Risk based approach towards more sustainability in European pig production
(2013-02-20)
Major aim of this thesis was to demonstrate how the use of a HACCP concept, a risk based approach, improves the sustainability of added value chains in European pig production. The thesis is featured as a pseudo-cumulative ...
Morphological reflectors and molecular predictors of preimplantation developmental competence in bovine oocytes and embryos
(2013-03-27)
The efficiency of in vitro production (IVP) of bovine embryos still remains low, reaching blastocyst rates between 25 and 35 %. Accordingly, the necessity to define reliable predictors for developmental competence is ......

Effects of 137Cs and 90Sr on structure and functional aspects of the microflora in agricultural used soils
(2013-03-01)
At long sight 137Cs and 90Sr are the main radionuclides responsible for the contamination of agricultural soils due to core melts in nuclear power plants such as Chernobyl or Fukushima. Once deposited ...
Compost and residues from biogas plant as potting substrates for salt-tolerant and salt-sensitive plants
(2013-01-10)
Compost and residues from biogas plant have been increasingly recognized as potting substrates in horticulture. To investigate the suitability of both materials to grow salt tolerant plants in 2010 a pot experiment was ...
Nutrient recycling from animal slurries: Solutions for minimizing eutrophication and environmental pollution
(2013-11-21)
Economic development with a concomitant higher income as in China is often associated with a growing demand for protein rich food. This has led to high animal densities, especially large pig farms and consequently vast ...
Erfassung der Wurzelarchitektur von Zuckerrüben und Mangold mittels UWB-RADAR
(2013-09-27)
Die Züchtung von Nutzpflanzen ist ein wichtiger Prozess für die Entwicklung leistungsfähiger neuer Pflanzensorten. Die schnelle Bonitur einer Vielzahl von Nutzpflanzen im Rahmen einer pflanzenzüchterischen Fragestellung ...

Deposits of foliar-applied herbicides: characterization and relevance for bio-efficacy as evaluated in selected weed species
(2013-10-07)
The main focus is to elucidate and characterize the effect of formulation on the deposition patterns and the consequences for the foliar uptake of herbicides, either through cuticular or stomatal pathways. Glyphosate (Gly) ...
EU wide analysis of the Common Agricultural Policy using spatially disaggregated data
(2013-10-17)
Recent reforms of the Common Agricultural Policy shifted the emphasis towards competitiveness of the agricultural sector, rural development and environmentally sound farming approaches, acknowledging the considerable role ...
Energy and nitrogen use efficiency in farm animal nutrition – opportunities and limitations for improvement
(2013-09-09)
This thesis combines three different topics that are seemingly unconnected but inherently linked. The first part deals intensively with co-products from biofuel production on a European level. There are numerous co-products ......
