Hodnocení růstu a jatečné hodnoty skotu
Morávek, Marek
This bachelor thesis deals with the growth of cattle, its carcass value and technological systems used in fattening categories. First, the characteristics of growth, ontogenesis and the associated stages of growth, the methods used to evaluate growth, and what affects growth are described. Then the work is focused on meat production, where the terms associated with it are characterized, namely the carcass value with fattening. Furthermore, the effects that affect performance. The bachelor thesis describes individual slaughter categories and the part is devoted to technological systems of fattening of individual categories. The bachelor thesis evaluates the slaughter of cattle in the Czech Republic and their performance. The defeats of neighboring states are also evaluated and the information found is compared with the Czech Republic.

Analýza masné užitkovosti u plemene Český strakáč
KLEČÁKOVÁ, Martina
The aim of the bachelor thesis was to compare the meat performance in rabbits of the Czech piebald breed kept in different types of housing. One group of rabbits was kept outdoors in the huts with a range and the other in a classic covered hutch. A total of 38 rabbits were monitored, 19 of them outdoors and 19 in the hutch. There was no difference in the length of fattening between the rabbits in the hutch and the outdoor (141.47 or 142.32 days) and in the live weight before slaughter (2.62 kg or 2.61 kg). On the other hand, the difference was very significant in other indicators, e.g. between the weight of the carcass, where the rabbits outside had lower weight (1.70 kg) than rabbits in the huts (1.78 kg). The results were more favourable for rabbits reared in hutch. When monitoring the meat performance indicators by sex, a very significant difference (P 0.001) was found only for the length of fattening. The fattening time for males was shorter (140.05 days) than for females (144.06 days). It was also insignificant for live weight. Other indicators were more favourable for males.

Záchrana a regenerace plemene skotu české červinky
VACEK, Tomáš
The aim of the thesis was to create a clear literary study on saving the breed of the Czech Red cattle with the balance of the results achieved during the regeneration process. Work includes the regeneration process, related breeds, state aid, studbook, breeding bulls, numerous states, the number of farms with breeding conditions and the appreciation of the exterior. Within its processing, milk yield from database (123 lactations of 35 cows) was evaluated and compared with the breeding goal and literature. Fertility age at first calving (32 times) and interim (91 times) from the monitored cows were also evaluated. These data were then compared with the Polish Red Cattle. Meat performance was evaluated in relation to the growth of three breeders (113 individuals) and compared with the breeding goal and literature. Development of weight of cows and bulls from the 17th century to the early 21st century was also compiled from literature, and then compared with the Polish Red Cattle and Angler Cattle.The study suggests that state support has mostly declined during the years 1997 2015. Populations of the Czech Red cattle (198 individuals in 2015) and number of farms (30 pieces in 2015) have predominantly increased. Milk yield (2550 4409 kg, 4.18 to 4.30% fat and 3.46 to 3.50% protein) generally met the breeding goal. Age of first calving (30.5 months) and the interim period (439 days) lagged behind the Polish Red breeds. The meat production in heifers in one hundred days (110 kg) and at 365 days (267 kg) just met the breeding goal. In the case of the average daily gain increase (0.641 to 0.888 kg / day), the breeding goal has not been met. Bulls in one hundred days (130 kg) crossed the breeding goal, as well as for the average daily gain (1.001 to 1.055 kg / day). A comparison of the development of the weight of cows and bulls suggests that Czech Red cattle held approximately the same weight from the beginning of the 20th century (488 kg in the 21st century).

