Özet

In this study, 3.814 lactation records of 1.705 Holstein cows from 196 dairy herds of Kayseri Dairy Breeding Association members were evaluated for age at first calving (AFC), calving interval (CI) and number of insemination per conception (NIPC) and financial losses due to deviation from target levels of these parameters were calculated. In the study, average AFC, CI and NIPC were calculated as 821 days, 403 days and 1.8 semens and deviations from target level were determined as 91 days, 38 days and 0.1 semens respectively. In general, average financial losses due to 1 day delay of AFC and CI determined as 15.6 TL/cow (10.4 US$/cow) and 11.3 TL/day (7.5 US$/cow). Consequently, total financial losses due to deviations from target levels for AFC, CI and NIPC were calculated as 3.345.092 TL (2.230.061 US$).
