Reactions of non pregnant and and of cattle at different stages of pregnancy from the Holstein Friesian breed (HF) and from the old type German black and white breed (DSB) exposed to transport stress: variation and individual reaction patterns of hormone metabolic and hematologic variables

Breeding animal transports between parts of our institute were used assessing effects of age of animals, of breed, of their functional state and of individual specificity of reaction patterns using peripheral venous blood samples. Increased mean values of Hb, Hk, body temperature, total protein, albumin, FT4, T4, FT3, T3, cortisol, adrenaline and decreased ones of body weight, Pa, Fe, noradrenaline were found after transport stress. Comparing age matched groups of DSB and HF breed higher concentrations of total protein, creatinine, lactate, cortisol, FT4, T3 and FT3 and lower ones of albumin, blood urea and Fe could be observed in animals of DSB breed before and after transport. Strong correlations existed on 14 variables within animals before and after transport stress meaning there could be individual specificity of some blood parameters.
