Analysis of growth characteristics and carcass composition of selected hybrid combinations of pigs
KOMOSNÝ, Michal
Two hybrid combinations with an almost equal ratio of barrows and gilts (Large White Landrace) (Large White-sire line Pietrain) - experiment 1 and (Large White Landrace) Pietrain - experiment 2 were included to the monitoring (70 head). The rearing of piglets was going on in the experiment 1 from 25 to 60 days of age and in the experiment 2 from 28 to 63 days of age. Higher live weight and average daily gain were achieved in barrows of both hybrid combinations. A lower consumption of feed per 1 kg of gain was found in barrows. Feed consumption per 1 kg of gain was statistically significantly influenced by gender in the experiment 1. In the experiment 1, fattening was going on from 60 days of age and was evaluated up to 130 days of age. The first group was fed with an ad libitum diet (AD), the second group was fed with a moderate restricted diet (MR) and the third group was fed with a strong restricted diet (SD). AD barrows and gilts achieved the highest live weight and average daily gain. The lowest feed consumption per 1 kg of gain and the highest lean meat content were recorded in barrows and gilts of SR. In almost all traits, with the exception of lean meat content, greater differences between groups of feeding methods were recorded in barrows. Live weight and average daily gain were significantly influenced by the feeding methods. Feed consumption per 1 kg gain was significantly influenced by gender. Experiment 2 was going on from 63 days of age and is evaluated up to 133 days of age. The first group was fed with an ad libitum diet (AD), the second group was fed with a restricted diet from 85 kg live weight (R2) and the third group was fed with a restricted diet from 65 kg live weight (R3). Also in the experiment 2, the highest live weight and average daily gain were in AD barrows and gilts and the lowest in R65 groups. The differences between ad libitum or by restricted-fed pigs were not as significant as in the experiment 1. The lowest feed consumption per 1 kg of gain was in barrows R65 and gilts R85. Lean meat content was the highest in AD barrows and R65 gilts. Live weight and average daily gain were significantly influenced by the feeding method and gender. Feed consumption per 1 kg of gain was significantly influenced by the feeding method. The slaughter value traits were converted to an age of 148.9 days in the experiment 1. The highest slaughter weight was in AD barrows and gilts. The lowest average backfat thickness and with a related highest lean meat content (FOM) were in SR barrows and gilts. The highest pH45 was in barrows of both restricted groups and MR gilts. The lowest drip loss was in SR barrows and MR gilts. The highest IMF content was recorded in AD barrows and gilts. Backfat thickness and lean meat content (FOM) were significantly influenced by the feeding method. Lean meat content (FOM) in the AD group and MLLT area in the SR group were significantly influenced by gender. The slaughter value traits were converted to an age of 141.3 days in the experiment 2. The highest slaughter weight was in barrows and AD gilts. The lowest backfat thickness was in R85 barrows and R65 gilts. The highest lean meat content (FOM) was in the R85 groups for both sexes. The highest pH45 was in barrows AD and gilts R85. The lowest drip loss and the highest content of IMF was in barrows and gilts R65. The results of the experiment 1 for the hybrid combination (LW L) (LWSL Pn) showed that it is suitable to use ad libitum feeding for both gilts and barrows, depending on the technological and organizational possibilities of the breeder, to apply a stronger feeding restriction. In terms of costs per 1 kg of gain, it was shown in the experiment 2 for the hybrid ombination (LW L) Pn as the most suitable feed restriction from 85 kg of live weight, when the growth potential of pigs was best utilized with adequate feed conversion. Results of the trials showed excellent growth potential

