In this study, daily milk yields by period in Korean cattle were
analyzed with an animal model. The milk yields were actually measured at sequential intervals from 1 to 4 months after calving: daily
milk yields from delivery to 1 month (DMY1), from 1 to 2 months (DMY2), from 2 to 3 months (DMY3), and from 3 to 4 months
(DMY4)
