  1. 1Internal animals = animals associated with only internal information; External sires: sires associated with external information; 2EVALI = BLUP evaluation based on internal pedigree and data; EVALBE = Bayesian evaluation using external EBV and PEV associated with the 50 external sires used in the internal population; EVALBJ = Bayesian evaluation using EBV and PEV obtained from the joint evaluation and associated with the 50 external sires; EVALBJ-I = Bayesian evaluation using EBV and PEV obtained from the joint and from internal evaluations and associated with the 50 external sires to avoid double-counting among internal and joint information; r2 = rank correlations between EBV estimated by EVALJ and by EVALI, EVALBE, EVALBJ or EVALBJ-I;3MSE = mean squared errors expressed as a percentage of the average internal MSE between a joint evaluation and EVALI, EVALBE, EVALBJ or EVALBJ-I; 4a = regression coefficient and R2 = coefficient of determination of the regression of EBV estimated by the joint evaluation on EBV estimated by EVALI, EVALBE, EVALBJ or EVALBJ-I; 5REtot = total amount of record equivalents free of contributions due to relationships among external animals.
