The goal of the thesis was to evaluate the influence of stabling technology change and feeding during a stanchion barns (type K-174) reconstruction to free barn housing. The monitoring was carried out from January 2015 till February 2016. Based on the data obtained from the efficiency control for testing individual samples of milk (Milk Profit Data application) and values of pool samples during individual months were evaluated these parameters: total daily milk production, components of milk and health of dairy cows. In September 2015 were the dairy cows moved from stanchion barn into temporary conditions. There was the change of the feeding technique, housing system and milking. On the 16th December 2015, cows were moved into the newly renovated barn with a new milking house. After completion of the stress effects, there was an overall improvement of living conditions of cows. There could be seen significant improvement of the milkings hygiene which led to reducing CPM and PSB. It had an impact on cows health improvement. The change of the feeding technique also helped here. Former individually feeding components were replaced with mixed ration TMR. This resulted in a stabilization of rumen ambience, which reflected on the milk components balance. While in stanchion barn, results showed to diets errors and incidence of metabolic disorders such as acidosis, alkalosis, ketosis and diseases of mammary gland (mastitis). The results of the thesis document largely positive impact of mentioned changes - stabling technology, milking and feeding - on evaluated efficiency parameters, milk quality, milk hygiene and also metabolism of cows.

Diploma thesis: "Evaluation of growth intensity and meat production of fattening bulls on a specific farm" aims to evaluate the intensity of growth in fattening bulls Agricultural Society as Vítějeves. Evaluation of growth intensity was carried out on 142 bulls of different breeds. Animals were weighed on a quarterly basis according to the weight divided into groups. For each group of animals was measured statistical conclusiveness between weight and additions. Throughout the feed lot bulls were found in the period December 2011 to December 2013 the average weight of 462 kg, average growth was weighing between 918 g.day-1 and average daily gain since birth g.den 998 g.day-1. To evaluate the meat yield of the bulls from the Czech pied cattle breed, the weight was taken on 120th, 210th and 365th day of age, the average daily weight gain since birth was calculated, the average daily weight gain between taking the weight and the weight of body prepared for slaughter was calculated by 1.78 ratio on the animal's weight before the slaughter. Subsequently the effect of the weight, the gain and the slaughter parameters on the slaughter age was assessed and the netto gain and classification to the SEUROP system classes as well. The bulls of Czech Fleckvieh breed average increased within one year of life 774g.day-1, after the one-year increment increased to 967 g.day-1. The average gain from birth to slaughter was 967 g.day-1. Most bulls were slaughtered before the age of 650 days, and their slaughter weight was about 632 kg. For SEUROP bulls were mainly included in class R2. Carcass weight was about 350 kg.

The aim of the dissertation is evaluation of relation between utility properties and economics of breeding cattle - breed Charolais at the chosen farm. Especially breeding conditions and zootechnical measures with their effects on the economic results in years 2009 - 2014. There is in the literatury searches described the principle of breeding cattle and its economic conditions in the Czech Republic. Further history, characteristic of the breed and its breeding standard. There is chracterized the current state and expansion of the breed in the Czech Republic and France, the country of origin. The way of the checking the utility and the monitoring of decisive utility properties is written here. The work was done in the farm Komensko. The farm is focused on crop production with 696ha and breeding cows without a market production of milk with 102ha meadows and pastures. There is currently bred 76 pieces in the basic herd. The herd is before completion of the transmission crossbreeding owing to repeatedly mating of bulls Charolais. The achieved results of the reproduction are good thanks to replacing insemination natural breeding. Reserves were found in growth capabilities of calves, when monitoring weights on the 120th, 210th and 365th day were lagging behind the average in the Czech Republic and France. The achieved sales display an increasing trend, but are constrained by the expansion of basic herd and accelerated eliminate of cows with participation milk breed. The farm shows a profit during the monitoring period. The farm had the highest profit in 2014 and it was 431 823.- CZK. By contrast the farm had the lowest profit in 2010 with the result 18 035.- CZK. Generally we can say the farm had the highest profits in the last free years. That happened because of the increasing revenues from the sold animals and higher income from the subsidies. Promise for the future is to finish the transitional process and to allow selling the breeding material instead of the cattle for a much better price.

The aim of this thesis was to evaluate the level of mating on the farm using controlled herd reproduction. The evaluation of the level of pregnancy was carried out in dependence on the individual month of observation, the monitored parameters of milk from the performance control of individual lactations and the lines of fathers of cows. Performance data for January 2017 - April 2018 were used for the assessment. Based on the result, it can be concluded that the seasonal percentage is affected by the season. It has been shown that the percentage of pregnancy has decreased in the summer month. The significant decrease in the rate of mating was occurred with the increasing age of cows. The percentage of lactation, regardless of the order of lactation and the line of bulls, is negatively influenced by the milk yield and by the positive effect of the number of lactation days when embedded. To confirm the negative effect of milking yield on the breeding, the NEB breeders showed the highest milk yield and the lowest percentage of pregnancy. Significant fluctuation were occurred in value when evaluating individual indicator depending on the reference month. In the middle of the reporting period, the amount of urea in the milk had a positive effect on pregnancy. A similar result was obtained for the T / B ratio.

