Vliv kvality mleziva na růst a zdravotní stav telat
RAJTROVÁ, Aneta
The thesis summarizes the importance of the quality of colostrum, its composition and impact on the growth and state of health of calves. Colostrum includes important substances necessary for the health of a calf. The value of overall protein in which the amount of immunoglobulins is reflected is a key indicator. It is important for the health of the calf that it receives sufficient amount of quality colostrum in time, gaining immunoglobulins necessary for the first weeks of life. Significant aspects include the quality of colostrum that we provide a calf with, the amount of colostrum consumed, technology, consistency and personnel responsibility, which reflect retrospectively during the inspection of colostrum nutrition of calves that can be carried out by several methods mentioned further. These aspects influence the state of health of calves, growth and many more indicators in the production that follows. In the work, I concentrated on these very aspects, the extent to which they interact as well as on the state of health of calves. The data that I was provided with by Ing. Barbora Šitnerová (principal livestock specialist of Agraspol Předmíř a.s.) was processed into tables and graphs from which statistically important results were learnt.

Effect of some factors on passive immunization level in calves
ŘEŽÁBKOVÁ, Zuzana
The base for rearing healthy calves is a high level of passive immunity, which protects calves in a challenging period after birth. In examined herd of the Holstein cows was evaluated the influence of selected factors on the level of passive immunization in 57 calves, expressed as total protein content in calf blood serum. The selected factors were: the quality of colostrum, the time of first intake of colostrum after birth, the weight and sex of calves. The proper level of passive immunization was found only in 33 (57, 9%) calves in the studied breed. Insufficient immunization resulted in a high mortality which reached rate of 10% in 2017. The level of the passive immunization was most affected by the quality of colostrum (P < 0, 001) and the time of first drinking after birth (P < 0, 0230). The other observed factors (calf weight and gender) were not statistically significant. Adequate care for the youngest age category is crucial and influences the profitability of the breed.

Vliv kvality kolostra na pasivní imunizaci telat
HÁLOVÁ, Daniela
This bachelor thesis occupies with the impact of quality of colostrum on calf passive immunity. Colostral immunity represents important milestone in calf life which decides about immunity of organism in early phases of its life. The first part deals with the nutrition of calves, mainly focused to the colostral period. Diseases of digestive and respiratory tract which occur often in calves from birth to weaning and cause huge economic losses are characterized in the second part. Chapters in the third part describe methodes of evaluation of quality of colostrum and level of passive immunity in calves. The closing part describes results of study and recommendations related to the farm where this study was realized.

The evaluation of passive immunization level in meat calves in selected breeding
KRUPKA, Martin
The aim of the thesis was to evaluate the influence of selected factors on the level of passive immunization of calves (expressed in total protein, g/l in blood serum) in selected beef cattle breeding. In the monitored period 2014-2016, a total of 205 samples of calf serum were evaluated. The selected factors were: the length of dry period and parity, colostrum quality, the time of first intake of colostrum after birth, the weight and sex of the calf. An adequate level of passive immunity was found in 90.2% of calves. This result was also reflected in low calf mortality rates in monitored years: 1.16% (2014), 1.15% (2015) and 1.23% (2016). At the level of passive immunization, the time of the first colostrum intake (P < 0,001), parity (P = 0,0002), colostrum quality (P = 0,0061) and the length of dry period (P = 0,0008) were the most important factors. The other evaluated factors (sex and birth weight of calves) were not statistically significant. Colostrum period management is essential for the rearing of healthy calves and profitability of breeding.

The influence of the quality of the colostrum on the growth and health of calves
BERÁNKOVÁ, Anna
Bachelor thesis presents a summary of the importance of colostrum, its composition and compared to mature milk. Colostrum contains important proteins that ensure the health status of the calf. Total protein in colostrum contains important life immunoglobulins, which are involved in immunity calves. For quality connection and future health of calves, you need timely connection quality colostrum and calf submit a corresponding amount. Another important stage in the life of the calf, contributing to good growth and health, the feed technique, which is described in the relevant literature review section. There is also characterized by the meaning and role of colostral immunoglobulin. The methodology applied by methods of measuring the quality of colostrum and measuring total protein in blood serum from calves. In my own research were processed by the information provided by the company VHD Hradiště. Here, the work was focused on the maternal calves and influences the quality of the colostrum to calves and further quantities of immunoglobulins absorbed into the bloodstream after connecting colostrum. Selected influences on the quality of colostrum, calves health and their weight are processed into tables and graphs. The results were no statistically significant differences.

Immunologic Characteristics of Cord Blood in Children with Increased Risk of Allergy Development Preventive Use of Probiotics
Hrdý, Jiří ; Prokešová, Ludmila (advisor) ; Tlaskalová - Hogenová, Helena (referee) ; Ulčová-Gallová, Zdeňka (referee)
Allergy is one of the most common diseases. Identification of early prognostic markers pointing to an increased risk of allergy development is therefore of increasing importance. Cord blood represents an easily attainable clinical material for searching for prognostic markers signalizing future allergy development. Proportions of Th1 cytokines, Th2 cytokines and regulatory cytokines were tested in cord blood of children of allergic mothers (children in relatively high risk of allergy development) in comparison with cord blood of children of healthy mothers (low risk children). Also the activities of lymphocytes, dendritic cells (DC) and regulatory cells (Tregs) were compared in children of healthy and allergic mothers. The generally increased activity of both in vitro stimulated and non-stimulated mononuclear cord blood leukocytes was proved in children of allergic mothers in comparison with low risk children. The increased activity of DC of high risk children was detectable only after polyclonal stimulation. Significantly less pronounced functional properties of cord blood Tregs were found in children of allergic mothers when compared with children of healthy mothers. The increased reactivity of lymphocytes and DC together with the decreased activity of Tregs can support an easier...

The use and effectiveness of colostrum in cosmetics
Bartoňová, Klára ; Vítová, Eva (referee) ; Němcová, Andrea (advisor)
This thesis deals with efficiency of colostrum contained in cosmetics. The aim of study was to determine whether the colostrum contained in cosmetic preparations have any influence on the state of human skin. The theoretical part is a literary review and it deals with defining the basic concepts and phenomena, especially the colostrum, its composition and properties. There is also discussed the raw materials used for real samples preparation and efficiency evaluated on these samples. There are also described the methods used to evaluate cosmetic products. The practical part is focused on evaluating the influence of hydratation of prepared cosmetic products. The skin hydratation and transepidermal water loss was measured by MPA 5. Consumer tests are attached to this part. Chemical stability of these cosmetics is assessed in a special chapter.

Assessment of diarrheal problems by calves on selected dairy cattle farm.
POLÁČKOVÁ, Eva
The aim of this thesis was to evaluate the prevalence of diarrheal diseases in calves depending on the level of postnatal care of newborns on the selective dairy cattle farm. A total of 299 calving was evaluated on the farm in the period 2013 - 2015. The total mortality of calves was less than 7 %, in which mortality due to diarrheal diseases represented less than 3 %. The colostrum quality was assessed as excellent in 74%. Passive immunization, determined as the total protein content in the blood of calves, was performed in 72 % of the calves well. 60 % of calving happened in ideal hygienic conditions and diarrhea was found in 25 % of them. In contrast, diarrheal diseases were found in 65 % of calving in poor hygienic conditions.
