Revista Mexicana de Ciencias Pecuarias. This study aimed to evaluate the impact of including foreign information of Holstein sires on their genetic evaluation for the following traits: milk, fat, and protein production in kilograms. This was achieved by comparing breeding values BV and reliabilities Rgrouping of sires by number of daughters, ordering of sires, and the genetic superiority expected per yearwith different scenarios determined by the selection intensity of sires used in the national genetic evaluation MEX-GEthose incorporated into the international genetic evaluation with daughters in Mexico I-GEand the international genetic evaluation with or without daughters in Mexico MACE-GE.

It also allowed to observe important differences in the BV and R between evaluations, generating an opportunity to improve the Mexican Holstein population. Therefore, it is recommended continuing participating in the Interbull program and consider using the internationally validated information in the selection process of dairy cattle and their components. These actions can significantly contribute to the increase of the productive genetic progress in Mexico.

Different strategies are applied depending on the complexity of the target trait in the breeding germplasm: 1 molecular assisted selection MAS for screening and introgression of valuable alleles for oligogenic traits, for increasing selection intensity and reducing population size for field trials; 2 genome-wide association intensith GWAS for traits with unknow genetic architecture in our germplasm; and 3 mixed models integrating pedigree, genomic, and weather data for prediction complex traits under favorable and unfavorable environments for increasing selection accuracy. With respect to models that explain gene action such as: breeding value and selection, progeny difference, production ability, if we were to define "best" we would simply choose those individuals with the best breeding values.
