Syndromes associated with numerical aberrations of gonosomes
Sluková, Kristýna ; Mrňáková, Hana (advisor) ; Trková, Marie (referee)
Before the offspring is born, multiple flaws in the DNA, that strongly influence its future life, can occur. These may include differences in the structure of the Chromosomes or their overall quantity. Deviations from the standard genetic attributes of those Chromosomes will cause anatomic and physiological changes on the specimen. These changes act in a repetitive manner if certain conditions are met and because of multiple combinations of symptoms, genetic syndroms with similar manifestations have been categorized and named. As these abnormalities occur in early pre-natal stages od the offspring's development, there is no way of preventing them, avoiding them or completely curing them.

Regional development of fertility in Italy between 1990-2022 Abstract The work's objective is to examine and characterise the development of fertility in Italy between 1990 and 2022 in terms of the NUTS 1 and NUTS 2 regions. The analysis in the work also addresses possible contributing reasons to changes in fertility intensity over time in different regions. The study examined basic indicators of fertility and timing, such as Total fertility rate, the mother's average age at birth, or age-specific fertility rates, using data from the Italian Statistical Office (ISTAT). based on which it investigates fundamental markers of fertility and timing, such as total fertility rate, the mother's average age at birth, or age-specific fertility rates. A chapter examining the impact of the degree of regional division on the regional differentiation of fertility in Italy supports the analysis. It looks at between and inter-regional differences and how they contribute to the overall variability of fertility in Italy during particular time periods. The research demonstrates that during the observed period, fertility in the regions varied in terms of both intensity and regional differentiation. Key words: Italy, fertility, lowest-low fertility, regions
Analýza parametrů reprodukce prasnic ve vybraném chovu
HLATKÁ, Tereza
The aim of the thesis was to analyze the influences affecting the fertility of sows (number of piglets/1 litter) in the monitored breeding from the period 2017 to 2023. The highest number of piglets was in 2023, with a total of 15.89 born, out of which 13.53 were born alive (a difference of 2.36 piglets). The lowest number of piglets was in 2017, with 13.78 born in total, out of which 12.34 were born alive. Within the genotype, the highest number of piglets was recorded in the landrace breed sows, with a total of 15.05 born and 13.52 born alive. Conversely, in the duroc breed, the number of born piglets was 10.88 in total, with 9.35 born alive. There was a consistent difference of 4.17 piglets (P<0.05) between the two breeds in both total and alive births. For hybrid sows of genotype YL and (YL)D, there was a difference of 0.88 piglets (P<0.05) in total born and 0.67 (P<0.05) in alive born. The lowest number of total born piglets (14.04) and alive born piglets (12.81) were born to sows in their 1st and 2nd litter. Sows in their 3rd-5th litter showed the most total born piglets (15.25) and alive born piglets (13.48). From the 6th litter onwards, there was a downward trend in the number of piglets, with a significant drop observed in alive born, by 0.55 piglets (P<0.05). Sows inseminated at 250 days old had a litter frequency of 13.12 total born piglets and 12.09 alive born piglets. Sows inseminated at 251 days old had a litter frequency of 14.37 total born piglets and 13.13 alive born piglets, with a difference of 1.25 total born and 1.04 alive born. With the prolongation of sow gestation length, there was a slight decrease in both total and alive born piglets. Sows with a farrowing interval 147 days had a higher number of total born piglets (15.34). With an interval 148 days, the number of total born piglets was 0.48 lower (P<0.05). The same trend was observed for alive born piglets, with a difference of 0.37 (P<0.05) between sow groups. Sows with an interval from weaning to insemination 4 days achieved a higher number of total born piglets (15.31) compared to sows with an interval 5 days (14.88), with a difference of 0.43 piglets. The same trend was observed for alive born piglets, with a difference of 0.34 piglets.

Poruchy plodnosti prasnic
Vašicová, Tereza
The bachelor thesis focuses on fertility disorders in sows. The first part describes the reproductive system, i.e. the reproductive organs of the sow; fertility and its parameters, which include internal and external factors affecting fertility, such as nutrition, microclimate, lenght of the inter-period or age of the sow. The sexual cycle of the sow i salso briefly described, covering all stages, namely proestrus, estrus, me-testrus and diestrus. The second part focuses on fertlity disorders, which are divided into congenital, which include developmental disorders or anomalies, acquired, which are most commonly caused by viruses or bacteria, and separately also infertility. For the disorders, the clinical manifestations of the disease, their onset, or prevention, and in some cases, if known, therapy are described.
Vliv vitamínů rozpustných v tucích na reprodukci mléčného skotu
Jandová, Romana
Abstract Fertility is an important factor in dairy cattle breeding. Temperature stress, lack of food, insufficient amount of vitamins and minerals in the ration or diseases can have a negative effect on it. As stated in this work, fertility is mainly influenced by the content of fat-soluble vitamins, especially vitamin E. Many authors describe its beneficial effect on spermatogenesis in males, while in females it helps maintain the fetus or ensures a suitable environment in the uterus. Vitamin E deficiency causes delayed sexual maturity and low libido of bulls. In females, keratinization of the epithelium or absorption of a non-prosperous fetus. I work as an insemination technician. In my work, I described the influence of fat-soluble vitamins on fertility. At the same, in the chapter "Personal experience" I described the effect of the addition of a preparation with protected fats and the addition of a vitamin supplement on the fertility of dairy cows. From the results of my monitoring, it follows that these preparations had a beneficial effect on fertility. Thanks to the protected fats, there was also a better absorption of fat-soluble vitamins (A, D, E) and thus a lower incidence of cysts and a higher percentage of pregnant cows after insemination.
Vliv různých způsobů aplikace kompostu na mikrobiální aktivity a růst rostlin
Přibylová, Eva
Submitted diploma thesis entitled Effect of different methods of compost application on microbial activity and plant growth with investigation of the effect of certified Černý drak compost on the growth of 12 model lettuce plants. The introductiory part of the thesis is focused on basic knowledge about soil and compost, where the issue of compost application and the presence of edafon, which has an irreplaceable function in the soil environment, is described in more detail. Furthermore, the legal framework in the field of model plants planted in nutrient-poor soil in combination with certified Černý drak compost, which was collected at a compost plant in Brno, and the development of plants planted only soil that in poor in the important content of substances needed for plant growth. In container trials, compost was applied to the soil surface and into the soil body. The aim of this experiment was to clarify and find a suitable and appropriate method of compost application in plant cultivation. After compensating for the time needed to grow the model plants, the contend of leached nitrate nitrogen, ammonia nitrogen and phosphorus was determined in the laboratry. The amount of aboveground biomass grown was also evaluated. However, the dosage of compost depends on the cultivated crop, the given soil and the time of application.
