1928 Riddle & Tange in Amer. Jrnl. Physiol. 86 266 It was thought that observations on these processes in birds deprived of the bursa should supply further light on this problem. As a descriptive term for the process of extirpation of this bursa, we shall introduce and use the word ‘bursectomy’.
1956 Poultry Sci. 35 224/1 An experiment designed to study the effect of bursectomy.
1968 Nature 19 Oct. 294/1 Bursectomy was achieved either surgically on 1 day old chicks, or hormonally by injecting 6/7 day old incubated eggs with..testosterone propionate.
1974 Sci. Amer. Nov. 60 A small portion of chicks subjected to this ‘hormonal bursectomy’..are tolerant of foreign skin.
