Performance of underutilized forage legumes as an alternative to Trifolium repens under drought stress: yield, water utilization and nutritive value
(2013-05-31)Grassland with a high productivity and fodder quality forms the basis for ruminant nutrition. In grassland swards with no or little input of nitrogen (N) from mineral fertiliser or manure, legumes are essential for ... -
Genetic progress and inbreeding rate in complex breeding programmes – Applications to sport horses and laying hens
(2013-03-22)The main focus of this thesis is the optimization of breeding programmes. On the one hand a new method to account for the average inbreeding in the design of breeding programmes has been developed. On the other hand two ... -
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 ... -

(2012-06-26)Mycobacterium avium ssp. paratuberculosis (MAP) is the infectious agent of Johne -
Untersuchungen zu Auftreten von Clostridium botulinum, betriebsspezifischen Risikofaktoren und Symptomen beim Krankheitsbild des viszeralen Botulismus
(2012-04-27)Within a case-control-study influencing factors and typical symptoms were identified in order to detect and reduce the risk of this livestock disease. For these purposes a questionnaire was developed, which included three ... -
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 ... -
Milchproduktion in Deutschland und Europa nach der Liberalisierung - Abschätzung künftiger Entwicklungen mit unterschiedlichen analytischen Ansätzen
(2012-01-17)The liberalisation of the Common Agricultural Policy (CAP) is forcing dairy farmers and dairy processors to face national and international competition. Changes in the milk market are to ... -
Weaning and castration in beef calves
(2011-10-17)The present work included three trials to investigate the effects of abrupt separation on male and female beef calves of different ages (Trial 1; n=80) and the impact of the timing of this ... -
Variationen im Auslaufmanagement von Sportpferden in Einzelhaltung: Beurteilung der Auswirkungen auf die Tiergerechtheit an Hand des Tierverhaltens und der Stressbelastung
(2011-09-06)From an ethological point of view, the animal welfare in single housing systems must be evaluated critically. Without free exercise, scientists consider this system as not being suitable ... -

(2011-08-16)The aim of the first investigation was to devise an efficient protocol for getting a satisfactory embryo yield accomplished by combining the recently established ovsynch protocol with pFSH ... -
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 ... -
Untersuchungen verschiedener Einflussfaktoren auf Gesundheit und Produktivität beim Schaf
(2011-06-06)The breeding of healthy, resistant lambs with good weight gain is most important for shepherds. Basis for this is a good, natural breeding by the ewe, a gentle weaning method and a potential parasite resistance respectively ... -
