Behaviour and performance of growing and finishing pigs depending on different housing conditions and sire breeds
(2022-10-11)Conventional pig farmers and more particularly their pigs face many challenges throughout different production stages that can alter the welfare and health of the animals and impair the farmers economy and motivation ... -
Indicator-based flock management in broilers and turkeys – mortality, foot pad health and environmental factors
(2020-12-21)For a long time, animal husbandry systems were evaluated with resource-based indicators like space per bird or measures of barn equipment. In favor of animal-based indicators the use of those evaluation systems were declined ... -
Molekulargenetische Analysen fortpflanzungsrelevanter Fragestellungen beim landwirtschaftlichen Nutztier
(2018-12-04)This dissertation addresses two topics that are relevant for the reproduction of live-stock. The first part of the thesis describes genetic and environmental factors influenc-ing sperm quality in ejaculates of artificial ... -
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 ... -
A step to reducing tail biting in finisher pigs: Can a management tool help pigs and farmers?
(2014-12-16)Tail biting is a major welfare and economic problem in pig production which is difficult to prevent on conventional farms due to its multifactorial nature. A wide range of risk factors have already been identified, but a ... -
Entwicklung und Validierung von praxistauglichen Maßnahmen zum Verzicht des routinemäßigen Schwänzekupierens beim Schwein in der konventionellen Mast
(2014-08-26)Most of the piglets get their tails docked during the first days of living in order to prevent or at least minimize the occurrence of tail biting in pigs. This routine practice of docking is not in accordance with the ... -
Response to disturbance and plant-animal interactions of grassland swards for chicken free-range husbandry
(2013-08-27)The aim of the present study was to evaluate the suitability of fourteen grassland plant species for establishing swards for free-range chicken husbandry. Nine grasses and five forbs which are known for their good performance ... -
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 ... -
Dissection of molecular basis on a causative mutation for ear size QTL on chromosome 7 in pigs
(2013-07-15)The pinna，an important component of the external ear, first appeared in mammals. It plays a vital role in collecting sounds, radiating heat and signaling mood. In humans, the most common ear defect is microtia with prevalence ... -
Estimation of Genetic Parameters and Evaluation of Breeding Program Designs with a Focus on Dairy Cattle in Low Input Production Systems
(2013-07-15)Due to restrictions on feeding and management on low input farms, there are vast differences between cattle on low input and conventional farms. Therefore, variance components of the same traits recorded in low input and ... -
Pregnancy-associated glycoprotein (PAG) profiles in cows and goats and attempts to measure PAG in milk
(2013-07-09)The aim of the PhD dissertation was to examine the reliability of a PAG polyclonal ELISA developed by Friedrich and Holtz (2010) in goats, different cattle breeds and bovine milk. The dissertation comprised three studies. ... -
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 ... -
Behaviour, interactions and habitat use of European bison (Bison bonasus), Exmoor ponies (Equus ferus) and Dybowski deer (Cervus nippon hortulorum) in a mixed-species enclosure at Tierpark Sababurg
(2013-05-14)From spring 2010 to early summer 2011, the behaviour, intra- and interspecific interactions, as well as the habitat use of European bison (Bison bonasus), Exmoor ponies (Equus ferus) and Dybowski deer (Cervus nippon ... -
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 ... -
