Vliv přídavku quercetinu na výskyt kokcidií u králíků
Dvořáčková, Nikola
This thesis investigated the effect of the flavonoid quercetin on the coccidiosis oocyst counts in rabbits. At the same time, it also investigated the impact on weight, daily gains, feed conversation ratio, daily and total consumption, and biochemical blood parameters. The experiment lasted a total of 116 days. Two groups of six piece weaned rabbits each of the Japanese rabbit breed were created. The age of the rabbits was 35–149 days in the experimental group and 31–145 days in the control group. The average weight of rabbits at the beginning of the experiment was 267 g, and at the end, it was 2288 g. A special feed mixture containing 1.9% quercetin was prepa-red for the experimental group. The mixture was added in the amounts of 1, 2, and 4 g per day, depending on their equal weight. The addition of 0.01 – 0.04 g/rabbit/day of the flavonoid quercetin did not have a negative effect on the health status, performance parameters, and biochemical para-meters of the blood. The experimental group had a lower average number of oocysts (EPG) than the control group (quercetin = 328, control = 640). There was a statisti-cally significant effect of quercetin on the number of coccidia oocysts (P < 0.05), pro-bably through its antioxidant effect, supporting immune reactions, and thereby main-taining a healthy intestinal environment. Quercetin can be a potential substance for the prevention of coccidiosis.

Endoparazitózy ovcí na konvenčních farmách a biofarmách
Vomáčková, Karolína
The aim of this thesis is to assess the difference in prevalence of endoparasites in sheep bred on conventional farms and on organic farms. The theoretic part consists of a literary research on the basis of both domestic and foreign literature dealing with the problem of endoparasitic nematodes, tapeworms and coccidia in sheep. According to this research it is possible to identify seven perilous species of coccidia, fourteen species of intestinal nematodes, two species of lung nematodes, two species of tapeworms and two species of trematodes in the Czech Republic. The practical observations were carried out using nondestructive coprological techniques throughout the year 2016. Four species of coccidia (Eimeria bakuensis, Eimeria ovinoidalis, Eimeria parva, Eimeria crandalis), seven species of intestinal nematodes (Haemonchus concortus, Trychostrongylus spp.axei, Nematodirus spp., Cooperia curticei, Bunostomum trigonocephalum, Chaberia ovina, Oesophagostomum venulosum), one species of lung nematodes (Protostrongylus rufescens) and one species of tapeworms (Moniezia expansa) have been identified during the analysis. The prevalence of parasites and intensity of infection differed according to the type of farming, type of sheep care (incl. deworming) and also time of year. In total the organic farming has been assessed the healthier farming type. The practical outcome therefore is a recommendation for conventional farms to pay more attention to the sheep care with respect to the life cycles of the parasites.

Vliv chovatelského prostředí na výskyt endoparazitů ovcí na Tišnovsku
Vomáčková, Karolína
The aim of this thesis was to survey the problem of endoparasitic nematode, cestode, trematode and coccidia infections in sheep and their connection with the farming conditions and zoo-hygienic care. We have found out that 7 species of coccidia, 14 species of gastrointestinal nematodes, three species of lung nematodes, two species of cestodes and four species of trematodes can be found in local conditions. Further we discussed possible ways of suppressing the infections in the breeding environment. The practical coprological examination took place in autumn 2018. We've examined fecal samples from 10 different sheep farms in the Tišnov region, 100 samples in total. We've discovered four species of coccidia (Eimeria bakuensis, E. crandalis, E. parva, E. ovinoidalis), eight species of gastrointestinal nematodes (Bunostomum trigonocephalum, Cooperia curticei, Haemonchus contortus, Chabertia ovina, Nematodirus spp., Oesophagostomum venulosum, Trichuris ovis, Trichostrongylus spp.), two species of lung nematodes (Muellerius ca¬pillaris, Protostrongylus rufescens) and one cestode species (Moniezia expansa). Prevalence and intensity of the infection varied greatly among the farms. We concluded that administering feed supplements during lambing had the most noticeable positive effect on the infection course.

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.

Influence of selected feeding supplements on the occurrence of coccidias in digestive tract of hens
PAZDERKOVÁ, Lenka
Poultry farming represents 30 % of meat production worldwide. The occurrence of animal parasites is an enormous problem of poultry farming. This problem is recorded from factory farming as well as from small farming and causes financial losses. The aim of this study was to gain basic data about the occurrence of coccidia oocysts in the excrements of carrier hens. Carrier hens were fed by dietary supplements which were supposed to have influence on native gut microflora composition. This experiment was conducted on 26 individuals of carrier type hens. It was created the experimental and control group (one group consisted of 13 individuals). The experimental group was prebiotics (Biopolym), probiotics (Lactovita) and homeopathic served 14 days in and between each preparation was 14 days interval. The samples of excrements were tested in a laboratory once a week. The decrease of frequency of coccidian oocysts occurrence in the excrements in the experimental and control group was not proved.
