Název v původním jazyce

Evaluation of Holstein cows originated from embryo transfer

Popis výsledku v původním jazyce

Embryotransfer (ET) is used in reproduction worldwide. This thesis deals with the evaluation of milk yield at Holstein cows that were from ET. This evaluation was done by performed flushes and transferring the offspring, born and included in the breeding during the years 2015 and 2016. All data for the experiment evaluation was obtained from an agricultural cooperative, which has three farms located in the region Pardubice. For statistical analysis of the data, we used multifactor analysis of variance. In 2015, 14 donor cows were flushed. A total of 212 embryos were obtained from which 113 embryos could be used. In 2016, 19 donor cows were flushed and 241 embryos were obtained, but only 113 embryos met the criteria. In the experiment, we evaluated the performance of daughters from embryo transfer and compared their performance with their peers (not from ET) born in the same stable and the same years. Performance evaluation was obtained during the first and second lactation. From the results, where the production performance is compared, it is evident that there was no statistically significant different production difference between dairy cows from ET and their peers.
