Vliv bezobilné komplexní krmné směsi k výskytu toxémie u morčete domácího
KOPOROVÁ, Lenka
This diploma thesis is focused on the observation of the influence of nutrition on the presence of toxemia, the birth weight of young and their viability in domestic guinea pigs. An observed breeding of animals was determined, which was first given a commercial feed mixture containing grains. Subsequently, the breeder decided to make a change and switched to grain-free feed. All values were carefully recorded during the monitored years and then compared with each other. Great emphasis was placed primarily on the results of the occurrence of toxemia in pregnant females, as the hypothesis of today's professional literature, which increasingly points out that we can prevent this disease in guinea pigs by giving grain-free feed, was to be confirmed. The results showed that diet does not have a big effect on how many newborns are born during one gravidity and how many of them die during the first days of life. However, the feed, for example, influenced the birth weight of the guinea pigs, as the feed containing grains resulted in larger newborns being born overall. A significant influence of the animal's diet was observed in the occurrence of abortions and toxemia in females, when after the transition to a new grain-free diet, these problems completely disappeared.

Strnadíková, Veronika
The bachelor thesis deals with the issue of nutrition of pregnant mares and is processed in the form of a literature search. At the beginning of the thesis there is an introduction to the subject, which is devoted to the characteristics of the equine sexual cycle and foaling. The aspects that influence them are described, as well as the reproductive and digestive organs, the development of the foal in the mother’s body and a description of the body score condition of the horse. Subsequently, two chapters are focused to the nutritional requirements of mares in early and late foaling and the differences between them. The last chapter describes specific types of feeds and their suitability for broodmares. Selected complete feed mixtures – granules and mueslis – are also summarised, with a description of their composition, recommended dosage and in tables is shown the content of the most important essential nutrients – digestible energy, starch, nitrogenous substances, fat, fibre, calcium, phosphorus, vitamins A and E and lysine.

The literature review presented in the bachelor thesis focuses on the ma-nagement and characterization of cattle breeding, specifically the Aberdeen Angus, Limousin, and Charolais breeds. The following chapter describes ecological ag-riculture, as the thesis includes companies that breed cattle in organic farming. The upcoming chapter of the thesis centers on the reproduction of beef cattle breeds. The aim of this thesis was to conduct a comprehensive and continuous analysis throughout the year by which to evaluate the level of reproduction and ma-nagement. The practical part focuses on evaluation the course of delivery, pregnancy diagnosis results, weight of calves at birth and weaning, and the results from semen examination. The data for this thesis were collected from six companies using ac-companying lists of cattle, animal husbandry records, and bull spermograms. In the conclusion of the thesis, the results are summarized and evaluated. Companies specializing in Limousin and Charolais breeding include their bulls in herd for approximately two months. The company that focuses on breeding Aberdeen Angus has its bulls in herd for most of the year. More frequent occurrence of difficult births was recorded for the Limousin breed at the Rolnická Skalná company, and their number significantly exceeded the average incidence of complicated births for this breed. A higher incidence of di-fficult births was also analyzed for the Charolais breed at the SPO-ZEM Nový Kos-tel company. The number of difficult births recorded at the company specializing in breeding Aberdeen Angus slightly exceeded the breed's average. The highest success rate of pregnancy was found in the companies SPO-ZEM Nový Kostel, Farmy Třebeň, and Anonymu. The Naturland company achieved unsatisfactory levels of pregnancy rates. Companies breeding Limousin achieved lower birth weights, nonetheless the values were satisfactory. Weaning weights of calves in these companies were suita-ble. Companies focused on breeding Charolais achieved unsatisfactory average birth weight values but excellent weaning weight values. For the Aberdeen Angus breed, satisfactory average weaning weight was achieved for heifers, while the weight of bulls was lower than usual for the breed. From the total of 12 monitored bulls, all were fertile at the beginning of the breeding season, infertility was diagnosed in three bulls, and one bull had a high number of immobile spermatozoa. In these bulls, a treatment was applied, which was found to be effective only in two breeding males after the third collection. Bulls for which the treatment was ineffective were removed from the breeding pro-gram.

Janštová, Veronika
Bachelor thesis is concentrated on analysis of factors affecting gestation length in dairy cattle of Holstein Friesian breed. Gestation length was considerably influenced by the year and month of conception, sex of calves and parity. Gestation length was also affected the birth of single and twins, as well as by alive and dead calves. In conclusion, gestation length in cows is affected by a number of factors, but they have not all been completely clarified. The knowledge of these factors is very important for the correct determination of the onset of parturition.

Furthermore, evaluation of the effect of the synchronization program on the reproduction of dairy cattle, the effect of lactation on reproduction and comparison of the results with the national average.
Faktory ovlivňující délku březosti u skotu
Vintrlíková, Daniela
This bachelor thesis focused on the analysis of factors which influence the duration of pregnancy in dairy and dualpurpose cattle. In particular, the thesis monitored Holstein milk cattle and the dualpurpose breed of Montbeliard cattle. Pregnancy duration was influenced by the year and month of the birth. In addition, the sex of the calves, the birth of twins, stillbirths and parity of breeds were among the important influencing factors. The results show that the length of pregnancy in these breeds is affected by a number of factors, and many of these have not yet been established. However, knowledge of these is very important in anticipating the onset of labour and birth.

The rejective behaviour of mares to their foals occurs relatively rare in breeding. According to the available literature, there is the evidence of this behaviour between 2 to 5 % of cases. In practice, it complicates the life of the foal, mare and breeder. According to available records, there are several forms of rejecting behavior. They have a different ways of preventing and resolving the situation. As a result of the mare's rejective behavior can be the need of human assistance with a care of the foal. In extreme cases, the behavior of the mare can result in orphanshood of the foal. Within the informations from breeders in Czech Republic, the rejective behaviour was manifested in 15 of 344 (4,36 %) of mares. This group was consisted of mares of different ages and breeds. In total these mares gave birth to 48 foals. Twenty of these foals were partly rejected by their mothers. Only 1 foal died. Two foals were not accepted by their mothers after the assistance of breeder which was necessary and these foals had to be bred by human. The most frequent manifestations is unwillingness of nursing the foal. This behaviour occurred in 13 mares. The mare normally tries to protect her foal from various environmental influences. However, in two mares this behavior was not observed. Other form of rejective behaviour is the fearfulness of mare caused by the presence of the foal. This behaviour was manifested in 20 % of them. Two mares were trying to avoid the contact with their foals. In 46,67 % of cases were demonstrated vocalization of mares to their foals. There was the evidence of 3 cases of chasing foals by their mothers. Threat manifestations are made by effort of biting (7) and kicking (4). Two mares did not sniff their foals, another mare did not show interest in licking of the foal. Both of these activities are very important in forming of social bond between mare and foal. Mares rejected the most often their foals at the age of 4 years. The rejection occurred in both primarous and also multiparous mares. Despite the fact that multiparous mares already have an experiences of parturition and maternity care of offspring.
