The influence of beef cattle pasture on composition plantation form and developmen non-producing functions of grassland
TRNKOVÁ, Ivana
The influence of beef cattle pasture on the composition of pasture herbage was studied in Šumava region (Kaplice, 550 {--} 850 m a.s.l) from 2005 to 2006. Also was studied the effect of different nanagement of permanent grassland on its composition plantation form and non-producing functions. On the pasture herbage dominated grass and leguminous species. On the fallow land prevailed herb species. On the combined management site (pasture and harvest) was established higher frequency of Taraxacum officinale, Trifolium pratense and Dactylis glomerata

Comparison of gut parasites incidence on chosen farms
HUBENÁ, Lucie
The main goal of the thesis was to compare prevalence of intestinal parasites of cattle in farms using different technologies of breeding, and evaluation of the obtained data. Irregularly, from spring to autumn 2010, faeces samples of dairy and meat cattle were collected from the chosen farms. A total of 425 samples of cows from three farms was collected. Two of the three breeds (herd A and B) consisted of Holstein and Fleckvieh Breed, first of the herds was pastured. The third herd (C) was of Limousine breed and was pastured whole season. The samples were collected in plastic containers in fresh state. In the examined samples, gut parasites of genus Eimeria and helminthes of the family Trichostrongylidae were diagnosed. In the herd A, no intestinal parasites were found. The most common parasites diagnosed in the herd B were coccidia (38%). Helminths of family Trichostrongylidae were also diagnosed (16,6%). In the herd C, both coccidia of the genus Eimeria and parasitic helminths were found (thirs prevalence was 38% and 26%, respectively). Seasonal dynamics of the parasites was also monitored, a descending trend was detected from summer to autumn. Prevalence in the herd B was 64% in summer, 58% in autumn, in the herd C were the respective prevalences 66% and 70%.

Monitoring moving activity of beef cattle during the year
RUDA, Jan
Beef cattle breeding is one of the basic and traditional kind of agriculture department in the Czech Republic. In the last few years is growing the number of beef cattle especialy in mountain areas and foothills. My work was focused on assesment of moving activity of beef cattle (whole year outdoor lairage) with special aim at outward and inward factors. Experiment was realized in a small privat farm (40ha) in foothills. Breeding animals are crossbreeds of these beef cattle races: charolais, piemontese, aberdeen angus, hereford, gasconne, limusine and czech pied cows. Monitoring was made by pedometers placed on the neck part and anterior limb (used 20 animals) and on the neck only (used 10 animals). Pedometr counts the numer of movements in hour, every single hour is separated into 240 parts - 15 seconds each. If is there any move during that time, pedometr will record. The additional technical equipment is antenna and PC with an appropriate software. For temperature and air humidity measuring was used datalogger noticing the data every hour. We compared the influences of tempereture and air humidity on moving activity, influence of rutting season on moving activity and finaly the differences between the data from the neck part and from the anterior limb. Was found out that the temperature has a fundamental influence on the moving activity. No ralation between the air moisture and the moving activity was found. There was not such a big increase of moving activity during the rutting season as we expected. The activity measured on the neck was significantly higher then the activity measured on the anterior limb. Both of them embodied mathematical functional dependence.

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.

Evaluation of sire rearing results of beef cattle breeds
STRNADOVÁ, Eva
During the work, results of ten sires of beef breeds had been observed in OPB Cunkov s.r.o. Over the years 2004 to 2007, 590 pieces of animals was evaluated. The highest number of all the evaluated sires was at the breed charolais (211 pieces), with average daily gain of 1883 grams, which was the highest daily gain from all the breeds evaluated. Of all the number of bulls included, 81,7% of them was included in breeding process and 18,3% of them was negative selected. Rearing house is an important means the other progress of beef cattle breeding.

Breeder and economic evaluation of beef cattle rearing
ZRŮBKOVÁ, Ludmila
This dissertation deals with the issue of breeding and economic evaluation of beef cattle within the company 'Zemědělské družstvo Krásná Hora nad Vltavou a.s.' between 2009 and 2010. The goal of this work is to evaluate the breeding standard of Blonde d' Aquitaine livestock breed in the above-mentioned company's breeding barns in Vysoký Chlumec, Obděnice, Skrýšov, Hojšín and Narysov. The results show that the profitability of beef cattle breeding is possible only on condition of subsidies and significant wages and overhead costs lowering.

