Šrubařová, Markéta
The thesis deals with the natural mating of cattle, excluding the market production, with focus on the time period of using a breeding bull and the reasons for their removal from the breeding. The study includes the description of genitalia both male and female, and also the breeding cycle of cows and the ejaculate of bulls. Further on, the study looks into the process of natural breeding, its rules, advantages and disadvantages, and the dates of spring and winter calving. Shortly described is the selection of breeding bulls, their inclusion to the breeding, the time period of their use, the most common reasons for their removal and the options that enable the elimination of those reasons. In conclu-sion, I introduce a real business, which deals with the breeding of cows without market production of milk. The way of breeding is described, and also the factual replacement of bulls in this business, including reasons for their exclusion from breeding.
