Prevalence of parasites of alimentary system in young cattle.
ŽIDKOVÁ, Marcela
In biennial following (spring 2005, autumn 2005, spring 2006, autumn 2006) we're rasitology examine 288 samples dropping from heifers and 288 samples dropping from bulls. Exhibits we're examined floatation in Sheather´s sugar solution. In examinate dropping we're proved present cysts Giardia intestinalis and oocysts Cryptosporidium andersoni and family Eimeria. In heifers was most frequent parasites coccidia Eimeria sp. (28,5 %). Flagellata Giardia intestinalis occur in 17 % of all designs. At least we're open up Cryptospordium andersoni (9,4 %). In bulls we're noted highest occurrence coccidia Eimeria sp. (19,1 %). Almost same occurrence we're found out near Giardia intestinalis (18,8 %). Very low prevalence we're have observed near Cryptosporidium andersoni (1,4 %).

EFFECT OF REARING HEIFERS GRAZING ON MILK YIELD AND FERTILITY
DVOŘÁKOVÁ, Lenka
The agricultural cooperative Opařany 160 pieces were selected for breeding cows anddivided into two groups. Pasture rearing and stable rearing. Which was observed fertility and milk yield. After an overall assessment of the breeding heifers, in 2007 the results of reproduction was worse in pasture system of heifer rearing. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing embody improved results than rearing in stables. After a general evaluation of milk yield, the grazing system of heifer rearing is worse in 2007. In particural the amount of milk in kg and kg of protein. By contrast, in the next reporting period in 2008 the grazing system of heifer rearing reachedimproved results compared stable rearing. And as the number of milked milk in kg, and milk ingredients - % fat, which is in pasture breeding higher in all of KU. The reason of low milk yield results and reproduction charakteristic is especially in poor nutrition and ill-prepared rations, or fed on poor quality components. In the grazing system of rearing the lack of growth in individual animals is due to missing supplementary feed. And for both groups, we should look for causes of poor management and the transfer of young animals to the reproduction and subsequent production should be taken into account the current condition, not age.

Noise mapping in livestock buildings for cattle.
MATĚJŮ, Aleš
The content of this work is to describe the structural characteristics of the objects and characteristics of production technologies. The main objective is to measure noise levels in selected buildings on their land borders. Measurements were stables for breeding heifers and calves. Furthermore, to ensure data from these measurements and their evaluation.

Fattening heifers on pasture
VALTER, Jiří
The main goal of this bachelor{\crq}s theses is to assess heifer fattening conducted in two grazing cycles in the mountain region of Southern Bohemia. The observation was carried out in the years 2008 and 2009. A total of 51 heifers was observed, all of them crossbreeds of Aberdeen Angus or Simmental cattle. In the first grazing cycle, the heifers were raised together with the mothers on a pasture and stabled for the winter season. The heifers were slaughtered after the end of the second grazing cycle, which followed the next year. Light weight of the heifers was recorded at the end of the first grazing cycle, at the end of the winter season and again at the end of the second grazing cycle. The weight of the dressed carcass and the SEUROP classification was further recorded. The average daily gain was calculated for each period from the live weight. The data set was sorted by the month of birth of the heifer and by the SEUROP classification. Statistical data analyses were carried out using the Excel software. In order to evaluate the results, basic statistical parameters were calculated for each of the selected variables and the cogency of the differences between the groups was tested with the two-tailed t-test at the corresponding level of significance. The average weight of the heifers at the end of the first grazing cycle was 266.0 kg, average weight at the end of the winter season was 349.8 kg and the average weight at the end of the second grazing cycle was 512.3 kg. The average age of the heifer at the end of the first grazing cycle was 216 days and they were slaughtered at the average age of 574 days. The average daily gain during the first grazing cycle was 1.14 kg, during the winter season 0.57 kg and during the second grazing cycle 0.78 kg. The lifetime average daily gain was 0.85 kg. The average weight of the dressed carcass was 247.1 kg. 60.8 % of the heifers gained the SEUROP class ``O`` and 39.2 % the class ``R`` or ``U``. The heifers showed considerable variability, especially in the weight at the end of the second grazing cycle (sx = 43.9 kg). Heifers gained the SEUROP class ``R`` or ``U`` showed higher weight at the end of both the first and second grazing cycle, higher weight of the dressed carcass and higher average daily gain during the winter season and during the second grazing cycle, compared with the heifers gained the SEUROP class ``O``.

Rearing heifers from the perspective of animal welfare
VOBINUŠKOVÁ, Zlata
The aim of this work was to assess and compare the conditions for rearing of heifers kept in two different houses to ensure the welfare of animals. Comparing is carried out in farms with breeding heifers Bohemian Spotted Cattle. By monitoring a group of heifers were included (hybrids Bohemian Spotted Cattle) of the nominated teams. Both groups counted 42 head of heifers. Monitoring took place in the open rearing stable Kámen and by stanchion rearing stable in Křeč. For behavioral monitoring was chosen method of direct observation of a group with an interval of length 10 minutes. Monitoring activities were: feed intake, standing, lying and moving. In addition to these basic activities were recorded and comfortable behavior agonist behavior and vocalization. In addition to the two houses were evaluated ethological monitoring and other parameters, such as reproductive performance, herd management, the very construction, technology, housing, bioclimatic in buildings, in a stable operating mode, etc.
