Abstract

The levels of the serum and colostral total protein and immunoglobulins of the Korean native cows immediately after parturition and colostrum-conferred passive immune status of the Korean native calves were studied, and the results obtained were summerized as follows: The mean total protein, total immunoglobulin, IgG, IgM, and IgA concentrations in sera of 10 Korean native cows immediately after parturition were $6.8{pm}0.4g/dl$, $24.39{pm}3.41mg/ml$, $19.49{pm}2.70mg/ml$, $4.56{pm}1.14mh/ml$, and $0.35{pm}0.08mg/ml$ respectively. And the mean total protein, total immunoglobulin, IgG, IgM, and IgA concentrations in colostrum were $15.0{pm}1.1g/dl$, $116.13{pm}23.07mg/ml$, $101.51{pm}22.59mg/ml$, $9.46{pm}1.99mg/ml$, and $5.17{pm}1.59mg/ml$ respectively. The mean concentrations of total protein and immunoglobulins in colostrum were 2.1 times to 14.8 times higher than those in serum. The mean concentrations of total protein, total immunoglobuln, IgG, IgM, and IgA in sera from 211 Korean native calves at 2 days old were $6.7{pm}0.9g/dl$, $35.74{pm}9.56mg/ml$, $29.06{pm}8.07mg/ml$, $4.91{pm}2.99mg/ml$, and $1,9{pm}0.99mg/ml$ respectively. Although the calves had been suckled the dam's colostrum, each of calves was considerably various in levels of serum total protein and immunoglobulins and 16.1 percent of the calves were in a state of hypoglobulinemia.
