Influence of feeding TMR Balance on milk yield of dairy cows in a selected breed

In this thesis, it was analysed the current nutrition of cattle especially in calves and cos, because nutrition plays a signifiant role in these categories, leading to the following high milk production. The content of the work is mainly focused on the nutrition of dairy cows and their performance when feeding different feed rations, which were presented to the time in the years 2013/2014 and 2015. Ration differed only in the administered of the product B, when TMR Balance from the time this was shot administered from May 2014. The observation took place on private agricultural farm in Podkrkonoší. The farm was observed a group of dairy cows, mostly Czech pied breed, which had a combined 34 pieces, 4 Holsteins and 30 Czech pied breed. The group of animals arrived in the feed ration years 2013/2014 without granulate TMR Balance B and the same group of dairy cows, then began to submit feed ration with granulate. Statistically are evaluated on the first lactation cows, which were given the first shot immediately after calving. A group of cows which was observed on the first lactation include 11 cows. The work was observed their performance according to the above data form performance tests conducted by the Bohemian- Moravian Association of breeders. On the basis of the results achieved can be stated, that the preparation of TMR Balance B added to the diet increased the productivity of dairy cows on the farm, because the settlement has occurred, the ration supply a sufficient amount of vitamins and minerals needed to produce more high - quality milk and better health of dairy cows. Milk yield of milk is according to achieved and evidence of the results of picking up on the 614,64 kg in 305 days of lactation, on the 802,91 kg in 200 days of lactation, on the 371,59 kg in 100 days of lactation. Demonstrated also increased the performance of the protein for the 28,93 kg
