Influence of probiotic feed supplements on the growth and health calves
ŠEBKOVÁ, Anna
Thesis contains informations about right stabling and nutrition of calfs. It´s include importance of probiotic supplements and their influence to growth and health of cows. Newborns weight in seven days after birth was similar (54 kg) in every of three groups. Significant diferences were registered at the end of these monitoring, in ninety days after birth. First Group witch consumed RumiForm Digest had average wight 126 kg. Groups witch consumed RumiForm Digest with bacteria mixture, had average weight 146 kg. In every monitored groups diarrheal was detected. The biggest frequency was detected at group, witch consumed RumiForm Digest with bacteria mixture. There was detected 9% diarrheal diseases in total 48 calfs. Deads were detected only in the group of calfs whitche eat RumiForm Digest with probiotics during the experiment. Total mortality was less thas 2%. There wasn´t shown influence of probiotics to calfs growth (p-value (calves weight on the 7th day after birth) = 0,63; p-value (calves weight on the 90th day after birth) = 0,31, p-value greater than 0,5), either to calfs health (p-value (comparison of diarrhea rates) = 0,67; p-value (death) = 0,82, p-value greater than 0,5). Can not be said, that the eating of probiotics supplements had pozitive influence to calfs grow and health.

Ekonomické zhodnocení výživy telat do odstavu
NEJDROVÁ, Eliška
The bachelor's thesis deals with the nutrition of calves until weaning and later the overall economic evaluation of both nutrition and breeding. The nutrition of calves is very important for the future benefits for the health of the calf and its subsequent utility in cattle breeding. For us, the nutrition of every living individual means certain investments. In this case, it is important to evaluate the investment correctly. There should be no shortage of resources for proper nutrition. The bachelor's thesis contains information on the individual nutritional periods of calves, namely colostrum, dairy and plant. It describes the recommended parameters that must be observed in nutrition and feeding technology. The work also deals with the technology of breeding and an overview of serious diseases of calves. Subsequently, the economic evaluation of calf breeding is described here. The bachelor's thesis evaluates the economic side of calf breeding. The company was characterized and the breeding of weaned calves was evaluated from an economic point of view. The final chapter points out several possible solutions to improve the nutrition of calves.

Výživa telat do odstavu, rizika spojené s dietetickými poruchami
ŠIMKOVÁ, Františka
The bachelor's thesis includes the physiology of the digestive tract in cattle and deals with the nutrition of weaned calves. This topic includes colostrum nutrition in the first days of life after the birth of a calf. It is the most important period in nutrition in general, because it affects the production of passive immunity of calves and thus future performance. The next stage is nutrition with milk or milk compound feed. The later performance associated with the proper development of the rumen is also affected by the administration of the starter during the dairy period. The next chapters summarize calf diseases associated with dietary deficiencies, which are mainly diarrheal diseases. The final chapters suggest the treatment and prevention of these diseases.

Gut parasites of sheltered calves
HORSKÁ, Ivana
On a chosen farm were during year 2008 obtained for parasitological examination faecal samples from the rectum of calves. A total of 71 faecal samples from 70 calves was collected and examined by Sheather´s floatation. Thirty-three of the faecal samples were positive on parazites, Cryptosporidium sp. and Eimeria sp. oocysts weres found in the positive samples. Most often diagnosed parasite was Cryptosporidium sp. that was most prevalent in calves 1 {--} 2 weeks old. The infection by Eimeria sp. was highest from the 4th to the 5th week of the calves age. Parazites were mostly prevalent in weak and medium diarrhoea and were rarer in stiff feacal samples. 51,4 % of female´s faecal samples were positive on parazites and 41,7 % of male´s faecal samples were positive on parazites.

Gut parasites of calves kept outdoor
HRDLIČKOVÁ, Jaroslava
During the year 2008, at irregular intervals, we collected samples of faeces directly from calves' rectum for parasite examination. A total of 57 samples from 48 calves was examined. We examined the samples by flotation- cetrifugation according to Sheather. In positive samples, we found oocyst of Eimeria sp. that were most common in 7 {--} 9 weeks old calves, and oocyst of Cryptosporidium sp., which were found in younger and older calves. In solid faeces, weak, medium and strong diarrhoea we found Eimeria sp., in solid faeces and weak diarrhoea we foung Cryptosporidium sp. The intensity of infection was usually weak. It results by comparison than general parasite prevalence was in the same period (except winter period) lower in individual boxes than in shedded calves.

Vliv teploty vzduchu na chování telat českého strakatého plemene skotu ve venkovních individuálních boxech
Krejčí, Hana
The aim of bachelors thesis was to evaluate the effect of ambient temperature on the behaviour of calves of the Czech paternal breed of cattle in their outside individual boxes. Besides air temperature, the sex and season of birth of the calf were taken into account.The behaviour, which was recorded, concerned standing and lying of the calf both in and out of the box. The entire observation was conducted on an agricultural holding near Nové Město na Moravě. Observation was carried out once every month, in the period from November 2015 to October 2016. The acquired data was displayed in 5 tables and 10 charts, which correspond to the given issue. According to the results obtained, it is evident, that the increase in ambient temperature has little effect on both male and female calves. Calves are lying and situated in these outside individual boxes mostly from the time of birth until the 15th day of age. The calves dwell in boxes mostly in the fall.

Výživa telat do odstavu v návaznosti na technologii ustájení
ČENĚK, Tomáš
The Bachelor work deals calf nutrition to weaning in housing technology. The total development and health of calves influence of various factors, not only prenatal, but also in the postnatal period. However with successful weaning of calves We achieve basic of cattle breeding. Everything is dependent on maintenance, which is great for good health and production of calves parametres. For great economics of breed is very important to ensure relationship of stabling technology, which is the main aim of calves breeding. At the bachelor work is assessed the concept of calf nutrition a their housing and other parametres affected their health and general welfare of animal. At the first part of my work desribe the generally calf nutrition. After that especially colostrum period which is the best priority for great herd and milk period which is important as well to the weaning. At the second part the work describe housing technology of calves periods which is great for every breed. Here is too introducing chapter of the worst mistakes which we can see at the companies. The Bachelor work desribed concepts of calf nutrition at the agricultural company and their requirements for housing technology. This priority are very important for agricultural company and others subjects of farm production. At the end of my work recommended some resolutions of calves nutrition.
