TLDR
This experiment shows colostral immunoglobulin concentration is a major factor in the rate of immunoglobeulin absorption and the amount of absorption when it is fed to newborn calves, and when compared on equal mass, the amountof colostrum fed, 1 or 2 liters, had less influence on immunoglOBulin absorbed than did concentration.Citations

Immune function across generations: integrating mechanism and evolutionary process in maternal antibody transmission
TL;DR: Integration of the proximate mechanisms of maternal antibody transmission with evolutionary theory on maternal effects affords an important opportunity to unite mechanism and process by focusing on the links between genetics, environment and physiology.

Growth factors and antimicrobial factors of bovine colostrum
R. Pakkanen,J. Aalto +1 more
TL;DR: Bovine colostrum is the first natural food produced by female mammals during the first 24–36h directly after giving birth and is known to contain insulin, transforming growth factor β and related growth factors, but their function is not fully understood.

Nutrient and immunity transfer from cow to calf pre- and postcalving.
J.D. Quigley,J.J. Drewry +1 more
TL;DR: In this paper, the authors consider the potential effects on the calf prior to and after calving and suggest that low protein diets may increase the incidence of respiratory acidosis, which may impair the acquisition of passive immunity.

Management and production factors influencing immunoglobulin G1 concentration in colostrum from Holstein cows.
TL;DR: Weight of first milking colostrums and lactation number of the cow were the most significant discriminators between colostrum of low and high IgG1 concentration.

Composition of colostrum from dairy heifers exposed to high air temperatures during late pregnancy and the early postpartum period.
TL;DR: High air temperatures during late pregnancy and the early postpartum period markedly affected the composition of colostrum from primiparous dairy cows.

Immunochemical quantitation of antigens by single radial immunodiffusion
TL;DR: By standardizing the technical conditions of the experiment it is possible to use this principle for the immunochemical determination of antigens, and the lower limit of the method was found to correspond to 0·0025 μg of antigen, and to an antigen concentrations of 1·25 μg per ml.

Applied Linear Statistical Models
TL;DR: The authors used an applied approach with an emphasis on the understanding of concepts and exposition by means of examples, and sufficient theoretical information is provided to enable applications of regression analysis to be carried out.

TL;DR: The results by the antibody-agar plate method are similar to those obtained by the isotopic immune inhibition technique, except for the serum IgA and Type K (I) and Type L (II) immunoglobulin levels.
