• Resumen

  • This review discusses the use of lineal procedures to evaluate cattle in multibreed populations for traits of economic importance. First, a multibreed mixed linear model was presented in detail, and all their terms were defined. Then, computational algorithms to solve multibreed mixed model equations and to estimate additive and nonadditive variance and covariance components were discussed, and the types of multibreed predictions obtained in these analyses were explained. Finally, applications of multibreed procedures to experimental and field datasets were presented, and implementations of national multibreed systems in the United States were discussed.
