Article Synopsis
- Feed costs are crucial in cattle production, making up about 75% of variable expenses, so optimizing feed efficiency is important.
- The study analyzed the effects of traditional corn and alternative by-product diets on 14 traits related to feed efficiency and methane emissions in 52 Nellore bulls, finding that the alternative diet had better outcomes in weight gain and lower methane emissions.
- Genetic analysis revealed 487, 484, and 499 differentially expressed genes in the liver, muscle, and rumen respectively, showing that specific genes and their connections relate to the improved traits observed with the alternative diet.
Copy number variations (CNV) are an important source of genetic variation. CNV has been increasingly studied and frequently associated with diseases and productive traits in livestock animals. However, CNV-based genome-wide association studies (GWAS) in Santa Inês sheep, one of the principal sheep breeds in Brazil, have not yet been reported.

We identified CNVs along the chicken genome and analyzed their association with performance traits. Genome-wide CNVs were inferred from Affymetrix® high density SNP-chip data for a broiler population.
