Vyhodnocení reprodukčních ukazatelů u otcovských a mateřských plemen prasat se zaměřením na efekt superplodné linie
Válek, Libor
The aim was to analyze the reproductive traits in pig breeds CBU, CL, BO, D and H 84 pedigree breeding. The monitored parameters and the number of live born piglets, a number of surviving piglets, sows milk production, the length of the interim period, the number of litters per sow per year pregnancy rate. For super fertile lines (SPL) and the evaluation of the number of piglets born alive per sow, birth weight, meantime, serenity litter. Evaluation of reproductive performance in boars according to the breed. I analyzed the percentage of gestation and production of piglets, and all live births. It also monitored the birth weight of piglets depending on the gender of a boar. The obtained data were analyzed by appropriate mathematical - statistical methods. For maternal breed pigs CBU was better parametrs at all piglets born in a litter of 3.5 pc, at 1.7 live births pieces of litter and preserved 1.3 pieces per litter. In parameter milking, the difference was 2.8 kg. Results after the first pregnancy rates were the best Insemination of sows CBU and 87.3%. For super fertile lines sows were better results in all (2,1pc) and live (1,3pc) born piglets and uniformity of litter (0.7%) for sows CBU. CBU breed had the highest percentage of death13.7%, the lowest percentage of paternal breed White11%. For CBU was the best of breed boar Insemination boar EDL with 23 straight 100%. Most of all, and that 17.4 pc of live piglets and 15.4 pc were born piglets after boars DSU 21st among boars maternal breed in the results were successful pregnancy rates boars breed CL with 89.38%. For CBU breed male pigs had the highest weight after 45 boars BTK (1.52 kg) in gilts and boars after FMB 46 (1.54 kilograms). In boars breed CL had the highest average weight for male pigs (1.99 kg) over 33 AGC boars and gilts (1.77) kg after boars EJR 27th best results for piglets breed Duroc boar has EDG 21a to 1.91 kg in male pigs and 1, 71 kg in gilts. After H84-158 boars are male pigs weighing at 2.46 kg and 1.9 kg gilts. Evaluating the impact of boars on the weight of piglets born alive. It showed a statistically significant difference for birth weight of male pigs and gilts. Weights were found statistically significant differences at levels of signifikance.

Indicators of the egg yield and of the fattening in the geese breeding
KULHAN, Petr
The aim of the thesis was to elaborate a literature search about utility characters of geese and to analyse a basic statistical indicators selected indicators of egg yield and of fattening performance in the selection breeding of geese, with a view to selection and to inbreed in the Czech Republic, to the conditions for certification of selection breeding, including the purpose and mission of this breeding. Geese breeding and its technology, domestic geese properties and factors, which affect them, are described further in this work. Attention was also paid to veterinary monitoring and to care of geese breeding.
