Ultrastructure Of Spermatozoa From Domesticated Birds: Comparative Study Of Turkey, Chicken And Guinea Fowl, R. J. Thurston, R. A. Hess
Scanning Microscopy
Typical for non-passerine birds, the spermatozoa of the turkey, chicken and guinea fowl were vermiform with a maximum width of 0.5-0. 7μm and lengths of 90μm for chicken sperm, and 75-80μm for those of the turkey and guinea. An acrosome, nucleus, midpiece and flagellum could be distinguished by SEM.
The acrosomal cap projected over a perforatorium surrounded by granular material. At its base, the cap encircled apical projections of the nucleus. The nucleus consisted of dense chromatin, and formed a concave implantation fossa where it joined the midpiece of the tail. For turkey and chicken spermatozoa, the neck region of …
