[Determining trends in changes of total proteins and immunoglobulins in the blood serum of calves in the first few days of their life].
671 samples of calves' blood serum taken from the 2nd to the 6th day after birth were examined to determine the level of total protein and immunoglobulins. When establishing the trends (linear, square and cubic) of the significance of coefficients and the quality of approximation there was considered the day after birth on which blood was sampled as well as the feeding season. Ig were proved to show a clear regressive trend, i.e. the later was the day of sampling beginning from the second day of life, the lower was the level of Ig. The level of total protein did not show any trends of dependence on the day of life, and analysis of the trend carried out with use of higher order multinomials pointed to randomness of the phenomenon. In the pasture period (summer) the trend for Ig is high-significantly linear, while in the winter period it is non-linear. As for Bc of blood serum, the phenomenon was found to be random.
