Management chovu ovcí plemene suffolk v malochovu
Buchtová, Nikola
The aim of the bachelor thesis is to describe the management of Suffolk sheep breeding in small-scale farming. The thesis describes all the essentials that are associated with sheep breeding on your own farm. It includes, first of all, the issue of reproduction, but also nutrition. The thesis includes practical results of reproductive indicators that were collected on a selected farm in the town of Šumperk from 2016 to 2022. The results concern the evaluation of reproductive indicators of the monitored breeding in ewes, where different success rates in pregnant stallions were recorded in individual years. Attention is also paid to the evaluation of reproductive indicators of the monitored breeding in rams, where a stagnant situation in the success rate of pregnancy from 2016 to 2020 was found. A slight downward trend was then observed. Subsequently, the reproductive indicators of the breed were evaluated, where the numbers of births, lambs reared and the number of losses were compared. Results vary from year to year.

Factors affecting oetrous cycles in the house mouse (Mus musculus)
Havrdová, Leona ; Stopka, Pavel (advisor) ; Němec, Pavel (referee)
Factors affecting oetrous cycles in the house mouse (Mus musculus) Abstract This bachelor thesis deals with factors which have significant influence on house mouse (Mus musculus) oestrous cycle. Main theme is oestrous cycle modulation caused by male or female chemical signals. Familiar phenomena like Bruce effect, Whitten effect and Lee-Boot effect are described in detail along with newly explored social modulation issues (ovulation trigger, male genotype role etc.). Environmental impact is also included, especially role of Bisphenol A in connection with negative impacts on human reproduction (tested on mice). Key words: oestrus, pheromone, MUP, Mus musculus, vomeronasal organ
