Özet

The objective of this study was to evaluate the effects of body condition score (BCS) and daily milk yield (DMY) on reproductive characteristics of dairy cows. A total of 1249 records of Czech Fleckvieh cows raised at a private farm in Prague were enrolled. Dairy cows were grouped according to BCS (1 = <= 3.75, 2 = 4-4.25 and 3 = >= 4.50) and DMY groups (<20kg, 20-30 kg and >30kg). Number of inseminations per pregnancy (NI), days open (DO), service period (SP) and ovarian cyst (OC) cases were evaluated as reproduction characteristics. While the group with BCS = 4.50 presented higher DO, the group with BCS <= 3.75 had lower OC cases when compared with other BCS groups. The group with DMY<20 kg had higher DO but lower OC cases than other DMY groups. Significant correlations were estimated between SP and NI (r = 0.843) or DO (r = 0.256), and between OC and DO (r = 0.546). The results revealed the effects of BCS and DMY on DO and OC and associations of reproduction traits each other. Therefore, close tracking production and reproduction data is suggested as a major process to prevent fertility problems and to obtain high productivity in dairy cows.
