Věková struktura populace plemenných hřebců plemen chovaných v ČR
PÍCHOVÁ, Vladimíra
work deals with the age structure of stallions of selected breeds, which they use for breeding. These are the Czech warmblood, the Old Kladruby horse, the Czech-Komoravian Belgian horse, the Welsh pony and cob breeds, and the Shetland pony. The aim was to explain the concepts associated with horse breeding and breeding activities of stallions. In the work itself, the age structure of stallions of individual breeds was compared, in the categories up to 8 years, 8-15 years, and in the category 16 years and more. The development of these age categories is monitored in 2005, 2010, 2015 and 2020. Furthermore, the mating activity of stallions was monitored according to age, number of matings and births of foals.

Vybrané faktory ovlivňující plodnost plemene zwartbles
STAŇKOVÁ, Dana
The aim of this thesis was evaluate fertlility of the Zwartbles sheep in zhe flock of sheep breed by Mrs. Marie Schickerová. In the reporting period of 5 years (2013 2015) were a total of 429 ewes evaluated by the followinf parameters: fertlization, reproduction intensity, total rearing. Basic reproductive parameters were compared with the flocks originating from the Union sheep and goats of the Czech Republic. They were monitored factors that have or may have an impact on fertility. The first factor was the impact of age on fertility, selected second order lambing and the last was the influence line. The average fertility of the herd reached 197,13%. The average share of fertilization was assessed at 94,01%. Sterility reached the level of 5,99 %. The amount of the total breeding herd stood at 164,67%. Intensity of production reached 185,24 %.. Based on calculations, it was found a hightly significant effect of age and rank lambing fertility. Influence line was not clearly demonstrated. Statistical evaluation of indicators of fertility, the intensity of reproduction, fertilization and overal breeding showed differences in the average monitored herds compared with herds in the performance tests. In the observed herd these values were significantly higher.

Vyhodnocení plodnosti plemene zwartbles ve vybraném chovu
STAŇKOVÁ, Dana
The aim of this thesis was evaluate fertlility of the Zwartbles sheep in zhe flock of sheep breed by Mrs. Marie Schickerová. In the reporting period of 3 years (2013 2015) were a total of 261 ewes evaluated by the followinf parameters: fertlization, reproduction intensity, total rearing, infertility, rearing of lambs born and total mortality of lambs. Basic reproductive parameters were compared with the flocks originating from the Union sheep and goats of the Czech Republic. They were monitored factors that have or may have an impact on fertility. The first factor was the impact of age on fertility, selected second order lambing and the last was the influence line. The average fertility of the herd reached 200,39%. The average share of fertilization was assessed at 91,98%. Sterility reached the level of 8,02 %. The amount of the total breeding herd stood at 159,76%. Intensity of production reached 184,34 %. Mortality was 13,34% and thus survival rate of lambs was 86,66 %. Based on calculations, it was found a hightly significant effect of age and rank lambing fertility. Influence line was not clearly demonstrated. Statistical evaluation of indicators of fertility, the intensity of reproduction, fertilization and overal breeding showed differences in the average monitored herds compared with herds in the performance tests. In the observed herd these values were significantly higher.

Evaluation of the level comliance with the zoohygiene and selected indicators of welfare in agricultural operations
ŠVEC, Radim
This thesis focused on monitoring and analysing selected parameters of assessing the level of zoohygiene, comfort and welfare of breeding dairy cows housed in four monitored stable obejct. Survey, evaluation and registracion of data related to the following indicators; health status of hooves, the incidence of mastititis and reproductive performance, were performed. A reference group, wich was appropriately prepared by a local zootechnician, who knows the farm enviroment, was set to find the meeded data and they were then monitored with the help of evidence of zootechnical and veterinary records. The research has confirmed that problems with hooves and consequent lameness occours when several factors are not kept. Conversely, compliance and respecting the needs of diary cown bring very positive results. The claim that there is an increased incidence of mastitis in the grate, litter housing has been disproved.

Evaluate the reproductive performance of the Wallachian sheep
BALOUNOVÁ, Lucie
The aim of this thesis was to evaluate the level of reproductive performance of the Wallachian sheep in the flock of sheep bred by Jan Vejčík. At first the following parameters were evaluated in 457 ewes during the period 2007 - 2011: fertilization, fertility, reproduction intensity, total rearing, infertility, rearing of lambs born and total mortality of lambs. Then, using statistical methods, frequency of litters and effect of age on fertility of ewes were evaluated and the identified parametres were compared with the flocks originating from the Union of sheep and goats of the Czech Republic. Finally, the economy sales for slaughter lambs depending on fertility was assessed. The mean fertility of the flock of sheep reached 171, 77 % and the percentage of fertilization was 92, 54 %. Total breeding flock was 143, 19 %. Seven percent of the sheep was infertile, which is directly influenced by the intensity of reproduction (158,93 %). Mortality of lambs was 10, 03 % and thus survival rate of lambs was 89,97 %. The study shows that the longer the period of existence of a farm is, the higher the fertility of ewes is (almost 179 % in 2011). Also an increasing tendency of the number of sheep twins was recorded during the study (59 twins in 2011). This indicates good welfare of the animals and generally good health of the flock. Ewes reached the highest fertility at the age of 5 to 7 years. The indicators of fertility, reproduction and total intensity of rearing showed significant differences when compared with the flocks originating from the Union of sheep and goats of the Czech Republic. Significantly higher fertility, reproduction and overall intensity was achieved in the monitored flock The difference was not statistically significant (p > 0,05) except for the fertilization parameter. Sales for slaughter lambs per ewe were affected by the share of reactive sheep and total lamb mortality, this effect was, however, only about 20 % of the total dependency. Disregarding the overall mortality of lambs and reactive sheep, it would be true that higher fertility is in direct proportion with sales for slaughter lambs.

Evaluation of reproductive performance in selected breeding of sheep
BRÁZDOVÁ, Veronika
The aim of this thesis was to evaluate the reproductive performance over the period from 2007 to 2010 in selected Suffolk sheep. The evaluation was carried out on the basis of records kept in the selected breeding sheep at Agris Markvarec s r.o. and on own observations. During the reporting period was evaluated 1115 ewes, which were monitored the following parameters such as fertilization, fertility, intensity, rearing of lambs, infertility, ewes lambing, percentage of sheep abortions, stillborn lambs, mortality, percentage of breeding lambs and percentages of sheep by percent occurrence of the cast. There was also observed age structure of the ewes, the dependence of age on fertility of ewes and the effect of father mother on her fertility. In the observed breeding was found the following results, which are presented as an average over the reporting period, so the percentage of fertilization is 91.2%, fertility 145.2% and rearing 81.3%. The percentage of idleness of sheep is 8.8%, which directly affected the percentage of the intensity, which is 118.3% and the lambing percentage, which ranks lower value 81.2%. A relatively high percentage was achieved in postnatal mortality, which is 11.4%. Percentage of sheep abortions in the average is 5.4% and the percentage of stillborn lambs is 4.9%. Breeding lambs 92.3%. The effect of age of ewes on fertility was confirmed by F - test for the significance level of p ? 0,05. Subsequent testing has been demonstrated median significant differences between groups of ewes aged 2 and 3 years and between age groups 3 and 5 years. On the same level of significance was also demonstrated effects of father mother on fertility of mother and on the basis of the results was found that the lowest average fertility rates in the ewes, their father is out of line Yog (110%) and conversely the highest fertility rate (170,8%) is achieved for mothers whose father is out of line Harald. Further testing, which was focused on the effect of age of breeding ewes and breeding year in terms of the father´s line on the mother's fertility wasn´t demonstrated.
