Responses of broiler chickens orally challenged with Clostridium perfringens isolated from field cases of necrotic enteritis.
TL;DR: Although no overt necrosis of the intestinal mucosa typical of field cases of NE were observed in the present study, the birds challenged with C. perfringens showed strong inflammatory reaction to the introduced pathogens, suggesting newly emerging patterns of sub-clinical enteric disorders in contemporary strains of poultry.

Feeding high levels of lupine seeds to broiler chickens: plasma micronutrient status in the context of digesta viscosity and morphometric and ultrastructural changes in the gastrointestinal tract
TL;DR: The enlargement of the intestinal tract was consistent with physiological hyperplasia and not pathological remodeling and hypertrophy, and it is apparent that the bioavailability of these micronutrients from lupine diets is not compromised.

The aetiology of hypoxaemia in chickens selected for rapid growth.
TL;DR: Key factors associated with the development of hypoxaemia in fast-growing broilers include high demand for oxygen as evidenced by high oxygen ER; inadequate cardiac output to fulfill the higher oxygen demands, leading to severe depletion of O(2) in mixed venous blood; and elevated intrapulmonary shunt fraction and possibly dead space associated with specific pathological and anatomical characteristics within the lung.

Biochemical and physiological weaknesses associated with the pathogenesis of femoral bone degeneration in broiler chickens.
A. A. Olkowski,Bernard Laarveld,C. Wojnarowicz,M Chirino-Trejo,Dean Chapman,Tomasz W. Wysokinski,Luca Quaroni +6 more
TL;DR: Findings indicate that femoral bone degeneration is associated with structural changes occurring in both inorganic and organic matrix of the bone, but insufficiency in protein metabolism is most probably a primary aetiological factor in the natural history of femoralBone degeneration.

Comparative study of myocardial high energy phosphate substrate content in slow and fast growing chicken and in chickens with heart failure and ascites.
TL;DR: The changes in heart high energy phosphate profile in broilers suggest that the energy demand of the heart during a rapid growth phase may exceed the bird's metabolic capacity to supply adequate levels of highenergy phosphate substrate.
