Molecular characteristics of avian leukosis viruses isolated from indigenous chicken breeds in Yunnan Province, Southwestern China.

ABSTRACT: Indigenous chicken breeds have a large market share in China due to their superior production traits, including high meat quality and disease resistance. Yunnan Province is recognized as a major source of domestic chickens globally and boasts a diverse array of indigenous chicken resources.
