Záchrana a regenerace plemene skotu české červinky
VACEK, Tomáš
The aim of the thesis was to create a clear literary study on saving the breed of the Czech Red cattle with the balance of the results achieved during the regeneration process. Work includes the regeneration process, related breeds, state aid, studbook, breeding bulls, numerous states, the number of farms with breeding conditions and the appreciation of the exterior. Within its processing, milk yield from database (123 lactations of 35 cows) was evaluated and compared with the breeding goal and literature. Fertility age at first calving (32 times) and interim (91 times) from the monitored cows were also evaluated. These data were then compared with the Polish Red Cattle. Meat performance was evaluated in relation to the growth of three breeders (113 individuals) and compared with the breeding goal and literature. Development of weight of cows and bulls from the 17th century to the early 21st century was also compiled from literature, and then compared with the Polish Red Cattle and Angler Cattle.The study suggests that state support has mostly declined during the years 1997 2015. Populations of the Czech Red cattle (198 individuals in 2015) and number of farms (30 pieces in 2015) have predominantly increased. Milk yield (2550 4409 kg, 4.18 to 4.30% fat and 3.46 to 3.50% protein) generally met the breeding goal. Age of first calving (30.5 months) and the interim period (439 days) lagged behind the Polish Red breeds. The meat production in heifers in one hundred days (110 kg) and at 365 days (267 kg) just met the breeding goal. In the case of the average daily gain increase (0.641 to 0.888 kg / day), the breeding goal has not been met. Bulls in one hundred days (130 kg) crossed the breeding goal, as well as for the average daily gain (1.001 to 1.055 kg / day). A comparison of the development of the weight of cows and bulls suggests that Czech Red cattle held approximately the same weight from the beginning of the 20th century (488 kg in the 21st century).

Vyhodnocení růstových schopností českých červinek v podmínkách chovu bez tržní produkce mléka
KOVÁŘOVÁ, Tereza
This work focuses on the evaluation of the growth capacity of czech red cattles in breeding conditions, without market production of cattle. A whole herd of czech red cattles was regularly weighed. The Czech Association of Cattle Breeders provided data from KUMP, which was added to the data. In statistical processing the data were compared with the growth capabilities of meat breeds (hereford, meat simmental, charolais and limousin) kept under similar conditions. A sample of blood was collected from selected individuals and processed by biochemical methods. Statistical analysis showed that in the weight at the age of 120 days there is a statistically significant difference between czech red cattle and meat simmental and charolais. Comparing the weights in 210 days and comparing the gains, there was no statistically significant difference between any breeds. Czech red cattle thus showed very good growth abilities. It was also found that calves from the ZF JU averaged better in terms of increments than the average of the whole population as early as 2010. Herd health status was evaluated as good in terms of hoof and limb excellent. The blood test showed a tendency to stress caused by animal manipulation and stabling in wintering grounds, as in a closed stable without enclosure. The Czech red cattle has been shown to have easy births without help, which is 99% and good level of reproduction. In conclusion, the czech red cattle is very suitable for extensive breeding with a year-round stay outdoors and is capable of achieving comparable increments such as extensive breeds of meat breeds and is ideal for the production of cattle for fattening.

Czech red cattle breeding in the suckler
NABYTÁ, Michaela
Bachelor's thesis is focused on the comparison of the economics of Czech Red cattle (School Agriculture Company Haklovy Dvory) suckler herd with selected beef breeds (Aberdeen Angus and Limousine). Companies with identical and comparable rearing conditions natural breeding, systematical using of pasture possibilities, carrying out meat performance recordings, batch calf rearing and similar sea level etc., were compared. Main product of these companies is feeder cattle. Two factors affect realization of feeder cattle. The first one is its weight and second one is price per kilogram of live weight. It was found, that average daily gain was 1109 g and average weight 240 kg (210 days) of Czech Red cattle calves. In contrast, beef breed Aberdeen Angus reached 1402 g (P 0.001) average daily gain and weight of 308 kg in 210 days (P 0.001). Beef breed Limousine reached 1303 g average daily gain (P 0.01) and average weight of 301 kg in same age (P 0.001). The average price of Czech Red feeder cattle was around 50 Kč per kilogram, price of Aberdeen angus feeder cattle was 63-68 Kč per kilogram and price of Limousine feeder cattle was 73-83 Kč per kilogram of live weight. The differences were calculated in final prices and the subsidies (4,000 Kč per heifer) were taken into account. According to this calculation rearing of Czech Red cattle and production of feeder cattle is still having a worse economic outcome (in average 4,145 Kč (Aberdeen Angus) and 6,401 Kč (Limousine) respectively), than beef breed as a result of lower daily weight gain and also lower price.

