Management chovu ovcí plemene suffolk v malochovu
Buchtová, Nikola
The aim of the bachelor thesis is to describe the management of Suffolk sheep breeding in small-scale farming. The thesis describes all the essentials that are associated with sheep breeding on your own farm. It includes, first of all, the issue of reproduction, but also nutrition. The thesis includes practical results of reproductive indicators that were collected on a selected farm in the town of Šumperk from 2016 to 2022. The results concern the evaluation of reproductive indicators of the monitored breeding in ewes, where different success rates in pregnant stallions were recorded in individual years. Attention is also paid to the evaluation of reproductive indicators of the monitored breeding in rams, where a stagnant situation in the success rate of pregnancy from 2016 to 2020 was found. A slight downward trend was then observed. Subsequently, the reproductive indicators of the breed were evaluated, where the numbers of births, lambs reared and the number of losses were compared. Results vary from year to year.
Předpoklady úspěšné reprodukce prasnic
Doubravská, Sára
The bachelor thesis deals with the prerequisites for successful reproduction of sows. In the introductory part, the thesis focuses on the importance of reproduction and the distribution of reproductive traits. The main part describes the physiological course of reproductive traits and the influences that affect them. Furthermore, pregnancy and parturition, their physiological processes are described. Then, the factors that influence the reproductive performance of breeding sows are described. In the final part, the bachelor thesis deals with the current level of reproductive indices in the Czech Republic.
Využití aktivometrů v řízení reprodukce holštýnského skotu na ŠZP Žabčice
Šalšová, Agáta
This bachelor thesis focuses on heat detection in cattle. The thesis introduces the description of the female reproductive system, estrous cycle and its neurohormonal control. It further discusses heat and its signs – primarily an increased physical activity and what it is affected by. It explores different models of activometers; more specifically an activometer model Ovalert, which is currently used in a school farm Žabčice. The thesis concludes that activometers are very beneficial tools for breeding. They significantly facilitate work and save time. They can also duly detect and alert you to certain health conditions related to the observed parameters such as decreased activity, rumination intensity or feed intake.
Zhodnocení inseminace u ovcí s využitím kvality cervikálního hlenu
Čaky, František
The aim of this thesis is to evaluate the quality of cervical mucus in relation to insemination. This thesis describes the different methods leading to the detection of the optimal time for insemination, i.e. estrus detection, methods of sheep synchronization and methods of sheep insemination. In the practical part, reproductive indices related to insemination, cervical mucus arborization and from this determination of the optimal time for insemination and the amount and other properties of cervical mucus were evaluated.
Use of insemination in beef cattle herds
JANIŠ, Marek
This bachelor thesis deals with the evaluation of the use of insemination in a selected herd of beef cattle. The thesis is divided into two parts, theoretical and practical. The theoretical part of the bachelor thesis characterizes the concepts related to the topic.It describes the anatomy and physiology of the cow, insemination and methods, genomics and current and future trends in the field of insemination. The practical part interprets and evaluates the results of the analysis, which are based on the cow's passport cards and the record of the performance check.
Aspekty reprodukcie slona afrického (Loxodonta africana) vo voľnej prírode a v ľudskej starostlivosti
Kováčiková, Ivana
The bachelor thesis Aspects of the Reproduction of the African Bush Elephant (Loxodonta africana) in the Wilds and in Captivity deals with the reproduction of the African bush elephant (Loxodonta africana) and various issues affecting it. The text focuses on the collection, study and assessment of literature related to the reproduction of the African bush elephant living in the wilds and in zoological gardens. It also points out the importance of the development and support of the reproduction of the African bush elephants, for the amount of the animals still living in the wilds is decreasing. The first part describes the general characteristics of the African bush elephant. Its subparts deal with zoological classification, evolution, anatomy, diet and communication system. The following part focuses on the reproduction of the animals and the related social behaviour thereof. The text further elaborates on musth, heat, mating, gravidity and birth, as well as on the development of the young after they are born. The thesis concludes with the evaluation of the current state of breeding of the African bush elephant in captivity and issues related to it.
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.
Monitorování pohlavní aktivity mléčného skotu
Hrochová, Kateřina
The aim of this diploma thesis was to analyze the symptoms of estrus in cows conceived at various seasons. The study was performed in 301 breeds of Holstein cattle. There was a significant increase in step frequency, a decrease in the total lying time, the resting period and the proportion of the lying time. For deeper understanding, longer-term monitoring of this issue is required.
Monitorování pohlavní aktivity u mléčného skotu
Horáková, Nikola
The aim of the bachelor thesis was to determine the influence of the season and estrus order on the auxiliary indicators of estrus. The observation was carried out in 300 cows of the Holstein breed. Changes in movement activity, daily milk production and milk conductivity were found in estrus. No significant changes have been detected in the milking length and in the number of passages between the feed and water chute. The results indicated changes in physical activity, daytime milk and milk conductivity during the heat period.
Monitorování pohybové aktivity dojnic
Horáková, Nikola
The aim of thesis was to analyze the symptoms of estrus in conceived cows after different numbers of insemination in 2014-2016. The observation was performer on 336 cows of Holstein breed. A significant increase of step activity and ratio between activity and lying time. In the other way reducing the total lying time, the length of the one lie and the number of laps during the day. There were no significant changes in the number of passages between the feed and water chute. The results show deeper requirement researching this issue.