Produkční schopnost býků Českého strakatého skotu
LAPKOVÁ, Kristýna
The aim of this bachelor thesis was to evaluate selected indicators of fattened bulls of the Czech Pied Cattle in intensive farming conditions in a farm in the South Bohemian Region. The total rating was included 371 bulls, the data were evaluated for years 2016 and 2017. The live weight before slaughter, the age at slaughter, the average daily gain, net gain, carcase weight and his classification according to SEUROP. Statistical data was processed using the program Microsoft Excel 2016 and Statsoft statistica. The average age at slaughter and live weight were 586.2 days respectively 731.8 kg in 2016, in 2017 reached 626.1 days respectively. 749.5 kg. The weight of the carcase in 2016 was 412.2 kg, the following year increased by 8.9 kg. The net gain increase was significantly higher in 2016. All these differences were statistically significant. When categorized into classes of meatiness, it reached 73.8 % of the class "U" with a carcase weight of 426.3 kg, 25.1 % of the "R" class with a carcass weight of 384.4 kg and 1.1 % of the "E" with a carcass weight of 497.3 kg. When evaluating the impact of the slaughter age on the individual indicators, the differences between the groups were statistically significant.

Vyhodnocení masné užitkovosti králíků v drobnochovu
BOUCHALOVÁ, Kristýna
This bachelor thesis deals with the meat production of rabbits in home breeding in large breeds, the Checkered Giant rabbit and Flemish Giant rabbit. For comparison, the middle breed of the California rabbit was used. Small breeders are predominantly medium-sized rabbits for their very good cattle yield and short-term fattening. The most important thing for fattening is to achieve mature maturity in the shortest possible time. In our experiment, the Californian rabbit fattening took 149 days and the average slaughter weight was 3144g. In Checkered Giant rabbit took 171 days and for the Flemish Giant rabbit for 184 days. The average slaughter weight for the Checkered Giant rabbit was 4566g and for the Flemish Giant rabbit 4744g. The lowest slaughter yield of 48.6% in our experiment was achieved by females of Checkered Giant rabbit and the highest 56.7% male California rabbit.

Analýza ekologické farmy s chovem zvířat
Martyninková, Dajana
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.

Vlivy působící na masnou užitkovost ovcí
MALÍK, Dominik
The Thesis The factors affecting sheep meat yield is concentrating on lamb growth ability and the factors which can positively or negatively affect this ability. The basic findings of previous researches and analyses are mentioned at the beginning of the thesis followed by basic classification of lamb meat yield factors. Subsequently, there is an explanation of author's own research where the selected factors were empirically tested. The research took place between years 2013 and 2016 on one flock of sheep on pastures of Orlicke hory region. The birth weight and the weight gain of lambs were monitored in order to evaluate effects of gender, feeding rations and number of lambs in one litter on weight gain ability of each reared lamb. The research has shown that the most important factor is the correct setting of feeding rations while the initial birth weight is mostly influenced by the number of lambs in one litter. On the other hand, the research was unable to prove the effect of gender on the weight gain.

Vliv sylimarinu na jatečnou výtěžnost králíků
KREJČÍKOVÁ, Klára
The work deals with the influence of the Milk thistle (used substance Silymarin) on the carcass yield of hybrid combinations rabbits Hyla. Hybrid combination Hyla was purposefully bred for meat performance, showing excellent results in breeding. Rabbits behave primarily on meat, because nutritional properties correspond to the current requirements of rational nutrition. Therefore, it is appropriate to increase the carcass yield. The average slaughter yield is indicated from 40 to 53% according to the breed. It was found that the addition of milk thistle in the form of a powder in the complete feedingstuff at a concentration of 0.2% increased the carcass yield, relative to the control group (which was fed only KKS), on average by 0.4%. The group with the addition of 1% showed an average value of 1.2% higher than the group control. The average slaughter yield of all the groups ranged from 54,68 into 63,02%. In both farms also decreased the incidence of diarrheal disease. Silymarin has a favorable effect on the operation and growth of the liver. In the group with the addition of 0.2% increased the average liver weight of 8.1 g, in the group with a concentration of 1% weight on average picked up about 10g. The average weight of the liver varied from 111,19 to 121,20 g. The control group in the case of carcass yield and liver weight showed better results than the authors of their articles.

Relations between production capabilities and economy of Charolais cattle breeding on selected farm
Rozsévač, Ondřej ; Stádník, Luděk (advisor) ; Zuzana, Zuzana (referee)
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.
