Postnatal Changes of Serum Components in Japanes Black Calves

Abstract

Serum components were examined in 112 Japanese Black calves aged 1 to 73 days. No significant correlation was observed between ages and serum free fat acids, triglyceride or glucose levels. However, significant linear correlations were seen between ages and concentrations of serum total protein, β-globulin and γ-globulin. The levels of albumin, total cholesterol and phospholipid increased till 20 to 30 days of age, whereas those of α-globulin, sialic acid and BUN decreased till 10 to 30 days after birth.
