Process Engineering in Animal Production

The main topics of research and teaching in livestock technology range from supply systems (for feed, water, and air) to the environmentally sound management of by-products, particularly liquid manure and exhaust air. Technical development focuses on animal-friendly housing conditions (such as resting, walking, feeding) and product extraction (e.g. milking). The goals of these technological innovations are to improve animal welfare, enhance the efficient use of resources, and reduce environmental impacts. The Faculty of Agriculture, Food and Nutritional Sciences, and Engineering at the University of Bonn has long played a leading role in scientific research on livestock farming in Germany. The knowledge and insights gained from this research are integrated into the academic programs and passed on to students in subject-specific degree courses. Particular emphasis is placed on incorporating the findings of current research projects into teaching. The digitalization of livestock farming ("Precision Livestock Farming"), sensor-based monitoring and computer-aided analysis of animal behavior, as well as conclusions regarding animal welfare, are also key elements of both research and teaching.

The Faculty of Agriculture, Food and Nutritional Sciences, and Engineering at the University of Bonn operates three external research stations that serve as practice-oriented sites:

  • Campus Frankenforst, focusing on livestock farming and precision livestock farming,
  • Campus Klein-Altendorf, serving as a center for crop production and agroecosystem research, and
  • Campus Wiesengut, specializing in organic agriculture and sustainability.

These locations enable a close integration of scientific research and practical application.

Our research combines innovation with practical relevance to promote sustainable agriculture. The key areas include environmental and climate protection, the advancement of animal welfare through modern technologies, and the optimization of feed quality and preservation.

With forward-looking approaches, we contribute to the development of a resource-efficient and competitive agricultural sector.

Will we still keep pigs in the future?

From 5 to 7 February 2025, the VLF National Seminar for Pig Farmers took place at Hofgut Neumühle. Prof. Dr Wolfgang Büscher was invited as a speaker and gave two specialist presentations on current and future issues in pig farming.

In his first presentation, he outlined possible applications of artificial intelligence in pig farms and discussed its potential for animal monitoring, management and improving efficiency. The second presentation focused on energy supply for agricultural holdings using photovoltaic systems, in particular the use of battery buffers to stabilise and optimise self-consumption.

The seminar provided a valuable platform for dialogue between academia and industry.

Dr Hauke Deeken receives the German Maize Committee’s award

Dr Hauke Ferdinand Deeken was awarded the German Maize Committee (DMK) Encouragement Prize for his doctoral thesis. The thesis, entitled “Environmental impacts of silage production: Formation, emission and fixation of gases from field to barn”, examines the emission processes throughout the entire silage production chain – from the field to the barn.

Since 1998, the DMK has been honouring authors of exceptional, practice-oriented scientific works relating to maize cultivation. The doctoral thesis was completed at the Institute of Agricultural Engineering at the University of Bonn, within the Chair of Animal Husbandry Technology (Prof. Dr Wolfgang Büscher), in the Forage Preservation research group. The award ceremony takes place annually as part of the DMK Annual Conference in mid-November.

The award specifically recognises the scientific relevance and practical application of the research into reducing emissions in silage production.

Presentation at the USPLF Conference  in Nebraska

From 2 to 5 June 2025, Dr Jessica Paßmann and Ms Diana Nett attended the United States Precision Livestock Farming (USPLF) Conference in Lincoln, Nebraska. Both presented the latest research findings on emissions from dairy farming.

Dr Paßmann presented the TUI barn under the title “TUI Barn: An integrated approach to emissions, animal welfare and system synergies”. The project centres on a modular research barn in which the interactions between animal welfare, the environment and husbandry techniques are investigated under realistic conditions.

Ms Nett gave a presentation entitled “Long-term investigations of ammonia emissions from slatted floors in dairy barns with rubber inserts and emission protection flaps”. The focus was on long-term measurements aimed at reducing ammonia emissions through technical modifications.

The international conference provided an excellent opportunity for scientific exchange and networking with colleagues specialising in precision livestock farming. The University of Bonn’s research was thus also represented on the international stage.
