Long-Term and Transgenerational Effects of Stress Experienced during Different Life Phases in Chickens (Gallus gallus)
Stress in animals causes not only immediate reactions, but may affect their biology for long periods, even across generations. Particular interest has been paid to perinatal stress, but also adolescence has been shown to be a sensitive period in mammals. So far, no systematic study has been performed of the relative importance of stress encountered during different life phases. In this study, g...
متن کاملThe effects of early stress on life-time strategies of behaviour and coping in chickens (Gallus gallus)
Stress is often an important consideration for animal welfare. A number of factors can contribute to stress in domestic animals, most notably thoseused in food production. We investigated the effects and heritability of stress in domestic chickens (Gallus gallus). Using a spatial learningparadigm, we tested an early social isolation-stressed group and their offspring against unstressed ...
متن کاملchHDAC11 mRNA Expression During Prenatal and Postnatal Chicken (Gallus gallus) Brain Development
Background: Histone deacetylation plays an essential role in transcriptional regulation of cell cycle progression and other evolutionary processes. Several results confirm the importance of the latest found HDAC11 gene to deacetylate histone core in neurons and their supportive cells in developing the vertebrate Central Nervous System (CNS). Objectives: This study investigates the HDAC11 pote...
متن کاملDomestication and ontogeny effects on the stress response in young chickens (Gallus gallus)
Domestication is thought to increase stress tolerance. The connection between stressor exposure, glucocorticoids and behavioural responses has been studied in adults, where domestication effects are evident. Early stress exposure may induce detrimental effects both in short-and long term. Previous research has reported a lack of glucocorticoid response in newly hatched chickens (Gallus gallus),...
متن کاملMolecular phylogeny of some avian species using Cytochrome b gene sequence analysis
Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...
