System of pupils practice of zootechnical disciplines in agricultural secondary schools
BÚDOVÁ, Alena
The bachelor thesis deals with mapping of the system of practices at secondary agricultural schools. The aim of the thesis is to find out which system of practice at secondary schools of agriculture is the most beneficial for pupils, which best suits them and whether they use their theoretical knowledge in practice. The bachelor thesis consists of a theoretical part, where the forms and goals of the practice are described. The practical part contains research questions, which were realized and evaluated by a quantitative research form of a questionnaire survey among the pupils of SZeŠ Tábor and Secondary School of Veterinary, Mechanical and Horticultural Ceske Budejovice. Conclusions summarize the results of the questionnaire survey and provide personal recommendations for improving practical education.

Charakteristika reprodukčních vlastností hřebců působících v inseminaci
BÚDOVÁ, Alena
One of the requirements for a successful insemination in horse breeding is the selection of quality stallions which produced ejaculate in enough quantities and of good quality. For this purpose were discovered methods of dealing with the evaluation of semen quality. In this dissertation was ejaculate evaluated by using an objective computerized method CASA, system SCA. Monitoring the quality of sperm was performed on 11 breeding stallions involved in artificial insemination fresh sperm in ZH Písek. 53 samples of ejaculate were evaluated. Volume, sperm concentration, total and progressive motility and sperm vitality were monitored. Volume of ejaculate was from 20 to 127.5 ml. Average values of sperm concentration for individual stallions were from 104.18 to 384.4 M/ml. Average values of total motility were moving by interval from 51.23 to 89.54 %. Average progressive motility was move from 12.99 to 47.12 %. At sperm vitality were discovered average results from 35.16 to 71.21 %. The average value of individual stallions was identical to the Decree of the Ministry of Agriculture, which sets minimum requirements for quality indicators for short-term preservation of semen. Also the quality of the semen of stallions was compared by age. The first group was made by stallions to 10 years old and the second group were older stallions. It was found that the younger stallions to 10 years had higher semen volume and greater sperm concentration. Stallions older over 10 years had higher levels of total and progressive motility and sperm vitality. Next ejaculate quality was evaluate by the time interval between samples. Regular taken from stallions is doing better ejaculate quality but the time interval between samples is important. The best values were found in samples with interval between the sampling 4 or more days. The worst quality of sperm was in the samples with the interval between 1-2 days.

Performance tests warm-blood stallions and their evalaution
BÚDOVÁ, Alena
The bachelor´s work deals with the performance tests of warm-blooded stallions and their evaluation. The progress and result of testing performance of warm-blooded stallions in the Czech Republic is analysed in the bachelor's work. The methods of testing stallions are described in the text.The stallions are evaluated under the mare. They can be placed into tested breeding. They have to meet the requirements for granting a pre-selection of stallions into breeding. Then they have to complete a 70day-long test and a performance test successfully. They are evaluated according to competitions for young horses and according to their sports performance. Their offspring are tested. The share of each foreign breeds in the Czech Republic is described in the work. Their testing in neighboring countries in selected breeders associations is described, too. The data were drawn from the records of the Czech warmblood breeders association, Central registry of horses and Czech equestrian federation. It was compiled into tables, graphs and then evaluated in the program Statistica. In the end of the work it was found out, that the number of mares reduces (245 mares less per year in average) and the number of newborn foals is reducing too (average of 139 per year) in the Czech Republic. 354 stallions were placed into tested breedings in the years from 2009 to 2013. From this period only 6 stallions finished the 70-day-long test successfully. The Czech warmblood breed still has the largest number of participants in the pre-selection and the performance test after the 70-day-long test. Every year in the Czech Republic the number of participants and numbers of starts in showjumping and dressage competitions are increasing.
