The elite chickens carrying favorable SNPs identified in this study can be selected in breeding programs to improve economic benefits for poultry farmers.
Abstract
Simple Summary Body weight is a critical indicator to evaluate the growth performance of chickens at all production stages and is a core parameter for early breeding selection. Given that the NCAPG-LCORL locus has been widely reported to regulate animal body weight and skeletal muscle development, this gene region was selected as the research candidate. Based on genotyping-by-sequencing (GBS) data from an F2 resource population, we screened SNPs within the NCAPG-LCORL locus. After linkage disequilibrium (LD) analysis, association analyses were performed between tag SNPs/non-tag SNPs and 12 economic traits. Furthermore, we explored the regulatory effects of NCAPG and LCORL on the proliferation and differentiation of chicken skeletal muscle satellite cells (SMSCs) at the cellular level. The elite chickens carrying favorable SNPs identified in this study can be selected in breeding programs to improve economic benefits for poultry farmers.
The Charolais sheep is a world‐renowned breed of meat sheep, known for its large frame, heavy muscling, and rapid growth. A novel breed, the Chao Mu meat sheep, has been developed by utilizing the Charolais sheep as the paternal line. This advancement has significantly contributed to the genetic enhancement and breedin...

A coordinated host genome–gut microbiota–metabolite network underlying early growth variation in goats is defined to provide a mechanistic foundation for precision breeding and targeted nutritional strategies in goat production systems.
The study was conducted to identify the genotypes of single-nucleotide polymorphisms (SNPs) in the GHRL, GAST, and SCTR genes for early performance assessment in Smena 9 poultry. The study was performed on 170 CM5/CM7 roosters and 750 final-hybrid CM5679 broiler chickens with individual feed intake monitoring at ages 3...
