The Presence of Immunoglobulin in the Bursa of Fabricius ,
Poultry Science, 1967 Abstract Three-week-old birds were immunized with 40 mg. bovine serum albumin (BSA) per Kg. body weight. The bursa of Fabricius was removed 30 minutes after BSA injection and from another group of birds at 24-hour intervals for 5 consecutive days. The bursa was frozen −25°C. and sectioned in a cryostat (−25°C.) at 4 mμ.

The Bursa of Fabricius and Antibody Production
Poultry Science, 1956 Abstract The bursa of Fabricius is a structure peculiar to Aves. It is a blind sac connected by a small duct to the dorsal part of the cloaca. Often nicknamed “the cloacal thymus,” the function of the bursa is believed to be similar to that of the thymus (Riddle, 1928; Taibel, 1938).
