Využití plemene přeštické černostrakaté v hybridizačním programu prasat
Jeřábek, Vojtěch
The aim of the thesis was to describe the use of Přeštice Black Pied breed in the hybridization program. In the literature review is described the birth and development of the breed, as well as its breeding characteristics. Successive processed information about reproduction and production properties, along with an overview of the achieved performance. Another part is the theoretical description of the hybridization program, distribution, structure and also its practical principles. The final part describes the possibilities of breed Pc in the hybridization program. Given the possibility to include purebred and hybrid boars for breeding. Also described a project that addressed the suitability Pc breed to alternative fattening, describes and explains the results with the possibility of using this breed in the system. At the end of the final section describes genetic resources, among which include Pc breed. It also works indicates which direction should proceed breeding Přeštice Pied breed to 2020.

Vliv hybridní kombinace prasat na kvalitu masa
Ondrůšková, Gabriela
The aim of work was to learn about breeds of pigs used in the hybridization program and define influences acting on their final meat quality. The first part discusses the current state of the pig industry in the Czech Republic and characterizes the individual breeds and their lines used in breeding. Furthermore, the work focuses on meat quality indicators associated with sensory and technological properties and nutritional value of meat. The main part describes factors affecting the final quality of the meat, which is divided into internal, external and technological factors. In the last section provides current values of scientific research on the issue of the quality of pork.

Hodnocení genetického pokroku ve šlechtění prasat plemene pietrain
Doupal, Jaroslav
The aim of this thesis was to evaluate the genetic progress in the breeding of pietrain pigs. The evaluation was conducted on the indicators of reproduction and production traits. Data for monitoring progress were derived from the hybridization program of the Czech Republic for the period 2000 -- 2014. For the evaluation were used 2865 births, 2368 values for gilts and 2387 for young boars. The results show that the level of reproduction has increased from 8,70 to 9,30 live born piglets (+6.98%). Growth ability is worse, the decrease in the average daily gain in gilts is from 606 g to 557 g (--8.08%) and the decrease in young boars is from 647 g to 626 g (--3.25%). During the reporting period the conformation breed increased for gilts from 62.1 % to 65.2 % lean meat (+3.32%) and for young boars from 63.8 % to 66.2 % lean meat (+3.76%). According to the breeding goals for 2020 both of the monitoring indicators did not reach the desired values. In breeding of this breed will be needed to improve especially the growth ability.
