ch were mainly found in the B-A1-E, B-A1-C, and B-I-B haplotypes, respectively. We observed changes in the frequency of certain variants over time in several breeds, such as an increase in the frequency of variants A of β-LG, I of β-CN, and B of κ-CN. With these results, we update and complete frequency data that were first estimated 30 to 50 yr ago, and, for the first time in these breeds, we assess the effect of selection on milk protein variants.This study addresses how the serological status of bovine leukemia virus (
