Genome-wide scan highlights the role of candidate genes on phenotypic plasticity for age at first calving in Nellore heifers
Gene set enrichment analyses identified important biological functions related to growth, hormone levels affecting female fertility, physiological processes involved in female pregnancy, gamete generation, ovulation cycle, and age at puberty that support complex interactions between the gonadotropic axes and sexual precocity in Nellore heifers.
Multitrait meta-analysis identified genomic regions associated with sexual precocity in tropical beef cattle.

A meta-analysis study for traits related to sexual precocity in tropical beef cattle aiming to identify important genomic regions affecting these traits consistent with the postulation that reproductive traits are complex polygenic phenotypes.
Heritability and genotype‐environment interactions for growth curve parameters in meat‐type quail fed different threonine:lysine ratios from hatching to 21 d of age
Increase in threonine:lysine ratios promoted higher heritability estimates for these variables in the LF1 genetic group compared to LF2, which indicates that the additive genetic variation was modified due to the environmental variation influenced by the evaluated amino acid ratios, with differences between both genetic groups.
Genotype×dietary (methionine+cystine):Lysine ratio interaction for body weight of meat-type quails using reaction norm models

Genetic variance and heritability estimates were affected by both (Met + Cys):Lys ratio and strain, and it was observed that a G × E interaction was present, with changes in the breeding value ranking.

It is demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake.
Genome-wide association study identified genomic regions and putative candidate genes affecting meat color traits in Nellore cattle.
Genomic reaction norm models exploiting genotype × environment interaction on sexual precocity indicator traits in Nellore cattle.
The results suggest that the inclusion of genomic information combined with the pedigree to assess the G×E interaction leads to more accurate variance components and genetic parameter estimates.
Genetic evaluation of bodyweight, scrotal circumference, and visual appraisal scores in Bos indicus cattle
The genetic values were decreasing over the years for scrotal circumference, body structure, finishing precocity, muscling, and sheath and navel in Guzerat cattle, indicating higher response to selection for BW traits is expected for those with moderate to high heritabilities.

RRM using B-spline functions with four residual variance classes and segments were the best fit for genetic evaluation of growth traits in meat-type quail, and should be considered in genetic Evaluation of breeding programs.
