Most bird species studied thus far have no distinct brown adipose tissue (BAT) or a related type of thermogenic tissue ; however, our recent studies on cold (4- 6°C)-acclimatized chickens suggest that...
Gonadotropin Releasing Hormones and their Receptors in Avian Species
GnRH GnRH receptor reproduction
2009/7/30
In all vertebrates, gonadotropin releasing hormone (GnRH) is a key component of the hypothalamo-pituitary-gonadal axis. In birds, two distinct forms of GnRH (cGnRH-I and cGnRH-II) have been characteri...
Profiles of Virulence-associated Genes of Avian Pathogenic Escherichia coli Isolates from Chickens with Colibacillosis
APEC broilers molecular detection virulence genes
2009/7/29
The colibacillosis caused by avian pathogenic E.coli (APEC) is responsible for a significant loss of productivity and mortality in the poultry industry. The pathogenicity of these bacteria is based on...
