Data-Genomic selection based on random regression test-day model in dairy cattle with respect to different reference populations

Test-day record of the first lactation: each test-day record covered four traits, including milk yield (MY), fat yield (FY), protein yield (PY), and somatic cell score (SCS).首个泌乳期测定日记录：每份测定日记录涵盖四项性状，分别为产奶量（milk yield, MY）、乳脂产量（fat yield, FY）、乳蛋白产量（protein yield, PY）与体细胞评分（somatic cell score, SCS）。
