Under stressful condition, reproductive function is impaired due to the activation of various
components of the hypothalamic–pituitaryadrenal (HPA) axis, which can suppress the …

Gonadotropin-inhibitory hormone (GnIH) is a hypothalamic neuropeptide that was isolated
from the brains of Japanese quail in 2000, which inhibited luteinizing hormone release from …

Increased average air temperatures and more frequent and prolonged periods of high
ambient temperature (HT) associated with global warming will increasingly affect worldwide …

Reproductive function is suppressed by several types of stress. Hypothalamic kisspeptin,
which is a product of the Kiss1 gene, and GnIH/RFRP have pivotal roles in the regulation of …

Abstract Gonadotropin-inhibitory hormone (GnIH), a 12 amino acid peptide, is expressed in
the avian brain and inhibits luteinizing hormone secretion. Additionally, exogenous injection …

Food abundance is closely associated with reproductive readiness in vertebrates. Food
scarcity can activate the hypothalamo–pituitary–adrenal axis, decrease sex steroid …

High ambient temperatures (HT) reduce food intake and body weight in young chickens, and
HT can cause increased expression of hypothalamic neuropeptides. The mechanisms by …

With global warming, heat stress is becoming a pressing concern worldwide. In chickens,
heat stress reduces food intake and growth, and increases body temperature and stress …

Recently we demonstrated that L-citrulline (L-Cit) causes hypothermia in chicks. However,
the question of how L-Cit mediates hypothermia remained elusive. Thus, the objective of this …

Heat stress causes an increase in body temperature and reduced food intake in chickens.
Several neuropeptides and amino acids play a vital role in the regulation of food intake …
