### Expected Calf (EXPCALF)

The EXPCALF option allows you to set the gender of the expected calf (or calves) for a PREG event. This helps your dairy manager decide if a cow needs to be watched more closely for assistance in birth. It can also be used to determine which calf belongs to a cow when she calves in a pen.

The EXPCALF option is automatically available when adding a PREG event in MyDC. DC Unlimited subscribers can configure this option by first adding the EXPCALF item and then setting their PREG event to prompt for it in DC305 DairyComp 305 - VAS Dairy Management Software. [Contact Us](docId:7o2aXqFEMH6N88D1S0-WN) if you need help setting this option in DC305 DairyComp 305 - VAS Dairy Management Software.
