Comparative Anatomical, Light and Scanning Electron Microscopical Studies Between Intromittent and Non-Intromittent Typed Phallus of Domestic Goose (Anser anser domestica) and Turkey (Meleagris gallopavo domestica)

The work applied on the phallus of the adult goose and turkey to give knowledge for the phallus functional morphology and the mechanism of copulation of these domestic birds. It helped the surgical interfering of the wild geese and the artificial insemination in the turkey for commercial production. The phallus of the goose and the phallic bodies of the turkey were demonstrated by anatomical, histological, histochemical and scanning electron microscopy to compare the micromorphological features. The goose has an intromittent type phallus. It consisted of inner glandular part and outer cutaneous one. The former lined by mucous secretory cells, while the later cover externally by stratified squamous non-keratinized epithelium. The turkey phallus was a non-intromittent type. It composed of a median phallic furrow on the crest at the ventral vent lip and flanked on either side by lateral phallic bodies. The later lined by stratified squamous non-keratinized and supported by longitudinal oriented skeletal muscle which circular in the furrow between two phallic bodies. Additionally, lymphatic aggregation was observed in phallus of two birds. This study helped in comparative studies and surgical operations.
