A genomic predictor for age at sexual maturity for mammalian species [PDF]

Evolutionary Applications
Age at sexual maturity is a key life history trait that can be used to predict population growth rates and develop life history models. In many wild animal species, the age at sexual maturity is not accurately quantified.

Dissection of the gene regulatory network underlying sexual maturity divergence in Jining Bairi chickens through integrated RNA-seq and WGCNA analysis [PDF]

Poultry Science
Sexual maturity is a pivotal reproductive trait in laying hens because it is directly related to egg production. The age at first egg is a definitive indicator of sexual maturity attainment in laying hens. Most Chinese indigenous chicken breeds exhibit a

Identification of biomarkers associated with sexual maturity in laying hens based on metabolomics and gut microbiology [PDF]

Poultry Science
Sexual maturation is an important trait in poultry production. The initiation mechanism of sexual maturity is significant for breeding high-yield laying hens. Plasma metabolomics and gut microbiology were used to identify biomarkers of sexual maturity in
