Abstract

Postnatal development of the Bursa of Fabricius was studied in Nigerian local and Isa brown chickens. The local chickens attained maximum weight (.94g) at week 7 and week 13 for cockerels and pullet respectively while the Isa brown attained maximum weight (a.02g and 3.12g) at week 1 and 17 for cockerels and pullets respectively. Regression appeared earlier in local chickens before the Isa brown. These growth patterns may have effect on their resistance to some infections.
