Vyhodnocení vlivu rodičů na velikost plodu v době porodu

Hrazdirová, Vladěna January 2017 (has links)
The diploma thesis entitled "Evaluation of the influence of parents on the size of a foetus at the time of birth" focuses on evaluating the maternal and paternal relationship to the size of a calf of the Friesian breed in the agricultural enterprise VOS Zemědělců, a.s. Velké Opatovice. The research part focused on measuring the dimensions of a mother (height at the withers, width of tubers costae, width of tubers sacrale, width of tubers ischiadicum), on the lactation order, date of insemination, date of calving and the course of birth. In calves, the dimensions of the width of the head, length of the head, birth weight and sex were observed. Year-long measurements were followed by statistical processing and evaluation of the data based on the results obtained from the measurements of individual cows, heifers and calves during birth. The diploma thesis analyses a database of the number of bulls and heifers for the reference period for which the birth weight and the course of birth were assessed. Furthermore, it assesses the influence of the lactation order of breeding cows on the size of offspring. The breeding cows were divided by the lactation order which is in accordance with their age. Another indicator monitored was the duration of gravidity and its relation to the size of the calf. The breeding cows were divided into 3 groups with various duration of gravidity. Twelve bulls with 312 offspring were included in a more detailed analysis. The relationship of a breeding bull in relation to the duration of gravidity, the size of offspring and the course of birth was assessed. The evaluated results are given at the end of this thesis.

Analýza plodnosti prasnic ve vybraném chovu

KUBALOVÁ, Markéta January 2017 (has links)
The goal of the thesis was to analyze reproductive performance of sows in a selected breeding facility during a three-year period. 602 litters of the breed Czech Large White pig (CLW), 7 632 litters of the Czech Large White the Czech Landrace pig (CL) and 397 litters of the Czech Landrace Czech Large White were included in my observation. The average number of born piglets 15.43 was reached in the basic set of sows, out of which there were 14.25 live-born piglets. The highest number of all born piglets was found in CL CLW (16.25 pcs), followed by CLW (16.03 pcs) and CLW CL (15.34 pcs). The highest number of live-born piglets was found in CLW (14.51 pcs), then with a slight gap followed CL CLW (14.36 pcs) and the lowest number was found in CLW CL (14.22 pcs). The average age at first conception of sows was 235.7 days. Sows, younger than 229 days at first conception gave birth to 0.39 piglets more than sows of the age 230-250 days at first conception (13.42 or 13.03 piglets). The average gestation length was 115.7 days. More piglets were born to sows with gestation length shorter than 115 days, than to sows with gestation length 115 days and more (14.55 or 14.18). The difference of 0.37 piglets was statistically confirmed as highly relevant. The average length of weaning-to-conception interval was 5 days (4.97). More piglets (by 0.44) were born to sows that were serviced within 4 days after weaning, than to sows serviced within 5 and more days (15.03 or 14.58). The difference was confirmed as statistically highly relevant. The average length of farrowing interval was found 152.9 days. Sows were categorized into three groups based on this interval, 132145 days, 146-160 days and 161200 days. Most piglets were born to sows with farrowing interval 146160 days (14.58) and least to sows with farrowing interval 161200 days (14.51).

Analýza úmrtnosti v 50., 60. a 70. letech 20. století v ČR / Analysis of Mortality in the Czech Republic in 1950s, 1960s and 1970s

Jičínský, Jaroslav January 2016 (has links)
Changes in mortality behavior in 1950s-1970s pose a fluctuation of Czech population's mortality trend and still have an impact on current level of life expectancy. The thesis focuses on mortality process in that period from cross-sectional and longitudinal approach and tries to identify how the mortality changes affected age intervals older than 30 and influenced cohorts which were in these age intervals in observed period. In the thesis Arriaga's decomposition method was used for quantification of mortality changes in particular age intervals and their affect on changes of life expectancy. The obtained results show that mostly age groups older than 60 were more sensitive to mortality fluctuations.

Závislost parametrů lokomoce na tělesné výšce dospělé osoby. / Dependance of the gait parameters on a stature of an adult

Maštalková, Petra January 2014 (has links)
Title: Dependance of the gait parameters on a stature of an adult Objectives: The main aim of this study is to find out how the gait parameters depends on a stature of an adult. Another aim of this study is to compare these parameters between group of men and group of women. Methods: This thesis is type of descriptive - association research. In the practical part was used method of comparison for locomotion of people. As an objectification method was chosen 3D kinematic analysis of gait, which was performed using the Qualisys. Results: It was found that the dependence on a stature subject to the step length, pelvic rotation, flexion of a front knee, frequency and walking speed. Linear dependence on a stature is not subject to the the angle between femurs and flexion of a back knee. It was also found that the values of parameters which have the highest rate of variability reach a relatively low angular values. These parameters include the angle of rotation of a pelvis and the angle of flexion of a front knee. Opposite qualities shows the angle between femurs, which reaches the highest value, but clearly has the lowest rate of variability. Keywords: gait, footstep lenght, double support, stature

