Changes of the meat quality meat characteristics during storage
ZIEGLBAUEROVÁ, Karolína
The bachelor thesis is focused on the evaluation of quality characteristics of beef during its storage. The literature review defines the term beef, the consumption of beef in the Czech Republic, describes its chemical composition and properties. In this work The paper evaluates the factors that affect the quality of beef and their distribution. It is further characterized by the maturation of meat, then its storage. The practical part is focused on the measurement of basic analytical components in the muscle of cattle, originating from their own breeding and from a farm with comparable breeding conditions. The aim of this bachelor thesis was to compare the properties of meat of three breeds of cattle, especially to determine the changes in the basic analytical values of meat during its long-term storage. The amount of water, protein, fat and collagen was monitored using a NIRMaster instrument and the results were then compared.

Vlivy působící na behaviorální projevy krav plemene highland na pastvě ve vybraném chovu
Pálková, Michaela
This bachelor thesis deals with the effects that affect the behaviour of highland cows on pasture. Observations were made on an organic farm in Lípa u Zlína, which is situated in Zlín region in the area od Lípa nad Dřevnicí, in summer and winter 2015. The observed behaviour of cattle was: standing, physical aktivity, food and water intake and lying focused on laterality of individuals. By this monitoring, evaluation and subsequent graphical statistical methods was found a slight effect of the season on the symptoms above, the mahor diference was between standing and lying. On averadge, the animals spent most of their time by food intake, lying, standing less by physical activity and water intake.

American foulbrood and its occurrence in Highland
MORBICEROVÁ, Iveta
The work deals with foulbrood disease, pestilence foulbrood. It's one of the most dangerous diseases that can affect the colony. This disease caused by bacteria of the genus Bacillus - Bacillus larvae. Further, there are shown clinical symptoms, diagnosis, spread of disease, how to fight the disease and scream it can be prevented. In prektické was described by the occurrence of plague in the Highlands, which had an impact on beekeepers and how to deal with the problem of the state of health authorities. The annex contains tables showing the list of outbreaks and the destruction of bee material. Furthermore, the figures showing pictures on this topic.

Evaluation of selected influences on performance of beef cattle
ZÍDKOVÁ, Jana
The aim of this Bachelor thesis was to compare meat breed cattle efficiency. For the comparison were chosen these breeds: Aberdeen Angus and Highland. Data about the breeds were finding on Branišov ecofarm and on Bořanovice ecofarm in the area of Šumava national park. Highland cattle breed - Scottish national cattle was imported to Czech Republic in 1991 from Scotland to mountain conditions of NP Šumava to Branišov farm. This breed is ranked among extensive meat breed of small constitutional type, it is also called ?hobby breed?. Aberdeen angus breed is ranked among most widespread meat breed in the world. It originates from North-East Scotland, where the meat performance cattle type was bred in early 18th century. Later it was crossbred with shorthorn breed. Aberdeen Angus is a breed of genetically hornless minor to medium body frame. At breeds the growth was valued by detection their live weight at birth, at the age of 120, 210 and 365 days. From detected data of suspense files basic statistic characteristics were evaluated (percent occurrence, arithmetic mean, minimum, maximum, standard deviation). The average weight of HI breed calves at birth was 25 kg at bullocks and 20 kg at heifers. In 365 days the average weight of bullocks reached 301 kg and 264 kg at heifers. The average weight of AA breed calves at birth was 37 kg (bullocks) and 34 kg (heifers). In 365 days the average weight of bullocks reached 485 kg and 365 kg at heifers. Further there were ranking of reproductive indices and maternal qualities of cows. From observed results was evaluated father influence, birth sequence and calve month sequence depending on calves? weight. Father influence on calves? growth at AA breed wasn?t statistically significant. The highest live weight in 120, 210 and 365 days had AA calves at third calving. At HI breed was influence of calving sequence on claves live weight statistically insignificant. The highest live weight (120, 210 days) had the calves born in august at AA breed (175, 64 kg or 275, 27 kg) and at HI breed (at the age of 210 days 183, 33 kg). In term of economics is this stock raising without grants unprofitable. With grants the gain on VDJ amounts 6876 CZK at AA breed and 10 186 CZK at HI breed. The results proved, that for provision of profitable stock raising BTMP would the Aberdeen Angus heifers be calved at first at the age of 24 months, it has to be assured good fertility of cows, high additions of calves and also high longevity of cows.
