[Clinico-chemical blood values in newborn calves. 1. Effects of some internal and external conditions].
In a large dairy cattle herd blood samples taken by venipuncture in newborn calves within 0 to 12 hours after delivery were analysed for hematocrit and fifteen other variables. The time of birth and the time of blood sampling and of first colostrum supply were recorded as well as body weight, sex and breed of the animals. Blood sampling in dairy cows was performed in the course of a herd health programme. The effects of the above-mentioned factors on the blood values of calves were investigated. Comparing the blood values of the pregnant cows with those of their newborn calves led to the result that in calves the measures were higher than (Hkt, Thyroxine), equal to (urea, P, Ca, Zn, Mg, K, Na, TIBC) or below (total protein, albumin, gammaglobulin, cholesterol, coeruloplasmin, Fe, Cu) those of their dams. There was great scattering of the concentrations of Zn, Cu, Mg, Fe, TIBC, total protein, albumin and in hematocrit. Uptake of colostrum caused the concentration of Mg, total protein and gammaglobulin to increase and those of albumin and hematocrit to decrease, leaving the levels of P and blood urea unchanged.
