Behavioural synchrony (allelomimetic behaviour), and inter-individual distances are aspects of social and anti-predator strategies which may have been affected by domestication. Chickens are known to adjust synchronization and inter-individual distances depending on behaviour. We hypothesized that White Leghorn (WL) chickens would show less synchronized behaviour than the ancestor, the red jung...

The preparation of a series of normal stages of the cliick embryo does not need justification at a time when chick embryos are not only widely used in descriptive and experimental embryology but are proving to be increasingly valuable in medical research, as in work on viruses and cancer. The present series was planned in connection with the preparation of a new edition of Lillie’s Deuelopiiaen...

The purpose of this study was to analyze the effect of auditory enrichment (by means of classical music) or physical enrichment (by means of hanging colored string bunches and barley grains on the floor) on tonic immobility duration, heterophil to lymphocyte ratio, and fluctuating asymmetry (FA) in chicks of several layer breeds. In experiment 1, 192 chicks from 8 Spanish breeds and 1 White Leg...

Newcastle disease (ND) is highly contagious and usually causes severe illness that affects Aves all over the world, including domestic poultry. Depending on virus’s virulence, it can impact nervous, respiratory, digestive systems cause up to 100% mortality. The chIFITM genes are activated in response viral infection. current study was conducted quantify mRNA of vitro ND It also examined its abi...

Human-driven selection during domestication and subsequent breed formation has likely left detectable signatures within the genome of modern chicken. The elucidation of these signatures of selection is of interest from the perspective of evolutionary biology, and for identifying genes relevant to domestication and improvement that ultimately may help to further genetically improve this economic...

The aim of this study was to describe meat quality and carcass characteristics of the Padovana breed of chicken. The Padovana chicken is a historical fancy breed found in the Veneto region of Italy and produces meat that is typical to some local markets. The experiment reported here involved 60 chickens reared in an organic production system where housing was an indoor pen with access to a gras...

Th e aim of this study was to compare the genetic variation of fi ve local chicken breeds reared in Poland. Twenty-seven microsatellite markers were investigated in 138 birds belonging to fi ve breeds: Miniature Cochin (MCO), Gold Italian (GI), Green Legged Partridge (GLP), Silver Italian (SI) and White Leghorn (WL). One hundred eighty fi ve alleles were detected in the overall population, with...

The Cosmopolitan Chicken Project is an artistic undertaking of renowned artist Koen Vanmechelen. In this project, the artist interbreeds domestic chickens from different countries aiming at the creation of a true Cosmopolitan Chicken as a symbol for global diversity. The unifying theme is the chicken and the egg, symbols that link scientific, political, philosophical and ethical issues. The Cos...
