Analýza masné užitkovosti vybraných plemen masného skotu
Ovčáček, Jindřich
The aim of the bachelor thesis was to analyse selected breeds for meat performance parameters in the Czech Republic. The analysed breeds Aberdeen angus, Hereford, Charolais and Meat Simmental were measured during the year for individual meat performance parameters such as birth weight, weight at 120 and 210 days, gain up to 120 days, gain up to 210 days, gain between 120 and 210 days, slaughter weight, average gain to age at slaughter, total gain and carcass. These results were then compared between breeds and the economics of breeding selected beef cattle breeds were also determined from these data. The result showed that breed has an effect on meat performance, with the Charolais and Meat Simmental breeds performing best and the Aberdeen Angus and Hereford breeds performing worst in the comparison between breeds. Sex within breed was also found to influence meat yield, with bulls of all breeds studied achieving higher meat yields than heifers.

Porovnání různých způsobů odchovu telat v období mléčné výživy u holštýnského skotu
Adámek, Jiří
The bachelor's thesis deals with the comparison of different methods of rearing Holstein calves in the period of milk feeding. The research was carried out in the Mír Agricultural Cooperative with headquarters in Ratiboř and on farms in Pržno and Hošťálková. On farm in Pržno, the calves are housed in a group pen with milk feeding machines Urban Alma Pro. On the farm in Hošťálková, it is the most common for the calves to be housed in individual outdoor sheds. Thesis compares the weight of calves at birth, the weight of calves at weaning and the average daily gain compering individual farms. Furthermore, the consumption of milk feed mixture is measured in the Urban Alma Pro system on a farm in Pržno. Based on my own findings, I can state that on the farm in Pržno the weight of calves at birth was lower also the weight of calves at weaning and the average daily gain was higher than on the farm in Hošťálková. The average consumption of the milk feed mixture using the Urban Alma Pro system was lower compared to the optimal average consumption. This could be caused by unfamiliarity of the new environment and possible diseases contracted by calves. The rearing of calves on the farm in Pržno was therefore more efficient for agricultural production, more beneficial from the health point of view of the calves, less financially demanding and more natural for the calves thanks to the Urban Alma Pro system. The main advantage is the possibility of drinking the milk mixture six times a day in smaller doses. In the normal rearing of calves on the farm in Hošťálková, it is at best possible to feed the calves with milk feed mixture only twice a day.

Zhodnocení růstu jehňat plemene lacaune
Šínová, Jana
The aim of this study was evaluated the growth of lambs Lacaune dairy breed. Monitoring was carried out on the family farm in Brníčko near Zábřeh na Moravě. Altogether, the study includes 168 lambs. The evaluation of growth was determined by live weight of lambs at birth, a tweaning (40 days of age) and 100 days of age. All these live weight was observed average daily gain at intervals of 0 - 40, 40 - 100, 0 - 100 days of age. The growth rate of lambs was evaluated in relation to sex, litter size, maternal age and ram used in reproduction. It was found that maternal age had a highly signifiant effect on birth weight and signifiant effect on live body weight at 100 days of age. Sex lambs had a signifiant effect on all tracked live body weight and average daily gain among birth weight. Litter size had signifiant effect on all tracked live body weights. Line of ram used in reproduction had no signifiant effect on growth or average daily gain of lambs.

Chov holubů plemene king (Columba livia f. domestica) a jatečná výtěžnost
ŘEZNÍČKOVÁ, Marcela
The literature review of the bachelor's thesis deals with the origin and domestication of the wild pigeon (Columba livia) and other representatives of the pigeon family living in the Czech Republic. Of this family, the domestic pigeon (Columba livia domestica), a domesticated form of the rock pigeon, its morphology, methods of breeding, nutrition and reproduction of this pigeon are the most described. The next chapter of the bachelor's thesis deals with the issue of the King breed, which describes the breed, care, breeding, reproduction and nutrition of this breed.

