Vliv výživy na mléčnost chovných prasnic
Ticháček, Martin
This bachelor thesis deals with the diet influence on milk production of breeding sows. The sow milk yield is the ability of females to produce milk for the needs of piglets. To maximize and optimize milk composition, an ideally balanced diet is required. Complete feed mixtures are prepared to provide esential nutrition of sows. Those feed mixtures consist from the individual feed components corresponding to the individual categories. It is necessary to pay extra attention to the essential amino acids and especially lysine for rearing of pigs. This thesis presents differences in feed technology also. These differences depend on the different sows, housing, and last but not least, on climatic conditions. The objective of this work is to provide general information about the effects of nutrition and feeding techniques on lactation of breeding sows.

Reprodukční vlastnosti mateřských plemen prasat
Mandová, Lucie
The thesis is focused on reproductive properties (fertility and dairy) of maternal breeds of pigs. At first are described the reproductive properties of sows and boars, including the external and internal factors influencing these properties. Another part of the bachelor thesis is focused on the charakteristics of maternal brees with the genetic reserve, the transverse black-haired pig. The maternal breeds are analyzed at performance of pigs focusing on development of daily gain, lifetime performance and current situation, ie a general overview of the stocks in the studbook. After the analysis, comparison is made with paternal breeds.

Reprodukční užitkovost prasat
Klimeš, Jan
The bacherol thesis is a summary of literature sources concerning reproductive yield of pigs, focusing on sows. The thesis discusses the current reproductive situation in the Czech Republic, the zootechnical measures related to the rearing of piglets and the issues related to reproduction of sows. In addition, it deals with factors influencing the reproductive yield of pigs with division into external and internal factors. As far as the external factors are concerned, nutrition, housing and stock management are discussed in more detail. Furthermore, lighting and climatic conditions are mentioned. As far as the internal factors are concerned, thesis focuses for example on breed, heritable disposition, length of the interlude, average birthweight of piglets at birth, health condition and theothers. Finally, there are several examples and possibilities/opportunities to optimize reproductive yield focusing on health, housing and nutrition in the thesis.

Zhodnocení chovu prasat na rodinné farmě se zaměřením na reprodukční vlastnosti prasnic
Králová, Marie
In this diploma thesis I focused on evaluation of reproductive characteristics on a selected family farm. In the first part, I conducted a literature study on a given topic, where I described fertility and milkiness of sows, the birth process and the fertility of boars. Further, I described different breeds that were used in an experiment. The final part of literature study focused on the general economic review of pig production in the Czech Republic and in the European Union. In the practical part of my thesis, I observed reproductive characteristics of sows raised on a family farm in Stavěšice. The practical research monitored the whole number of piglets born, the number of piglets born alive and the number of piglets weaned. Further, the weight and the gender of piglets was monitored as well as the preweaning losses of piglets, the gestation length, the average daily weight gain and the boar influence on the gender and the weight of piglets. The concluding part of the thesis consists of the economic analysis of pig production in general and the economic analysis of the farm in Stavěšice.

Zhodnocení reprodukčních vlastností prasnic ve vybraném užitkovém chovu
Behančínová, Martina
This thesis deals with the evaluation of reproductive performance of sows in pig selected utility. The literary section describes the basic characteristics of reproduction, which are fertility and milk production. It clarifies the external and internal influences on reproduction, describes the parent breeds of pigs and time of birth. It also deals with a birth weight of piglets, removal of sows from reproduction and fertility problems. The research section focuses on finding out the number of piglets born total, the number of piglets born alive, the number of sow-reared piglets, losses of all born piglets to weaning and losses of live-born piglets to weaning. The thesis also analyzes the indicators of fertility such as the length of the gestation period, the number of litters per year, the order of the litter, the length meantime, the service period, the interval from weaning to flush, the litter size and the birth weight of piglets. On the basis of these data we investigated the influence of the order of litter on the reproductive performance of sows and on a birth weight of piglets and also the effect of a boar on reproductive performance of sows and on the birth weight of piglets. The statistical method used for the evaluation was Tukey HSD test.

