The aim of this dissertation was to analyze the relation between the growth intensity of Czech Fleckvieh heifers and their milk production. The dissertation can be divided into five parts. In the first part, the age, weight and average daily gain of the heifers was determined. For the whole research period, 8985 individual weighings were performed. In the second part of the dissertation, the condition of 538 heifers together with the measurement of their cross height was evaluated. In the third part of this work, weighing of live weight of heifers was assessed in relation to their subsequent milk production, which was found in 1867 breeding females with 4536 weighings. The fourth part of the thesis evaluated the effect of age at first calving on selected indicators of milk production in individual lactations in 7871 milk cows. In the fifth part, the influence of the daily gain of heifers on selected meat production indicators was analyzed, where the total number of analyzed heifers was 480 pieces. All the evaluated breeding females were recorded in the main section of the Czech Fleckvieh herd book. In cases where the average daily gain of live weight was measured, the weight of the calf at birth of 32 kg was taken as the initial live weight. The statistical evaluation of the results was carried out in the SAS program. Evaluating the growth of heifers, good results of BCS were achieved by heifers with a high intensity of their growth. The heifers, which reached the highest gains, also had the highest cross height values. Furthermore, it can be stated that the average daily gain of 0.801 to 0.999 kg/day is optimal, as for the milk production, for the heifers aged up to 7 months. An optimal daily gain of older heifers was over 1.000 kg/day. In this dissertation, it was confirmed that the ideal age for the first calving is in the range of 23 to 26 months. When analyzing the beef production of heifers, it was proven that the breeding cows with higher daily gains achieve better classification and heavier carcass weights.

The aim of this diploma thesis was to analyze reproductive performance of sows in the selected breed. In this breed, data was collected in the year 2016 and early 2017. The basic statistical characteristics were monitored for the number of all pigs born, the number of live births and the number of weaned piglets evaluated for the influence of litter rank and the influence of the boar used. The test data was tested by paired t-test. The total number of sows with reproductive parameters was number 63. The number of live piglets in the monitored period was 12.9 pieces / litter. The indicator of the number of weaned piglets was 11.9 pieces / litter. The highest average number of live-born piglets was 36 for boar, but for the change had the highest piglet losses against other boars. The litter's influences on the number of live-born piglets was 12.8 pieces / litter in the 2nd litter and in the 3rd litter 13.5 pieces / litter, this difference was statistically significant. It follows that the highest average number of live piglets in litter rank was reached on the third litter order.

The master´s thesis analyzes factors impacting on efficiency of sows and mortality of piglets. The data evaluated in this thesis comes from 54 sows and 513 piglets they farrowed. It focuses on impact of particular factors on length of meantime, order of litters, birth weight of piglets, litter size, hybrid combination and individuality of the boar. Longer meantime have shown a trend of increased number of stillborn pigs and higher parity has shown shortening of meantime. Statistically highly demonstrable difference (p < 0,01) can be seen between the sixth and higher litters and the third litter. Statistically demonstrable difference can be seen between the fifth and the third litter (p < 0,05). Higher birth weight has shown decreased losses of piglets. At the same time a negative correlation has been observed between the litter size and the birth weight, resulting in proving a statistically highly demonstrable difference in the number of all born, live born and weaned piglets between the group of the heaviest subjects and the groups of lighter ones. While observing differences in hybrid combinations (CLW x CL) x CLW sire line and (CLW x CL) x D, considerably higher losses of piglets have been observed in the first group and while observing the impact of individual boars, notable differences in weight and losses of young pigs have been observed.

The aim of this thesis was to evaluate the reproductive performance parametres in sows in selected herd of the years 2010, 2012 and 2013. In the year 2011, the selected herd has been repopulated, therefore the results from this year are not included in this work. There were observed phenotypic levels of selected reproductive parametres, namely the total number of born piglets, the number of live -- born piglets, the number of reared piglets, the comparison among parities. Further, there were evaluated the loss of piglets, lenght of meantime and rate of conception of sows. The obtained results indicate that the best results of the reproductive performance parametres in sows was reached in the year 2013, namely 33.6 pcs of total born piglets/sow/year (14.26 pcs/litter), 30.7 pcs of live -- born piglets/sow/year (13.03 pcs/litter) and 26.4 pcs of reared piglets/sow/year (11.21 pcs/litter). In comparison of parities, the best results were found on the third and subsequent litters, namely 14.76 pcs of total born piglets/litter and 13.64 pcs of live -- born piglets/litter in the year 2012. The highest number of reared piglets was found on the second litter in the year 2013, namely 11.57 pcs/litter. The evaluation of losses of piglets, the highest level of losses of live -- born piglets was found in the year 2013 (14 %). The highest share of losses of piglets from birth to weaning accounted piglets with low birth weight. In selected herd, the measures have been taken to minimize loss of piglets, five percent at least. In the evaluation of lenght of meantime, there was found the shortest length in the year 2012, namely 149.5 days. The best rate of conception of sows was found in the year 2013, namely 94.6 % after the first insemination.

