The aim of this work was evaluate the productive indexes and appreciate the behaviour of beef cattle dams reared in the system of breeding cows without market milk production. The analysis of the beef herd was performed in the agricultural company farming in above sea level altitude 650 meters. Through the years 2001 - 2006 was evaluated reproduction indexes by dams of basic herd and calves growth ability. Ethological monitoring was important for appreciation welfare conditions of breeding. Monitoring went ahead in single yearly periods in luminous parts of the day. Tracked group formed 31 pieces of dams, calves and sire.

Iodine content in excrement. Calibre was locate from 430 {$\pm$} 142,4 {$\mu$}g {$\bullet$} kg-1 bis 6182,5 {$\pm$} 2625,6 {$\mu$}g {$\bullet$} kg-1 dry matter and average 2299,2 {$\pm$} 884,3 {$\mu$}g . kg-1 dry matter. Relation was low from between idoine content in excrement and iodine reception. Environment was not contaminate.

The point of the work was to make an analysis of milk production an and fertility and to attest dependence of milk production and fertility in the holstein cattle herd. Background materials were acquired especially from milk production control and cattle accompanying documents. Data of 251 dairy cows were worked up. Big problem of the high producing dairy cows is the low fertility. That is why the work was focused on analysing of milk production and fertility index. Service period, insemination interval and interval were analysed out of the fertility index. Milk production, proteins and fats percentage content represent the efficiency. The results show the high selection of cows out of the herd. It result shows from a number of included heifers. Most frequent reasons of selection are health condition, low milk efficiency and fertility disorders. Average efficiency in control increases. On the other hand the protein contest in milk is weak. A breading aim 3,3% was achieved only in year 2003 (3,32%). Milk production increases from the first to the third lactation. Milk production is decreasing from the fourth lactation. Fat percentage content increases to the third lactation, then it stagnates. The protein content goes down with number of lactation. Required interval length to 400 days is exceed in all lactation. Service period is to high regardless of lactation number. Insemination interval increases to the third lactation, then it decreases, but it is nonconforming all the time. The results show that fat and protein content decreases with milk production. The high milk production was reached on cows calved in autumn (8920,77 kg) and in winter (9231,48 kg). Data of cows calved in spring and in summer are almost the same. The results evidence general rule, that fertility decreases with increasing milk production.

The thesis is focused on the comparison of several types of microclimates in enclosed places of livestock production, aimed at beef-raising. The goal is a making the comparison of final results of microclimate elements at two sorts of stabling. Stanchion housing versus opened housing.

With increasing consumption of milk and milk products, there were increased number of dairy cattle, but the increase of demand for dairy cows and thus to changes in technology and technique of milking, which would increase milk production, productivity, and improve the welfare of dairy cows. An efficient solution could be milking robots. The first robot was placed on a farm in the Netherlands in 1992. The introduction of robotic milking on agricultural farms in the Czech Republic began in 2003 when the main reason was a shortage of skilled manpower that would be willing to work in harsh working and sanitary conditions. The thesis aim was to assess the effect of milking by the milking robot on the behavior of breeding cows throughout the day in relation to milk yield and fertility in relation to lactation and genotypic classification (H100, HxC, C100). The behavioral monitoring was carried out in dairy farms Brloh (milking by milking robots) and Haklových Dvorech - the control group (in the milking house) in the period from August 2009 to January 2010. The data processing was done with using the Microsoft Excel program. For the evaluation of all parameters were observed in herds calculated basic statistics. Differences disappear individual indicators were evaluated single-factor analysis of variance. The first monitoring of the findings in cattle reproductive performance was the terms of genotype. The values were found favorable for fertility groups HxC in the both stables. Length insemination interval reached 69.1 days in ZD Brloh (compared to 110.1 of the ŠZP Haklovy Dvory), length of service period of 110.8 (vs. 142.9 days). In the meantime, the length (due to differences in the number of animals in the group) was a length of 409.5 versus 438.5 in the group of breeding cows milked in a milking house (ŠZP Haklovy dvory). Further indicators of fertility were evaluated in terms of lactation. The longest length of service period was recorded at 1st lactation in ŠZP Haklovy Dvory were 176 days. The shortest service period was found at the 3rd and subsequent lactations of 133.5 days. Insemination interval, indicating the search of breeding cows, which were in a rutting season, was roughly the same at all lactation ZD Brloh (range 72.7 to 78.2 days) for the ŠZP Haklovy Dvory was the longest period of time to 2 lactation (118.9 days). In terms of breeding cows for milk yield for each lactation cows achieve greater results in the production company with robotic milking (100 days - 3539.1 kg, 200 days - 6727.5 kg of milk 305 days - 9602.9 kg of milk). Compared to the control group, where a 100 days lactation cows milked 3240.06 kg of milk 200 days produced 5433 kg to 305 of milk and 5327.18 kg of milk daily. The behavioral surveillance in both companies was carried out for 24 hours using the interval method with a 10 minutes interval period. The largest part of the day the cows were lying. The second largest dairy operations were the category of standing, which represented the average length of 6.05 hours in ZD Brloh. In the ŠZP Haklovy Dvory was the time period 5.71 hours. The significant period between groups is also the time of feeding, which in the system with the milking in milking house is much shorter by 1.79 hours and it taken 3.71 hours. The length of the movement was in the milking house more than half the size shorter and was 0.32 hours. Also, the length of staying in the milking house was about half shorter and it was 0.22 hours.

