The influence of pasture on biodiversity of invertebrates in sub-mountain localities - coprophagous beetles
SVOBODA, Lukáš
The effect of the pasture management on dung beetle communities was studied on three sites in Šumava Mts. (South and West Bohemia). The intensity of pasturing was different: 78 cattle on the first, 106 on the second and 162 on the third pasture. The beetles were collected using pitfall traps baited by 1.5 litres of fresh cattle dung. The traps were located on each pasture. Altogether 3 traps were used per each pasture. The pitfall traps were exposed in the pasture for 7 days in monthly repetitions from April to October 2008. Totally 8725 specimen and 33 species of beetles were collected. These species belong to families Scarabaeidae,Geotrupidae and Hydrophilidae. The number of species and individuals was evaluated for each pasture, as well as seasonal dynamics and biomass distribution. The results indicate that the more intensive pasturing has the positive effect on the activity of some groups of coprophagous beetles.Other effects of the different pasture management on the beetles were not documented.

Influence of breeding technology on the utility characteristics of the dairy cows
TRCH, Jan
The aim of this bachelor thesis was to evaluate fertility and milk performance due to technology used in new dairy cow housing. Monitoring was carried out between 2008 and 2009 in the farm Agrospol, which is situated in Malý Bor. All cows were kept in the same technological conditions. Monitoring was carrieed out in 110 dairy cows of Czech spotted (C), Holstein (R) and crossbreeds of these cows (CxR).There were measured indicators of fertility (insemination interval, service period, interim and age at first calving) and indicators of milk production (lactation length, milk quantity, fat content, protein and lactose content).There was found a statistically significant difference in the length of insemination interval in the reproductive indicators. Cows "C" had the lowest numbers in all reproductive indicators: insemination of 72 days, service period 101 days, 386 days of interim and age at first calving 779 days (25/19). Holstein cows reached a length of service period of 133 days which is about 32 days higher than the value of dairy cows "C". Holstein dairy cows in lactation produced at average 9913.6 kg of the milk, cows "CxR" 9839.3 kg and Czech spotted cows 9142.3 kg. There was not found statistically significant difference between these values. The best results in milk production per standard lactation reached cows "C" (9528.7 kg) in the second lactation, cows "CxR" (9751.9 kg) as same as cows "R" (10 695 kg) in the third and following lactations. The highest average fat content of dairy cows had "CxR" with a value of 4.71 %; the fat content was 4.61 % by "R" cows and 4.56 % by "C" cows. There was not found a significant difference at average protein content of dairy cows. Cows "C" reached 3.36 %, cows "CxR" 3.38% and cows "R" 3.35 % of the protein.

Analysis of commercial properties in dairy herds.
POTUŽÁKOVÁ, Jitka
The aim of the thesis was to evaluate fertility and milk performance in dairy cows, predominantly Holstein cattle, due to technology used in the view of welfare animals. Monitoring was carried out on the farm AGROSPOL, Malý Bor a.s. from 2008 to 2010. Dairy cows were kept in the same technological conditions, with the same level of nutrition and treatment. Monitoring included 662 dairy cows of Bohemian Spotted Cattle (C), Holstein cattle (H1) and high proportion of crossbreeds of these cows (H2). Fertility was evaluated due to indicators of reproduction (first calving age, insemination interval, service period, interim) and in terms of milk performance there were measured indicators of milk production (lactation length, milk production, protein production, fat content, protein and lactose content). Statistically, significant differences were found in the length of insemination interval, service period length (P ? 0,01) and interim length (P ? 0,05). Dairy cows (C) reached markedly shorter period of the following indicators: insemination interval 70,6 days, service period 98,6 days and interim 395,9 days. There was not found a significant difference in length of these indicators among the groups of Holstein dairy cows. Lactation order did not influence the length of reproduction indicators. The influence of bull-father in terms of reproductive indicators was not proved. Comparison of milk production and protein production in dairy cows due to lactation order proved that cows in the first lactation had a lower yield of milk (8737,1 kg) than dairy cows in the following lactations (9669,3 ? 10209,3 kg), as well as protein production (kg). Dairy cows ?C? gave 9115,3 kg of milk in 305 days, dairy cows ?H1? 9664,1 kg and cows ?H2? 9511,0 kg of milk. These differences were not evaluated as statistically conclusive, as well as differences in content of milk elements among genotypes in fixed lactation norms. The influence of the individuality of a bull in milk and protein production was not proved. Significant differences were found in percentage of fat content (P ? 0,05), protein and lactose content (P ? 0,01) in milk of cow-daughters after particular bulls.

Breeding Results of Bohemian Red Cattle in South Bohemia Region
VAŇKOVÁ, Kateřina
This work is focused on the evaluation of breeding Czech red cattle breeders working South Bohemian Region, guaranteed of the Faculty of Agriculture, University of South Bohemia in České Budějovice. This work describes the characteristics of the breed, its origin and the process of regeneration. The ongoing process began with the absorptive crossing of Czech Pied cattle with Czech red bulls, which led to the increase of female part of population over the number corresponding with the size of critically endangered breed. The situation in male part of population is less favourable with critical lack of bulls, which slows down the regeneration process. According to the exquisite assumption of meat production, but with worse results of milk efficiency, the breeding of cows without market milk production seems to be the best way. It is very important to keep of safe boundary of koeficient intensity of family breeding at potential descendants. Not even providing this process to be successful, the breeders Czech red cattle won{\crq}t get along without adequate subsidies, which should be offer to partial animals with verified genotype according to their category. Currently is the number of animals with genotype CC, which fall under the control of appointed department, 114 pcs.

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.

Evaluation of observed parameters of a beef herd.
CIMBURKOVÁ, Pavla
It has been observed beef breed herd of Aberdeen Angus cattle in the foothills area of Novohradské mountains in 1992 - 2007. The base of herd was consisted of 117 dams and 814 pieces of calves in total. The parameters of beef production of calves and the reproduction of dams were monitored. For the parameters of growth of calves were found significant effects of the year, the month of birth, sex, the order of calving, the method of reproduction and the sire.