Analysis of beef cattle breed
KOLOUŠKOVÁ, Martina
The purpose of this thesis was to analyze the efficiency and fertility of beef cattle herd kept without market milk production on a farm Ostrý u Jistebnice, owned by ing. Pavel Kozák. Monitoring of the herd took place in the period between the year 2006 and 2008. The objects of analysis were 149 purebred cows and 296 calves of Belgian Blue, Blonde d{\crq}Aquitaine, Charolais, Limousin and Simmental breeds.At cows, age during first calving, time interval between calving, number of birth and occurance of complicated birth have been recorded.The weight of calves at birth, in the age of 120, 210 and 365 days, has been checked and average daily increments have been counted.

Beef cattle breeding in the marginal regions of the Southern and the Western Bohemia
KYNKALOVÁ, Pavlína
The aim of this diploma work was to evaluate the level of beef utility at particular breeds. The breeds were bred in different climatic conditions of foothills and mountain regions of the Southern and the Western Bohemia. It was observed the use of permanent green grass by beef cattle´s pasture in relation of reached utility. There were included in total 31 farms in monitoring. The farms keep 7 breeds (Aberdeen Angus, Galloway, Hereford, Highland, Charolais, Simentál and Salers). There were 16 farms situated in regions under 600 meters above sea-level and 15 farms in regions over 600 meters above sea-level. The data were collected during 5 years. At cows, month of calving and occurrance of complicated births, have been recorded. The weight of calves at birth, in the age of 120, 210 and in certain cases also 365 days, has been checked. There were counted the average daily gains to mentioned weights. The group has been sorted according to breeds, elevation above sea-level and sex of the calves.

Analysis of chosen effects on the efficiency of beef breeds
ZATLOUKAL, Jan
The aim of this dissertation lies in analysing the calf growth of a selected herd of meat-type cattle raised in a foothills landscape. The period of investigation lasted 5 years (2002 {--} 2006). The data obtained for the breeds Charolais and the meat-type Siemental cattle are presented in dependence on the breed, convenience of birth, mother´s height in the cross, calving month and the serial number of the birth. The study covers 795 Charolais calves and 450 calves of meat-type Siemental breed. In the time interval mentioned above, the Charolais breed gave 400 bulls and 395 heifers, the corresponding numbers for the meat-type Siemental breed are 226 bulls and 224 heifers. Considered from the viewpoint of breed influence on to the calf rate of growth, the investigation has revealed no statistically significant effect. A statistically significant effect has been revealed only for heifers 120 days old, the live weight of the meat-type Siemental heifers being higher (162,71 kg) than that for the Charolais heifers (158,14 kg). The differences in the live weight amount to 4,47 kg. Statistically, this diference is probably significant, the significance level p = 0,05. Furthermore, the work has studied the effect of calf sex onto the rate of growth in both calf categories mentioned above. The live weight of the meat-type calves show a statistically highly significant difference (p {>} 0,001) for the bulls and heifers at the age of 120, 210 and 365 days. At the age of 120 days, the live weight of bulls is by 14,31 kg higher compared with that of heifers, at the age of 210 days the difference amounts to 25,65 kg and at 365 days 116,29 kg. Similar differences between bulls and heifers are statistically highly significant also for Charolais calves. At the age of 120 days the bulls are heavier than heifers by 18,45 kg, at 210 days by 29,16 kg and at the age of 365 days this difference amounts to 115,59 kg. The study covers also the investigation of the effect of mother´s cross height on to the rate of calf growth. Considered statistically, no such effect has been revealed for calves 120, 210 and 365 days old. The investigation of the effect of the calving month has brought us to a conclusion that the heaviest calves are born in March and April, with the differences in individual months ranging on significance levels p {>} 0,001, p {>} 0,01 and p = 0,05. In both breeds we have also investigated the effect of the serial number of the birth on to the live weight. For the Charolais breed, the highest weight has been found for calves with serial number 3, 4 and 5. For the calves of the meat-type Siemental breed it has been found that the calves born as the second one reach the highest weight at the age of 120, 210 and 365 days,the results obtained being statistically highly significant (p {>} 0,001) and probably significant (p = 0,05).
