Scoliosis developed in 55 per cent of sexually mature birds (68 per cent of male and 46 per cent of female birds) in a highly inbred line of chickens originally produced from white Leghorns. The curve could first be detected at five to six weeks of age and progressed until spontaneous fusion of the thoracic vertebrae occurred. Studies of these chickens

Evaluation of the heterophil/lymphocyte ratio as a measure of stress in chickens.
Avian diseases, 1983The number of lymphocytes in chicken blood samples decreased and the number of heterophils increased in response to stressors and to increasing levels of corticosterone in the chicken feed.

Aphagic chickens have been produced with electrolytic lesions placed stereotaxically in the diencephalon. These chickens were maintained by introducing food into their crops through a tube. They were inactive and lost much of the ‘nervous’ temperament of White Leghorn chickens.

Campylobacter infection in chickens modulates the intestinal epithelial barrier function
Innate Immunity, 2015Asymptomatic carriage of Campylobacter jejuni is highly prevalent in chicken flocks. Thus, we investigated whether chronic Campylobacter carriage affects chicken intestinal functions despite the absence of clinical symptoms. An experiment was carried out

The chicken has long been an important model organism for developmental biology, as well as a major source of protein with billions of birds used in meat and egg production each year. Chicken genomics has been transformed in recent years, with the characterisation of large EST collections and most recently with the assembly of the chicken genome ...

The Autopsy of Chicken Nuggets Reads “Chicken Little”
The American Journal of Medicine, 2013To determine the contents of chicken nuggets from 2 national food chains.Chicken nuggets have become a major component of the American diet. We sought to determine the current composition of this highly processed food.Randomly selected nuggets from 2 different national fast food chains were fixed in formalin, sectioned and stained for microscopic ...

Pathogenicity of chicken anaemia agent in bursectomised chickens
Avian Pathology, 1988Bursectomised (Bx) chickens, but not intact chickens, developed anaemia when inoculated with chicken anaemia agent (CAA) at 2 weeks of age. No antibodies against CAA were produced in the Bx chickens and CAA was persistently recovered from them. In contrast, CAA disappeared from the intact chickens with the development of high titres of antibody. It was

The Kinetics of the Conversion of Chicken Pepsinogen to Chicken Pepsin [PDF]
European Journal of Biochemistry, 1973 The kinetics of the conversion of chicken pepsinogen to chicken pepsin was studied at 25°C by following the appearance of peptic activity using a pH‐static method and by following the changes in the fluorescence emission of the protein. It was found that in pH range of 2–4 both processes were first‐order reactions, and that the change in fluorescence ...

Vox Sanguinis, 1964
SummaryIn the chicken twelve autosomal blood group systems are known. The A and E systems are closely linked and the D and H and perhaps A and J systems probably loosely linked. The B system is the most complex and has more than 30 groups within it. Antisera to B antigens are usually high cross reactive.
