Domestication has caused a range of similar phenotypic changes across taxa, relating to physiology, morphology and behaviour. It has been suggested that this recurring domesticated phenotype may be a result of correlated responses to a central trait, namely increased tameness. We selected Red Junglefowl, the ancestors of domesticated chickens, during five generations for reduced fear of humans....

BACKGROUND Early traumatic experiences are thought to be causal factors in the development of trauma-related dissociative experiences, including depersonalization and derealization. The rubber hand illusion (RHI), a well-known paradigm that measures multi-sensorial integration of a rubber hand into one's own body representation, has been used to investigate alterations in the experience of body...

The behaviour, welfare, and tibia characteristics of fast- slow-growing chickens were evaluated in free-range intensive production systems. A total 720 birds three strains subjected to these systems after 21 days rearing under the same environment. Each treatment was replicated six times with 20 each replicate. Data collected for welfare aspects, including feather condition, footpad, hock joint...

This study aimed to assess the acute toxicity in rats of heated and un heatedbutylated hydroxytoluene (BHT). Sunflower oil dissolved BHT, at 98±2ºC by a water bath. The animals were divided into five groups. control group dosage orally with sunflower oil, first treated 250 mg/kg second heated, BHT third 500 fourth BHT. All groups received oral treatment. results showed substantial reduction mot...

BACKGROUND Tonic Immobility is a temporary state of motor inhibition in situations involving extreme fear. The first scale developed for its assessment was the 10-item Tonic Immobility Scale (TIS). However, there are still few studies on its structural (dimensional) validity. The objective of this study was to reassess the factor structure of the TIS applied to representative samples exposed to...

Abstract Keel bone fracture (KBF) of laying hens has become one the important welfare problems for health and production performance. The present study aimed to assess fear responses in native breed Lindian chickens commercial Hyline Brown with without KBF at late period. At their 56-week-age, a total 76 80 selected from furnished cages were housed individually battery cages. divided into norma...
