Faktory ovlivňující zabřezávání a trvání gravidity u Starokladrubského koně
Malinská, Martina
Diploma thesis is concentrated on analysis of selected factors affecting gestation length in mares of warmblood breed Old Kladruber horse. Gestation length was significantly affected by the month of conception, the month of foaling and the year of conception. The age of mares in the time of conception or foaling did not influence gestation length. Even the sex of foals or alive and dead foals did not significantly affect gestation length. In conclusion, gestation length in mares is affected by a large number of factors and not all of those have been discovered yet. The knowledge of these factors is very important for the most accurate determination of parturition date.

Reprodukce v chovu holštýnského plemene skotu
Klimešová, Michaela
This bachelor thesis discusses reproduction of Holstein cattle. It deals with reproductive characteristics of the breed. In the first part it summarizes the basic morphological and physiological characteristics of female and male of Holstein cattle. The thesis deals with the most fundamental and nowadays even the most commonly used methods of heat detection. The second part deals with the selection of appropriate technology for successful insemination conception of dairy cows and heifers. We demonstrate the success of artificial insemination methods to detect pregnancy which are also summarized and described. In the third part of the thesis deals with the birth cow. The birth also includes the development of the foetus and treatment of the calf after the birth. For successful herd management is necessary to know the main indicators of reproductive properties which are also included in this study. Holstein cattle is very sensitive to changes in nutrition, but also changes in climatic conditions and this has resulted in lot of health problems which are reflected primarily in reproduction.

Biologické a ekonomické aspekty délky březosti mléčného skotu
Janštová, Veronika
Thesis is concentrated on analysis of the various factors that affect gestation length of Holstein breed. There were also analyzed the economic aspects of gestation length in the dairy cattle. Gestation length was considerably influenced by the month of conception, sex of calves, birth of twins and parity. A significant effect was also recorded for alive and dead calves. The results show that the gestation length in cows is influenced by a number of factors which need attention.

Vošalíková, Jana
Thesis is aimed to analyze effects on the length of pregnancy, calving interval, service period, insemination interval and number of inseminations in the herd of the Czech spotted cattle. The study was performed on 1697 animals. The length of pregnancy was significantly affected by parity, twins, death of calf and gender of calves. The calving interval was significantly influenced the length of pregnancy, number of inseminations, length of insemination interval, service period and month of calving. The length of service period was influenced by the length of insemination interval. The number of insemination was significantly affected by parity. Reproduction in the herd is affected by a number of factors, so it is necessary to pay special attention to them.

Reprodukce slona afrického (Loxodonta africana) v Zoo Zlín - Lešná
Šimková, Daria
ŠIMKOVÁ, D. Reproduction of an African elephant (Loxodonta africana) in a Zoo Zlín – Lešná. Mendel University in Brno, 2019. Diploma thesis. The thesis analyzes the issue of reproduction of critically endangered species of African elephant. The work is focused on monitoring of animal weight and blood test results during the reproductive cycle. The first part describes the general characteristics of the reproduction cycle of the African elephant, the issue of pregnancy and childbirth, and the female reproductive system. In the second part, there are given data from three particular elephants from the Zoo in Zlín. The data are processed into graphs and these are then commented on and compared with the conclusions of already conducted studies and scientific papers. At the end, all the knowledge and forecast of the African elephant reproduction in the Zoo - Lešná in the future are evaluated. All the results show that females are fully capable of reproduction and there is no need to make any changes in the breeding of these animals.

Svobodová, Simona
Bachelor thesis is concentrated on analysis of factors that affect gestation length. Gestation length was considerably influenced by the month of conception, month of the birth calves, sex of calves and parity. A significant effect was also recorded for the birth of single and twins, as well as by alive and dead calves. The results resulting from factors affecting gestation length should be given considerable attention regarding the correct determination of the onset of parturition.

Zhodnocení komplikací způsobených během porodu a v průběhu puerperia skotu
Zezula, Filip
My bachelor thesis focus on the most common complications in the birth and the puerperia period of cattle. This thesis goes from my own research, where I was watching dairy cows during the birth and dairy cows with calves during puerperia from January 2018 till the end December 2018. The cows were monitored and evaluate the most common complications during birth and puerperia period, effects influence these complications and health care of dairy cows and young calves with these disability. The aim of the thesis was to focus on the most common complications in a classic production at cattle for milk yield and influences that cause these productions the largest complications now and in the future. In this thesis I focus on the period starting with gravidity till the birth and complications during this period. In the next part of my bachelor thesis I am trying to focus on common problems with abnormal calf position in the womb and how is important well-trained and qualified worker during the birth. In the thesis I am focus on common complication during puerperia in the stud that I watched. I was evaluate the complications, how we can have best solution for better production and lower economical train when cows and young calves have some disability.

Výživa březích a laktujících klisen, hříbat a mladých koní
KLIMEŠOVÁ, Ludmila
The horses' diet is a complex difficulty which challenges horse breeders. The main problem is that many times horses are overfed and breeders reduce the amount of nutrition consequently. This combination leads to an imbalance in the horses' nutrient uptake and lead to health problems. Professional breeders choose their horses because of their sportive performance and fast growth. Especially these horses need a balanced diet. If a balanced diet is not given, an incorrect feeding technique can lead to complications in a horses' growth and its bone grafting. The aim of this bachelor thesis is to describe the main aspects of horse feeding with a focus on pregnant mares, foals and young horses. Further this thesis addresses health problems causes by a faulty feeding and feeding technique. Based on the aspects covered in this bachelor thesis a recommended daily feeding dose for the selected horse categories will be given.

Vyhodnocení přesnosti vyhledávání říje a zvýšení míry zabřeznutí krav využitím systému zaznamenávajícího pohybovou aktivitu
BUREŠOVÁ, Michaela
In connection with growing modernization of technological systems in milk cow farming it comes to progressive innovations within monitoring motor activity. The motor activity is besides other things connected with the possibility of searching for estrus and detecting and eliminating false estrus. It is possible to suppose, that it becomes evident with increased accuracy of searching for estrus and bigger success rate by cow fertilization. It was discovered, that SCR system helps to improve reproduction. By reproduction indicators favourable values were recorded, namely: days open - 85 days, calving interval - 420 days to first service - 121 days. This year results get considerably better if compared with results from last years, when SCR system was not implemented. Success rate of insemination has risen by 36 %. It is evident, that measuring of motor activity enables us to precisely determine the right time of ovulation and therefore it increases the percentage of successful fertilization.
