Untersuchungen zum Nährstoffkreislauf, zur Leistung des Grünlands und der Rinder bei Nährstoff-extensiver Mutterkuhhaltung und ausschließlicher Grünlandnutzung im Mittelgebirge
(2005)
Seit Einführung der Milchquotenregelung im Jahre 1984 ist die Anzahl der Mutterkühe deutlich angestiegen. Mutterkuhhaltung gilt allgemein als ökologisch vorteilhafte Form der Rinderhaltung. Zum Nährstoffkreislauf und zu ...
Untersuchungen zur O-GlcNAc-Glykosylierung von Proteinen aus Endothel- und Skelettmuskelzellen
(2010-12-22)
Die O-GlcNAcylierung ist eine Ernährungs- und Stress-sensible Proteinmodifikation, welche eine Vielzahl regulatorischer Funktionen in zellulären Prozessen, wie Transkription, Signaltransduktion und Stoffwechsel, ausübt. ...
Crop management options to reduce nitrogen pollution in Liangzihu lake basin, Central China
(2015-06-18)
In Central China, high mineral nitrogen (N) application rates lead to low N recovery and high N losses. Large amounts of the nitrate-N leached from agricultural soil end up in aquatic ecosystems, which negatively affects ...
Large-scale mass redistribution in the Earth system from synergistic use of Swarm data
(2022-01-26)
Long and consistent time series of large-scale mass redistribution in the Earth system are important in many scientific research areas. The dedicated Gravity Recovery And Climate Experiment (GRACE) and Gravity Recovery And ...
Resilience, collapse and reorganization of a rangeland socio-ecological system in South Africa
(2016-05-24)
Communal rangelands in semi-arid areas are complex socio-ecological systems (SES). Their complexity arises from non-linear feedbacks between the social- and the ecosystem. To understand the social system requires tackling ...
Epigenetic regulation of CD14 in TRIF pathway in pulmonary alveolar macrophages of German Landrace pigs
(2016-05-24)
Diseases of the respiratory system are a main problem in pig production. Pulmonary alveolar macrophages (PAMs) are key players to defend these respiratory diseases like lung inflammation caused by bacterial infection. ...
Systems biology analysis of meat quality in Duroc × Pietrain pigs based on integrated omics approaches
(2017-07-03)
Water holding capacity and drip loss are important commercially interesting meat quality parameters with low heritabilities and complex genetic and metabolic background. The aim of this thesis was the application of different ...
Conceptualising and estimating rationalised agricultural optimisation models
(2018-07-19)
Computational modelling for quantitative agricultural policy assessment in the EU employs more farm level oriented approaches in recent years. This follows policy instruments that increasingly target the farm level and ...
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
(2020-03-03)
In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ...
Food waste reduction concepts for stakeholders in the food supply chain and auxiliary organizations
(2019-09-10)
The objective of this thesis was to develop concepts to support the reduction of food waste in the food sector. The concepts are targeted to private companies, such as manufacturing businesses, retailers, and large-scale ...
