Bezstarostiová, Martina
The main objective of the Thesis was to analyse the reproductive performance of sows in the selected breeding. Data collection took place in Vemas a.s, which is engaged in pig breeding. The data was gathered in this breeding in the period of August 8 2016 to July 31 2017 at sample of 938 sows in 1761 litters. In the litter, the age of first fertilization and parturition of sows were monitored as well as the length of gestation period itself and gestation period depending on the number of alive or dead born piglets in the litter. Furthermore, the amount of all born piglets was observed, alive and dead born ones in the litter, the number of mummified piglets, the amount of weaned piglets and the loss of piglets from birth to weaning in connection to the litter order of the sow. Most of sows were fertilized between days 230. and 249. of their age, while parturition appeared between days 350. and 359. of their age. The average length of gestation period was 115,38 days. The biggest portion of live born piglets (14,08 cases per a litter) was born at the length of 113 days of gestation period, the smallest portion of dead born piglets has been found at the lenght of gestation period between 118 and 119 days. Most of all (14,72 cases per litter) and of alive born piglets (13,91 cases per litter) were observed in the third litter, the amount of dead born and mummified piglets in the litter went up in relation with the litter order. The number of weaned piglets in the litters was fairly balanced, in average 12,12 cases per a litter. The losses between the birth and the weaning were the highest in the third litter (10,42 % out of live born piglets). The breeding reaches excelent results which are also proven by PICtrag league where the breeding came first two times in a row.

Vliv technologie ustájení na mléčnou užitkovost a ekonomiku chovu dojnic českého strakatého skotu
Bezstarostiová, Martina
The aim of bachelor thesis was to assess impact stabling technology on milk production and economy of breeding of Czech Fleckvieh cattle in three economic cooperatives with a different type of stabling technology. The first section was devoted to literary review; we focused on the characteristics of the Czech Fleckvieh cattle, then on technology of stabling and economy of breeding. In the practical part, we are pursuing three selected farms in terms of milk production and the economics of farming. Compared to obtained data, the volume of fat, protein, somatic cells and total amount of microorganisms in milk, costs connected with the technology of stabling and other costs connected with the breeding of dairy cattle. Based on the results the most economical technology for breeding of dairy cattle was evaluated. Out of the farms in scope came out best the farm with boxes and straw. Milk production was 20.5 kg of milk per cow a day, with satisfactory quantity and content of milk components. From the economic point of view it has the lowest total cost of stabling cows. The results of bachelor thesis will serve to the monitored farms, as an example of strengths and weaknesses of their technology of stabling.
