Project Details:
Thailand and Cambodia are both affected by malnutrition of children and mothers, be it by the by the sheer number of persons suffering from it (Thailand), be it by the high percentage of the general population (Cambodia). While consuming insects (entomophagy) has a long tradition in these countries and is relatively widespread, this tradition involves gathering from the wild and subsequent preparation and consumption of the fresh or frozen insects. On one hand, if food insects, because of their nutritional benefits, are to play a major role in providing food for mankind, farming rather than collecting from the wild will be necessary. These techniques, already practiced in some parts of Thailand and Cambodia, have the potential to be used as mini-livestock by families, as many insect species may be raised sustainably on agricultural side streams with less ecological impact as more typical livestock. On the other hand, rearing insects is prone to create surpluses in insect production, making preservation techniques necessary to ensure food safety by extending shelf life. These novel products may be produced for the family or sold at local markets creating an extra income.
IFNext attends these needs. The overall goal is to produce insects sustainably for the own consumption resp. to generate products that can be sold on the market and that actually meet the expectations of farmers and consumers alike.

Project Details:
Variation in biological traits is universal in natural populations and has significant evolutionary and ecological consequences. Behavioral traits or combinations of traits are important as they may affect the survival and reproductive success of individuals. Studies have shown that animal personalities and behavioral traits covary with ecological conditions, dependent on the state of the individual, and can be maintained by frequency dependent selection. Animal personalities have been often been classified along five behavioral axes, namely, shyness-boldness, exploration-avoidance, activity, aggressiveness, and sociability. Some studies have shown that amphibians display personality and behavioral traits. However, implications of animal personality in ecological context remain largely unexplored in amphibians. Neotropical poison frogs are toxic and diurnal amphibians with highly evolved parental care and territorial behavior. In this study, we will investigate behavioral traits and personality of the strawberry poison frog within and between populations that differ in their anti-predator strategy (level of aposematism). Therefore, we will examine variations in exploratory, risk-taking and aggressive behavior by running standardized laboratory-based trials on wild-caught adult O. pumilio. Each frog will be tested in three behavioral trials, with the following sequence: exploration, risk-taking and aggressiveness. Within a population, we expect individuals present variations in behavioral traits and personality, and that behavioral traits might be correlated (syndrome). Among populations we expect more aposematic frogs (brighter coloration, higher toxicity) to be more explorative, bold and aggressive than less aposematic frogs.

In der Vergangenheit sind zahlreiche Belastungstests beim Hund zum Einsatz gekommen. Hierbei handelt es sich meist um Adaptionen von Tests, die beim Menschen eingesetzt werden. Unter anderem wird in diversen Studien der 6-Minute-Walk-Test verwendet. Bei diesem Test wird die Strecke gemessen, die ein Patient im Rahmen von 6 Minuten zurücklegen kann. In einem Forschungsprojekt soll nun die Aussagekraft und Zuverlässigkeit dieses Tests mit der eines standardisierten, laufbandgestützten Belastungstests verglichen werden.

Die Aufzucht von aquatischen Organismen zur Gewinnung von Lebensmitteln in Kreislaufanlagen in Gebäuden an Land ist aus Gründen des Umweltschutzes (Vermeiden von Nährstoff-Eintrag in Gewässer) und Sicherstellung der Wasserversorgung der Aquakultur angesichts eines stark schwankenden Wasserangebots durch den Klimawandel dringend geboten. Allerdings ist die Technologie hinsichtlich Nachhaltigkeit und Tierwohl noch nicht ausgereift und daher verbesserungswürdig. Die relativ junge und in Europa noch wenig realisierte Biofloc-Technologie (BFT) bietet nach dem derzeitigen internationalen Stand der Kenntnis für die Zielstellung einer nachhaltigen Aquakultur ein bedeutendes Potenzial, das es zu entwickeln gilt. Das Potenzial von BFT-Systemen zur Umweltentlastung bei der Aufzucht von tropischen Riesengarnelen (Litopenaeus vannamei)besteht im Vergleich zu herkömmlichen Kreislaufanlagen darin, dass aus Detritus, Bakterienkolonien und kleinen Wirbellosen bestehende Bioflocken von Garnelen als Nahrung aufgenommen werden können und so zu einer Re-zirkulation von Nährstoffen (Stickstoff, Phosphor, organische Reststoffe), verbunden mit einem reduzierten Ressourceneinsatz (Wasser, Futtermittel), zu einer geringeren Freisetzung von eutrophierenden Stickstoff- und Phosphorverbindungen und letztlich zu einer erhöhten Biosicherheit und Produktivität bei einem niedrigeren spezifischen Energieverbrauch führen. Darüber hinaus kann die Verwendung von Bioflocken, die in ihrer Zusammensetzung der natürlichen Nahrung von Garnelen entsprechen, zu einer Verbesserung des Tierwohls durch verbesserte Fütterung führen.

Project Details:
Animals have become a core moral issue in Western societies. All those who earn their money from animals should be able to think through their position and present it in a well-considered manner. However, the experiences of recent years also show how relatively quiet the voices from agriculture are in an ever louder concert on this topic. In this sense, a solid project on ethics in livestock farming serves the purpose of self-positioning internally and the ability to engage in discourse externally. The basis of the project is to be a well-founded, applied ethical analysis of the current debate on animal husbandry, from which a handbook will be centrally produced.

Results:

EthOrNu should offer "ethical orientation for livestock farming" in several respects: It should make the moral discourses in society more understandable for those involved who earn their money from livestock farming, and at the same time create an offer to position themselves in these discourses. Conversely, it is intended to open up relevant agricultural expertise for those interested in ethical issues and to help them make informed judgments about animal husbandry. The novelty lies in this bridge, which can be crossed from both sides. Only by combining both elements is it possible to make a competent assessment of the real and concrete conditions in livestock farming. The central building block for this is the creation of a handbook that presents relevant knowledge in an attractive way for both sides and opens up the possibility of further use. From the handbook, it will be possible to develop materials that also make the results accessible for the specific (initial, further and continuing) training of livestock farmers. Furthermore, central contents and theses from the project were tested in the field, e.g. in a larger presentation of the "decision cascade" at the Animal Welfare Day in Triesdorf (April 2022). The collaboration with the "Responsibility of advisors in livestock farming" project also made it possible to discuss the key ethical content of the handbook with a highly interesting target group, namely agricultural advisors, at several workshops.
