A sodium sulfite-precipitation test utilizing 3 concentrations of sodium sulfite to evaluate the immune status of neonatal calves allowed scoring of serum immunoglobulin concentrations as less than 5 mg/ml, 5 to 15 mg/ml, and greater than 15 mg/ml. Of the 54 estimations for serums that contained greater than 5 mg/ml, 96% were correct; of the 30 estimations for serums that had between 5 and 15 mg/ml, 90% were correct; and of the 42 estimations for for serums with greater than 15 mg/ml, 93% were correct. It was concluded that this test can be used under field conditions to evaluate the immune status of neonatal calves.
