Prospects for transgenesis in the chick [PDF]

open access: yes, 2004
Research to develop a useful method for genetic modification of the chick has been on-going since the first demonstrations in the mouse in the 1980s that genetic modification is an invaluable tool for the study of gene function. Manipulation of the chick

Mu-Opioid Receptor is Involved in β-Endorphin-Induced Feeding in the Meat-type Chick

open access: yesThe Journal of Poultry Science, 2008
β-Endorphin is an endogenous ligand for both mu- and delta-opioid receptors (MOR and DOR), and has an important role in feeding behavior in the central nervous system in mammals. The present study was done to elucidate whether central injection of &

p38 Mitogen-activated Protein Kinase Regulates Oscillation of Chick Pineal Circadian Clock [PDF]

open access: yes, 2003
Extracellular signal-regulated kinase (ERK) and p38 are members of the mitogen-activated protein kinase (MAPK) family, and in some cases these kinases serve for closely related cellular functions within a cell. In a wide range of animal clock structures,

Oral Administration of L-Citrulline, but not L-Arginine or L-Ornithine, Acts as a Hypothermic Agent in Chicks

open access: yesThe Journal of Poultry Science, 2015
Some amino acids are important regulators of key metabolic pathways and necessary for several physiological functions. However, little is know about thermoregulatory functions of amino acids.

Effects of a probiotic-fermented herbal blend on the growth performance, intestinal flora and immune function of chicks infected with Salmonella pullorum

open access: yesPoultry Science, 2021
: Salmonella pullorum is a highly pathogenic bacteria in poultry industry. However, antibiotics were restricted in many countries because of the increasing risk of antibiotic resistance, Therefore, an environmental friendly and effective alternative ...

Behavioral Responses of Chicks to a Saccharin-Quinine Mixture

open access: yesThe Journal of Poultry Science, 2018
To date, few reports have been published on the sensitivity of birds to sweet tastes. Therefore, in this study, the behavioral responses of White Leghorn chicks to the sweet taste of saccharin and the bitter taste of quinine were assessed.

Transporter Gene Expression and Transference of Fructose in Broiler Chick Intestine

open access: yesThe Journal of Poultry Science, 2018
Recent studies have suggested that a high-fructose diet leads to the development of metabolic syndrome in mammals. However, relatively little information is available regarding the absorption of fructose in the chicken intestine.

Acoustic mechanisms of a species-based discrimination of the chick-a-dee call in sympatric black-capped (Poecile atricapillus) and mountain chickadees (P. gambeli) [PDF]

open access: yes, 2010
Previous perceptual research with black-capped and mountain chickadees has demonstrated that these species treat each other’s namesake chick-a-dee calls as belonging to separate, open-ended categories.

Serotonergic Neurons in the Chick Brainstem Express Various Serotonin Receptor Subfamily Genes

open access: yesFrontiers in Physiology, 2022
Serotonin (5-hydroxytryptamine, 5-HT) is a phylogenetically conserved modulatory neurotransmitter. In mammals, 5-HT plays an important role in the regulation of many mental states and the processing of emotions in the central nervous system. Serotonergic
