Význam vitaminů a minerálních látek ve výživě býků plemene masný simentál
DVOŘÁKOVÁ, Markéta
My bachelor thesis deals with the significance of vitamins and minerals, which belong to the food additives. Additives are very important for the proper functioning of the organism. A lack of these substances in the nutrition worsens the overall health and causes metabolic disorders. It is necessary to maintain sufficient additives and the right proportion of minerals in nutrition. In the first part I describe the morphology of the digestive systém of cattle and the function of its individual parts. In the second part I characterize beef cattle and their fattening. In the last part I deal with the nutrition of beef cattle, the division of vitamins into fat soluble and water soluble. I describe individual minerals, which are divided into macroelements, microelements and trace elements. In conclusion, I present my opinion on the importance of additives in the nutrition of beef cattle.

Trmalová, Kamila
This thesis deals with rules and principles of reproduction in cattle rearing suckler. Contains information from the biological basis of the reproduction which is needed for biotechnological methods into practice, through the selection and assessment of sire to herd organization and welfare of breeding animals. The breeding of beef cattle in practice prefers natural animal breeding while in herds of dairy cattle is often used method of artificial insemination. Another part is devoted to ecological agriculture in which especially prevails the system of sucklers. The thesis presents an evaluation of the reproductive results of beef cattle based on the results of performance contol. In conclusion are highlihted the main differences on conventional animal agriculture and organic farming.

Rozdíl v tržní produkci mezi dojeným a masným plemenem skotu
Pešová, Nikola
The thesis Difference between business production of dairy cattle and beef cattle breed is focused on quantification the differences between dairy and beef cattle breed. Main objects of observation were differences in the number of born and dead calves, the differences in negative selection of cows, average states of heifers during one year, average number of fattening bulls and young bulls destined to fattening , and also differences between revenues of milk and sold animals. This information was gathered on two farms with cattle production, one is dairy farm on South-Moravia region and another with beef cattle is in Moravian-Silesian region. All was observed in year 2016. The results of this thesis were that difference of all business production between dairy farm × beef cattle farm could be until 53 036,5 Kč/cow/year for dairy cow farm. Dairy cattle farm earned almost 30 799 824 Kč for year, with no subsidy. The 77,8 % of revenues was formed by milk and 22,2 % was formed by slaughter animals. The beef cattle farm earned 2 509 888 Kč for year 2016, with no subsidy. Difference between the number of born and dead calves was almost identical. Approximate natality in dairy farm was 91,2 %, in beef farm was 95,5 %. The number of dead calves was in both farms same, 10 %. About negative selection of cows, there was bigger selection in dairy farm (20.51 %), than on beef farm, where was lower selection (8,15 %). In average states of heifers in category from 6 months to 1 year the states were different in seasons, when in June and July there were no heifers in beef farm. The states in category of 1 year to 2 years were judged as a contradictory, because in months where on dairy farm states grew up, the states on beef farm falls. The category of heifers in 2 years and older was the most same and the lower state were in both on the beginning of the year and higher on the end of the year. About the fattening bulls, in both farms were different production (fattening × production of young bulls and heifers). The dairy farm has earned for fattening bulls all year long. The September was the month where the both farms sell the most animals. In this month the beef farm sold all young animals. The exception was two breed bulls sold in the half of the year.

Faktory ovlivňující životaschopnost a růst telat masného skotu
Hlaváčková, Marta
The literature review describes factors affecting the viability and growth of beef cattle calves. The aim of the literature review was to summarize information of various authors and to elaborate an overview of factors such as maternal nutrition, its health status, the course of calving or nutrition of cattle calves. The thesis also contains my personal practical information and experience in the care of little vital calves that I have gained during my life on the farm. The practical part considers the analysis based on the causes of the reduced viability of calves in our cattle farming. By measuring and weighing I evaluated the influence of various factors on growth ability. Three calves with reduced viability are compared (healthy calf of sick mother, sick calf of healthy mother, sick calf of sick mother) with a control calf (healthy calf of healthy mother). In the final part of the thesis the results obtained are appraised.

Zhodnocení přirozené plemenitby ve stádě krav bez tržní produkce mléka Agrofarmy Dubnice s.r.o.
Šrubařová, Markéta
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.

Vliv délky odchovu zástavových býčků na ekonomickou efektivnost jejich produkce
Olišarová, Martina
The aim of the thesis was to evaluate the economic efficiency of breeding bulls in relation to the length of rearing. Measurements were made at three breeders´, where five turns were counted. The conclusion of the thesis is focused on the comparison and evaluation of bull breeders and their economic efficiency. From the results of the work was found out that with the rising breeding length and growth increment, the calculated difference between sales and costs is reduced. For all breeders surveyed, the overall increase is increasing with increasing number of feedbeds. The relationship between the increase and the consumption of fodder has been found to be such that increasing consumption of fodder feeds is also increasing. On the basis of the findings it can be stated that the breeding length of the breed had a great impact on their economic efficiency as their efficiency decreases with the increase in the length of the retracement.

Vybrané vlivy na růst telat masného skotu
TOMKOVÁ, Michaela
The aim of this work was to analyze selected effects on the growth of calves of a selected herd of aberdeen angus cattle in Mýto farm in Hořice na Šumavě for the monitored period of 6 years (2012 - 2017). A total of 242 pure-bred calves of the aberdeen angus breed born during the reference period was included in the evaluation. Birth weight, weight at 120, 210 and 365 days were determined in calves. Subsequently, the group of calves was sorted by sex, year of birth, month of birth, birth order, father's individuality and mother's exterior. The data were statistically processed in Microsoft Excel and evaluated in Statsoft Statistica. When confronted with the national average published in the KUMP deadlines, the observed calves always had a lower birth weight, but higher weight at 120, 210 and 365 days. When evaluating the effect of the year of birth on calf growth, it was found that calves born in 2012 and 2013 achieved the best results. The best months for calving aberdeen angus breeds on the monitored breed were February to April. In terms of birth order, calves born to cows after the third calving achieved the best results. The worst results were achieved by calves from heifers and cows after the ninth calving. The best breeding-bull in breed regarding to the growth ability of calves was the sire ZAA 916. The PAA 027 sire showed the best results in terms of ease of delivery. There was no significant difference in the effect of maternal exterior on the growth ability of calves.
