Zhodnocení konkrétního malochovu zaměřeného na chov prasat
Šarapatková, Anna
This thesis deals with the evaluation of selected utility parameters that were monitored in a specific small farm engaged in pig fattening. The first part of the work contains a literature review. Firstly, the situation in the field of pig breeding in the Czech Republic is described, including pig breeds and their utility properties. The method of housing, nutrition, and care for pigs during fattening from piglet to slaughter is then described. In the second part of the bachelor thesis, the specific small farm is described and the monitored values are presented. These include average daily gains, average feed consumption, and feed conversion. These parameters are evaluated, and measures to improve production efficiency are proposed for the farm.

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

The average daily gain was 886 g with feed conversion ratio of 2.86 kg and the mortality rate of 2.62%. In 2021, the average initial weight in fattening was 28.8 kg and the average final weight reached 112.0 kg. The average daily gain was 896 g, feed conversion was 2.86 kg and the mortality rate was 2.22%. In 2020, the average carcass weight was 86.0 kg and the lean meat content was 57.5%. In 2021, the average carcass weight was 88.7 kg and the lean meat content was 58.5%. In 2020, most carcasses were classified in class E (62.0% resp. 42.7%), the second most numerous class was class U (22.8% resp. 24.6%), followed by class S (12.4% resp. 29.4%) at the slaughterhouse I resp. II. The results in 2021 were similar. 65.3% resp. 60,8% of carcasses were included in class E, 18.4% resp. 10.7% in class U and 14.0% resp. 27.3% in class S at the slaughterhouse I resp. II.

Vyhodnocení ukazatelů výkrmnosti v chovu prasat
ROHÁČEK, Daniel
The aim of this thesis was to evaluate fattening parameters and carcass value of pigs at a particular agriculture company. Parameters of fattening were monitored in terms of farms, i.e., farm N (84 fattening cycles) and farm M (93 fattening cycles) and in terms of year, i.e., the years 2018-2020. The initial live weight of pigs in the farm N was 24.8 kg, in the farm M was 23.0 kg (p < 0.05). The final live weight in the farm N was 115.2 kg. However, in the farm M the final live weight was higher, namely 117.3 kg (p < 0.05). The average daily gain in the farm N was 979 g, but in the farm M was 10 g lower. Feed mixture consumption per 1 kg of weight gain was almost identical in both farms. In the farm N the feed consumption was 2.34 kg and in the farm M was 2.33 kg. Feed mixture consumption per day in the farm N was 2.29 kg, in the farm M was 2.25 kg (p < 0.05). The mortality in the farm N was 1.57%. However, mortality in the farm M was higher, namely 1.99% (p < 0.05). Total of 2 498 carcasses from the farm N and 2 771 carcasses from the farm M were used for evaluation of the carcass value. Subsequently, the average carcass weight in the farm N was determined at 88.5 kg with 58,1% proportion of lean meat. The average carcass weight in the farm M was 93.2 kg with 57,7% proportion of lean meat (p < 0.05). Most of the carcasses from both farms were ranked in the grading class E (farm N - 71.0%, farm M - 71.7%). 17,7% of carcasses from the farm N and 14.2% carcasses from the farm M were classified in class S. Finally, most of the carcasses from the farm N were classified in the weight category 80-89.9 kg and in the case of the farm M the most carcasses were classified in the weight category 90-99.9 kg.

Prudukčná úžitkovosť prasiat a faktory na ňu pôsobiace
Szabóová, Edina
The bachelor thesis focuses on the production efficiency of pigs and the factors affecting it. The beginning of this work is focused on the importance of pig farming, the importance of this sector and the level of production in Czech Republic. This chapter is substantiated by current data on the amount of pigs intended for slaughter. In the next part the production performance is described, with a focus on fattening capacity and carcass value. The issue of the production of animal products has a solid place in the development of the economy. That is why it is necessary to mention the endogenous and exogenous factors that can positively or negatively affect pigs and thus influence the profitability of the farming. The last chapter of the bachelor thesis contains the description of fattening capacity in the conditions of a small farm. This literature search offers a range of information in one place, with the aim of providing a comprehensive picture of the issue of pigs production performance.

Produkční užitkovost prasat
Otáhalová, Silvie
The bachelor thesis deals with production characteristics of pigs. At first, the basic production characteristics, fattening and slaughter value are characterized. Fattening is mainly determined to the average daily gain and conversion of nutrients from the feed received. Carcass value is determined by the quantitative and qualitative characters that affect it. In relation to the slaughter value, carcass yield and carcass body are characterized. Another part of the bachelor thesis is devoted to the description of factors that influence production performance. The internal factors are the influence of the breed or hybrid combination, the influence of age or weight, the influence of genetics and the influence of the endocrine system in relation to the influence of gender. Furthermore, the thesis deals with characteristics of external factors influencing the productive performance traits, namely nutrition, housing and the influence of handling with pigs before slaughter. The last part shows the current productive performance level of pigs in the Czech Republic.
