Vitrification, warming in sucrose-free medium and transfer of goat and mouse embryos
(2020-05-27)In farm animals, the usage of assisted reproduction programs, implying biotech-nologies such as estrus synchronization, superovulation, cryopreservation of embryos and embryo transfer, to mention some, helps to improve ... -
Control of estrous cycle and superovulation in goats
(2020-05-27)Summary Estrous cycle control is a widely used reproductive biotechnology for controlled breeding of small ruminants. Besides serving the purpose of synchronizing estrus, so that breeding takes place at a particular time, ... -
Einfluss von Haltung und Management auf das Tierwohl in der Milchviehhaltung
(2018-10-02)The main objective of this Phd-study was to examine the effect of different housing and management factors on the animal welfare level in dairy cattle. Therefore, 85 conventional dairy cattle farms were assessed using ... -
Einfluss des Weideangebotes auf Wohlbefinden, Gesundheit und Leistung von Milchkühen
(2018-03-05)The number of dairy cows with pasture access decreased considerably in the last years, especially in Europe where it declined between 2008 and 2012 by 17 percentage points to only 35%. In Germany, it must be assumed that ... -
Terminorientierte Besamung nach Presynch- oder Ovsynch-Behandlung sowie ein Vergleich verschiedener Methoden der Trächtigkeitsfeststellung bei Milchkühen
(2017-10-23)In dairy farming reproductive performance and milk yield of cows have a major impact on the operation’s economic success. As the negative correlation between milk yield and reproductive performance is widely known, the ... -
Studies on the Ascaridia galli embryonal stages, potential maternal protection and immune response in chicken
(2017-01-19)Regarding to a lack of experimental infection models and different maturation ability of Ascaridia galli egg sources (Worm uteri and faeces) in a first study (Paper 1), A.galli eggs isolated from two different sources ... -
Energy metabolism during long-term storage and subsequent thermal stress in liquid preserved boar spermatozoa
(2017-01-16)In major pork producing countries, artificial insemination is used in more than 90 % of breeding sows. Maintenance of good sperm quality during semen preservation is mandatory to ensure high fertility. Boar spermatozoa are ... -
Zusammenhang zwischen Bestands-, Gruppengröße und Indikatoren des Tierwohls in der konventionellen Schweinemast
(2016-04-25)Animal welfare became a significant issue in the society throughout the past decades. Many consumers tend to combine modern agricultural livestock farming primarily with a high number of animals on a confined space and ... -
Genetische Analyse von Verhaltensmerkmalen beim Schwein
(2016-01-12)This thesis deals with different behaviour parameters in pigs, which were measured during different production periods. The aims of the thesis were to investigate traits that characterise agonistic behaviour as well as ... -
Evaluation of non-invasive biomarkers for behaviour traits in beef and dairy cattle
(2015-02-03)This work investigates different non-invasive biomarkers for behaviour traits in beef and dairy cow. After a general introduction on behaviour tests, animal stress and biomarkers, the work is divided into three parts: In ... -
Attempts to promote the use of cryopreserved bovine semen: Effect of prostaglandin F2-alpha, sucrose and short-term dry ice storage
(2014-01-09)This dissertation argues that improvement of conception to artificial insemination (AI) through approaches that enhance post-thaw quality of bull semen might sustain enthusiasm for this technology and present a greater ... -
Untersuchungen von klimatischen Einflüssen auf die Gesundheit und Milchleistung von Milchkühen in Niedersachsen
(2013-07-30)Global warming will intensify heat stress for dairy cows. Particularly, heat stress affects animal welfare and health negatively. It is widely unknown to which extent different housing systems can alter this stress. ... -
Untersuchungen zur Erfassung und Genetik von Verhaltensmerkmalen beim Schwein unter Praxisbedingungen
(2013-07-24)Public and political concern for livestock increases and due to new laws housing systems of pigs will change in the future. It is desired to increase well-being of animals, for example, by group housing of pigs at the ... -
Untersuchungen zur Belastung von Schweinen bei langen Transporten
(2012-12-10)The legislative authority endeavours to keep animal transports as few and as short as possible with the help of additional requirements. However, animal trade in the EU and in non-European countries is increasing. Each ... -
Untersuchungen zur Bedeutung und Quantifizierung der Klauenqualität und Moderhinkeresistenz beim Schaf
(2012-02-17)The objectives of the present study were to determine the importance of footrot in Germany, Austria and Switzerland based on information of sheep farmers about prevalence, prophylactic and ... -
Untersuchungen zum Einfluss melktechnischer Parameter auf die Zitzenkondition von Milchkühen
(2011-06-08)Numerous studies deal with the effects of teat condition on mastitis matters. There is no doubt that pour teat condition increases the risk of mastitis. Studies that look at the interactions ... -
Investigations on the effects of dietary insoluble and soluble non-starch polysaccharides (NSP) on host-parasite interactions in laying hen chicks infected with Heterakis gallinarum or Ascaridia galli
(2011-05-11)The objective of this study was to test the hypothesis that low or highly soluble dietary non starch polysaccharides (NSP) differently affect infections with Heterakis gallinarum or Ascaridia ... -
