Abstract

Across species, a similar suite of traits tends to develop in response to domestication, including modifications in behavior. Reduced fear and increased stress tolerance were central in early domestication, and many domestication-related behaviors may have developed as traits correlated to reduced...

Abstract

Many traits associated with domestication are suggested to have developed as correlated responses to reduced fear of humans. Tameness may have reduced the stress of living in human proximity and improved welfare in captivity. We selected Red Junglefowl (ancestors of all domestic chickens) for four...

Abstract

Chickens homozygous for the Dominant white or wild-type allele of PMEL17 were subjected to a broad phenotyping in order to detect consistent differences between genotypes. To exclude feather pecking, the chickens were individually housed without physical contact, from the day of hatching, and...

Abstract

Domestication is an evolutionary process in which animals become adapted to a life in close proximity to humans. There are typically specific selection pressures associated with this, including living in larger social groups than their wild ancestors. We hypothesized that the genotype at a major...

Abstract

Although social behaviour is a major factor affecting the coping of poultry in production environments little is known about how it has been affected by intensive selection processes in fowl. We attempted to clarify selection effects on overall repertoire and occurrence of different social...