Vliv plemenné příslušnosti na masnou užitkovost býků v konkrétním podniku
Pavlíček, Václav
ABSTRAKT In this work I compared daily gain of intensive fattening beef meat bulls in a chosen farm. I was interested in: incoming weiht, average daily gain and weight during the fattening. Theoretical part points ohter aspects which influence fattening. I studied 3 groups a total of 81 bulls. Mainly these breeds were monitored Charolais, Simmental and Limousine hybrids. Charolais bulls had the highest daily gain which is 2,25 kg/day. The highest slaughter weight was the bull of Simmental. Keywords: daily gain, beef meat, fattening bulls, live weight, purebred breed, hybrid

Porovnání růstových schopností telat a mladého skotu různých masných plemen
KOVÁŘOVÁ, Tereza
Abstract Optimal daily gain in rearing and fattening of meat cattle, should be the basics of meat production. The breeder ensured the satisfactory enviromental conditions and good nutrition (wellfare), which significantly afect animals development. Gender, age, slaughter weight, nutrition, method of fattening and housing system, belongs to the main factors affecting meat production. The aim of the study was to compare average weights and calculate average daily gain of heifers and bullocks of evaluated beef breeds. Conditions of breed of all herds of meat cattle were same and all herds were housed freely. Breeds evaluated in experiment were Hereford, Simmental, Charolais and Limousin. Each herd was divided by beef breeds and gender and every herd was made up 20 - 30 pieces. Birth weight of calf was estimated according to breeds standards and employee experience. Furthermore was weighing at 5,6 and 7 months for all monitored pieces. Weighing at 12th and 14th months of age was just at the bulls. All weighings was taken by digital weighing-machine. Average gains and weights were calculated from obtained data. The highest weight from the both genders and the highest gains at bulls had attained Charolais. Limousin had best results at heifers. Except for small differences between breeds and genders were the gains same at the all monitored pieces. There was no statistically significant evidence of difference between influences of breeds and age according to statistically processed data of size of average daily gain of weight (P = 0,645862).

The analysis of beef cattle herd on family farm
ŠIMÁNKOVÁ, Karolína
The aim of the bachelor thesis was performance evaluation of Simmental breed cattle herd within the period of 2011 2013 on a private farm. The herd consisted of 39 purebred cows as well as crossbred cows. The average lenght of the calving interval was 379.4 days and the age at the first calving was 27.3 months. Herd of calves consisted of 85 pcs. Birth weight and weight at age of 120 and 210 days was studied within group of purebred calves (49 pcs). Herd of calves was categorized by year of birth, by birth order, by sex and by sire. Meat performance and carcass value basic data were obtained within group of fattened animals. Data were statistically processed in Microsoft Excel and evaluated in programme Statistica 12. Average birth weight of calves was 41.69 kg; the average weight in 120 days was 207.86 kg and 320.6 kg in the age of 210 days. Calves reached average daily gain from birth to 120 days 1.38 kg, from birth to 210 days 1.33 kg and from 120 days to 210 days 1.25 kg. When groups of calves were classified by years, statistical differences between birth weights according to year were found. Calves born in 2012 reached the best weights in 120 and 210 days of age (215.80 kg and 327.20 kg respectively). Significant differences were found especially within birth weights according to birth order; particularly within group of first-calf heifers. First born calves average birth weight was 38.25 kg, second born 40.57 kg, third born 43 kg, fourth born 41.82 kg, fifth born 42.10 kg and sixth born calves average birth weight was 47.33 kg (significant differences were found between 1. and 2., 4. and 5., 4. and 6., 2. and 6. birth order ). The average slaughter age of animals reached 561.1 days, the average slaughter weight reached 502.6 kg and the average carcass weight was 316.21 kg. Slaughter weight of bulls reached 559.20 kg and heifers 374.09 kg, observed difference was statistically significant. Statistically significant difference was also found at carcass weight.
