摘要: It has, I believe, been often remarked, that a hen is only an egg’s way of making another egg. (Samuel Butler, 1835-1902) Antibodies the IgG class are selectively transported across oviduct from hen’s circulation to egg yolk. From there they transferred embryo and help provide systemic immunity essential for survival during first few weeks chicken’s existence in microbially hostile environment. immunoglobulin (Ig) M A classes largely confined white ingested by ensure local gastrointestinal early life. There substantial rapidly increasing literature concerning potential application yolk-derived antibodies both diagnostic therapeutic purposes.
