Quantitative comparison between serum components and somatic cells in bovine quarter milk.
Quantitative comparisons between serum components and somatic cells in 202 bovine quarter milks collected at 3 dairy farms were conducted. Detection of serum components was carried out by an immunological technique, and cell counts were calculated by Breed's method. A high correlation (r = 0.77) between cell counts and gamma-globulin contents was demonstrated, while correlation between cell counts and serum albumin was not close (r = 0.45). In a comparison between cell counts and gamma-globulin contents, 19 (65.4%) out of 29 milks containing over 500,000 cells/ml had gamma-globulin less than 1.138 mg/ml, which was also seen in 97% of 172 milks having less than 500,000 cells/ml. From these results, it was suggested that the gamma-globulin content of milk might be of use for differentiating normal milk from abnormal ones.
