Possibilities of use of food supplements in prevention and health care calves
PÁNIKOVÁ, Monika
The basis for a successful cattle production is the proper care taking of pregnant cows as well as a sufficient care taking of the new-born calves. During the last years, a big attention has been given to this area because the higher farming quality the higher economic benefits and the lower losses in meat and milk yield will be respectively. For this reason, an influence of different feed supplements (Lactovita, Biopolym, Homeopathics) on haematological and biochemical parameters as well as an effect on weight gain and amounts of microorganisms in new-born calves has been studied. The specific aim of this thesis is to evaluate an influence of these supplements on incidences of diarrhea, microbial activity and to assess its effect on selected haematological and biochemical blood parameters. Three experimental and one control group (ten calves per each) were set up in the chosen company. The experimental groups had a modified feeding ratio between the first and the fourth week of life the calves received either colostrum + 5ml "PVB" homeopathic or colostrum + 5 ml "Biopolym" prebiotics or colostrum + 1 pill of "Lactovita", while the control group received colostrum without supplement. The first day after birth, a blood sample and a microbial smear sample were taken. Second sample collection was carried out in the fourth week of life. The calves were weighed every week. Obtained data were processed graphically and in tables and were statistically evaluated. The influence of mentioned feed additives on weight gain and diarrhea occurrence was evaluated from the obtained results. The most of haematological and biochemical parameters have approximately the same values compared to those found by other authors. There were no significant differences in monitored parameters in the experimental groups compared to the control group. Furthermore, no influence was found on blood parameters. Only in case of zinc a significant difference was found between treated groups and control (p=0,0012). Changes between the treated groups (independently on control) were observed in haematocrit, total protein content, cholesterol, zinc and copper. Non-significant differences between the tested groups and control were found in haemoglobin, erythrocytes, leukocytes, glycaemia, urea, LF, GMT, phosphorus, calcium and magnesium. No impact of tested supplements was found on microbial composition. A positive effect of Lactovita, Biopolym and Homeopathic compared to the control group was found in case of weight gain. The obtained results show some positive trends which should be a subject for further research, where total amount of calves per groups is increased to reduce variability.

Influence of selected feeding supplements on the occurrence of coccidias in digestive tract of pheasants
ŠÍP, Pavel
The occurrence of coccidiosis is an enormous problem of pheasant farming. The aim of this study is to show, that this disease can be cured by unconventional dietary supplements. Dietary supplements which were used in this study were as follows: prebiotics (Ascophyllum nodosum), probiotics (Lactobacillus fermentum), homeopathics, Sulfacox and scrap from the seed by Vitis vinifera. The experiment took place in the Ranč Daniela farm in the town Hůrka (close to the Horní Planá Town) from 26.7.2014 to 5.10.2014. Six groups of pheasants were made - three experimental groups and one control group. All groups were consisted of 15 individuals. The pheasant Phasianus colchicus was used in this experiment. Dietary supplements were served for two weeks, than the serving stopped for two weeks and continued again. The samples of excrements were tested all the study long using the floatation method in Sheather's sugar solution. The results were marked and evaluated. The favourable effect of Ascophyllum nodosum, homeopatics and Lactobacillus fermentum on the intestinal tract of pheasant was significant.

Influence of selected feeding supplements on the occurrence of coccidias in digestive tract of chickens
PAZDERKOVÁ, Lenka
Taking preventive measures has a major impact on the overall health status of poultry in every breeding and it can prevent considerable economic losses in this way. The aim of this study was to obtain basic knowledge about the occurence of coccidia oocysts in the faeces and the occurrence of pathological changes in the intestinal mucosa of broiler chickens after the use of selected feed supplements. Experiment was made during winter 2013 and summer 2014 with 250 specimens of one-day broiler chickens. Four experimental groups (prebiotics, probiotics, homeopathy, coccidiostats) and one control group were created. Treated groups were administered by Selected feed supplements were served to chickens during 14 days since the sixth day of their life. Mixed faeces samples were collected twice a week and processed in the laboratory. Also the frequency of coccidia oocysts was monitored under the light microscope. Intestines were collected during the slaughters of chickens (five pieces from every group) and tested to confirm or disprove pathological changes associated with coccidiosis of poultry. Intestines were collected three times after seven days. The Reduced frequency of occurrence of coccidia oocysts in faeces of chickens in all groups of the winter and the summer trial period was demonstrated, while pathological changes of the intestinal mucosa were not proved.

Demarcation between the categories of products with physiological function on human body in EU law
Vavrečka, Jan ; Švarc, Zbyněk (advisor) ; Boháček, Martin (referee) ; Jakl, Ladislav (referee)
The thesis is focused on theoretical principles of demarcation of products with health effects in the EU law and on the reflection of these issues in the application and administrative practice in commercial law. The thesis developed yet been brought judicial interpretation with the scientific interpretation of certain key and decisive problems that separate from each other law-regimes of regulation: medicinal product for human use, foods, cosmetics products, medical devices and biocides. Correct law-regime for a particular product is determinating of the general legal basis in the EU internal market. It is therefore a important problem not only in EU law, but also in EU economic. Thesis results are highly critical of current practice in the local markets of EU member states, especially Czech Republic, and in many instances documented sub-optimal application of this law in general practice.

The occurrence of coccidiosis is an enormous problem of pheasant farming. The aim of this study is to show, that this disease can be cured by unconventional dietary supplements. Dietary supplements which were used in this study were as follows: prebiotics (Biopolym), probiotics (Lactovita containing bacteria Lactobacillus sporogenes) and homeopathics. The experiment took place in the Ranč Daniela farm in the town Hůrka (close to the Horní Planá Town) from 1.7.2012 to 18.11.2012. Four groups of pheasants were made - three experimental groups and one control group. All groups were consisted of 13 individuals. The pheasant Phasianus colchicus was used in this experiment. Dietary supplements were served for two weeks, than the serving stopped for two weeks and continued again.

Possibilities of the application of supplemental and nonconventional methods in prevention and health care in calves
KONRÁDOVÁ, Petra
Diarrheal diseases of calves are one of the most serious risks of rearing calves and cause economic losses. For this reason, the objective of this work was to assess the influence of means of support in operating conditions for the incidence of diarrheal disease in calves in the early post-weaning stages. A company was chosen for this work in which both the company employees and an external veterinarian were willing to collaborate and provide not only information about the breed in question, but also biological material. This company was JINOS - AGRO Veselí nad Lužnicí. The calves were observed in the period of April - June 2009. The calves were housed in separate boxes the second day after birth until the average age of 56 days. After storage, they were divided into 5 groups: 4 based on the chosen means of support, and a single control group. Faeces samples were collected from the calves and subsequently evaluated. The calves to whom were administered means of support were then evaluated to assess the effect thereof on the incidence of diarrhea, the duration of diarrhea, the method of treatment, and the duration of treatment. The results were summarized and analyzed using a statistical program (STATISTICA 7.0.). There was no statistically significant difference found between the individual groups and the experimental group. An evident and statistically significant difference was found only in the case of a difference between the drugs of the 2 experimental groups, specifically between Lactovita and Homeopatika. Based on this observation, it can be stated that there was no evidence supporting the effectiveness of administered means of support for the incidence of diarrheal disease in calves in the early post-weaning stages.

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.
