Zhodnocení reprodukce a vlastní užitkovosti v nukleovém chovu přeštického černostrakatého plemene
JANEČKOVÁ, Blanka
The main objective of the thesis was to evaluate the reproductive utility and the achieved parameters of its own utility of the nucleus herd reared on the farm in Mladotice. The detected results have been compared with the average of the Prestice black-pied breed population. The attention has been paid to the lines of the boar representation. The number of all born piglets, the alive born ones and the weaned ones has been regarded during reproductive qualities assessment. The average daily growth, the muscle proportion and the back fat height have been evaluated while assessing the own utility. The origin of the Prestice black-pied breed with the following regeneration process with the assistance of Mirgorod, Liven, Cornwall, Berkshire, Wessex and German saddleback breeds, which contributed to the resistance of the Prestice black-pied breed, has been described in the literature review. The improvement process followed after the regeneration, especially by using Pietrain, Hampshire and Landrase breeds. The characteristics of the Prestice breed with reference to its tilted ear and typical black-pied coloring without body parts defining have been elaborated. Furthermore, the utility, the population development in the last five years and the preservation of the breed as a genetic resource have been described there. In the thesis the own utility of the Prestice black-pied breed of the nucleus herd reared on the Mladotice farm has been evaluated that does not reach breeding goal. The Akoga line is the best line considering its own utility. The reproductive utility has been evaluated as excellent. The Wiskont line has the best results. Statistically significant differences have been found among the lines considering both its own utility and reproduction.

Evaluated the utility of prestice black-pied pig
JANEČKOVÁ, Blanka
Objective of this work was evaluate the reproductive utility qualities of the sows of prestice black-pied pig of basic herd, respectively nucleus herd reared at the farm Mladotice and these indicators compare with other breeds in the Czech Republic. The main endpoints were the number of all born piglets, number of alive born piglets, number of weaned piglets and milk production in twenty days of age piglets. Special attention was dedicate lines of representation boar. The paper describes the characteristics of prestice black-pied breed with reference on its typical breed character, such as tilted ear and typical black-pied coloring without defining body parts for white and black. The study also introduces emergence of breed, prestice black-pied regeneration process where were used breeds of mirgorodské, livenské, wessex saddleback and essex. Regeneration process led to establishing lines Aron, Vojta, Střelák, Filip, Ríša, Flak, Silar and Titus. After the regeneration was performed improvement, above all pietrain breed. The work describes prestice black-pied breed´s utility. At reproductive utility is paid attention to great maternal qualities, at productive it is quality of the muscle. The study give an account of genetic resources conservation with summarising numerical status of prestice black-pied breed in the Czech Republic since 2002 to 2014.
