Polycyclic aromatic hydrocarbons (PAH) are present throughout the global environment and are produced naturally and by activities of humans. Effects of PAH on birds have been determined by studies employing egg injection, egg immersion, egg shell application, single and multiple oral doses, subcutaneous injection, and chemical analysis of field-collected eggs and tissue. The four-to six-ring aromatic compounds are the most toxic to embryos, young birds, and adult birds. For embryos, effects include death, developmental abnormalities, and a variety of cellular and biochemical responses. For adult and young birds, effects include reduced egg production and hatching, increased clutch or brood abandonment, reduced growth,...
Reproduction in nondomestic birds: Physiology, semen collection, artificial insemination and cryopreservation
Pioneering work by Quinn and Burrows in the late 1930s led to successful artificial insemination (AI) programs in the domestic poultry industry. A variety of species specific modifications to the Quinn and Burrows massage technique made AI possible in nondomestic birds. Massage semen collection and insemination techniques span the entire range of species from sparrows to ostriches. Also, cooperative semen collection and electroejaculation have found limited use in some nondomestic species. Artificial insemination produces good fertility, often exceeding fertility levels in naturally copulating populations. However, aviculturists should explore other ways to improve fertility before resorting to AI. Artificial insemination...
Both the Japanese and Bobwhite quail are important species for biomedical, toxicological and basic biological research. In view of their rapid maturation, high reproductive rate in captivity, and other physiological characteristics, these species have been and will continue to be used successfully as model avian species. This short reviews describes caging, environmental, and feed requirements for Japanese and Bobwhite quail maintained in captivity. Information on egg collection, incubation, care of young, handling, blood collection and common diseases are discussed.
