The immunoglobulin concentration in bovine colostrum should be measured to ensure feeding with sufficient immunoglobulins (≥50 mg immunoglobulin G mL−1). Adequate feeding prevents diseases, promotes development, and has a positive influence on the adult animal. Indirect and direct measurement methods are available for this purpose. Direct measurement methods cannot be easily used in practice; therefore, farmers use indirect methods such as a colostrometer and a refractometer. Many factors influence the immunoglobulin concentration of colostrum; some of them have already been intensively researched. In particular, lactation and temporal aspects play an essential role. Newer aspects such as dry period, seasonal influences, and genetics are gaining importance, but their impact on immunoglobulin content has not been sufficiently investigated. Developments are still needed, especially in data management. This review analyzes the outcome of different studies on the indirect and direct measurement methods and discusses different factors influencing the immunoglobulin concentration of bovine colostrum.

For years measurement of proteins is a routine method in medical laboratories. The principles of these methods are discussed. The use of laser beam for detection of immunocomplexes is a new method for measuring proteins. The principles of apparatus working with laser beams are demonstrated. The special physical qualities of laser beams achieve a high sensitivity in laser nephelometry and laser photometry. This new method is proved to be suited for daily determination of proteins on account of data of correlations and precisions.

In the first three weeks after kidney transplantation the patients were examined for daily changes in immunoglobulin levels. Only very seldom was a decrease of IgM detected in our patients who had undergone splenectomy. During half of the rejection crisis there were indeed short periods of increase (spikes) in immunoglobulins. These were observed always before or concomitantly with the clinical diagnosis of a rejection reaction. In order to determine the connection between immunoglobulin-spikes and an approaching rejection episode the general one-sided binominal test was used. A significant relation was established between IgM peaks and an approaching rejection crisis. No such relation could be found for the IgA peaks observed. The IgG globulins showed no consistent pattern during a transplantation rejection. A persistent fall of the IgG globulins was noted in the first ten days after renal allograft with the immunosuppressive regimen of an initial gramme of methylprednisolon and high dosage of azothioprine. A good correlation was observed with the simultaneous depression of serum albumin concentrations. As losses of protein in urine are minimal (already confirmed by other authors), it must be assumed that in the first place a high rate of catabolism and a restriction in the protein synthesis is responsible for the decrease in the IgG globulins and the serum albumins.
