The dairy cattle recording results are among the basic information sources for breeders and breeding organizations, which is related to the improvement of breeding and breed quality. The aim of the work was to document the activity and working conditions of breeders at dairy cattle milk recording, resulting in possible optimization of some procedures in the process of control of dairy cow performance used by breeding company Natural, spol. s r.o. Another part of the thesis contains a draft of a curing plan for selected cattle breeding in order to improve its utility level. The work was followed by eight breeds, which were visited with breeding techniques four times in different seasonal conditions. In the breeding control, the breeding difference between breeds of Czech pheasant and Holstein was observed in two breeds. The preparation plan for the selected enterprise was prepared on the basis of performance monitoring documents. The monitoring showed that the technologies of milking have an impact on the time consuming of the dairy cattle milk recording process, while the positive impact on the time requirements after the transition to the electronic processing of the performance check documentation was confirmed. Other influences on the work of the worker are mentioned in the thesis. In the milk dairy inspection, an average milk yield of 2.6 ? 0.5 l / min was observed in fourteen Czech breed cows and an average fertility rate of 2.4 ? 0.5 l / min in seventeen hounds of the Holstein breed. The average rejuvenation was 13.7?3,3 l for the Czech breed and 17.5?2,1 l for the Holstein breed. By compiling the curing plan there was documented the purpose and the practice of its preparation by the breeding company, including the structure of the dairy cattle milk recording data used. At the end of the thesis, based on the findings from the dairy cattle milk recording, practical recommendations are given. |
