Hello Tabby (maybe Catherine),

I am wondering about matured dates for a few females that show up with 
MANY MANY conversion errors. In the newest version of Babase there are 
no dates for KUP ,LUL, and PRE. Have the matured by dates for females 
all been incorporated yet? Should these three individuals have a matured 
by date? These three show up in mounts, consorts, and ejaculations but 
have no matured date in biograph.

Thanks,
Leah
