  • Title: [Effect of different systems of colostral nutrition on the level of immunoglobulins in the blood of calves].
    Author: Mensík J, Dressler J, Franz J, Pokorný J.

    Abstract:
    New-born calves, artificially fed colostrum or native colostral whey, either dried or preserved by another method, had good health and good weight gains (between 0.05 and 0.60 kg). No greater differences were observed between the groups of calves given three times the colostrum of their mothers, calves given mixed colostrum, and calves fed colostral whey powder. In all groups only individual differences in IgG content in the blood serum were observed after 48 hours from birth. Hypogammaglobulinaemia occurred in individual cases both in calves given small amounts of colostrum or colostral whey and in calves given sufficient quantities. The time that had elapsed from birth to the first drinking did not exert any greater influence upon the IgG level in the blood; the decisive factor was the amount of colostrum taken in by the calf in the first dose. The rate of the absorption of IgG1, IgG2, IgA, and IgM from colostrum and the concentration of the immunoglobulins in the serum depended on the quantity of colostrum in the first dose and were not influenced to any greater degree by the amount of colostrum given to the calves in further doses. The amount of IgG in the blood serum of calves corresponded approximately to the level of colostral antibodies to the virus PI-3. The antibodies to the virus PI-3 and small quantities of IgG were observed also in the serum to new-born calves before drinking colostrum.