Poultry meat is in the range of basic human nutrition. In human nutrition has a significant position mainly due to its composition. It is especially valuable for high-quality protein. They are very easily digested and contain all the essential amino acids. Aim of this study was a comprehensive analysis of the level of commercial properties in broiler chickens and their final hybrids. The analysis can bring about recommendations for breeders in the selection of suitable hybrid combinations in our conditions. Parental self-test forms consisted of rearing parents until the age of 154 days, the laying period of 280 days and four sub-fattening progeny tests. Rearing, laying and fattening progeny took place in the hall without windows, with deep bedding with controlled lighting and air conditioning regimen. The tests were performed 4 sub-fattening progeny tests using a load of 17.2 units chickens/1m2, length of fattening period was 35 days. The data were obtained with the consent of management of the primary data a comprehensive report of international tests and parental forms of broiler fattening sub-tests carried out in the final hybrid MTD Ústrašice for the years 1995 to 2009. These tests were made by MTD and methodology based on the guidelines for the implementation of performance tests of poultry. The data obtained were classified, summarized, and then the variation statistically using STATISTICA version 6. By comparing the results obtained from the parents and fattening tests it can be stated that, overall, the best combinations were Ross 308 and Cobb 500.

The aim of the diploma thesis was to evaluate the level of reproduction and kid rearing of the selected goat herd and to evaluate the milk production of the herd. The practical part of the thesis evaluates the results achieved on a selected family farm with goat breeding. In the period 2015-2017, the total dairy yield of the herd was recorded. In 2017, the level of reproduction and kid rearing was also monitored. The detected values are then compared to the average data achieved in performance testing in the given years and the results of foreign studies on a similar topic. Herd fertility was rather average and reached 136 %. The percentage of kids reared by 1 goat was 112 %. Dairy production per 1 goat for lactation was rather below average, it was 437 kg in 2015, 414,4 kg in 2016, and 347,2 kg in 2017. The percentage of fat, protein and lactose content was comparable to performance testing values. In the end of the thesis several modifications are suggested to improve the organisation of goat breeding on the farm.

The thesis is focused on the comparison of the influence of different types of starters on feed intake, holstein breed calf increments, feed conversion, economy, rumen fluid and blood parameters during calf rearing. After the colostrum period, the calves were divided into 3 groups of 5 individuals, they were fed by dairy feed mixture and various types of starter mixtures. The first group had ČOT – B granular starter (granulated granulated components), the second group received Premiumstart – muesli and the third group got Goldstart – a mixture of granules, corn flakes and cut straw ("straw starter"). In 60 days old they were bled and then killed in a slaughterhouse. After slaughter, the rumen and rumen fluid were collected from the calves for subsequent analyzes. The average starter consumption and feed conversion was the highest in the second group. The average daily increase was relatively balanced in the individual groups. The load per kg increment and the real starter consumed was demonstrably the lowest in the first group. The average pH of rumen fluid was significantly lower in the first group (below 5.5). Propionic acid was relatively high in all calves (up to 15% in the first group, 9% in the second and third groups) and low levels of acetic acid (8% lower). A low number of ciliates was found in all groups, but in the third group level was close to the reference values of adult cattle (119 thousand / ml). In calves received Goldstart starter straw, rumen fermentation values were closest to the physiological rumen environment. In this group of pH, the number of ciliates and the proportion of acetic acid and propionic acid corresponded. In terms of rumen papillum development, rumen volume, ammonia, pH, WBC, and ALP levels, Premiumstart – muesli is the most appropriate. The WBC concentration was highest in calves that received muesli starter. The highest glucose levels were observed in calves that received the ČOT – B granulator starter. The highest levels of ALP were found in the calves that received the muesli starter, which can be confirmed by the highest daily gains in these calves. The results obtained give a good idea of the functioning of the individual starter mixtures. However, for practice, it will be necessary to repeat the experiment to confirm some claims.

The aim of this thesis was to compare the indicators of egg production of hens which are bred for production of consumable eggs i.e. Hy-Line Brown and Hy-Line White in selected farms. Selected parameters of egg production were evaluated during 12-months-laying cycle. In the selected farm during the monitored period was achieved the intensity of laying 86,8 %, laying at the initial state 26.5 eggs, number of eggs included in first quality class 96.4%, mortality of egg layer 1.06%, consumption of compound feed per 1 egg 130.0 g and consumption of compound feed per 1 feeding day 110.8 g. Hy-Line Brown showed higher intensity of laying (88,0 %, respectively 85,2 %), laying at the initial state 26.7 eggs, respectively 26.1 eggs, lower consumption of compound feed 128.7 g, respectively 133.2 g. Hy-Line White showed a statistically significant higher proportion of eggs included in the first quality (97.3%, respectively 85.4%), statistically significant lower mortality (0.49% and 1.51%) and statistically significantly lower consumption mixtures per 1 egg (100.7, respectively 114.9 g).

The aim of the work was to observe effect of Elo Macro preparation of milch cows. For two months the experimental group (n = 36) was given feed enriched with 5 g brown seaweeds Elo Macro preparation but the control group (n = 34) was not. The experiment was repeated. In the second experiment there were the experimental group (n = 23) and control group (n = 23). The effect of brown seaweeds in preparation Elo Macro was tested: dairy production, index P 2:1, average fat, protein and laktose, all in milk, number of somatic cells, number of inflammations milk gland, parameters reproduction, specific gravity of colostrum, weight and vitality in calves after birth. The effect of the preparation brown seaweeds was not statistical significant. The positive effect was found out in the day dairy production and a milk protein.