The main objective of this thesis was to evaluate various fertility indicators of dairy cows of Holstein cattle bred in modern farming techniques on the farm Rolnička Lipanovice and contribute to the clarification of interdependence of the factors, which influence fertility results. 288 inseminated breeding cows were included in to the reference group, in which it was possible to significantly demonstrate data collected by own observation or from the farm owner and inseminators. These data were collected since 1. 7. 2009 to 30. 6. 2010 and revealing information about rut course and intensity of observed breeding cows. The results that were concluded from recorded and processed data characterize the influence of various factors on fertility.

The diploma thesis was focused on the observation of various factors that are closely related to the number of somatic cells in milk of dairy cows. In particular, the season, the month, the order and stages of lactation and their relation to somatic cells, but also to the individual components of milk, were tested. The information was obtained from the performance and self-monitoring of Farmers farm for one year. As regards the influence of the season, the highest number of somatic cells was found in winter (537 thousand) and lowest in spring (365 thousand), but the difference was not statistically conclusive. The influence of the lactation sequence (min. 257,000 on the first lactation and max. 747,000 on the fifth lactation) and the lactation stage influence (min. 382,000 to 100 days of lactation and max. 557,000 over 401 days of lactation) was equally inconclusive ). A higher number of somatic cells in milk was associated with its lower production but higher protein content. The behavior of cows was substantially more balanced in the stable where the proportion of cows lying ranged from 60 % to 67 % than in grazing where it ranged from 3 % to 69 %.

The aim of this diploma thesis was based on analyze and following synthesis evaluated the effect of different types of bedding on milk performance parameters dairy cows of Holstein cattle. The experiment was carried out during one calendar year (February 2017 to January 2018). The monitoring was carried out once a month, one day after performance check in three selected farms – Company A (Farma Zdeňka), Company B (ZOD Lešná), Company C (ŠZP NJ). In the companies was used high bed with manure separation and ground limestone, a high bed covered with straw, deep bed with a sandwich of the first type with a layer of separating manure and ground limestone and deep bedding. Between milk performance parameters were included data of the order of lactation (n), days in milk (n), milk production (kg), content of fat (%), content of protein (%), number of somatic cells in thousands in 1 ml (PSB in thousands/ml). At the same time was determined the air temperature (° C). The results shows that the best type of housing cows was housing with deep bed with with a sandwich of the first type with a layer of separating manure and ground limestone according to number of somatic cells in the milk (145,6 thousand/ml) and the occurrence of mastitis (2,9%), as well as the milk production (36,9 kg) and the milk components content (3,9% fat and 3,4% proteins). The highest number of somatic cells (company B 419,3 thousand/ml and company C 378,9 thousand/ml) and the highest percentage of clinical mastitis (7,7% in company B and 5,7% in company C) were achieved dairy cows housing on high beds with a separation manure at companies B and C.

Abstract This diploma thesis aims to evaluate the natural breeding of cattle that excludes cattle bred for the market production of milk, and the birthing complicatedness in one specific company. The thesis includes short descriptions of the male and female cattle reproductive systems, the pregnancy cycle, and the birth. The most common complications during and after giving birth will be introduced along with a short summary of how to take care of the mother and the calf during the most critical period of their lives. This information is then applied to the circumstances in the chosen company where each birth was recorded with focus on its complicatedness, the size of the calf in relation to the size of the mother, and postnatal complications. The weight gain of selected calves was recorded during two separate weight checks while the data for cows include the age of their first calving and the period of time they have spent in the breeding cycle before the research.