Growth dynamics in selected rabbit breeds
POUSTKA, Milan
The aim of the thesis was performance comparison of selected populations of three breeds of rabbits, the Moravian Blue (Mm), the Viennese Blue (Vm) and the Dutch rabbit (Ho), that is a large, a medium-sized and a small breed. The monitored aspects were the production characteristics (gain weight and carcass yield) and the reproductive characteristics (the average number of kits born, the number of all kits born, the number of live born and stillborn and successfully weaned kits, the rate of successful pregnancies, the milkness of the doe). The population of each of the breeds was monitored in a selected base of 68 litters of the Mm, 65 litters of the Vm and 84 litters of the Ho. The weight gain of rabbits was monitored in regular intervals from birth until the end of fattening, i. e. until 8 months of age in the Mm and the Vm and until 6 months of age in the Ho. The results were compared with the weight gain required by the breed standard. Based on the observed weight gain, a growth curve has been created using the Richards function in Excel and Statistica 12.0. The monthly weight gain of the monitored breeds was compared. The highest average gain in weight for the Mm was 693 g, for the Ho 480g and for the Vm 539 g. The results show a significantly higher gain in weight throughout the growth period of the Dutch rabbit than is required by the breed standard. The Moravian Blue showed a lower average increase in weight during the first five months of age than is required by the breed standard. High statistical dependence (R = 0,94, p < 0.01) between weight gain and the number of kits per litter was observed during the first month. From the second month dependence get lower. Since the third month of age, this dependence could not be proven. Based on the parameters of the growth curve, the inflection point of growth was established at 59.8 days and weight 1 528 g for the Mm, at 43.2 days and weight 895 g for the Ho and at 67.7 days and weight 1512 g for the Vm. The average number of kits per litter was 6.3 for the Mm, 6.48 for the Ho and 6.23 for the Vm. The milkness was calculated according to the weight of the litter at 2 and 21 days of age. The milkness for the Mm was 3 985 g, for the Ho 2 582 g and 3 176 g for the Ho. A significant statistical dependence (R = 0.97 0.98) between the number of kits in the litter and the milkness was found. The mortality rate was at a low level for all monitored breeds, with the highest (5 per cent) for the Vm , followed by 2.9 per cent forthe Ho and 1.4 per cent forthe Mm. Analysis showed the highest carcass yield for the Dutch rabbit (62.4 per cent), but a lower live weight gain. The carcass yield was 59 per cent for the Vm and only 56.1 per cent for the Mm. Overall, the results of the thesis show a bigger live weight gain in case of the Moravian Blue rabbit provided there are higher demands for housing and feeding. Its progeny shows a greater growth potential and, in some aspects, also better reproductive characteristics. On the other hand, the Dutch rabbit paradoxically reached a higher number of kits per litter and better carcass yield, giving meat of greater quality. The Viennese Blue rabbit had a slightly higher mortality rate than the other breeds but also a relatively large weight gain and carcass yield approaching other medium-sized meat breeds. The results of the thesis can be beneficial for novice breeders in helping them choose the right breed, as well as for existing breeders in helping them improve the strengths and eliminate the weaknesses of these breeds.

Vliv délky mezidobí na reprodukční užitkovost prasnic
Rotreklová, Lucie
The target of this thesis was to analyse what has a bearing on the length of farrow-ing interval and its particular phases and therefore the reproductive aptitude of sows. This thesis generally mentions the indicators which impact fertility and milkiness. Fur-thermore it is aimed at description of particular phases of farrowing interval and influ-ences which are caused by various factors. Among effects on length of lactation belongs weaning of piglets. The interval from weaning to service is influenced the most mainly with preceding lactation. The length of gravidity cannot be influenced, but through ar-rangements made by breeders during the gravidity it is possible to reach better results of the reproduction.
