Parametry užitkovosti u nosných hybridů ISA Brown a Bovans Brown
 Forman, Jakub
The thesis focuses on the utility parameters of final hybrids of carrier type ISA Brown and Bovans Brown from the company of Hendrix Genetics. The experiment of thesis has been carried out in clearly defined condition of breeding in period 2016 and 2017, in system of enriched cages on the farm in Drahanovice. The assessment of utility properties of hybrids ISA and BOVANS has been realized in two consecutive runs. In both cases the same hybrid was settled with the same technology, climate and stable conditions. ISA in 2017 had the best results in intensity of laying eggs, conversion of feed per one egg and conversion of feed per one kilogram of egg mass and in number of non-standard eggs. The highest weight of the eggs have been identified for BOVANS hybrid in 2016. Highest strength of the shell had hybrid of BOVANS Brown.

The adjustment of the feed ration for laying hens in order to improve the strength and the hardness of eggshells
 HEINDL, Jakub
This major thesis expands the issue of the bachelor thesis "The issue of raising laying hens considering on introduction of enriched cages" and adds new knowledge relating to the topic feed rations and their influence on the final production. The theoretical part of the thesis analyses the basic theoretical concepts cohering with this topic, focused on creating a comprehensive overview of the structure and quality of the eggs, the basic ingredients in the feed rations, qualitative parameters of grapes as the modified additive provided by us and last but not least there is processed the recent overview of the current state of large-scale farmers in the Czech republic. The practical part of the thesis aims to test the effect of the proposed feed with an additive in the form of the crushed grape seeds, on the strength of the eggshell, by homogeneous samples of the breeds through from us proposed measuring instrument. Subsequently, a statistical evaluation of measured results is realized. In conclusion, the consideration is extended to the economic evaluation of costs and profits in case of the implementation of the suggested feed ration into practice in order to quantify the difference compared to the commonly used feed ration.
