“Drying off” lactating dairy cows is the process of successfully and efficiently closing down the lactation process in readiness for the dry period – a time of rest and recuperation for not only the cow but also her hard-working milk secretory cells in her udder.
In this, part one of a two-part series about drying off dairy cows, we explore the basics of just why the cow and her udder deserve a well-earned break over the dry period. What “good” might look like for the ideal dry-off process is defined, and the role (or not) for gradual step down from twice-a-day to once-a-day milking before the dry off process.
The second part of this two-part series (Episode 31) covers the role for nutrition in the dry off process for lactating cows.
