  1. 1. Control and Development of the Autonomic Nervous System in Posthatch Broiler (Gallus gallus domesticus) and Red Junglefowl (Gallus gallus)

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

    Author : Åsa Näsström; [2015]
    Keywords : Adrenegic tone; Autonomic nervous system; Broiler; Cholinergic tone; Heart rate; Red Junglefowl RJF ;

    Abstract : Heart rate is tonically regulated by the two branches of the autonomic nervous system (ANS); parasympathetic activation decreases heart rate while sympathetic activation increases it. Previous studies on the ANS in chickens have focused mainly on embryonic development, but it is largely unknown what happens in the weeks following hatching. READ MORE

  3. 2. Domestication related genotype on ADRA2C - a determinant of fear response in chickens?

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Amir Fallahshahroudi; [2012]
    Keywords : Chicken; Fearfulness; Genetics; Domestication; ADRA2C;

    Abstract : White Leghorn (WL) breed is homozygous for an allele on the α2C-AR gene while the Red Junglefowl (RJF) is mostly heterozygous for that. The gene is also hypermethylated in WL. READ MORE

  4. 3. Effects of domestication on social support in chickens (Gallus gallus)

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Rebecca Katajamaa; [2012]
    Keywords : Social support; White Leghorn; red junglefowl; domestication; social behaviour;

    Abstract : Social support is thought to give animals benefits from social partners, such as improved coping with challenges. The aim of this study was to investigate differences in social support in the red junglefowl (RJF) and a domestic layer strain, the White Leghorn (WL). READ MORE

  5. 4. DNA methylations : A comparison of four genes between Red Junglefowl and White Leghorn

    University essay from Molekylär genetik

    Author : Johan Bélteky; [2011]
    Keywords : High-resolution melting; DNA methylation; White Leghorn; Red Junglefowl; domestication;

    Abstract : Domestication of animals has given rise to a great phenotypic divergence in selected animals and rapidly generated species of animals more accustomed to human contact and social interactions within the species. Previous studies in chickens (Gallus gallus) have managed to find behavioral and adaptive differences between Red Junglefowl (RJF) and White Leghorn (WL), differences inherent to the domestication process.

  6. 5. Effects of a mutation on the TSHR gene on social and fear related behaviours in chickens.

    University essay from Institutionen för fysik, kemi och biologi

    Author : Johanna Axling; [2011]
    Keywords : Dometrication; Thyroid hormone; Chicken; Fearful behaviour; Dominant behaviour; Thyroid stimulating hormone receptor TSHR .;

    Abstract : It has been shown that thyroid hormones are important in development and growth in birds and further that thyrotropin (TSH) signaling regulated photoinduced seasonal reproduction. In addition to controlling the development of certain physiological traits, TSH can affect a wide range of phenotypes related to domestication such as behaviour, growth rate, more frequent reproductive cycle’s, pigmentation and also behaviour.
