Modeling and Optimization of Animal Breeding Programs
(2024-11-22)Simulation software can be used to model and optimize breeding programs. In the current work, the “Modular Breeding Program Simulator” (MoBPS) was applied to demonstrate this on three examples from layer, horse and pig ... -
Molecular Investigations on Spastic Paresis and Other Inheritable Bovine Diseases
(2024-10-30)Genetic mutations often cause serious diseases associated with severe animal suffering. Today, molecular methods enable efficient research and prevent spreading of disease alleles in cattle populations. The main objective ... -
Spirulina (Arthrospira platensis) als alternative Proteinquelle für Fische
(2022-11-16)The sustainability of livestock production is becoming increasingly important for consumers. Due to increasing levels of overfishing of the world's oceans, aquaculture has also been criti-cized for its role as the main ... -
Molekulargenetische und proteinanalytische Untersuchungen trächtigkeitsassoziierter Glykoproteine beim Rind
(2022-10-11)The dissertation addresses molecular genetic and protein analytical studies of bo-vine pregnancy-associated glycoproteins (boPAGs) and their practical application as pregnancy markers. Bovine PAGs are expressed by trophoblast ... -
Identification of molecular genetic causes of bull infertility
(2021-11-18)This is a cumulative thesis that includes three different topics around male infertility in cattle and canine diseases. Whole genome association analysis (GWAS) and whole genome sequencing (WGS), as well as additional ... -
Genetic Analysis of Dog Congenital Deafness and Herding Behavior
(2021-10-05)Strong artificial selections of canine morphological and behavioral traits lead to the formation of more than 400 modern dog (Canis familiaris, CFA) breeds within the past 300 years. Most dog breeds are derived from small ... -
On-site identification of animal species in meat products
(2021-07-12)The control of meat and its products is essential for sales and consumer protection. Due to personal preferences, but also religious and health reasons, the correct labelling is crucial. For meat species inspection, samples ... -
Vergleichende Analyse zweier Endstufeneberlinien unter besonderer Berücksichtigung des Geburtsgewichtes, in der Erzeugung von Ferkeln und Mastschweinen
(2021-07-07)The present dissertation compares two terminal sire lines based on the performance of their crossbred offspring under standardized environmental conditions along the entire production chain taking the birth weight into ... -
Genetische Analyse des bovinen bilateralen konvergenten Strabismus mit Exophthalmus des Holstein Rindes sowie der equinen hereditären Mikrophthalmie
(2021-06-24)In the context of the present thesis, two different hereditary diseases of the eyes were investigated. Bilateral convergent strabismus with exophthalmos (BCSE) in Holstein cattle and equine microphthalmia. The aim of the ... -
Construction of an equine antibody library in the single-chain-Fragment-variable format (scFv) to express equine immunoglobulins
(2021-03-30)Horses are exposed to a large variety of pathogens and diseases. Equine herpesvirus Type 1 (EHV-1) is one of the most prevalent viral pathogens infecting horses. Approximately 60 % of the horse population worldwide are ... -
Tierethische Positionen in der Gesellschaft - Eine empirische Analyse
(2021-03-05)The relationship between humans and animals has changed significantly over the last century, especially in Western countries. As a result, social demands for ethically correct treatment of animals have increased considerably. ... -
Untersuchung exogener Einflüsse auf den Reproduktionserfolg des Rindes unter Anwendung von In-vitro-Verfahren
(2020-06-03)This thesis deals with the analysis of various exogenous factors on the reproductive suc-cess of cattle by application of in vitro methods. Possible effects of semen type (conventional vs. female sexed) and calf ... -
High resolution differentiation of infectious agents at the level of antibody and nucleic acid by using peptide microarray and nanopore sequencing
(2019-08-09)In recent years, Point of Care (POCT) or Point of Need tests (PONT) have been established in order to provide accurate and rapid diagnostics directly at field level or at site of outbreaks. These assays can help decision ... -
Genomic and conventional evaluations for fertility traits in pigs
(2019-01-17)The aim of genomic selection (GS) is to predict breeding values with high accuracy for young animals (without own phenotypic record) as early as possible. GS can increase the accuracy of the breeding values at the time ... -
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 ...
