Parametry užitkovosti a kvalita vajec u křepelek nosného a masného typu
 Sekaninová, Aneta
The aim of this diploma thesis was determine and verify the quality of eggs and intensity of laying in the meat-type and egg-type in Japanese quails. Further two lines of meat-type quails that were divergently selected on the shape of the growth curve were included in the study. Two lines of egg-type quails, whose were breeded an intensive positive selection of parent populations. Egg weight, albumen weight, weight and color of yolk and shell weight were monitored, also observed the intensity of the laying in experiment. The monitoring period of the laying intensity was about 6 months in meat-type quails and about 8 months in egg-type quails. Experiment was carried out within the framework of breeding in the area of MENDELU. Meat-type quails had an average heavier egg compared to egg-type quails, but the laying of intensity was higher in egg-type quails.

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.
