For screening the appropriate field diagnostic techniques to failure of passive immunoglobulin transfer(FPT) in Korean-indigenous calves, 258 sera was examined by spectinophotometry for total protein(TP) and globulin(Glo), sodium sulfate precipitation test(SSPT), zinc sulfate turbidity test(ZSTT), and single radial immunodiffusion test(sRID). All calves aged within 6-week old. Morbidity and mortality to various diseases, mainly including enteric and respiratory disorders, were 18.9%(49) and 4.2%(11), respectively. FPT was 27,9%(72/258) when the cutoff point of TP was and among them the morbidity and mortality were 27.9% and 6.9%, respectively. FPT was 29.1%(75/258) when the cutoff point of Glo was and among them the morbidity and mortality were 29.0% and 6.9%, respectively. FPT was 13.1%(34/258) when the cutoff point of SSPT was 1+ and among them the morbidity and mortality were 67.6% and 23.5%, respectively. FPT was 19.7%(51/258) when the cutoff point of IgG with sRID was and among them the morbidity and mortality were 41.1% and 11.7%, respectively. In addition, mean concentration of IgG with sRID tested was at 3-day old but at 9-days with . The results of the study were suggested that SSPT for FPT was the relatively reliable and convinient method for evaluating the immune status of calves(P<0.05).
