Analysis for abundance estimates based on aerial survey data of harbour porpoises collected in the survey area " VIDAR"" in the Skagerrak"
Project Investigators: Prof. Prof h. c. Dr. Ursula Siebert; Dr. Anita Gilles
Duration: September 2024 until January 2025
Funding: Aarhus University, 5.291 EUR
Project Details:
For the surveys of the study area in the Skagerraö, densities and abundances of harbour porpoises were estimated and the inaccuracies (95% confidence intervals and coefficient of variation (CV)) associated with the estimation were determined. The processed data and results were submitted to the client.

Aerial Survey of grey seals in the Wadden Sea of Lower Saxony and Hamburg-2024/2025
Kegelrobben-Kartierung im Niedersächsischen und Hamburgischen Wattenmeer per Flugzeug 2024/25
Project Investigators: Prof. Prof. h. c. Dr. Ursula Siebert; Dr. Isabel Avila
Duration: Novemer 2024 until August 2025
Funding: Nationalparkverwaltung "Niedersächsisches Wattenmeer"", Virchowstr. 1, 26383 Wilhelmshaven", 39.722 EUR
Project Details:
The aim of the project is a survey of the local grey seal population in the entire Lower Saxony and Hamburg Wadden Sea during the birthing season (November-December) 2024 and at the time of the fur change (March-April) 2025.
On five trilaterally coordinated dates (three during the birthing season; two during the fur-change period), airborne surveys will be conducted with a single-engine aircraft. During the aerial surveys of the tidal flats, a high-resolution SLR camera will be used to photograph the haul-outs. In order to determine the number of young born as well as the total population, the photos taken are subsequently analyzed on the computer.

Development of a specific reference intervals for Fleckvieh bulls to assess their health, feed-intake as well as endocrine maturation
Erstellung von spezifischen Referenzbereichen zur Überprüfung des Gesundheits- und Versorgungsstatus sowie Abschätzung der endokrinen Reife von Bullen der Rasse Deutsches Fleckvieh
Project Investigators: Schmicke, Marion Prof.
Duration: December 2024 until December 2025
Funding: Karl-Eibl-Stiftung, 14.280 EUR
Project Details:
Ziel der Untersuchungen ist es, spezifische Referenzintervalle für Bullen der Rasse Deutsches Fleckvieh zu generieren. Hierbei sollen Proben aus der V. jugularis externa untersucht werden. Als Probenentnahmezeitpunkt wird die zweite Probengewinnung (vgl. EU VO 2020/686) frühestens 28 Tage (max. 30Tage) nach Einstallung und Beprobung des "letzten"" Tieres der Quarantäneeinheit herangezogen, die routinemäßig bei den Tieren aus seuchenhygienischen Gründen genommen wird. Dieser Zeitpunkt ist auch geeignet, um eine Aussage über die endokrine Reife und damit den Zeitpunkt für den Beginn der Spermaproduktion abzuschätzen. Die Werte sollen auch im Hinblick auf die Spermaquantität und -qualität der ersten Sprünge der Tiere ausgewertet werden, um spezifische Grenzbereiche zu etablieren für Bullen mit höherer versus schlechterer Spermaquantität bzw. -qualität."

Establishment and application of a model to study the post-mortem muscle-to-meat transition (ripening) of different slaughter species
Etablierung und Anwendung eines Modells zur Untersuchung der postmortalen Reifung von Fleisch verschiedener Schlachtspezies
Project Investigators: PD Dr. Carsten Krischek; Prof. Dr. Madeleine Plötz
Duration: January 2024 until December 2025
Funding: Drittmittelprojekt, gefördert durch Fritz-Ahrberg-Stiftung., 15.000 EUR
Project Details:
The precise investigation of the muscle-to-meat transition after the slaughter of farm animals is important, because it (could) lead to a better understanding of the processes during these post-mortem changes. This allows the definition and analysis of influencing factors that may have a positive or negative effect on the meat quality. However, since an in vivo analysis of meat formation is difficult to standardize, in vitro models have been developed that are easier to standardize with regard to metabolites/ compositions (e.g. certain organelles such as mitochondria). Since the models have so far been scientifically investigated in pigs and chickens, the study will first establish an already published in-vitro model with pig muscles and then transfer it to bovine and possibly turkey muscles. These models will then be used to analyze the physiological muscle-to-meat transition after slaughter in more detail, also taking into account certain exogenous and endogenous factors, especially the mitochondria. The influence of mitochondria will be examined in more detail, as they have an (important) influence on meat formation. In addition, the models will be used to analyze (pathological) problems in meat formation (e.g. PSE, DFD).

Effects of aerobic exercise training on epilepsies
Einfluss von aerobem Ausdauertraining auf Epilepsien
Project Investigators: Prof. Dr. M. Gernert
Duration: June 2023 until December 2025
Funding: Evangelisches Studienwerk Villigst, 44.500 EUR
Project Details:
Epilepsies are frequent neurological diseases in humans and dogs, characterized by recurrent, spontaneous seizures. About one third of human and two thirds of canine epilepsy patients do not become seizure free with the currently available antiseizure medications and are considered as pharmacoresistant. In addition, all antiseizure drugs cause adverse effects. Non-pharmacological treatment strategies are therefore urgently needed, and include therapeutic exercise training as adjunctive therapy.
So far, the effects of moderate exercise training on epileptic seizure thresholds are not sufficiently investigated, although several studies suggest that its positive effects might be therapeutically useful. Our pre-clinical studies focus on the effects of moderate exercise training on epileptic seizure thresholds and behavior.

Validation of the automated analysis of synovial cell count and corresponding reference ranges in cattle
Validierung der automatisierten Bestimmung des synovialen Zellgehaltes und entsprechender Referenzbereiche beim Rind
Project Investigators: Marion Schmicke; Maike Heppelmann; Johanna Hoischen
Duration: July 2023 until July 2025
Project Details:
The aim of this study is the validation of the automated analysis of cell count in bovine synovia using the ADVIA 2120i. Corresponding reference ranges for clinically normal joint aspirates should be developed to differentiate these from pathological samples. In addition, further examinations such as the determination of protein content and a microbiological examination of the samples are carried to analyse whether particular parameters can provide information on clinical appearance, diagnostics or therapy. Both macroscopically abnormal and normal joint aspirates are used for examination.

Immun-endocrine modulation on hepatocytes in vitro: Impact of cytokines on the expression of Insulin-like Growth-Factor Binding Proteins
Immun-endokrine Modulation am Hepatozyten in vitro: Einfluss von Zytokinen auf die Expression von Insulin-like Growth-Factor Binding Proteins
Project Investigators: Marion Schmicke; Schiffers, Christina; Schnieders, Christina
Duration: Mid 2023 until Mid 2025
Project Details:
The aim of this study is to analyse the effect of four distict cytokines, which are important in early bovine pregnancy, on the gene expression in cultured primary bovine hepatocytes. PCR is used to detect how the hepatocellular IGFBP-expression changes when the cells are stimulated with different cytokines in different concentrations. This demonstrates the connection between immunological and endocrine changes in early pregnant cows. We particularly focus on IFNτ, the embryonic pregnancy recognition signal of ruminants.
