Abstract

Fluctuations in daily milk yield (DMY) could be used as an indicator of the health and resilience of dairy cows. We evaluated the natural logarithm of DMY variance (LnVar) in 2,468 Holstein cows distributed on 9 farms. The data were collected between October 2022 and January 2024. Cows were required to have records for at least 20 successive days with the first day in milk (DIM)
