Nutritive value determination of granular feed mixtures for dogs
ZNOJ NOVOTNÁ, Barbora
The aim of this thesis was evaluate the nutritive value of complete granulated dry food for adult dogs in normal activity. 17 dry feeds were choosen with regard to quality classes - 7 superpremium, 5 premium and 5 economy. Content of moisture, crude protein, crude fat, crude fibre, crude ash were determined in laboratory and NFE (nitrogen-free extracts - carbohydrates) and metabolizable energy were determined by calculations. The results of the analysis were compared with figures stated on the packaging of the feed. Quality classes were compared with each other. It was found that 12 from 17 feeds exceeded the tolerance limites for declarated nutrients. Not all of the feeds on the market is suitable for the dogs and an appellation superpremium isn't guarantee of good quality.

Amaranth unconventional food in human nutrition
ŠESTÁKOVÁ, Irena
The subject of the Bachelor thesis is amaranth as an innovative component in human nutrition. Genus Amaranthus L. belongs to the family of Amaranthaceae. Amaranth is an annual dicotyledonous C4 plant. The seeds are smooth, lenticular and in cultural species are pink or yellow up to cream-colored. In the Czech Republic the weight of thousands of seeds circles around 0.6 to 0.8 grams. The whole aboveground part of the plant is edible. Usually people consume only seeds and leaves. Plant species grown for its seeds are Amaranthus hypochondriacus, Amaranthus cruentus and Amaranthus caudatus. Some species are grown as a leaf vegetable, such as Amaranthus tricolor, Amaranthus dubius and Amaranthus gangeticus. Plants are resistant to the higher salinity and have increased ability to draw nutrients from the soil. The plants are able to manage with the supply of soil moisture; therefore it fits also in drier areas. During the vegetation it is necessary to get rid of weeds, especially removing related wild plants whose seeds cannot be separated from cultural forms. Amaranth seeds ripen unevenly. The date of the harvest is selected depending on the variety, sowing date and weather conditions. Suitable storage humidity is 12%. Yield in our conditions varies between 600 and 2400 kg / ha. The estimated yield per hectare varies between 4 and 14 tons of fresh leaves. The use of amaranth in food industry has a wide range such as bakery, meat industry, children's nutrition, pharmaceutical industry, cosmetic industry and energy industry. Amaranth is from the nutritional standpoint, highly prized plant. The content of proteins is about 18%. Amaranth protein is important in terms of higher lysine content, therefore if it is appropriately used in someone´s diet, it can replace animal protein. Carbohydrates of amaranth are listed in quantities of over 60 %, the most important carbohydrate of amaranth is starch, which has an extremely small grain (1 2 ?m) and it is useful for nutrition, where it can be part of easily digestible nutritional beverages and products. Fats of amaranth are in the range of 6 - 8 %. From the dietary point of view, it is important to sustain high content of unsaturated fatty acids and squalene, which is known for its antioxidant and chemoprotective effect. Another components of amaranth oil are phytosterols, which have a preventive effect against atherosclerosis. Other important ingredients of amaranth are substances such as phenolic flavonoid rutin, which increases the resistance of capillary walls and improves the absorption of vitamin C in the intestines. Amaranth is an excellent source of vitamins and minerals. However, Amaranth grain and leaves also contain anti-nutritional and toxic substances. By the influence of the selective breeding, way of storage and processing such substances in the plant gradually decreased. Researches have shown that amaranth has wide preventive effect. It does not cause any allergic reactions and does not contain gluten. For that reason it is suitable for inclusion in the diet of coeliacs. Amaranth contains antihypertensive peptide and in diabetics it reduces the risk of a lack of insulin in the blood and it has been shown and anticancer effect. Eating amaranth has a positive effect on the immune system and body supply of iron. Amaranth is also a good ingredient in nutritional drinks and enteral nutrition. The suitability of this crop in the diet of all age groups is indisputable. In seniors it affects cell regeneration and metabolism, and in children the importance of lysine, which promotes the formation of new brain cells. Amaranth is for its toughness and content of many nutrients, minerals and vitamins referred to as the third crop Millennium, which may be one of the solutions to food shortages in developing countries.

