common and usually results from an abnormality of the fetus (1). This presentation will focus on the diagnosis of uterine hydrops, treatment, and prognosis. The differences between the two syndromes will be highlighted. A brief history and introduction to SCNT cloning and its importance in agriculture will also be presented.
