AI Technical Summary
Existing technologies make it difficult to accurately identify the growth and development traits of yellow-feathered broilers in the early stages, resulting in difficulties in increasing chicken yield and feed conversion rate, high production costs, and low breeding efficiency.
Through genome-wide association analysis and cis-eQTL co-localization, SNP molecular markers associated with body weight at 87 days and 113 days and mid-cycle metabolic weight were identified. Combined with whole-genome resequencing data, genetic variations that significantly affect growth and development traits were screened out, providing molecular markers and their selection methods for early selection and breeding of faster-growing broiler breeds.
This technology enables precise identification of genetic loci in the early stages, increases body weight at different ages, meets consumer demand, reduces production costs, and significantly improves the economic benefits and breeding progress of the broiler industry.
