Former CowCalf5 users:

As many of you know, I left the University over 5 years ago, and Dr. Rupp retired in 2010, and passed in 2020. It was a great pleasure to work with the many ranchers and veterinarians that used our CowCalf5 program for over 35 years. The University has no intentions of continuing developing and supporting CowCalf5, so it is being discontinued. The CowCalf5 program should continue to work on your computer, as it has in the past, but the mobile android/iOS CowCalf app will not be able to email data or sync with CowCalf5. There will be no further support or development of either. I encourage anyone still using CowCalf5 to look at migrating to a different platform that will be supported and have continued development.

There are other cow records programs on the market, with many having demo versions available to try. I have not personally tried any of these, but I have worked with Jimmy Curtis (CattleMax Product Manager and former CowCalf5 user) to help them develop a method to migrate historic CowCalf5 data to their platform.
I have enjoyed helping all of you over the year with your cattle records.