The aim of this thesis was to evaluate the effect of environmental changes on longevity and milk production of cows Czech Fleckvieh cattle in selected breeding. The work focused on the comparison parameters milk production, longevity reasons decommissioning cows and lactation on which the cows were excluded. Within one company were monitored two groups of cows. The first group of cows was monitored in the original stabling. The second group consisted of pregnant heifers whose milk production have been monitored in subsequent years. They were removed to new stabling among cows of Holstein cattle. Each of the groups had different environmental conditions, treatment and different feed ration. Milk production and longevity of cows were evaluated in six years. In the framework of the obtained results it can be concluded that the change in the environment, treatment and feed ration were the main reason leading to the increase in the milk production of cows in the new location. Cows in the new stabling were mostly eliminated because of the reproductive disorder, milk production and other reasons (mortality, high age, diarrhea, poorly developed teats, bad condition).

In this thesis, it was analysed the current nutrition of cattle especially in calves and cos, because nutrition plays a signifiant role in these categories, leading to the following high milk production. The content of the work is mainly focused on the nutrition of dairy cows and their performance when feeding different feed rations, which were presented to the time in the years 2013/2014 and 2015. Ration differed only in the administered of the product B, when TMR Balance from the time this was shot administered from May 2014. The observation took place on private agricultural farm in Podkrkonoší. The farm was observed a group of dairy cows, mostly Czech pied breed, which had a combined 34 pieces, 4 Holsteins and 30 Czech pied breed. The group of animals arrived in the feed ration years 2013/2014 without granulate TMR Balance B and the same group of dairy cows, then began to submit feed ration with granulate. Statistically are evaluated on the first lactation cows, which were given the first shot immediately after calving. A group of cows which was observed on the first lactation include 11 cows. The work was observed their performance according to the above data form performance tests conducted by the Bohemian- Moravian Association of breeders. On the basis of the results achieved can be stated, that the preparation of TMR Balance B added to the diet increased the productivity of dairy cows on the farm, because the settlement has occurred, the ration supply a sufficient amount of vitamins and minerals needed to produce more high - quality milk and better health of dairy cows. Milk yield of milk is according to achieved and evidence of the results of picking up on the 614,64 kg in 305 days of lactation, on the 802,91 kg in 200 days of lactation, on the 371,59 kg in 100 days of lactation. Demonstrated also increased the performance of the protein for the 28,93 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.

Milk yield of dairy cows is mainly determined by their nutrition and state of health. Dairy cows turn roughage into milk the most effectively. The assessment of the level of nutrition and the processing of silage and haylage was performed in operating conditions. Quality of roughage, technique of nutrition and its influence on milk yield in stanchion-tied stable were assessed. Data were observed over a peri-od of 3 years (2012 2015). The observation included Czech Fleckvieh Breed and Holstein Breed. Average daily yield data were monitored with all dairy cows, which were in lactation period during the observation. The gained data were entered into diagrams and charts and evaluated. The highest performance results have been achieved in 2015, the lowest performance results have been achieved in 2013.

The aim of diploma thesis was to analyze an ecological farm in South Bohemia region with the system of beef farming with the exclusion of market milk production, and evaluation of selected reproductive and meat production parameters. Meat hybrids of aberdeen angus, galloway, charolais and hereford breed were kept on this farm. Years from 2010 to 2015 were analyzed and then following parameters were evaluated: number of births during the year and in individual months, length of gestation and calving interval, service period, insemination index and calf losses. Meat production indicators were evaluated including the resulting class of carcase classification in SEUOP system, carcase weight and the age of animals at the time of slaughtering. Subsequently, comparison with neighboring organic farm and conventional farms were made. Although it is a small farm the results of the analysis shows that the reproductive parameters are above the average compared to the conventional aberdeen angus farms. Comparing conventional farms meat production results are relatively the same.
