Untersuchung von Indikatoren zur Einschätzung des Risikos einer Subakuten Pansenazidose bei Milchkühen auf Praxisbetrieben
(2025-04-23)Feeding of high-yielding dairy cows in the beginning of lactation is a major challenge due to high energy requirements and reduced dry matter intake at the same time. This leads to diets with a high level of rapidly ... -
Understanding the Effective Number of Independent Chromosome Segments as a Tuning Parameter for Genomic Prediction
(2025-04-16)The effective number of independently segregating chromosome segments (𝑀𝑒) is a key parameter in animal selection. Its relevance lies within the methods to obtain the accuracy of genomic prediction. However, there is ... -
Housing pigs with undocked tails: methods for the early detection and prevention of tail biting
(2025-04-15)The occurrence of tail biting is a widespread problem in global pig farming. Painful biting incidents lead to a significant impairment of animal health, animal welfare and the performance of pigs in various production ... -
Application of imputed sequence-level genotypes to genomic analyses in German Warmblood horses
(2025-02-20)The use of whole-genome sequence (WGS) data in genomic applications is potentially superior to the commonly used genotype data from single nucleotide polymorphism (SNP) arrays, but their generation on a large scale is ... -
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 ... -
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 ...
