Possibilities of the usage of nonconventional methods and dietary supplements in prevention and in health provision of calves.
ZÁBRANSKÝ, Luboš
It is important to take care of calves and their health for good results in beef-raising. The aim of the work was to evaluate the effect of dietary supplements Lactovita and Biopolym on the frequency of diarrhoea occurrence in calves in the first stages of the period after weaning for milk nutrition. The experiment was conducted in farmers' cooperation Staré Hobzí, where Holstein Cattle are bred. Two groups of calves were made ? control and experimental group. In an experimental group dietary supplements to support active immunity were served according to the guideline. In case of diarrhoea occurrence the calves from experimental group were cured in the same way as the calves from control group. The occurrence of disorders during the period of experiment, method and length of treatment were recorded. Recorded data were summarised and statistically evaluated. The calves were examined from 29th February to 20th December. The results proved positive effect of dietary supplements Lactovita and Biopolym, but these results were statistifically insignificant. It is assumed that in case of studying bigger groups the proof of statistical significance will be more probable.

Dynamics of selected hematological and biochemical parameters in blood plasma of calves in relation to environmental conditions.
BENDA, Michal
The aim of my thesis is to evaluated the dynamics of selected hematological and biochemical parameters in blood plasma of calves reared in different environmental conditions. Totally were collected 120 blood samples of calves in age of 1 to 124 days. The animals came from three different breeds with different ways of rearing. The total blood parameters tested in all observed groups were in the normal range. Dynamics of selected hematological and biochemical parameters in blood plasma of calves in all groups were relatively similar. It is clear that the calves, while preserving the basic animal hygiene conditions of livestock, can cope with the effects of different technologies of rearing and environmental conditions.

Noise mapping in livestock buildings for cattle.
MATĚJŮ, Aleš
The content of this work is to describe the structural characteristics of the objects and characteristics of production technologies. The main objective is to measure noise levels in selected buildings on their land borders. Measurements were stables for breeding heifers and calves. Furthermore, to ensure data from these measurements and their evaluation.

The health problems of calves
BENDOVÁ, Pavlína
The bachelor work is focused on the health problems of calves. The first part describes influences that affect the health condition of calves, in this part are included influences of breeding care, nourishment and stabling. The second part of my thesis is focused on the most serious health problems in calves - reduced viability, respiratory and diarrhoea syndrom.

Prevalence of gastrointestinal parasites in calves reared indors and in hutches.
MOTTLOVÁ, Markéta
On two farms in a two-year period (spring 2005,autumn 2005, spring 2006, autumn 2006) calves faecal samples from the rectum or from the floor were obtained for parasitologic examination. A total of 560 samples from 209 calves were examined using the floatation method in Sheather's sugar solution. In positive samples the presence of Giardia intestinalis cysts, Cryptosporidium parvum, C. andersoni and Eimeria spp. oocysts was found. The infection by C. parvum was the highest from the 1st to the 3rd week and the infection by C. andersoni was the highest from the 7th to the 8th week of the calves age. In both breedings Coccidia Eimeria spp. was the most diagnosed, followed by G. intestinalis. With calves bred in stables by two a higher probability of parasitic infection was detected (46,9 %) compared to breeding of calves in outer individual boxes (17,6). The excrements of the calves were mainly of pasty or even of mushy consistence and the prevalence of the parasites was in most cases diagnosed in single infections.

Possibilities of the application of supplemental and nonconventional methods in prevention and health care in calves
RAABOVÁ, Marcela
Diarrhoeas in calves pose one of the most serious risks of calf management and cause economic losses. This is the reason why the objective of this paper was to evaluate in operation conditions the effect of selected dietary supplements on the frequency of diarrhoea occurrence in calves in the first stages of the period after weaning for milk nutrition. An agricultural enterprise where the workers were willing to cooperate and provide the biological material was selected: ZEFA Volary. In 2005 {--} 2008 calves were examined from 3 to 6 weeks of age on average. After filling the facility, the calves were divided into a control and experimental group. Blood and faeces samples were taken in selected calves of both groups and subsequently they were evaluated. The calves were treated with dietary supplements and their effect on the frequency of diarrhoeas was subsequently evaluated on the basis of the results of blood examination and recorded data (diarrhoea occurrence, diarrhoea duration, length of treatment, method and length of treatment, date of filling the facility and date of calf load-out, weight at the time of filling and load-out). The results were summarised and evaluated by a statistical programme (STATISTICA 7.0.). No statistically significant difference was proved between the particular calves of the control and experimental group. Based on our observations the effects of the treatment with dietary supplements on the frequency of diarrhoea occurrence in calves were not satisfactory in the first stages of the period after weaning for milk nutrition. But it is to state that some tendencies to reach a higher average weight gain were observed in calves of the experimental group in applied dietary supplements even though these results were statistically insignificant.
