The objective of this work was to determine, through the genetic trend, the genetic progress of Charolais herds raised in the Rio Grande do Sul State, and the results utilized in programs of genetic improvement for this breed. The data were collected by PROMEBO (Beef Breeding Program) and the analyses were performed at the Animal Breeding Laboratory of the Animal Science Department of the Universidade Federal de Santa Maria. It was estimated the heritabilities (h²) and the breeding values (BV) […]
