Blood serum transferrin concentration in cattle in various physiological states, in veal calves fed different amounts of iron, and in cattle affected by infectious and non-infectious diseases.
Transferrin (Tf) concentrations were determined in cattle in various physiological states, in energy-deficient (ketotic) cows, in situations of several acute and chronic infections, after endotoxin administration and in animals with bovine leucocyte adhesion deficiency (BLAD). Tf concentrations varied between 1.5 and 8.5 g/l and in healthy animals were in the range of 2.0 and 6.6 g/l. Tf concentrations in adult animals were smaller than in young animals and increased in veal calves with iron deficiency above 8 g/l, resulting in a negative correlation between Hb and Tf. In veal calves total iron binding capacity (TIBC) and Tf concentration were rather closely correlated (r = 0.63). Chronic infectious diseases (such as paratuberculosis) were characterized by relatively low Tf levels (below 2 g/l), while during acute infections, after endotoxin-administration and during ketosis Tf concentrations were not changed.
