    Study Notes

    • Smoke inhalation can trigger removal of birds due to various behavioral and physiological reasons.
    • Displaced aggression or frustration, stressors in the environment, alteration of routine, and sexual frustration in imprinted birds are potential causes for birds being removed.
    • Macaws display mate preening behavior.
    • No single treatment fits all birds, a comprehensive medical investigation is necessary to identify health factors.
    • Tests include haematology and biochemistry, radiography, chlamydophila serology, and diet and management assessment.
    • Pet poultry species include ex-battery hybrid hens, pedigree chickens, waterfowl, turkey, peafowl, guineafowl, and ratites.
    • Egg peritonitis is a broad term for inflammation of a bird's reproductive tract and coelomic cavity, the most common reason for chicken presentations.
    • Aetiopathogenesis of egg peritonitis can be due to failure of a follicle to move into the infundibulum, external trauma leading to oviduct rupture, or accumulated oviductal damage causing narrowing.
    • Clinical signs of egg peritonitis include none in early disease, lethargy, anorexia, weight loss, ascites, and predisposition to other pathogens.
    • Diagnosis is based on clinical examination, radiography (rarely), ultrasonography, and eliminating differentials such as egg binding, aspiration, or clear to orange fluid.
    • Management includes initial stabilization with oxygen therapy and subcutaneous fluids, conservative management with anti-inflammatories, and long-term control through cessation of reproductive activity, euthanasia, salpingectomy, or endocrine manipulation.
    • Preventative measures include optimizing husbandry, quarantine and vaccination protocols, controlling infectious factors, providing shelter, and selecting lower production breeds.
    • Marek's Disease is caused by an oncogenic Gallid herpesvirus, can affect chicks from 12-20 weeks, is neurotrophic and most commonly affects the sciatic nerve causing leg weakness and paralysis.
    • Mycoplasma gallisepticum is a respiratory and reproductive infection caused by a bacterium, often seen after the introduction of new birds, and can lead to severe disease through co-infections.
    • Internal parasites, such as coccidia, are common in poultry and can cause severe disease and reduce productivity.
    • The most pathogenic species of coccidia are Eimeria necatrix and E. tenella.
