Vliv vazného ustájení na parametry mléčné užitkovosti dojnic ve vybraném chovu
Skoupý, Roman
The aim of this work was to find out the influence of bonded housing on the parameters of milk productivity of dairy cows in a selected farm. The work took place in one calendar year 2022 from January to December. Among the monitored parameters were fat content (%), protein (%), lactose (%), amount of milk produced (kg), stage of lactation (days) and order of lactation (n). The samples were obtained from our own breeding and evaluated in the Laboratory of Applied Lactology at the Institute of Animal Breeding and Breeding, Faculty of Agriculture, Mendel University in Brno using the Julie C5 Automatic device. A total of 12 samples from 4 cows of two breeds, namely Holstein and Czech Spotted cattle, were processed. The results show that bonded housing has a significant effect on the milk production of a dairy cow. The fat content is influenced by the method of breeding but also the feeding technique and the health status of dairy cows, when the fat content was very different in individual months. The protein content was influenced by the order of lactation, where the higher the lactation, the lower the protein content. Lactose was not affected by any factor and was constant.

Effect of the housing technology on sow´s reproductive parameters
KUČEROVÁ, Marie
The aim of this bachelor thesis was to write a review focused on the reproductive parameters of sows, the influences affecting them and the description of the housing technologies for sows. Another part of the thesis was to analyze the reproductive parameters of sows bred in the original technology (1,186 litters) and sows bred in a new technology (2, 240 litters). New technology ensures a better animal welfare. Sows housed in the original technology had 0.07 more all born piglets (14.40 resp. 14.33 pieces). In the number of piglets born alive was noted the difference of 0.20 piglet (12.82, resp. 13.02 pcs), in the number of surviving piglets was the difference of 1.36 piglet (10.31, respectively. 11.67 pcs), always in favour for the new technology. Sows housed in the new technology gave birth to 0.27 less stillborn piglets compare to those bred in the original technology (1.58 resp. 1.31 pcs). Differences in the number of surviving piglets and the number of stillborn piglets were confirmed as statistically highly significant.

Impact of selected factors on laying hens and egg quality.
ZDICHYNEC, Martin
In accordance with the specification of the thesis I developed a methodology target program and I watched it four identical halls, which have different technology housed laying hens. In this thesis are analyzed indicators lay in the selected poultry company in the South Bohemia for the impact of housing hens, their nutrition and feeding. In the selected company enterprise on the one hand technology is used enriched cages EUROVENT - EU Big Dutchman and on the one hand technology aviary housing system used LIBRA with the Italian company of SKA.