Congenital disorders by cattle
KOSOBUDOVÁ, Hana
In the framework of this thesis was performed genotyping of 46 specimens of the breed Czech red cattle from the University farm in Czech Budejovice, which monitored the incidence of autosomal recessive genetic disorders, specifically bovine citrullinemia (BC) in exon 5 and deficiency of blood coagulation factor XI (FXI) in exon 9 and 12. Genotyping for BC was done using PCR/RFLP methods and for the disorder FXI in both exons genotypes were determined on the basis of different length of fragments using PCR technology and horizontal agarose electrophoresis. The presence of mutant allele was detected only in the locus for BC and that is in 7 heterozygous carriers, who produced three bands with a length of 185 bp fragments, 103 bp and 82 bp. The frequency of mutant allele and the frequency of heterozygous carriers to 7.6% and 15.2%. Results of the study show that the presence of mutant allele for BC in our tested panel of animals is relatively high. In the future it will be necessary to adopt measures that will lead to the elimination of this allele. Otherwise, its further dissemination would have a negative impact on the health of the population and there might occur complications in the regeneration of Czech red cattle, which is one of our farm animal genetic resources. The literature review deals with the problems of congenital disorders and discusses the importance of health heredity and understanding of the genomic information of cattle.

Breeding of genetic resource Bohemian Red cattle at the University Agricultural Enterprise, SBU in České Budějovice
ŤOUPALOVÁ, Michaela
At the turn of the 19th century a Czech red cattle, the breed, which was in our conditions bred a long time ago, was crossbreeding with a simen{\crq}s bull. Czech red cattle were gradually decreasing until now, when it is at the critical limit. At the 1991, in Department of Genetics, Breeding and Nutrition, at Faculty of Agriculture, University of South Bohemia, has begun regeneration of this rare, for our conditions original, breed. The Process of Bulls absorptive breeding of Czech red cattle has begun. Czech red cattle have by now more then 162 pcs. There are kept 43 head of cattle in the case of breeding under warranty ČZU Prague. JČU in Č.Budějovice has got 119 individuals under its guarantee, of which 60 is kept on the school farm Haklovy Dvory. At research was analyses data about growth and development of calves breeding without market production of milk and Data of cow milk efficiency breeding for milk production at stable manner. The highest milk yield was achieved at 173 days lactation. The Total quantity was 1 469 kg of milk. The highest average content of milk fat was 3,80 %, and content of milk protein was 3,52 %. Index of growth and development was calculated on age 120 {--} 210 days. Average weight of 4 cows at the age of 120 days was 114kg. The highest increase of weight was noticed at a bull {--} calf and was 934 g. Average weights of 2 pcs. on unified age 210 days was 221kg. The highest growth was achieved at a heifer with its 1 038g. Meanwhile analysis of genetic structure of population has begun and on the basis of results was characterized number of locusts and microsatellites at given population. Genotyping of locusts for DGAT, GH, b {--} LG, PRL, IGF BP3, PIT1, BLAD, LEP, DUMPS, b {--} CN, kappa casein, beta casein und ALFA S1 casein was performed in the set of 272 animals. Frequency was observed in microsatellites RM 012, BOVCASK 35, BOVIRP, BTO BCAM, BOVPAI, BOVSEMRN, SRC 97, IGF BP3, CSS 004, IDVG A - 9, BM 6117, BM 148, BM 4621,BM 6438, BM 2113, BM 1824, BPA, BMS1658, INRA 107, INRA 23, ETH 3, ETH 225, ETH 10, TGLA 122, TGLA 126 and TGLA 227.

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.