Vliv rekvalifikačních kurzů na zaměstnatelnost uchazečů o práci

Ciprisová, Lucie January 2015 (has links)
Ciprisová, L. Effect of retraining courses on the employability of job seekers. Diploma thesis. Brno, 2015. This thesis examines whether the passing retraining course has a positive, negative, or neutral effect on the likelihood of finding a new job. I have obtained individual-level data on job seekers registered at the Job Centre in Brno. My approach is based primarily on comparisons of groups of job seekers. The first group (basic group) consists of graduates of the retraining course; the second group (control group) is represented by job seekers who did not pass the course. The data used in this thesis carry information about 486 graduates of the re-training courses and about 245 persons who have not passed the retraining course. After the exclusion of some persons whose profile was not suitable for research, the basic group included 482 people; in two control groups are includ-ed 28 and 47 job seekers. The control group "Z" consists of individuals who would like to pass a retraining course, but their request was rejected by an expert commission. The second control group consists of individuals who refused to attend a retraining course recommended by the Job Centre. Job seekers of these two groups represent extremes of a motivation to find a new job. A comparison of an employment rate and the average length of registration at the Job Centre suggest that a retraining course attendance has a positive effect on the likelihood of finding a new job. These results, however, are significantly influenced by selection of the control group.

Faktory ovlivňující délku pobytu psa v útulku / Factors influencing how long a dog stays in a shelter

PRŮŠOVÁ, Zdenka January 2016 (has links)
There were 1 643 dogs accepted to the dog shelter in Tábor in the years 20082015, wherein the amount of annualy accepted dogs slightly decreased. Dogs, that were returned to the original owner, spent shorter time (median 1 day) in the shelter than dogs, that were left alone and found a new home (median 18 days). The shelter accepted more male than female dogs. Simultaneously, male spent in the shelter longer time than female. Most of the dogs accepted to the shelter were younger than 1 year. The most common colour was black, the majority of dogs had a short and soft hair. Hybrids predominated among accepted dogs, following by German shepherds, Labrador retrievers and Dachshunds (or their hybrids). Dogs with a good character prevailed in the shelter. Data on abandoned dogs were statistically processed. There were found a significant effect of following variables on the length of stay in the shelter - age, height, purebred, temperament, colour, length and type of hair, and also the month of entry into the shelter. With increasing age and size (height) of dog there was demonstrably extended length of dogs stay in the shelter before they were adopted, as well as an aggressive character and dogs accepted in the shelter in October or November. Interestingly, the visually purebred dogs (corresponding to a certain breed standard) looked for a new home longer time than hybrids, provably. On the other hand, dogs with a light-coloured, soft or short hair and dogs accepted in February or April stayed in the shelter shorter time. When advertising the abandoned dogs for adoption, it is necessary to focus primarily on dogs that spend in the shelter longer time on average that means male dogs, large dogs, older dogs, dogs with long, black or rough hair and aggressive or temperamental dogs.

Individuální růst a variabilita časných preimaginálních stádií vodní ploštice bodule obecné (Ilyocoris cimicoides) (Heteroptera: Nepomorpha: Naucoridae) / Individual growth and variability of early development stage of creeping water bug Ilyocoris cimicoides (Heteroptera: Nepomorpha:Naucoridae)

PILAŘOVÁ, Simona January 2014 (has links)
This thesis investigates an influence of environmental variables (temperature and food availability) on development and growth of the first three nymphal stages of Ilyocoris cimicoides Linnaeus, 1758 Individuals were housed individually in experimental cages from eklosis into adulthood. Experiments were carried out in a combination of four different temperatures (17 ?, 19 ?, 22 ? and 25 ? C) and two different modes of food availability (full-fed every day, red-fed every other day) (in eight treatments). The temperature significantly influenced the length of nymphal development. According to our expectation, shortest development was achieved in individuals reared at 25° C. Development period was prolonged by decreasing temperatures. Unpredictably, the nymphs of the 3rd instar had longest development at the lowest temperatures (17 ? C) whereas nymphal development of the 1st and 2nd instars ran faster Both, the lowest- (17 ? C) as well as the highest used temperature (25 ? C) are probably very close to the temperature limits, that corresponds to the limits of postembryonic development. The optimum temperature for development was 22 ? C. Furthermore, it has been found that food availability should also significantly affect growth and development. Surprisingly, less mortality was observed in individuals reared in reduced feeding treatment, except the only case - nymphs reared in low temperature (19 ? C), where higher mortality was found in individuals reared at the same food availability.

SEZÓNNÍ ZMĚNY V KVALITĚ SRSTI KONÍ / THE QUALITATIVE SEASONAL CHANGES OF THE HORSEŚ HAIR

KUBARTOVÁ, Jana January 2007 (has links)
The result of this work was to find out the changes between the summer and the winter horse{\crq}s coat (the length, the thickness and the density). According to the year season, the way of stabling, the sex and the age. The comparison measured five different body parts in winter and in summer. The samples were taken during 24 months from 44 horses every two months. Each sample contained 100 hairs per horse. The samples were taken from the neck. The review of the summer and the winter coat was made of five different body parts {--} the neck, the shoulder blades, the stomach, the saddle and the hip joint. The hair length was measured by the slide rule. The measuring instrument Lanier, which was 500 bigger. The hair number per 1 cm{$^2$} gave the coat thickness.
