The FUETURE project aims to efficiently utilize regional feed resources to reduce greenhouse gas emissions and improve energy efficiency in broiler chicken production. It seeks to develop an innovative approach based on the use of adaptable and resilient sustainably cultivated feed crops and previously underutilized domestic crops. Sustainability will be strengthened by reducing imports of unsustainable soy products from overseas. The scientific objective is to formulate regional feed rations taking into account sustainability criteria and the availability of co-products to reduce the environmental footprint of chicken meat. The environmental impact will be significantly reduced through innovative feed technology and precise supplementation of feed additives. The project aims to strengthen more sustainable regional food production and supports the German sustainability strategy.

PREGROW-project aims to provide a single nuclei transcriptional profile of the pituitary and its downstream targets in miniature-sized and larger-sized pigs as a model for prepubescent growth control. This approach is meant to meet a big challenge we encounter in research work on growth: Body size is a whole-organism phenotype with many different tissues involved, and the variant effects are expected to be complex. For this reason, PREGROW aims at studying the genetic landscape of growth-axis-related tissues in the pig, providing a genetic resource for deciphering mechanisms of gene interplay, and underlying variant effects. The objective is to perform a functional trait-cell type enrichment for previously identified genome-wide associated growth and height loci obtained from GWAS by assigning them to cell types identified in gene expression data on single nuclei level. The project aims at identifying those genes, which are differential in large versus miniature pigs, and can thereby be considered as important fine-regulators of prepubescent growth in pigs, in addition to the known hormonal axis regulation by growth hormone/IGF.

Antimicrobial resistance (AMR) is a global health threat that involves complex, opaque transmission
processes between humans, animals and the environment. The particular role of wildlife and the
environment in the emergence, maintenance, dissemination and transmission of AMR bacteria and AMR genes is widely unknown. In the MARRES project, AMR bacteria from grey and harbour seals of the North and Baltic Sea and of sea water (environmental - eDNA) will be determined to perform a targeted surveillance of these two marine ecosystems. State of the art microbiological techniques, genome and metagenome sequencing will be applied. The evaluation of published human and animal AMR data of the investigated areas as well as on a global scale shall put the obtained results from this almost unexplored field into a One Health context. The approach covers three One Health settings of marine ecosystems as one of the greatest players in Global Health. It promises to provide relevant insight into transmission pathways of AMR bacteria, including pathogens, and of AMR determinants between humans, wildlife and the environment. A database for AMR associated to marine mammals in the Baltic Sea will be established following the FAIR principles. On a longer term, this project should be the starting point to establish a transnational network between experts in the field of AMR and marine biologists in Europe. The implementation of a harmonized AMR surveillance in the marine ecosystem sector will significantly contribute to AMR mitigation strategies and thus to public health.

Project Details:
As part of the seal live monitoring program, harbour seals and other seal species are caught with nets in the Schleswig-Holstein Wadden Sea. In addition to staff from the University of Veterinary Medicine Hannover, Foundation, this campaign is carried out with the help of experienced staff from the State Office for Coastal and Nature Conservation, seal hunters and other helpers. The seals are measured (including blubber thickness via ultrasound) and weighed. Blood, hair and faecal samples as well as swabs for bacteriology and virology are taken. Based on the samples, blood counts are drawn up and blood chemistry, cytology, microbiology, virology and serology tests are carried out. Furthermore, tests for heavy metals (hair and blood) and persistent organic pollutants are performed.In addition, parasitological examinations for the detection and species identification of parasites as well as cytological and pathological processing of changes in the animal body are done. If grey seals are caught during the seal catches, the named examinations will also be carried out on them.
The examinations are carried out in cooperation with the Institute of Virology and the Institute of Pathology at the University of Veterinary Medicine Hannover, the Institute of Hygiene and Infectious Diseases at the Justus Liebig University Giessen, the Freshwater and OCeanic science Unit of reSearch (FOCUS) of the University of Liege (Belgium) and the department of Ecological Chemistry of the Helmholtz Centre for Environmental Research GmbH (UFZ) Leipzig. In addition to these investigations, seals are also equipped with telemetry devices as part of other research projects and doctoral theses.

Project Details:
With Alexa, Siri and Cortana, voice recognition and control software has become an integral part of our everyday lives. Animal voices also contain a huge number of information about the sender animal, such as species, identity, gender, age, body size, emotional state, diseases and hormone status. Bioacoustics therefore enables the development of non-invasive, time- and cost-efficient, automatic bioacoustic monitoring systems for animals. For this purpose, microphones can be installed recording animals' vocalisations around the clock without disturbing or influencing them. The recordings can be automatically analysed using mathematical algorithms to extract specific information. In addition, psychoacoustic tools can be used to elicit specific positive behaviours. Such bioacoustic tools can be used for clarification of taxonomic questions, to monitor wildlife as well as to improve animal husbandry and thus play an increasingly important role in species conservation and animal management. The aim of this project is to explore the wide range of possible applications and to develop bioacoustic monitoring systems for species conservation and animal management.

Few standardized studies are available on the effect of slow-release GnRH agonists in avian patients. With this background, the aim of this study is to examine the influence of deslorelin, a slow-release GnRH agonist, on the gonadal activity of female and male budgerigars in order to optimize the clinical use of this drug. The activity of the gonads will be examined, for example, by determining the sex hormones and by radiographic assessment of the reproductive organs.

The high-energy cosmic radiation has a decisive influence on all manned space missions. The effect of this radiation on the model organism Trichoplax adhaerens (Placozoa) will be investigated in this project. Placozoans are the most simply organized multicellular animals and can give us crucial clues about the effect of cosmic radiation on humans.
