"Failure of passive transfer" of immunity (also called "FPT") occurs when a calf fails to absorb an adequate quantity and quality of immunoglobulin prior to closure of the intestine that occurs at approximately 24 hours after birth. FPT has been linked with increased calf morbidity (sickness), mortality (death), and a reduction in calf growth rate and feed efficiency. It is estimated that of the calf deaths occurring in the first 3 weeks of life, approximately one-third are due to inadequate colostrum intake.
