Organization and transcription analyses of the immunoglobulin genes in cattle and horses
(2016-06-10)Initial studies on genetic aspects of immunoglobulins were performed on humans and mice but were successfully applied to various other animals such as chicken, rabbit, swine, cattle, and horses, too. Especially in cattle ... -
Application of selection index theory comprising genomic information to breeding programs of sport horses and pigs
(2013-12-17)This thesis presents three model calculations based on selection index theory to evaluate the benefit of genomic information for the optimization of current breeding strategies in sport horses and pigs. In chapter one, an ... -
Accuracy of Genomic Prediction in Dairy Cattle
(2013-12-06)Prediction of genomic breeding values has become a popular tool for obtaining reliable breeding values of animals without phenotypic information, especially in dairy cattle breeding. The main focus of this thesis was to ... -
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 ... -
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 ... -
Evaluation of the immunological status in clinically healthy and subclinically infected bovine mammary glands
(2013-02-26)Mastitis is a major disease affecting dairy cattle worldwide. Especially the subclinical form of the disease causes high economic losses. The evaluation of udder health is based on somatic cell count (SCC) and bacteriological ... -
Quantitative and molecular genetic studies on temperature-dependent sex determination of Nile tilapia (<i>Oreochromis niloticus</i>)
(2012-06-13)Tilapia is one of the most important species group for aquaculture production. Particularly Nile tilapia (Oreochromis niloticus) amounts to over 80 % of the world tilapia production. All-male populations are favourable due ... -
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 ... -
Detection of new allotypic variants of bovine antibody λ-light chain and IgG-heavy chain constant regions
(2012-02-15)In the cattle breeds German Black Pied (GBP), German Simmental (GS), Holstein Friesian (HF) and Aubrac (A) the transcribed λ-light chain (IGλ) and the IgG heavy immunoglobulin chains (IgG) ...
