Histology of the male gonad of adult Khaki Campbell duck (Anas platyrhynchos domesticus) in Bangladesh

Abstract

The current research was designed to investigate the histological description of testes of adult (6 months old) Khaki Campbell duck in Bangladesh. The study was conducted in the Department of Anatomy & Histology, Bangladesh Agricultural University, Mymensingh. The experimental Khaki Campbell ducks (Anas platyrhynchos domesticus) were collected from poultry farm of Bangladesh Agricultural University, Mymensingh, having apparently good health and devoid of any external deformities. The testes were collected immediately after ethical killing of the birds for histological observations. The collected tissue samples were then processed and stained with Hematoxylin & Eosin (H & E) stain for histological observations. Each testis was covered by a connective tissue capsule. There were no thick connective tissue stripes dividing the testis into lobules. The stroma of the testis possessed no mediastinum. Leydig cells were commonly found in groups within the connective tissue which filled the spaces between the seminiferous tubules. Germ cells and Sertoli cells constituent the main component of the seminiferous epithelium. This basic histological feature may help to explore the molecular changes of adult testes of Khaki Campbell duck.
