Respiratory problems of newborn calves.
Cardiopulmonary development of fetus is a timely event that proceeds to the point that birth can take place. Calves may be born premature, and because of surfactant deficiency, develop the respiratory distress syndrome. More research needs to be done on fetal lung development in calves to determine the age when maturity has been reached for compatibility with extrauterine life. Also, more specific therapy regimens need to be developed that will enhance lung development. The birthing process is a major event that must proceed in a timely fashion. Any delay in delivery will compromise further the already hypoxic fetus. Practitioners need to recognize the severely hypoxic/ asphyxiated calf and be prepared to therapeutically support the cardiopulmonary systems.
