Hlukové emise v chovu prasnic
DVOŘÁK, Hynek
This thesis focuses on the noise pollution in sow farming. The first part of the thesis theoretically examines topics concerning noise, sow farming and a proper agricultural practice. The other part of the thesis introduces the aim of the work, describes the measuring technology, the locations objects and the method of the whole measuring process. The obtained values are later on shown in the form of graphs and compared with the hygienic limits. With the occurrence of any violation of these limits, an anti-noise action is suggested.

Posouzení ozdravovacího programu v chovu prasat
MOTYKOVÁ, Markéta
This bachelor thesis is evaluating results of primary herd of rows remedial program. It i also about following the principles of correct zoohygiene and veterinary prevention, then about reviewing the influence of remedial program on reducing respiratory diseases occurrence. It also pursues parametres rows's reproduction yield in herd and follow-up pre-fattening and fattening.Given to these circumstances my goal was to evaluate the results of remedial program of whole pigs herd in ZD Bělčice, to assess following the principles of correct zoohygiene and veterinary prevention and also to evaluate the results of reproduction and loses for a year before repopulation of stud (2012) and after the repopulation (2014). I also focused on comparing the results of yield using parameteres like number of living newborn piglets, weaned piglets, lost piglets in pre-fatteing and fattening for those two mentioned years. I focused on following hygienic loop of operation, observing cleanliness and desinfection. I also observed preparation, washing, desinfection of sows, which are removed for farrowing. Next I dealt with hygiene and desinfection during veterinary interventions and with keeping feeding belts and mixer clean. I observed monitoring of regular controls and analysing food samples and then regular monitoring of samples examined for respiratory diseases in this stated herd. I observed visits on farm, respecting restrictions of accessing the herd. At the end of my thesis are all mentioned requirements evaluated.

Využití metody repopulace ke zvyšování reprodukční užitkovosti prasnic
Nevrkla, Pavel
The aim of the dissertation thesis was to analyze reproductive performance of sows recovered by the means of repopulation, in operating conditions of a production farm. Another objective was to analyze productive parameters of piglets and losses of piglets from birth to weaning. Based on achieved results it can be stated, that repopulated group of sows showed significantly higher reproductive performance compared to sows before repopulation. An anylsis of reproductive performance of gilts coming from two commercial programs was also conducted. The differences in reproductive performance were not found significant, however the differences in the losses of piglets were significant in favor of the program II. From the analysis of the productive parameters of piglets it is evident that piglets in the commercial program I had better growth intensity compared to piglets in the commercial program II, demonstrated by significantly higher weaning weight and daily gain of piglets. Also reproductive performance of repopulated sows from the 1st to the 4th litter was analyzed. The results indicate that there is a significant difference between parities. Reproductive performance had increasing tendency up to the 3rd litter and in the 4th litter it decreased. The most frequent causes of discarding of sows were problems with musculoskeletal system and abortions.

Analysis of birth weight and losses in piglets
DULOVCOVÁ, Ivana
The aim of the theses was to evaluate the characteristics of reproduction of sows with focus on birth weight of piglets and losses of piglets. Forty-two litters were studied. The average number of piglets born alive was 12.38. The average percentage of stillborn piglets per one litter was 5.43, the percentage of mortality until the weaning was 27.8. The average birth weight of piglets born alive was 1.29 kg. Most of the piglets (51%) fell into 1.051.5 kg category with an average weight of 1.30 kg. The relationship between number of piglets born alive and their birth weight was r = -0,121. The average weight of stillborn piglets was 1.08 kg. The gestation period of gilts was 0.28 day shorter than the sow gestation period and they gave birth to 4.03 fewer piglets born alive than sows. The gilts showed a higher proportion of piglets' mortality until the weaning (the difference was 3.46%). The sows showed higher average weight of piglets born alive (the difference was 0.19 kg). The sows with longer gestation period (114 days) gave birth to 0.15 piglet born alive more than the sows with shorter gestation period (less than 113 days). The sows with shorter gestation period showed smaller proportion of stillborn piglets from all born piglets, the sows with longer gestation period showed smaller proportion of piglets' mortality until weaning. In deliveries longer than 8 hours 10.37 piglets were averagely born alive, which was 2.52 piglets less than for sows with deliveries shorter than 6 hours, or 2.6 piglets less than for the sows with deliveries from 6 to 8 hours. In deliveries shorter than 6 hours was the highest number of stillborn piglets. The highest mortality of piglets was until 24 hours after a birth (33%), 28% of piglets died the second day, 12% died the third day and 9% the fourth day. The mortality decreased noticeably from the fifth day after the birth.

Transfer of genetic potential for reproduction in sows production sector
NÝVLT, Vladimír
The purpose of this thesis was to describe the transfer of genetic potential of sows in production sphere and evaluate concrete results in reproduction breeding sows Agricultural Society Kosova Hora. On large-scale farrowing sows were evaluated Doublovičky basic herd of sows, which consisted of 440 to 520 pieces. sows. The basic herd always has been about 35 nucleic sows (P 1065). The rest of the herd was an offspring of hybrids F1 (C 1023) program the PIC. The sows P 1065 were investigated causes selecting progeny namely: 1) For lack of development, which was evaluated from birth to breeding gilts adulthood. 2) The number and formation of the teats. For breeding were required to at least 12. They can not be crater, but well formed to have good piglets suck breast milk from them. 3) Reproduction in gilts were evaluated after conception periodic (cyclic) heat. The minimum requirement for the first 8 piglets which are born alive. For the basic herd was evaluated the age structure. It was incorporated into three groups and evaluated that, the largest selection of sows was for lack of milk production, limb injuries, poor breeding condition and the possibility of further embedding. The largest selection of sows takes place after the third to fifth lactation.

Health assessment of the selected pig management
SKÁLOVÁ, Eva
Aim of the thesis is to evaluate health in selected pig stock. Adherence to vaccination programs and good veterinary prevention principles, provision of appropriate stall, good care and feeding, piglets wean timing, selection of breeding animals, choosing of reliable personnel and other factors have great impact on health in pig stock. Considering above mentioned factors, the aim of the thesis was to asses health of sows, piglets and fattening pigs in chosen farm Ponědraž ltd. and asses influence of vaccination on production in time period 2010 to 2011. Further it was neccesary to asses observance of good hygiene praxis in enterprise, including using of hygiene loop by personnel and to find out, if the enterprise is equiped with systematic protection against infectious diseases. To evaluate stall by pig categories, animal welfare and positive influence on health and increase of pig production as a whole. Further to asses compliance with EU legislation. Aim of the thesis is to evaleuate new vaccination scheme against respirational diseases, it´s influence on increase of production and improving of healt in observed stock. In the end are all above mentioned requirements evaluated.
