Analysis of growth characteristics and carcass composition of selected hybrid combinations of pigs
KOMOSNÝ, Michal
Two hybrid combinations with an almost equal ratio of barrows and gilts (Large White Landrace) (Large White-sire line Pietrain) - experiment 1 and (Large White Landrace) Pietrain - experiment 2 were included to the monitoring (70 head). The rearing of piglets was going on in the experiment 1 from 25 to 60 days of age and in the experiment 2 from 28 to 63 days of age. Higher live weight and average daily gain were achieved in barrows of both hybrid combinations. A lower consumption of feed per 1 kg of gain was found in barrows. Feed consumption per 1 kg of gain was statistically significantly influenced by gender in the experiment 1. In the experiment 1, fattening was going on from 60 days of age and was evaluated up to 130 days of age. The first group was fed with an ad libitum diet (AD), the second group was fed with a moderate restricted diet (MR) and the third group was fed with a strong restricted diet (SD). AD barrows and gilts achieved the highest live weight and average daily gain. The lowest feed consumption per 1 kg of gain and the highest lean meat content were recorded in barrows and gilts of SR. In almost all traits, with the exception of lean meat content, greater differences between groups of feeding methods were recorded in barrows. Live weight and average daily gain were significantly influenced by the feeding methods. Feed consumption per 1 kg gain was significantly influenced by gender. Experiment 2 was going on from 63 days of age and is evaluated up to 133 days of age. The first group was fed with an ad libitum diet (AD), the second group was fed with a restricted diet from 85 kg live weight (R2) and the third group was fed with a restricted diet from 65 kg live weight (R3). Also in the experiment 2, the highest live weight and average daily gain were in AD barrows and gilts and the lowest in R65 groups. The differences between ad libitum or by restricted-fed pigs were not as significant as in the experiment 1. The lowest feed consumption per 1 kg of gain was in barrows R65 and gilts R85. Lean meat content was the highest in AD barrows and R65 gilts. Live weight and average daily gain were significantly influenced by the feeding method and gender. Feed consumption per 1 kg of gain was significantly influenced by the feeding method. The slaughter value traits were converted to an age of 148.9 days in the experiment 1. The highest slaughter weight was in AD barrows and gilts. The lowest average backfat thickness and with a related highest lean meat content (FOM) were in SR barrows and gilts. The highest pH45 was in barrows of both restricted groups and MR gilts. The lowest drip loss was in SR barrows and MR gilts. The highest IMF content was recorded in AD barrows and gilts. Backfat thickness and lean meat content (FOM) were significantly influenced by the feeding method. Lean meat content (FOM) in the AD group and MLLT area in the SR group were significantly influenced by gender. The slaughter value traits were converted to an age of 141.3 days in the experiment 2. The highest slaughter weight was in barrows and AD gilts. The lowest backfat thickness was in R85 barrows and R65 gilts. The highest lean meat content (FOM) was in the R85 groups for both sexes. The highest pH45 was in barrows AD and gilts R85. The lowest drip loss and the highest content of IMF was in barrows and gilts R65. The results of the experiment 1 for the hybrid combination (LW L) (LWSL Pn) showed that it is suitable to use ad libitum feeding for both gilts and barrows, depending on the technological and organizational possibilities of the breeder, to apply a stronger feeding restriction. In terms of costs per 1 kg of gain, it was shown in the experiment 2 for the hybrid ombination (LW L) Pn as the most suitable feed restriction from 85 kg of live weight, when the growth potential of pigs was best utilized with adequate feed conversion. Results of the trials showed excellent growth potential

Porovnání velikosti plochy ustájení na zdravotní stav a masnou užitkovost prasat ve výkrmu
KOHOUT, Martin
The bachelor thesis is focused on the influence of health status and greasy performance in comparison with the maintenance area. First, I address all the effects on pig farming, in the next section we will get acquainted with the selected farm in which the experiment will take place. The experimental hall has better results in recent losses, conversion and average consumption per feeding day. The control hall achieved a better average increase. The conclusion of the work points to the result of an experiment with the proposed measures to improve the effectiveness of fat efficiency and health.

The effect of the pre-weaning play on the coping ability of piglets
Večlová, Barbora ; Chaloupková, Helena (advisor) ; Fuchs, Roman (referee)
This diploma thesis is focused on animal play behaviour, it's features and factors that influence it. It also shows how play can be used as an animal welfare indicator and moreover that play may also improve welfare. Play is interesting from physiology and neurology point of view as well because it is able to trigger positive emotions. This thesis also describes the main hypotheses explaing evolutionary functions of play. The newest hypothesis claims that play may be a "training for the unexpected"(Špinka et al., 2001). Our experiments tested this hypothesis. We investigated if play of piglets before weaning could improve their coping with stress and reduce agonistic behaviour after weaning and later in life. Results show that play in an extra space before weaning does not influence pig's behaviour very much, but it seems to have some impact. Results also show other factors influencing agonistic behaviour of pigs - groupsize, gender and weight gain.

Ustájení hospodářských zvířat v ekologickém chovu
Večeře, Martin
This bachelor thesis is focused on styling of animals in organic farming. Itdescribes the formation, development and principles of organic farming. As regards the structure of the thesis, there is first explained the koncept of organic fading with the emphasis on the Czech context. Next, there is presented the description of formation and development of organic farming in the Czech Republic; which started in the early 90s. Finally, the thesis deals with therules and the principles of organic farming. It brieflyoutlines grazing as the basic principle of keeping animals in organic farming. The work describes housing of cattle; ether with or without market milk production; and styling of sheep, goats and pigs in term sof organic production.

Etologie prasat v konvenčním a alternativním chovu
Střelcová, Anna
The thesis deals with the domesticated pig. It involves it's history, ethological needs, expressions of intelligence and pathological phenomena when the animal's needs are not met. Furthermore, the thesis deals with the two basic methods of breeding of this farm animal, i.e. conventional breeding and ecological breeding. In order for the animal expressions in different methods of breeding to be compared, ethological observations were conducted and recorded in conventional breeding, ecological breeding and also in free-range breeding, where the conditions are most similar to those of wild boars. The observations are then compared and it is established, how well were the ethological needs of pigs met in each of the variety of breeding methods.

Srovnání depozice polynenasycených mastných kyselin ve vybraných tkáních dvou živočišných druhů
Papanová, Veronika
The diploma thesis is devided into two parts – theoretical and practical. The theoretical part deals with fatty acids, their nomenclature and chemical composition. Further the diploma thesis focuses on polyunsaturated fatty acids (PUFAs) – their analytical determination, metabolism, important representatives and influence on human nutrition. The practical part deals with the experiment, in which the fatty acids content was determined in mg/100 g using gas chromatography. Testing was carried out using model animals – rats Wistar Albino and pigs Landrace and Large White. By using statistical processing, the differences in the deposition of PUFAs in the livers of these animals, were compared.