Specific nutriton as a means of own self-creation of human pesonality - athletes. Case Study
TEPLÁ, Kateřina
Modern times bring a number of new views on the perception of the meaning and role of nutrition in human life. Observing the current lifestyle we can see considerable differences in particular individuals. This work deals with the problem of specific nutrition in connection with a regular sport activity as contributory factors which create the lifestyle of a sportsperson. This work concentrates on the individual for whom the strict and specifically focused nutrition in connection with a regular sports activity creates an inherent part of their life and is therefore the way to fulfillment ? to self-assembly in numerous directions. The goal of this work was to describe the composition of diet and its changes connected to different stages of a sportsman´s ? body-builder´s training plan. To map possible bio.psycho-social consequences. For the implementation of this research a qualitative research strategy was chosen. The research was carried out as a case study. The reference file has been made of a couple of sportspeople-body-builders. A woman and a man representing the current trend of fitness ? body-building followers for whom the connection of sport and well-focused nutrition represents one of their life´s values. The research was implemented in a wider timeframe, in a frame from May 2012 to January 2013. Semi-structured interviews, observation, evidence of different personal documents and activity results were used as data collecting methods. For the data analysis a qualitative analysis of written-down interviews, observations and personal documents, and activity results was carried out. From the conducted research of the particular case it was further found out that the nutrition of a body-builder changes during the different stages of the training preparation, even in rapid ways. Changes of the total amount of food, the change of the ratio or amounts of particular nutrients as well as changes in the choice of consumed food are observable. The observed changes of the sportspeople´s eating correspond with the theoretical knowledge given in the theoretical part of this work. At the bulk stage of this work the eating of the observed couple was characterized by a relatively high intake of energy, especially as the permanently higher intake of carbohydrates, a high intake of proteins and out of all the stages by the highest demanded feed of fat. In the cutting phase of the preparation the food of the observed couple was characterized, on the average, by a lower intake of energy, especially thanks to the limitation of the intake of carbohydrates, by the same or higher amount of proteins than at the bulk stage. The intake of fat in the man´s food basically didn´t change, but the woman decreased the amount of received fat compared to the bulk stage. At the final stage of the preparation the food of the woman was absolutely specific. During the resting and recovery phase of the preparation the eating of the observed couple did not show any strictly given requirements. Out of the research results it is clear that the sportspeople´s approach to food is varied, it differs according to the phase of training preparation. Food can be therefore either an enjoyment or the need to a sportsperson. For the observed couple, food isn´t a taboo. This specific and to some extent extreme lifestyle brings certain positives and certain risks with it. This work can be used as an information material for nutrition therapists focused on working with sportspeople, and for informing sportspeople themselves as well as the wider society about the possibilities of the effects of extremes in nutrition.

Characteristics of crude protein fractions in ruminant nutrition
KOUKOLOVÁ, Marie
Physiology of nutrition and feeding of farm animals is an essential factor influencing production efficiency and its quality. For these factors is important to provide optimal supply of nutrients by suitable feeds. Felicitous feed ration raise the economic realization of genetic potential of animals. Therefore we have to know the nutritional requirements of animals, including microorganisms, whose function in the diet of cattle is irreplaceable. The aim of this study was to determine the nutritional value of forage and lupine feeds (n = 8) by laboratory methods. Samples were analyzed for individual feed nutrients (crude protein (CP), fat, crude fiber, ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL)), gross energy and nitrogen fractions, and the results were statistically processed. Determination of individual nitrogen fractions was according to methods of Licitra et al. (1996). For this purpose were used following laboratory methods: (1) determination of non-protein nitrogen (NPN) (2), determination of soluble nitrogen and protein, (3) determination of nitrogen insoluble in acid detergent (ADIP), (4) determination of nitrogen insoluble in neutral detergent (NDIP). From these were obtained the results of NPN, IP (insoluble protein), SOLP (soluble protein), ADIP (nitrogen insoluble in acid detergent) and NDIP (insoluble nitrogen in neutral detergent). Averaged values (g.kg-1 of dry matter) of were 144.3 for NPN, 97.5 for IP, 78.7 for SOLP, 30.4 for ADIP and 80.3 for NDIP. Nitrogen fractions, i.e. fraction A (nonprotein nitrogen), fraction B1 (rapidly degraded protein), fraction B2 (intermediately degraded protein), fraction B3 (slowly degraded protein) and fraction C (bound protein) were calculated by equations of Ghoorchi and Arbabi (2010). The range of values was from 2.5 to 51.2 % of CP for fraction A, from 13.4 to 20.7 % of CP for fraction B1, from 0 to 19.9 % of CP for fraction B2, from 5.5 to 51.9 % of CP for fraction B3 and from 10.1 to 32.4 % of CP for fraction C.
