[Haptoglobin in domestic mammals. V. Plasma haptoglobin level in cattle under pathological conditions].

The haptoglobine concentration in the blood plasma of cattle tends to rise to more than 10 mg/100 ml in the presence of acute inflammation anywhere in the organism. They were 40 mg/100 ml and above in the presence of traumatic reticuloperitonitis. The absence of haptoglobin multiplication in the plasma is a high-probability indicator to the absence of that inflammatory process. chronic inflammation will only in exceptional cases entail plasma-haptoglobin multiplication. Concentrations will not be pathologically increased in cattle with positive reaction to haematological testing for leucosis.
