TLDR
The presence of immunoglobulins and antibodies were investigated in the fertile hen's egg during embryogenesis and moderate antibody levels were detected in the amniotic and allantoic fluids from the 12th to the 18th days of incubation.Abstract:
The presence of immunoglobulins and antibodies were investigated in the fertile hen's egg during embryogenesis. The egg yolk, egg albumin, amniotic and allantoic fluids, chick embryo serum and intestinal contents were examined for the presence of immunoglobulin and level of antibodies.
Immunoglobulin G was not detected in fresh egg albumin, but appeared in the albumin from the 4th day of embryogenesis and persisted through the 16th day. The antibody profile of egg albumin during embryogenesis attained two peaks, which were separated by a trough on the 8th day of embryogenesis. The immunoelectrophoretic pattern of albumin IgG was different from that of egg yolk IgG.
The IgG of chick embryo serum was of γ2 mobility on the 12th day of incubation and shifted gradually to the full range of γ1 and γ2 mobilities on the 20th day of incubation. Egg-transmitted antibodies appeared on the 12th day of incubation and attained peak values on the 16th day of incubation.
Moderate antibody levels were detected in the amniotic and allantoic fluids from the 12th to the 18th days of incubation.read more

TL;DR: The dual mode of transfer found for maternal Ig of different classes in the fowl is compared with the transfer of maternal immunity in mammals.

Maternal Antibody Transfer from Dams to Their Egg Yolks, Egg Whites, and Chicks in Meat Lines of Chickens
TL;DR: IgY levels, total or antigen-specific, in the dams' plasma or eggs were found to be a direct indicator of maternal antibody transfer to the chicks' circulation, with an expected percentage transfer of approximately 30%.

Early Feeding and Development of the Immune System in Neonatal Poultry
TL;DR: Data indicate that provision of the optimum balance of nutrients immediately after hatch result in heavier bursa weights, earlier appearance of biliary IgA and germinal centers, and an improved resistance to disease challenge.

Quantitation of maternal-fetal IgG transport in the chicken
TL;DR: Quantitative and temporal features of maternal-fetal transport of IgG in the chicken have been determined by means of a sensitive and specific radioimmunoassay, suggesting that IgG uptake occurs predominantly in the last few days before hatching.

Effect of Campylobacter-Specific Maternal Antibodies on Campylobacter jejuni Colonization in Young Chickens
TL;DR: It is indicated that anti-Campylobacter MAB contributes to the lack of Campylobacteria infection in young broiler chickens in natural environments and this work provides further evidence supporting the feasibility of development of immunization-based approaches for control of Campyobacter infection in poultry.

TL;DR: The conclusion is drawn that cells producing IgM antibodies can form both clusters and plaques, and evidence is presented that cluster formation does not always depend on the excretion of antibodies.

On the transference of bacterial antibodies from the hen to the chick.
TL;DR: The results suggest that some of the antibody in egg yolk is formed in the follicular epithelium of the developing ovule or in the yolk material itself, and a passive immunity to Salm.

TL;DR: Some evidence is presented which suggests that a selective concentration of 7Sγ2-globulin occurs during the process of yolk formation, which would indicate that immune antibodies are passed into the yolk and into the sera of hatched chicks.

Ovalbumin and other water-soluble proteins in avian yolk during embryogenesis
Z. Saito,W. G. Martin +1 more
TL;DR: The proportion of water-soluble protein in egg yolk increased markedly after 12 days' incubation, concurrent with the appearance of a new fraction that evidently entered from the egg white, and the tyrosine–tryptophane and phosphorus–nitrogen ratios were similar to those of authentic ovalbumin.
