gamma-aminobutyric acid egg production egg quality
2015/11/26
Hy-line brown commercial layers (32 weeks old) were used to investigate the effects of GABA
(gamma-aminobutyric acid) derived from E. coli strains on productivity, egg quality, and blood profile. In...
Opioid-induced hypophagia is mediated by 5-HT2c receptors in neonatal layer-type chicken
opioidergic 5-HTergic system food intake layer-type chicks
2015/10/9
Opioidergic and serotonergic (5-HTergic) systems have crucial role in central regulation of food intake. This study was designed to investigate the role of the opioidergic system and the interaction w...
A two-layer canopy model with thermal inertia for an improved snowpack energy balance below needleleaf forest (model SNOWPACK, version 3.2.1, revision 741)