The monitoring of vitamin D content in the diet of university students
KALETOVÁ, Nikol
The aim of the diploma thesis was to evaluate the level of vitamin D saturation in a selected group of university students at the University of South Bohemia in České Budějovice. The recorded diet method was used for the research. The research group included six men and six women aged 19-26. The research ran from the 10th February to 14th June 2020. Respondents recorded a week-long diet every second week in February, April and June. This captured possible seasonal fluctuations in the diet. Respondents recorded the amount and type of food and meals consumed. In the monitored group of respondents, vitamin D values averaged around 4.86 g per person per day. The values obtained do not correspond to the recommended daily intake of vitamin D, which according to DACH (2018) should be 20 ?g per person per day for men and women of this age category. In the group of women, the average intake of vitamin D was 3.88 g / day and in men the intake was higher, namely 5.85 g / day. The obtained levels agree with the results of other authors. Alimentary intake of vitamin D is usually in the range of 2-4 g / day, which is confirmed by the results of the diploma thesis. The lowest average daily intake was found in women to be 2.81 ?g / day and the maximum value in men on average 11.26 g / day. This value is at the level of 50% of the recommended daily intake. The main statistical finding was to demonstrate a difference in vitamin D intake between the gender. Men took more vitamin D than women. Furthermore, a positive relationship between protein and vitamin D intake was demonstrated. Last but not least, the effect of gender on protein intake was statistically significantly demonstrated. Men received more protein than women. The question dealing with the effect of the season on the intake of vitamin D from the diet has not been significantly statistically proven. In the second part, the energy intake and main nutrients were also determined, which according to the final evaluation were very unbalanced.

Vliv pohlaví na produkční znaky hybridů kachny pekingské
KOSTRŮNKOVÁ, Gabriela
The aim of the master thesis was to compare the performance traits of Pekin duck - three hybrid combinations - Cherry Valley, Orvia and Grimaud that were fed to the age of 44 days. The test was performed by the International Poultry Testing Station in Ústrašice. The methodology was based on the guidelines for the implementation of poultry performance testing. Hybrid Cherry Valley achieved the highest fertility of hatching eggs (96%), weight of hatching eggs (88,1 g), live weight at age of 1, 21, 35 and 44 days (age of 44 days - 3 315 g), average daily weight gain (74,1 g), carcass weight (2 217 g) and weight of the breast muscles with skin (636 g). Hybrid Orvia showed the lowest feed conversion ratio ((2 165 g/1 kg of weight gain) and mortality and the highest weight of leg muscle with skin (551 g). Drakes showed higher live weight, average daily weight gain, weight of the breast and leg muscles with skin and lower weight of abdominal fat .

Digital divides in aspect of gender
Rohlíková, Pavla ; Nečas, Vlastimil (advisor) ; Soukup, Martin (referee)
This diploma thesis Digital gender gap deals with the issue of the digital divide in connection with one of the aspect that can affect it. The thesis outlines the concept of the digital divide as a problem of modern globalized society and presents the basic theories for understanding the issue. The digital divide is related to several social factors that are outlined in this work, but the main focus is on the gender aspect. Even in the modern world, it is not possible to completely close the gap in this context just yet. Thus, the characteristics of the problem in connection with the gender factor are outlined. Today, rather than the problem of the primary digital divide, it is the problem of unequal skills and the way in which information and communication technologies are used in our society is being talked about. After defining the basic concepts and this phenomenon, the work presents several foreign studies to create a comprehensive overview of the issue and also data from the Český statistický úřad are presented. The second part of this work is a methodological part, which was inspired by foreign study from 2014, which monitors the digital literacy of respondents. For my purposes, I chose a quantitative methodological strategy. The work includes a Factor analysis of the questionnaire survey,...

This diploma thesis deals with issues of pupils' behavior and discipline at elementary schools. It consists of a theoretical and practical part. The theoretical part deals with basic concepts and general problems of discipline and inexplicably with available literature. The practical part is focused on the research of the frequency of individual manifestations of disruptive behavior, it is determined whether the lack of discipline is associated with one of the selected characteristics of the pupil, such as the type of school, gender, socio - economic situation of the family and the development of the frequency of individual manifestations of disruptive behavior from the sixth to ninth grade. The aim of the thesis is to find out the extent of undesirable behavior in selected schools. The research method used is the statistical analysis of the data and the collection method is in the form of questionnaire. The result is a summary of the most frequently occurring unruly behavior at second level of the elementary school and its comparison within selected characteristics from the pupilś point of view. Self-evaluation is compared with the evaluation of unruly behavior from the point of view of the class and with the assessment of hypothetical person's suggestion. Key words Discipline, school discipline,...
