Abstract

Despite all efforts during the last four years to improve cloned newborn care, the mortality rate of calf after term is still high, around 50%. Clinical symptoms observed in these cloned calf were related to severe cardiopulmonary disorders like hyperphonese, diastolic and systolic cardiac murmurs associated to dyspnea and crackling lung sounds. Due to the patency of the Foramen Ovale and Ductus Arteriosus, in which causes the mix of arterial and venous blood, the blood oxygenation in these cloned calf is compromised. In addition, cloned calf could also present increased birth weight, hypoglycemia, hypothermia, umbilical cord abnormalities, anemia, and alopecia.
