Development status As a high-quality local chicken breed in alpine regions, Tibetan chicken has been included in the “National Variety Resources Protection List” as early as 2000. However, Tibetan chicken as a chicken species with little artificial selection, its low performance is the most important adverse factor affecting the development of the Tibetan chicken industry. In order to improve the production performance of other places, the measures taken are to introduce high-yield laying hens or meat-and-egg chickens to carry out hybridization improvement on Tibetan chickens. Although this has improved the production performance of Tibetan chickens, it has inevitably caused such a result: the disappearance of purebred Tibetan chickens.
