Zootechnické aspekty inseminace prasnic
Hájek, Petr
The aim of the bachelor thesis is to provide a comprehensive view on the issue of sow insemination and to summarize the current state of knowledge in this area of agricultural production. The bachelor thesis focuses on the description of insemination and on the zootechnical aspects that influence the insemination of sows. As insemination is the most used method of reproduction nowadays, emphasis is placed on the anatomy and physiology of the reproductive apparatus of the sow. Also described are the zootechnical aspects that affect insemination and how these factors influence it. In the last part of the thesis, the insemination itself and its methods of performance are described, discussing the advantages and disadvantages of insemination, including new options such as the semen capsule and its gradual release or a product to influence ovulation.

Českomoravský belgický kůň a jeho využití v minulosti a současnosti
Bartoš, Michal
The bachelor thesis describes the history and breeding of the Czech-Moravian Belgian horse breed. Its development, current rearing and areas of its use. This breed is also referred to as the Belgian horse, or the Belgian draft horse is the most common breed of cold-blooded horses. Part of the bachelor thesis is an analysis of the frequency of use of stallions in insemination. Stallions in Tlumačov and Písek stud farms were monitored. Data collection took place in the case of Tlumačov between 2009 and 2020. Data for the years 2012 to 2019 were collected in the Písek. The percentage of conception of these stallions was evaluated. There were 11 stallions working in the stud farm in Písek, with which a total of 176 mares were inseminated. The average conception in this stud farm is 58.86 %. There were 9 stallions in Tlumačov, with which 200 mares were inseminated, with an average conception value of 68.90 %

Úspěšnost inseminace klisen ve vztahu k době ovulace
VACEK, David
Mare rate of conception is influenced by many factors. Apart from the impact of the mare and the stallion, the breeder also represents one of these factors. The aim of this master's thesis is to assess the impact of the insemination dose storage, the period between the insemination and ovulation and the mare's age on the actual conception. The results are based on the assessment of forty-nine Czech Warmblood mares from the farms of Újezd and Zduchovice. Their conception rate was monitored throughout the years 2019 and the assessed affecting factors include the kind of semen storage (frozen or fresh chilled semen), the mare's age and the period between ovulation and insemination. The initial assumption that the sort of semen storage (p-value > 0.05) influences the rate of conception has been disproven because the conception rate for frozen semen was 52 % and it increased only by 6 %, amounting to 58 % in total for fresh chilled semen. As far as the age factor is concerned, there was almost no difference (p-value > 0.05) in the ages of gravid and non-gravid mares that were supposed to conceive during their first rut. The average age of pregnant mares is 10 (n = 19), therefore only one year more in comparison with non-pregnant mares (9 year, n = 30). The influence of the period between the insemination and the ovulation on the conception rate has not been proven either. While being monitored, no period between the insemination and ovulation exceeded the recommended length. In conclusion, the breeder can lessen the impact of harmful factors on the conception rate, for example the mare's age, the period between insemination and ovulation and the kind of semen storage.

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.

Reproduction in intensification factor pig
TROJÁKOVÁ, Hana
Základním faktorem ovlivňující chov prasat je reprodukce a její intenzita. Intenzitu reprodukce lze ovlivnit vnějšími a vnitřními faktory, které zvíře obklopují. Z vnějších faktorů se jedná o roční období, výživu a způsoby ustájení z vnitřních genetické dispozice, zdravotní stav, kondice a v neposlední řadě plemeno prasete. Velká pozornost je v moderních chovech věnována hygieně chovu, chovným podmínkám a kondici zvířat. Hygiena chovu a zdravotní stav zvířat je ukazatelem kvality chovu. Velikost vrhu, četnost vrhu a životnost selat vypovídá o kvalitě výživy, stimulaci říje a inseminaci.

Analysis of reproductive performance of sows in the factory farming
NĚMEC, Petr
The work deals with the analysis of some conditions to increase the level of piglets in factory farms. In addition to the genetic material used in crossing the farm, there is really important material support: good nutrition, breeding environment and nursing care. All these requirements were fullfilled in evaulated plant. In the breeding herd, were revealed a significant effect of early estrus and early pregnancy rate in the interval weaning of piglets. The obtained data showed that the percentage is not significantly different farrowing in sows and gilts. The number of live born piglets is no significant difference in sows and gilts. That's why is advantagous to continuously include gilts in basic herd and early replacement of saws according to their health status and number of past litters. Return breeding of sows should be at the annual breeding 23 to 25 piglets per sow.
