Main arteries to the female reproductive organs in the helmeted guineafowl (Numida meleagris)



The helmeted guineafowl, Numida meleagris, is a member of the Galliformes (King & McLelland, 1975). This order includes the domestic fowl, Callus domeslicus, which has undoubtedly dominated research studies in poultry production generally. Many of the anatomical studies in birds have been carried out using the domestic fowl, with comparatively little mention of other genera. Although the genera in the Galliformes have very many similarities, few anatomical differences have been shown to exist. For example, Crowe & Crowe (1979) have found some striking differences between the blood supply to the head and neck of the guineafowl and the domestic fowl.

The guineafowl has become a popular poultry bird in Nigeria, and has been said to rank second to the domestic fowl, despite its seasonal breeding pattern. The further improvement of this genus in our poultry production has necessitated increased studies into its nutritional requirements, management procedures and disease prevalence. In line with this improvement is the need for anatomical data on the female reproductive organs as a basis for the breeding and selection programme. The aim of this study is to describe the macroscopic arterial blood supply to the reproductive organs of the guineafowl.
