Evaluation of reproductive parameters at a farm specializing in breeding of Czech Fleckvieh dairy cows
Original language description
The aim of this study was to evaluate the level of selected reproductive parameters at a farm specializing in breeding Czech Fleckvieh dairy cows. The study was carried out at the farm AZOS, s. r. o. Zakřany. Reproductive parameters were assessed in 291 cows in the years 2017, 2018 and 2019. The longest calving interval was 400 days for cows on the 4th lactation and there was not a statistically conclusive (p>0.05) difference. The shortest calving interval of 378 days was found in cows at 2nd lactation and there was not a statistically conclusive (p>0.05) difference. Cows had more difficult calvings when they had twins than when they had one offspring. It was also established that the length of gestation was shorter in twin pregnancies. There was a statistically conclusive (pLESS-THAN OR EQUAL TO0.01) difference in gestation length for cows with a single offspring, where the length of gestation was 285 days, and cows with twins, which were pregnant for 279 days.
