How to Maximize Income By Managing Days Dry

Most dairy producers are aware that an optimum calving interval is 365 days. This is a normal lactation length of 305 days with a dry period of 60 days. This interval is often looked at as a goal to strive toward rather than a goal that must be reached to maximize income from the sale of milk.

Looking at your herd's average number of days dry is a good indicator of how well your breeding management program is working. Average days dry in excess of 50 to 60 can be attributed to inadequate nutrition, herd health or reproductive problems. If days dry are significantly over 60 days, then a complete analysis of your herd's overall management system may be in order.
