Abstract excerpt

Langya chickens, a Chinese indigenous breed, exhibit rich genetic resources but relatively low egg production performance. To investigate the genetic basis of egg production traits, we performed low-depth genome resequencing of 1,183 Langya hens and evaluated six phenotypic traits, including age at first egg (AFE), egg number at different laying stages-EN1 (from first egg to 26 weeks), EN2 (27-36 weeks), EN3...
