Porovnání výkonnosti potomstva německého ovčáka po domácích a zahraničních plemenících
FEIKOVÁ, Klára
This graduation thesis deals with comparison of performance of progeny of German shepherd the national and foreign stud dogs. The literary overview follows the history and current form of the International Examination Rules, breeding of German shepherds in the Czech Republic and on global level. It describes complete characteristics of a German shepherd, like the physique, body measurements, living demands and then it is engaged in influences affecting the sport performance of dogs, breeding conditions and it follows the most frequent health problems in German shepherds breeding. The core of the thesis includes analyses of performance of gets of national and foreign stud dogs in the position of a father or father's father in selective competitions, Czech Republic Championships IPO and Championships of the Czech Club of German Shepherds (M ČKNO). There were monitored the data on numbers of individuals in specified competitions in monitored periods of the years 2009 2016. More, dogs placed on 1st up to 10th positions at MČR IPO and M ČKNO were assessed from the point of view of fathers and grandfathers. On the basis of detailed monitoring and analysis it was detected that that dogs from foreign stud dogs origin whether in father's or grandfather's positions are more frequently used in sport cynology. There were 58% of participating dogs from foreign stud dogs and only 42% of dogs with fathers of Czech origin participating in selective competitions. It was established that 61% of participating dogs from foreign stud dogs and 39% of dogs with fathers of Czech origin participated in MČR IPO. The stud dogs of dogs participating in ČKNO Championship were of 68 % of foreign origin and 32 % of nationals. In the course of more detailed analysis (assessment of dogs taking up to 10th position in MČR IPO and M ČKNO) it was established that 67,9% respectively 61,25% of the most successful sport dogs have fathers from foreign kennels, while only 32,1% respectively 38,75 % are from stud dogs from Czech kennels. The best stud dogs from abroad were Ellute von der Mohenwiese and Tom van't Leefdaalhof. Jaguar Aritar Bastet and Hoky Va Pe belonged to the best national stud dogs.

Hodnocení přežitelnosti spermií ovčáckých plemen psů
Sobotková, Lenka
Topic of this work was evaluation of spermatozoa of shepherd dog breeds, where we took a closer look on evaluation of dog ejaculate quality from FCI I. group. In this work the basic methods of ejaculate evaluation were mentioned as well as special evaluation methods, with focus on durability tests for needs of fresh semen insemination with use of special solutions. For our purposes were chosen 7 dogs, 5 of them were Czechoslo-vakian shepherd of one owner and 2 dogs were German shepherd breed of the second owner. For the best elimination of environmental influences on results these dogs were masturbated in home environment. As solutions we used UHT milk, dry milk, Androhep, Androstar, stallion solution and distilled water. We used standard mathematical-statistic methods for data evaluation.

Behavioural selection criteria for Czech police puppies to assess their chances of certification.
Hradecká, Lenka ; Bartoš, Luděk (advisor) ; Martin, Martin (referee)
The project based on behavioural tests of 7 week old German Shepherd puppies performed in police kennel in Prackovice nad Labem and Domažlice. The project focused on verification of the usability and improvement of the selection of puppies using behavioural test. We tested the possibility of environmental effect (presence of shooting range near the kennel Domažlice) on the later success of puppies in the behavioural test. The aim of the project was collecting additional data which were use to improve and verify procedure for early selection of puppies. We checked the possibility of habituation breeding females and their puppies to noise, including monitoring of the different environments in the kennels in. It was found that different results are affected by of their mothers. This means that puppies raised by mothers from the police kennel near shooting range are better evaluated later in the disciplines of evaluating response to noise compared with pups from mothers of police kennel without shooting range. Worse response to noise had pups from litters with a higher number of pups.
Reviews summarizing the literature on heritability of behavioural traits in dogs have been published repeatedly over the last four decades. The conclusions of these reviews vary to some extent. We applied meta-analysis and re-evaluated the literature available collecting 47 references dealing with heritability of behavioural traits in domestic dogs. For each study included, data was extracted for individual behavioural traits. Each of these traits was entered into the analysis as a separate unit of measure, giving a total of 1761 measures. We classified the traits measured in each study into five functional categories (Environment, Herding, Hunting, Play, and Psychical characteristic). The metaanalysis has shown low general heritability of the categorised behavioural traits analysed. Thus, the commonly used behaviour tests for many breeds, to determine the dog's eligibility for reproducing, traditionally required by many associations, is not supported by the present results of the meta-analysis.
