Primary focus of the dissertation is comparison of loudspeaker and headphone reproduction and its influence on the mix balance of classical music recordings. A listening test, which represents an essential part of the thesis, was performed on a test group of sound engineers who prepared mixes of selected recordings using both loudspea-kers and headphones. An analysis of the resulting mixes was performed to find out if any systematic changes could be detected between headphone and loudspeaker mixes. The results disclosed a systematic change in preference of reverberation. Individual approaches of the sound engineers are documented by an extensive graphical section of the thesis. Level of stability of the individual models has been examined using repeated testing on selected participants. Selected headphone and loudspeaker mixes have been further evaluated by a listening group in a second listening test. Differences between the mixes were judged using both loudspeakers and headphones. Answers of the participants were analysed to see if there was an increased preference of headphone mixes when judged using headphones and vice versa. The results didn't show significant preference changes based on type of reproduction. The selected mixes weren't found to be "more optimal" when listened to on their respective reproduction device, nor could they be identified based on the subjective preference test. A special part is devoted to evaluation of an internet-based survey featuring a statistical documentation of loudspeaker and headphone usage in todays music recording industry. Special look has been taken at the group of respondents who indicated classical music as primary music genre of their profession. Another theoretical part of the thesis covers the artistic and technical approach of sound engineers to classical music sound image creation, including commonly used technical resources and stylization methods.

Thesis is focused on assessing the reproduction levels of rabbits in middle-sized extensive holdings. For statistical analysis were used breeds Dwarf Teddy (unrecognized breed), Hermelin, Netherland Dwarf and Dwarf Lop. Factors influencing the litter count, fertilization, gestation length, count of rabbits born and reared and male-to-female ratio of young rabbits. Highly significant values were reported for variance in born and reared counts for Hermelin and Netherland Dwarf breeds, while after categorizing into quality groups was concluded that higher-weight and lower-exterior-quality doe reach statistically highly-significant differences in born-and-reared youngling count. Furthermore, the used breeding technology and litter order influence on reproductive indexes was evaluated.

Základním faktorem ovlivňující chov prasat je reprodukce a její intenzita. Intenzitu reprodukce lze ovlivnit vnějšími a vnitřními faktory, které zvíře obklopují. Z vnějších faktorů se jedná o roční období, výživu a způsoby ustájení z vnitřních genetické dispozice, zdravotní stav, kondice a v neposlední řadě plemeno prasete. Velká pozornost je v moderních chovech věnována hygieně chovu, chovným podmínkám a kondici zvířat. Hygiena chovu a zdravotní stav zvířat je ukazatelem kvality chovu. Velikost vrhu, četnost vrhu a životnost selat vypovídá o kvalitě výživy, stimulaci říje a inseminaci.

The aim of this theis is to evaluate reproducing and production qualities of sheep (suffolk race)in selected breding. Reproducing indicators were followed on the basis of calculated average values in sterility, death after delivery, pregnancy and fertility in percents. From the production indicators, average weight and fat width of rams and female lambs were followwed within the period of 100 days. The results were transformed into tables and diagrams. In this thesis ascertained information was also cetified by scattering analasis of F test on significance surface.

This thesis focuses on the fertility and fertility results in a monitored breeding herd of Limousin beef cattle. It includes a brief discussion of calf birth weights, their viability, and the time of calving. Taking this information into account, the main objective of this thesis is to present concise and accurate information regarding the age of purebred and crossbred heifers when they are first included in the reproduction process. The thesis also aims to evaluate the pregnancy success rates for insemination, embryo transfer, and natural breeding. Finally, the thesis tracks the calving difficulties experienced by cows and heifers after artificial reproduction methods and natural breeding. The conclusion includes calf birth weight figures and identifies the weight difference between newborn bulls and heifers. The results were evaluated using basic statistical characteristics. The collected data was analyzed according to the breeding method used and taking into account whether a cow or a heifer was involved. The age of purebred heifers during their first breeding is 26.1 months. The age of crossbred heifers included in the reproduction process as embryo recipients was 22.6 months. In the case of natural breeding, the crossbred heifers were first included at the age of 28 months due to the seasonality of the breeding season. The pregnancy success rate for first breeding by insemination is comparable to that for embryo transfer 62% and 63% respectively; in the case of natural breeding, the success rate is 92%. The highest number of easy births was determined for natural breeding (95%), followed by insemination (89%), and embryo transfer (only 61%). The birth weight of heifers was 2 kg less than that of bulls, and thus the number of easy births was higher. The average birth weight in 2014 was 41 kg. The top calving time was between midnight and 4:00 am (30% of the breeding cows).

