In the present paper, we determined the mitochondrial DNA sequence 539bp of the high variable I D-loop regions(mtDNA HVS-I) for 243 domestic fowls 19 were Wugu (or black-bone chicken and 8 non-wugu breeds/races and 38 red jungle fowls (Gallus. Gallus. spadiceus and Gallus. Gallus. jabouillei). We also sequenced 289bp mitochondrial DNA of Cyt-b for 5 red jungle fowls; D-loop region (mtDNA HVS-I)for 19 individuals Guinea fowl and 18 individuals mule chickens (Guinea fowl $ x Wugu chickens^ ) respectively; mtDNA HVS- II of D-loop region for 34 individuals of domestic fowls and red jungle fowls in 690bp and the MC1R code gene in 945 bp.

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.
