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.

Vliv kvality kolostra na pasivní imunitu telat
ŠEFRNOVÁ, Šárka
This bachelor thesis occupies with the impact of quality of colostrum on calf passive immunity. The passive imunity decides about immunity of organism in early phases of its life. The bachelor thesis has two parts - literature reserch and own work, which is results of study and recommendations related to the farm where this study was realized. Own work describe methodes of evaluation of quality of colostrum and level of passive immunity in calves. The expert part of this work deals by the characteristics of the Holstein breed, prenatal care for the mother, calf nutrition, diseases of digestive and respiratory tract, characteristics of colostrum and immunity.

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...

Odchov telat s použitím různých dávek mléka
Paulíčková, Michaela
The aim of the thesis was to compare the effect of feeding calves with different doses of milk on their health condition, weight and weight increment, consistency of faeces, blood parameters and the effect of plant nutrition. The experiment was carried out with 2 groups of calves (n = 30), the first group (experimental) was fed with 6 liters of milk per day and the second group (control) with 10 liters of milk per day. Calves were fed twice a day and had drinking water and starter all the time. Calves were fed with colostrum within 2 hours of delivery and were on colostrum nutrition for 3 days, the fourth day they were included in the experiment, they were weighed and converted to the milk feed mixture. The second weighing was done at the end of the experiment at the age of 38 days. The third weighing was done at the age of 155 days, when the calves were on plant nutrition. The average birth weight of all calves was 33,5 kg. The final weight was statistically significantly lower in the experimental group, the average final weight was 57.8 kg and in the control group 65.9 kg. The mean total weight increase in the experimental group was 26.4 kg and in the control group 30.3 kg. The intake of starter was statistically significantly higher in the experimental group. The experimental group had a better evaluation of faeces consistency. On the second blood collection, the experimental group had a blood ?-glutamyltransferase level over the reference range, and it was 0,62 µkat/l and the difference between the experimental and control group was statistically demonstrated. Statistically significant was the higher albumin level in the control group at the second blood collection. The results of the experiment clearly do not show a better or worse effect of feeding different doses of milk during the milk diet, higher doses of milk provided higher weight increase during the milk diet, which means higher economic costs.

Vliv kolostra na imunitní systém telete
Pilková, Kateřina
The importance of cow colostrum in the immune system of the newborn calf is well known. Insufficient or incorrect feeding of colostrum significantly participates in the morbidity and mortality of calves. That‘s why this bachelor thesis focuses on immunity and colostrum receiving. The bovine placenta is impermeable to antibodies and therefore the calf is born without developed defence. Passive immunity is obtained through colostrum from the mother. Colostrum after the birth versus normal milk contains more immunoglobulins, proteins, fats and vitamins, which nourish and protect the body of the calf. The intestinal wall is permeable to immunoglobulins only during the first 24 hours after the birth, so it is important that the calf is fed by the colostrum as fast as possible and in as large quantity as possible.

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.
