Abstract:
Blood serum concentrations of protein, albumin, prealbumin, transferrin, amino acids and urea were measured in 31 healthy cows 0 to 6 weeks before and 3 to 8 weeks after parturition. In comparison to the precalving values the concentrations of albumin, prealbumin and transferrin were all lower after parturition. Alanine, glutamine, leucine, methionine, serine, and urea concentrations were also lower after calving. Multiple correlation analysis between plasma protein and amino acid concentrations reveals that the synthesis of export proteins in liver may be reduced due to limitation in amino acid availability.
