The main aim of this bachelor work was the analyzing of reproduction of indicators in private breedings. Furthermore, the growth abilities of chinchillas with colour mutations standard, black velvet and milkiness were appraised too. Altogether data were got from 1292 litters of chinchillas wavy color standard mutation from the period 1999 to 2008. Reproduction charakteristics were evaluated in number of born and weaning the youngs, the length of the interim and the size,weaning index of the litter depending on the order of the litter, the year of the monitoring and the membership of the family. The growth abilities of chinchillas colour mutations standard and black velvet were evaluated according to the order of the litters. Data about development of the live weight were made from data of 25 the youngs - standard colour mutation and 23 the youngs - black velvet mutation. Records of weights were taken place in 2009, on the day of the birth of the young and after every week until the young is 49 days. Data were summarized and statistically processed in MS Excel and Statistica Statsoft version 10. The analysis of reproduction characteristics found out on the average 1.82 the youngs born and 1.52 the youngs weaned with the average length of the interim 202.34 days. There were most often two youngs in the litter. The youngs of standard colour mutation evinced bigger average weight than the youngs of colour mutation black velvet.

All potential myrmecochorous plants of the Czech Republic have been detected from different published sources. My study aims to describe common traits of myrmecochorous plants of the Czech flora. One of myrmecochores, lousewort (Pedicularis sylvatica), was chosen for the purpose of finding peaks in seed removal by a Myrmica scabrinodis ant species during a day and year

Common carp (Cyprinus carpio L.) is one of the most important cultivated fish species over the world. In the Czech Republic, the production of carps by pond aquaculture farming has a long tradition and a non-interchangeable appearance in the cultural landscape. The production is mainly executed in semi-intensive systems, were a combination of natural feed with additional feeding of cereals is applied. Mostly all available cereals are used for supplemental feeding. Due to that cereals represent one of the most important economic factors in the business. It is estimated that these cost can be around 30 35% of total costs within the carp farming. A possibility to reduce these costs is to increase the production efficiency of the cereals, using a suitable technological pre-treatment. The chosen technological treatment should be simple, cheap and easy available for the common practice in fishery. This thesis examined technological treatments of cereals. The main management and production data were examined in respective to the economy. Also the possible impact on the environment of different treatmented cereals in pond aquaculture, especially balance of total phosphorus was evaluated as well as the impact of on flesh quality and the textural properties of carp, respectively.

The main aim of this thesis was to analyse growth abilities of hybrids (?Nb x ?Kal) in comparison with original parental population. Further were evaluated reproductive properties of parental breeds of rabbits New Zealand White and Californian and their combination (?Nb x ?Kal). Enter data were gathered in total from 27 litters. Obtained data were summarized and statistically treated in MS Excel programme and STATISTICA version 9. To assess the development of live weight, the rabbits were weighed at 7-day intervals from birth until the end of fattening, it is to the age of 126 days. For the analysis of reproductive abilities was in single females litters observed the number of all born offspring, from that the number of live-born and still-born offspring and the number of weaned offspring. Further, the length of gravidity, the length of season and age at weaning, milkiness and total mortality were observed. The assessment of growth and reproductive abilities was made in dependence on sequence of litter and on the observed calendar year. The results showed higher increases in 60th, 90th and 120th days of age hybrid offspring than a breeds pattern book by paternal population requires. The achievement of high weight gains confirms the suitability of using these hybrids for intensive production of quality dietetic rabbit meat. It was also achieved excellent results in milkiness females in the observed breeding. Its average value was 3965 g, which is comparable with milkiness of broiler breeds in large breedings. Total results confirmed the suitability of using Californian rabbit breeds in a maternal position and the New Zealand White in a paternal position to create commercial hybrids intended for fattening. Their hybrid offspring reach better growth ability than original parental population. Results of this study can be specific recommendation especially for small breeders of meat-type rabbits when choosing a suitable combination of breeds for fattening.
