AbstractIdentifying the genes responsible for quantitative traits remains a major challenge. We previously found a major QTL on chromosome 4 affecting several innate fear behavioral traits obtained by an open-field test in an F2Gallus gallus22212NPY5

Testosterone (T) is known to induce aggressive behavior, particularly in male animals. However, our recent results showed that a certain kind of aggressive behavior is T-independent; moreover, the role of T in chicken territorial and isolation-induce

Testosterone (T) is known to induce aggressive behavior, mainly in male animals. Subcutaneous implantation of T-filled silastic tubes, rather than intramuscular injection of T, is generally recommended for long-term treatment using exogenous T. Howev

Chicken agonistic behavior, a type of social behavior related to threatening and fighting, is among the most serious problems in the poultry industry. However, due to luck of effective models for investigating the brain mechanisms of the behavior, no

The Kurokashiwa breed of native Japanese chickens is primarily reared in Shimane and Yamaguchi Prefectures, Japan. To reveal the genetic diversity and differentiation among the Kurokashiwa populations in both prefectures, 29 microsatellites were anal

Activation of the right hemispheric neurotransmitter systems is related to negative emotion and stress in mammals, but this relationship is not fully known in birds. The effect of the presence of sawdust litter on behavior and brain monoamine lateral

It is known that thermal conditioning at an early age results in improved heat tolerance, and reduces mortality when re-exposed to heat in later life in chickens. However, the mechanism of thermal conditioning is not fully understood. The objective o

The objective of the present study was to evaluate the temperament of a native Japanese chicken breed (Tosa-Jidori) using the tonic immobility test for the detection of fearfulness. Each chick (2, 5, 10 or 15-day old) was placed on its back on a tabl

It is important to quantify and estimate stressful stimulation because stress appears to limit productivity and welfare in poultry. The purpose of this study is to investigate the effect of acute isolation stress (5, 10 or 30min) on the levels of blo
