  20. Evaluation of reproduction Performance (Fertility index) Calving fert.inse. Dry off calving 0 4 85 309 365 Cholest. Gestation period 280 d. Lactation period 305 d. Dry P.56 d Calving interval 365d.

  21. Fertility index 1. Calving Interval = no. of days (mos.) which elapse between successive calving dates 2. Days Open = no. of days from calving to date of conception 3. Days to First Observed Heat = no. days from calving to first observed heat 4. First Service Conception Rate (%) = % of cows that became pregnant after only one insemination 5. Overall Conception Rate (all cows) = # cows confirmed pregnant x 100 total # svc. for all cows

  22. FollowingFertility index 6. Services/Conception (all cows) = Total # svc. for all cows # cows confirmed pregnant 7. Services/Conception (pregnant cows) = Total # svc. for preg. cows # cows confirmed pregnant 8. 60 or 90-Day Non-Return Rate - used by A.I. organizations to evaluate bulls - cows bred by A.I. technician not presented for second breeding within 60 or 90 day period

  23. Thanks for your attention With my best wishes to all … Prof.Dr. Shehata
