Current iodine supply to livestock
LÍKAŘOVÁ, Kristýna
The bachelor thesis deals with the evaluation of the current iodine supply of selected species and categories of farm animals based on it is content in milk. A total of 5 individual milk samples from cows from 5 farms and 5 pooled samples, 6 individual milk samples from goats from 2 farms and 1 milk sample from a mare were analyzed for iodine. The samples were collected in farms in the South Bohemian Region, Vysočina Region, Pardubice Region, Plzeň Region and Hradec Králové Region in 2023. Iodine in milk samples was determined using the Sandell-Kolthoff spectrophotometric method.

Monitoring parazitóz u vybraného stáda koz v ekologickém chovu a jejich řešení
KYNČLOVÁ, Nikol
The aim of this bachelor thesis was to monitor of endoparasites and the efficiency of deworming preparation on the ecological farm of goats. Anthelmintic resistance is becoming increasingly common in livestock farming, and its solution lies in sufficient prevention and the potential use of herbs in the future to support animal resistance, which can effectively complement the use of chemical preparations. Sample collection and examination was collected from May 2022 to March 2024 on an ecological farm in Peníkov, where 50 goats aged 1 to 10 years were monitored. Monitoring was conducted only on females, crossbreeds of the Anglo-Nubian and White Short-haired goat breeds, with samples taken randomly from goats with deteriorated fur quality, light eye mucous membranes, and results showing more than 200 EPG from previous samples. The resulting values were recorded, compared, and evaluated. The coprological examination revealed the presence of strongylid nematodes in the majority of samples taken, trichostrongylids, Ostertagia, and two samples with coccidia. Using the McMaster method, EPG values were determined for each individual fecal sample taken. The highest rate of infection was detected in May 2023, reaching 83,33 %. The findings indicate the influence of weather on the development and activity of parasites and their seasonal occurrence. Evidence of this is the high positivity rate detected in spring, at 77 %, and in autumn, reaching 75 %. The hypothesis of the highest rate of infectivity in young animals was refuted in the study, as 100% negativity was found in yearling goats. The worst values were observed in 4-year-old females with 87% positivity. Furthermore, the insufficient effectiveness of the deworming preparation was identified, with a FECRT for Eprinomectin set at 63,35 % reduction. Based on these results, prevention was recommended, a herbal mixture was proposed to increase goat resilience, and the use of a different anthelmintic was recommended to the breeder.

Occurrence of aflatoxin M1 in raw milk
UHLÍKOVÁ, Tereza
Mycotoxins, as secondary products of fungi, can contaminate feeds and enter the milk through the metabolic pathway in the cow's body. The most studied mycotoxin associated with milk contamination is aflatoxin M1 (AFM1). The review focuses on the identification of different types of mycotoxins and their transfer to milk, and attention is paid to a summary of the results of monitoring aflatoxins in milk and the negative effects of mycotoxins on health and the possibility of mycotoxins determination. The practical part of the thesis consists of two subchapters, namely monitoring AFM1 in raw milk of cows, sheep and goats in the years 2006-2020 from the data of the State Veterinary Administration of the Czech Republic, where the factor of the observed period and type of milk was evaluated for AFM1 content in raw milk. The second part interprets the results of AFM1 monitoring in purchased raw cow's milk delivered to the dairy factory.

Aspekty formování komoditní vertikály ovce
Goliášová, Renata
The diploma thesis is focused on identification of factors influencing commodity vertical of sheep. This vertical is compared with similar commodity of goat. The thesis classifies the development of this commodity on the market in Czech republic and compares it with the development in the market of EU member states. The study evaluates the development of sheep quantity status. The supply and demand side of the market as well as the proportional changes related to the foreign trade of the Czech Republic with this commodity are also examined. On the basis of the data determined by the market analysis, this commodity is evaluated. On the basis of the results obtained, it can be stated that the sheep commodity is only a marginal commodity in the Czech Republic and within the EU belongs the Czech Republic among the states with the smallest sheep population.

Péče o mláďata hospodářských zvířat v ekologickém chovu
Hledíková, Jana
This bachelor thesis deals with breeding of the young farm animals in organic farming. At first, the legislation related to the ecological system of farming is mentioned. Furthermore, objectives and rules of organic production follow. The principles of organic animal husbandry are described in more detail. The next part is devoted to specific types of farm animals, namely cattle, sheep, goats and pigs. The important aspects of rearing of the youngs, specifically housing, nutrition of females and youngs and weaning, are described in these livestock. Afterwards the comparison of organic and conventional farming system is made.
