Preferences of the basic components of food by central European speciens of ants.
NOSKOVÁ, Lenka
This thesis has two parts: the first brings an overview of the role of various foods and nutrients in ants, the second presents the results of an experiment focused on preference of the basic components of food by central European species of ants. In the experiment we provided ants with six different baits (water, 1% sodium chlorid, olive oil, 20% amino acid glutamine, artificial honey [10% sucrose + 10% amino acid] and 20% sucrose). Total, 187 of 690 traps were visited by ants. There were 26 recorded species of ants. Preference of four most abundant species differed. F. polyctena attended most of the offered baits, while other species preferred the sugar components. In general, ants preferred artificial honey and sucrose, regardless of the season and habitats. Additional field tests with different bait concentration of salt and sucrose showed the same preferences regardless of bait type and no additive effects of the amino acid in the sucrose baits. The results of the experiment show a surprisingly consistent and strong preference of central European species of ants for sugars.

Zhodnocení kvality vybraných druhů krmiv a jejich využití ve výživě spárkaté zvěře
Vacula, Jaroslav
VACULA, J. Assessment of the Quality of Selected Types of Feed and Their Use in the Diet of Cloven Hoofed. Diploma thesis. Mendel university in Brno, 2014. From a wide range of animal feed have been described species suitable for use in the diet of hoofed animals. Samples from selected species of feed were collected in order to evaluate their quality. These samples were analyzed in an agricultural laboratory in Staré Město and their nutrient value and other quality indicators were determined. Quality of examined feed samples was evaluated and their suitability or unsuitability for nutrition of cloven hoofed was assessed. Based on the results, it was recommended which types of feed is appropriate to use for the nutrition of cloven hoofed, how to treat the feed and submit it to animals and were assessed risks of feedeing by selected species of feed.

Účinek hnojení na eluci živin z půdy
Kučerová, Věra
The focus of the dissertation was on the evaluation of the effect of fertilisation on the elution of nutrients from the soil in various soil and climate conditions. The results were used of long-term stationary experiments conducted at the ÚKZUZ (Institute for Supervising and Testing in Agriculture) by means of lysimeter measurements and monitoring of meteorological data taking into account the respective production region. The trial plots are located in various parts of the Czech Republic therefore we can compare the results of experiments according to the soil-leaching regimes, various degree of fertilisation on arable land etc. Three crop rotations were evaluated (1989 - 1996, 1997 - 2004, 2005 - 2012). The most severe losses caused by washing out were losses of calcium, sulphates and nitrate N. In the case of N and K the balance of nutrients (uptake -- outflow) was in most cases negative with the exception of potato growing. This negative balance is based on the higher outflow (withdrawal by yields + washing-out losses) as compared to the lower input (nutrient uptake from fertilisers + precipitation). The balance was more negative in the BVO (potato growing region) with a soil-leaching phase than in the ŘVO (sugar-beet growing region) where the soil-leaching regime was periodic. Adequate and harmonic fertilisation is the prerequisite for a balance of nutrients respecting the actual yields.

Obsah živin a charakter půdního sorpčního komplexu u vybraných půdních typů
Němec, Jakub
Diploma thesis " Nutrient content and character of soil colloidal complex in selected soil types " is aimed at chemical properties of Haplic Chernozem, Haplic Luvisol, Haplic Cambisol, Gleyic Stagnosol and Calcaric Leptosol. Obtained results were compared with Systematic Soil Survey (1965 -- 66). Loss of humus and higher acidity was determined in Haplic Chernozem. Other soil types were low or middle low in nutrient content. Quality of humic substances was also low and there is necessary to improve nutrient regime and humus content in arable soils.

Chemická a biologická charakteristika kambizemí v průběhu dlouhodobého pokusu
Klein, Martin
Diploma thesis is aimed at chemical and biological parameters of Cambisols. Se-lected subtypes were studied in Český Krumlov region (Stagnogleyic Cambisol at local-ity Desky and Haplic Cambisol at locality Malonty). In Třebíč region -- Haplic Cambi-sol (Náměšť) and Leptic Cambisol (Ocmanice) were studied during the period 2008 -- 2013. We determined active and reserved soil reaction, conductivity, nutrient content, and total organic carbon content, fractional composition of humus, humification degree, quality of humic substances in UV-VIS spectral range, bacterial biomass and soil basal respiration. Obtained results showed statistically significant differences in humic sub-stances content after compost amendment.

Hodnocení krmných dávek sportovních koní
Müllerová, Simona
The aim of the thesis was to evaluate the feed ration of sport horses on the farm Elevage The Field in Switzerland. A total of 18 horses of various breed, age and workload were selected for evaluation. Their workload and daily food intake were recorded for five months. This period was divided into two periods (from February to April and from May to July). Horses were divided into two categories, namely the group of working horses and the group of horses without a workload (young and convalescent horses). Condition of both groups of horses was evaluated according to (BCS). Further, the need for nutrients was determined and the calculation of feed rations was performed according to the standards of NRC (2012) and Zeman et al. (2005). Both standards were then compared with each other. After that the adequacy of dry matter, SEk, NL (SNLk), fat and fiber intake was assessed . It was found that the technique of feeding and the way of breeding mostly meet the needs of sport horses. Based on the comparison of needed and received nutrients, it was found that the dry matter, fat and fiber intake is adequate for both groups of horses. However, most rated horses recieved more of SEk and NL (SNLk) than their daily need. Both used standards can be considered comparable in calculation of SEk; in terms of content of NL (SNLk) there are some differences. The standard by Zeman et al. (2005) is much stricter in this regard.
