Pregnancy Rate Detection - Heifers

The Pregnancy Rate Detection - Heifers report provides data to track heifers' pregnancy rates according to 21-day estrus cycles. Heifers eligible for analysis and inclusion in the report must be at least 13-months old. Use this insight to determine your success in identifying heat and pregnancy eligible cows and processing them effectively. The report can generate data according to user-defined periods, allowing you to compare performance data over extended periods.