The objective of the thesis was to analyse the reproductive traits of sows on a particular farm with regard to the method used, as observed during the period of one year. The highest rate of live-born piglets per the first litter (12.4) was reached in nucleus breeding. Regarding the mating method, the highest number of piglets born in the first litter (12.7) was reached through natural mating, followed by intrauterine insemination (12.3) and cervical insemination (11.6). During the one-year period, the rate of successful conception at first service was 83.3 per cent of sows in case of intrauterine insemination, 80.6 per cent of sows in case of natural mating and 79.2 per cent of sows in case of cervical insemination. When calculating the number of all born piglets per 100 inseminations, it was found out that 1 028 piglets were born in case of intrauterine insemination, 1 026 piglets in case of natural mating and only 921 piglets were born in case of cervical insemination, that is 107 (or 105) less. The highest number of born piglets (11.8) was reached in sows serviced when they were 256270 days old, followed by sows serviced when 241255 days old (11.1 piglets). With the gestation length under 114 days, the sows farrowed 1.2 piglets more than when the gestation length was over 115 days. With the weaning-to-conception interval under 5 days, the sows farrowed more (12.4) piglets than with the weaning-to-conception interval lasting over 6 days, which resulted in only 11.9 piglets being born.

In this M. Sc. thesis, the influence of selected commercially available hormonal preparations based on hCG (Pregnyl, Chorulon) and GnRH-a with dopamin inhibitor (Ovopel, Dagin, Ovaprim) and their benefits were studied, compared with homogenate of carp pituitary (CPE), during controlled reproduction of weatherfish (Misgurnus fossilis, Linnaeus, 1758) in artificial conditions on the quality of the produced fry. The goal of this thesis was assess the suitability of individual commercially produced hormonal preparations for controlled reproduction of weatherfish and the possibility to replace with them unstandardized use of homogenate of carp pituitary. It was found that use of various hormonal preparations and dosage may to in some extent affect hatchability and survival rate of larvae (fry), the size of the yolk sac of larvae, and the amount of energy deposited in body tissues of larvae. However, demonstrable difference in studied parameters for the application of different preparations on the different hormonal basis (hCG versus GnRH) was not reported. The highest rate of hatching larvae (93.3 ? 3.8%) was observed in the groups treated with preparation Pregnyl 3000 IU - kg-1. In terms of overall survival of the larvae (from deployment of hatched eggs until the end of the experiment) have proven to be the most effective medication Pregnyl 3000 IU - kg-1 (69.9 ? 12.1 %) and Dagin (60.56 ? 11.71 %). Within the thesis has been demonstrated no relationship between hormonal treatment used and the growth of larvae (in terms of achieved total length of body and dry weight). The amount of energy deposited into the body tissues of larvae (gross calorific value) was comparable in all groups, except Dagin preparation, which was recorded impairment losses. For the best, most effective and commendable for control of reproductive hormone preparation carp pituitary homogenate replacing the terms of the assessed indicators can be seen the preparation based on hCG and that is Pregnyl at a dose of 3000 IU - kg-1.

The impact of fish predation on zooplankton assemblage was studied in the mesocosm experiment. Presented thesis focuses on the effect of size selective fish predation on species diversity, biomass and body sizes of zooplankton and the impact of fish occurrence on zooplankton behaviour with regard to diel horizontal migration. I also studied a change in some life history traits of zooplankton caused by fish with a special focus on keystone species of freshwater ecosystems Daphnia spp.

The thesis titled "Evaluation of reproduction and postpartum behavior of sheep in the little sheep farming," deals with the evaluation of basic reproductive performance of sheep and evaluation of postpartum behavior of ewes and lambs. Were monitored herd sheep breed Zwartbles backyard farm in the little sheep farming Laškov. Results herd reproductive performance reporting for 2012 and 2013 were compared with the results of the sheep breed Zwartbles included in the performance monitoring (PM). In 2013 reached monitored herd better results than herds in PM, while in 2012 the results were worse. Only at fertilization percentage values were observed at herd in both years better than sheep in PM. Herd 6 ewes were monitored at the time of embedding in delivery, including behavior during and after delivery. In the context of post-partum behavior was from these 6 ewes monitored their 11 lambs. U monitored ewes were found shorter gestation period than the average gestation period for sheep and ewes in 67% gave birth at night. Length delivery each lamb was variable, but always having the first lamb was longer. Ewes 73% gave birth lying down and her lambs in only 36% started licking the head and nostrils. The newborn lambs prevailed female lamb (64%) and the average weight of lambs was above average. Values relating to getting up and sucking were average, only lambs after complicated delivery was less active than the other lambs. Lambs more preferred right teat at 73% at the first and second intake.
