Studies on the effect of exogenous amino acid application on nematodes
Blümel, Roman Christopher (2020-03-02)Plant parasitic nematodes are considered as key pathogens in agricultural crop production. They cause substantial yield losses in numerous crops and across all climatic regions worldwide. Antagonistic effects on various ... -
Use of Black Soldier Fly (Hermetia illucens) in bioconversion and feed production
Shumo, Marwa Abdel Hamid Ibrahim Hassan (2020-02-20)Population and economic growth, rapid urbanization and shifts in dietary preferences towards consuming more animal-derived products are some of the major challenges facing sub-Saharan Africa (SSA) today. Consequently, large ... -
Food Security Monitoring for Developing Countries in the Age of Big Data
Weber, Regine (2020-02-10)Approximately 817 million people are currently estimated to be undernourished and 85 million people across 46 countries are estimated to be in need of food emergency assistance over the course of 2019. Conflict, migration ... -
Active 3D Reconstruction for Mobile Robots
Palazzolo, Emanuele (2020-01-13)Mapping the environment with the purpose of building a 3D model that represents it, is traditionally achieved by trained personnel, using measuring equipment such as cameras or terrestrial laser scanners. This process is ... -
Acute impact of dietary pattern and walking on postprandial metabolism, attention, and mood in older adults with a cardiovascular disease risk phenotype
Diekmann, Christina (2020-01-27)Attenuating the postprandial stress response and its associated inflammatory and endothelial events through specific nutritional and lifestyle interventions seems to be a promising and important approach to decrease the ... -
In vitro and in vivo assessment of lead toxicity on mammalian female reproduction and effect of antioxidants
Aglan, Hoda Samir Badr (2020-03-17)Heavy metals are among the environmental toxicants incurring great concern for human and animals because of their toxicity even at low concentrations. Lead (Pb) has been shown to induce severe and long lasting effects on ... -
Effect of cow’s metabolic status on the epigenome profile of oocytes and embryos
Poirier, Mikhaël (2020-01-07)In lactating cows, intensive genetic selection for improved milk production has been associated with reduced reproductive capacity, leading to increased early embryo loss. During post-calving lactation, the cow’s dietary ... -
Influence of animal-specific factors on the quality and shelf life of fresh poultry and pork meat
Albrecht, Antonia (2019-12-12)The objective of this thesis was the assessment of the influence of animal-specific factors on typical quality parameters and shelf life of fresh poultry and pork meat. The trials comprised different study designs to analyze ... -
Homorhize und allorhize Wurzelsysteme: Vorfruchtwirkungen mehrjähriger Futterpflanzen auf die Ertragsbildung von Kulturpflanzen
Küpper, Paul Martin (2019-12-11)Seit dem Jahr 2007 wird ein mehrfaktorieller Feldversuch zu Früchtefolgen mit Feldfutterpflanzen auf dem Campus Klein-Altendorf nahe Bonn durchgeführt. Das Futter wird nicht geworben, sondern verbleibt nach Mulchschnitten ... -
Effects of pre-ensiling treatments on quality of lucerne silages, in vitro rumen fermentation and microbiota composition
Hartinger, Thomas Dietmar Said (2019-12-10)Lucerne (<em>Medicago sativa</em> L.) silages (LS) are commonly fed to ruminants. Due to substantial proteolysis during ensiling, the majority of crude protein (CP) in LS is non-protein nitrogen (NPN), which is rapidly ... -
Untersuchungen zur Wirtseignung toleranter Zuckerrübensorten für den Rübenzystennematoden Heterodera schachtii
Reuther, Marie (2019-12-10)Der Rübenzystennematode <em>Heterodera schachtii</em> ist der bedeutendste Schädling der Zuckerrübe. Anfällige Zuckerrübensorten zeigen eine hohe Wirtseignung für diesen Wurzelparasiten, sodass sich dieser besonders stark ... -
Consumption Choices: The effects of food production, markets and preferences on diets in India
Ludwig, Till (2019-12-20)The choice of which food to consume is often an individual choice. Yet, food and nutrition insecurity presents a situation that those who suffer from it have rarely chosen consciously. Availability of foods, their accessibility ... -
Transcription factors mediated oxidative stress response in bovine follicular cells and preimplantation embryos
Taqi Aboubakr, Mohamed Omar (2019-12-16)Transcription factors (TFs) are DNA-binding proteins implicated in regulation of gene activity and subsequently several biological functions under physiological, pathological and stress conditions. Oxidative stress can be ... -
Post calving metabolic status dependent changes on expression of extracellular vesicle coupled microRNAs in bovine follicular fluid and blood serum
Hagos, Tsige Hailay (2019-11-29)Most high yielding dairy cows enter a state of negative energy balance (NEB) during early lactation. This phenomenon is associated with disturbed metabolic status of the cows reflected in the blood and follicular fluid ... -
