Stabling influence on the performance parameters of laying hens
KECLÍKOVÁ, Magda
The aim of the thesis was comparing production parameters of laying hens breeding in different housing systems at a production enterprise, it means in enriched cages and aviary. There is used the laying hybrid ISA Brown for production consumer eggs. The achievement during 13months' cycle shown that in each laying month except 1st laying month the higher hen-day egg production was fond out by hens in enriched cages. The hen-egg production per month was higher in enriched cages too. The higher mortality was demonstrated by hens in aviary during all laying months. Both housing systems reached the highest mortality in the 13th laying month. The hens in aviary had higher feed consumption per egg during all months. Higher daily feed consumption was assigned by the hens in the aviary in the 1st, 2nd and 3rd month and from the 9th to the 13th laying month. In other laying months the hens in enriched cages had higher daily feed consumption. Feed costs formed the highest entry of total costs.

Breeding hens ? launching of fortified cages
HEINDL, Jakub
This bachelor thesis deals with problematic of launch of fortified cages. From 1.1. 2012 new regulation from European Union came into practise. This regulation is valid for all mass breeds within EU and deals with obligation of tranfer from unfortified cages to fortified cage systems. Specified requirements are solved in new regulations of the Council 1999/74/EC. New legislative regulations have many impacts, amoung egg producers and at the same time among final consumers . In theoretical part of the thesis problematic of this field is being examined with focus on explanation of basic terminology. Practical part follows the fulfillment of the target, in terms of impact analysis from the consumer´s and producer´s point of view. Furthermore the market analysis of the recent situation has been processed and moreover nowadays conditions of housing in cages according to the welfare were compared.
