Parametry užitkovosti u nosných hybridů ISA Brown a Bovans Brown

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
