Vliv ročního období a pořadí laktace na kvalitu mleziva holštýnských krav ve vybraném podniku
Slechanová, Marie
The topic of the bachelor's thesis was to monitor the influence of the season and the order of lactation on the quality of colostrum of Holstein cows. The bachelor thesis is divided into several parts. In the literary research, the work deals with the characteristics, meaning and composition of colostrum. The theoretical part describes the effects on the quality of colostrum or colostrum preservation. In the practical part is characterized, the company that provided the data and samples for this work. Colostrum from dairy cows in the 1st to 3rd and higher lactations during the seasons was evaluated. Density, the amount of lactose in colostrum, and the percentage of fat, protein, and lactose were measured from the evaluation indicators. The results show that the quality of colostrum increases with increasing lactation. Based on the obtained results, it is not proven that the influence of the season has a major influence on the quality of colostrum. The measured values of the indicators were higher or lower on the monitored farm in accordance with the professional literature.

Infekční a neinfekční příčiny průjmů telat v období mléčné výživy
MAŇÁKOVÁ, Lucie
Diarrheal diseases are one of the most common diseases of calves. The aim of the bachelor's thesis was to evaluate the incidence and causes of (infectious and non-infectious) diarrheal diseases in calves during the dairy feeding period in selected breeding of dairy cattle. From January to December 2022, a total of 276 cases of di-arrhea were evaluated, of which 38% were infectious. Cryptosporidium parvum was determined to be the most common cause of infectious diarrhea using a rapid stable test. Bacterial causes of diarrhea were not diagnosed. The cause of non-infectious diarrheal diseases was deficiencies in colostral nutrition of calves, e.g., late feeding of calves after birth. Management of colostral nutrition in the farm will require cor-rective measures.

Výživa telat v období do odstavu
Sladký, David
Nowadays, the topic of calf nutrition in the weaning period is increasingly discussed. The theoretical part of the bachelor thesis describes the period of colostrum, milk and starter nutrition and weaning of calves. Furthermore, an overview of the feeds used in calves during the lactation period is presented, focusing on colostrum, milk replacers, starter feeds and drinking water. In the practical part, the results of a trial of feeding dairy compound feeds from two different producers are described. 20 calves were included in the trial and divided into two groups and after the lactation period, ten of them were fed with Multimilk Vital from VVS Verměřovice and the other group with Telfid Extra from FIDES AGRO, s. All calves were monitored for weight, health, consumption of starter mixture and gains were calculated and an economic evaluation of the cost of rearing calves was carried out. No statistically significant differences were found in live weight of calves, daily gains or consumption of starter mixture throughout the experiment. At one stage of rearing, a higher incidence of diarrhoea was found in calves fed Telfid Extra. Although the final evaluation of the increments showed almost identical results, after recalculation of the economic aspect, Telfid Extra with a cost of 47.57 CZK per kg of increment was more economical than the Multimilk Vital mixture, where the cost per kg of increment in the feed used was calculated at 58.02 CZK.

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.

Vztahy mezi kvalitou mleziva, růstem a zdravotním stavem telat
ŠLEGLOVÁ, Lucie
This bachelor thesis deals with the issue of calf rearing, especially in the period of colostrum and dairy nutrition. As the basis of successful cattle breeding is the breeding of calves, emphasis must be placed on their timely connection with quality colostrum. Colostrum is the first secretion of the mammary gland immediately after calving. It contains important components, especially immunoglobulins, which play an important role in the nutrition of calves, provide passive immunity of calves after birth, health and vital functions in the first ectopic period of the calf cubs. Another important aspect for successful and healthy rearing of calves is, for example, the technology of housing calves or their subsequent nutrition in individual rearing periods, which are also described in the thesis.

Kontrola úrovně imunitní vybavenosti telat
ŠIMKOVÁ, Romana
This thesis deals with the evaluation of calves colostral immunity on a chosen dairy farm. The theoretical part is focused on the passive imunity, its function, transfer and the possibilities of its control. The next part is aimed on the factors influencing this process and on the consequences of its low level. During the study an amount of serum total proteins in calves was observed as an indicator of their passive immunity. In total, 541 blood samples were analysed via optical refractometer. The observation of several factors, such as time between birth and first feeding and use of drencher, was also included. The quality of first-fed colostrum was checked in 78 calves. Collected data were analysed statistically.

Využití probiotických krmných aditiv ve výživě telat
POLÍVKOVÁ, Denisa
The aim of this study was a brief elaboration of a literature review containing the morphology of the digestive system of calves, the issue of methods of their breeding and feeding, probiotics, prebiotics and phytobotics. The following study aims to confirm the positive effect of probiotic feed additives containing the probiotic strain Lactobacillus Sporogenes on calves. A total of 80 calves were included in the project, divided in half into two groups, control and experimental. Both groups were weighed three times, within two hours after birth and then according to the individuality of the individuals at shifts of an average of 56 and 100 days of age. During breeding, in addition to weight, the general state of health, the frequency of diarrheal diseases. From the evaluation of the collected data, it can be stated that the feeding of probiotic additives containing the Lactobacillus Sporogenes strain has a significant effect not only on the health status but also on the weight gain of calves.

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...
