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.

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.

Comparison of different methods of milk-fed calves housing
DUBOVÁ, Dagmar
Calf is the most important animal on the farm. Calf rearing should be given due attention as many problems and ailments in the herd as a whole have their origins in calves. The right choice of technology o f rearing can be crucial to the economy of the entire breed. Quality of calf housing is reflected in the overall level of rearing cattle in this category. It has a significant impact on the overall w ellbeing of animals, zoohygienic conditions and health situation.The aim of this thesis was to compare methods of rearing calves in individual outdoor sheds, where the calves were fed twice daily, with group housing in a spacious calving barn with multip le feeding through a feeding machine. We looked at weight gain, hea lth and welfare of the animals.The thesis was dealt with at a private farm of Václav Duba in Boubín near the town of Horažďovice. The experiment was conducted simultaneously in both systems of calf housing in the time period between May 1 2013 and October 14 2013. Both the observed groups of calves were fed the same amount of milk replacer, only with different frequency of intake. Both groups had the same number of 30 calves (15 heifers and 15 bulls) of Czech pied cattle. After completion of the milk feeding period the average weight of the calves in individual sheds was 107.2 kg and 110.8 kg in the calving barn. The calves which were fed by a feeding machine had an average daily weight gain of 0.787 kg; the calves in individual sheds had lower weight gain of 0.743 kg. The average consumption of milk replacer for calves in the individual sheds was 521.7 litres and for calves in the calving barn it was 516.8 litres. This indicator has been pro ven to have high statistical significance (P 0.001). The a verage daily temperature in the individual sheds was 19.7 °C; in t he calving barn it was 17.9 °C. A diarrheal disease was reported in four animals in the individual sheds, and in six animals in the calving barn. In calves reared in the individual shed mutual sucking of muzzle was found immediately after drinking. In calves fed using a feeding machine there was no sign of unsatisfied sucking reflex.

Noise in the vicinity of farms for rearing calves.
ŠÁMAL, Jiří
The work deals with noise in the vicinity of farms for rearing calves. In this work addresses the size of the noise that affects animals and humans around them. Data collection were two sound level meter, which we recorded the noise. Values are summarized in graphs. From graphs is clear, that there is overturned hygiene standards. This is reason, why there is no need to propose changes.
