Silicate Pneumoconiosis in Hens
Journal of Comparative Pathology, 2000Thirteen cases of silicate pneumoconiosis in 3- to 4-year-old hens are described. Ten of the birds were raised in the suburbs of a city near several chalk quarries and two cement-works; the remaining three hens (aged 3 years) had lived in an environment with high particulate pollution from a nearby brick-works in which large amounts of clay were used ...

Experimental Melioidosis in Hens
Journal of Veterinary Medicine, Series B, 1996Experimental intramuscular infection of hens with Pseudomonas pseudomallei, strain 2796 (1 x 10(9) CFU from a 24-h culture) was reproduced. Clinical, paraclinical and pathomorphological findings were followed from 1 to 30 days after challenge. Haemagglutinin titre, bacterial dissemination in the viscera, number of leucocytes, alveolar (aMa) and ...

Seasonal acclimatisation in the hen
British Poultry Science, 19791. The oxygen consumption and body temperature of White Leghorn x Rhode Island Red laying hens, which were being kept in a semi-natural climate, were periodically measured for short periods at ambient temperatures between 2 and 32 degrees C in a suitable chamber. 2.

Phosvitin in the Serum of the Hen
Nature, 1959A PHOSPHOPROTEIN fraction appears in the serum of the hen in association with the onset of laying1,2 or in the serum of the immature bird on treatment with œstrogen3. It can be shown by zone electrophoresis on filter paper that two new major protein fractions appear in the serum on œstrogenization, one of these being specially rich in protein ...

When hens kept for commercial egg production reach the end of their economically viable life span, they are usually transported to a processing plant for conversion into meat products. In this article, we review methods used in Canada and the United States for the catching and removing of these "spent" hens from the layer house and the subsequent ...

Triphenylphosphite neuropathy in hens
Archives of Toxicology, 1995Single doses of triphenyl phosphite (TPP), a triester of trivalent phosphorus, cause ataxia and paralysis in hens. Characteristics of neurotoxicity were described as somewhat different from organophosphate induced delayed polyneuropathy (OPIDP), which is caused by triesters of pentavalent phosphorus.

Egg allergy is one of the most frequent food allergies in infants and young children. The prevalence of egg allergy is estimated to be between 1.8 and 2% in children younger than 5 years of age. The reactions are mainly mediated by IgE and partially by non-IgE or are a mix of both types.

Behavioural Processes, 1993
The study attempted to assess the aversiveness of various sounds by allowing six hens to move to one (or other) end of a chamber to turn a sound off. A number of sounds at varying intensities were used, including intermittent and constant pure tones and a number of taped sounds.

Agents and Actions, 1983
In adult hens diamine oxidase (histaminase) activity was found in gastrointestinal tract (with the highest value in ileum), liver and spleen. Intestinal diamine oxidase is predominantly a particle-bound enzyme. In the intestine oxidation of putrescine leads to delta 1-pyrroline formation, in liver both delta 1-pyrroline and gamma-aminobutyric acid are ...
