Laying hen welfare -The prevention of feather pecking and keel bone damage
(2019-05)
Feather pecking (FP) and keel bone damage (KBD) are important animal welfare problems in laying hen housing, in both organic and conventional systems.
This PhD project aimed (1) to give an overview over results from scientific studies regarding factors with preventive effects on FP, and on the extent practice recommendations are based on this scientific evidence; (2) to identify further influencing factors on FP and to test the significance of the extent of compliance with recommendations; and finally (3) to discover ...

Natural and land-use drivers of primary production in a highly vulnerable region of livestock production (Sierras del Este – Uruguay)
(2019-02-21)
Sierras del Este is one of the two regions in Uruguay that are most vulnerable to climate change. A relevant vulnerability factor is the variability of the natural grasslands’ productivity. The objective of this study was to analyse the role of natural and land use drivers on grassland productivity as an essential factor for increasing the adaptive capacity of livestock production and reducing their vulnerability to extreme climatic events. The period 2000–2015 was analysed using the aboveground net primary production ...

Machines as teammates: A research agenda on AI in team collaboration
(2019-07-06)
What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. ...

Quality of black bean seeds harvested with different moisture contents and submitted to two different storage systems
(2019-12-05)
Bean (Phaseolus vulgaris L.) is one of the main foods of the Brazilian diet. However, to achieve high yields, one of the determining factors is seed quality, which can be influenced by harvesting time and storage. The objective of this work was to evaluate the physical quality and physiological performance of black bean seeds as function of the moisture content at harvest and storage method. For that, black bean seeds, cultivar BRS Campeiro, were used. The harvest was performed when the seeds reached moisture contents ...

A sequence analysis of organic and conventional food consumers’ visual information acquisition
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-07-26)
It is of significant importance in food marketing to know which pieces of information available during shopping are most relevant to consumers. The visual search behaviour of consumers allows inference on the relevance of information based on what information is acquired and when. It is assumed that price is a major barrier to the purchase of organic food. However, little is known about consumers’ actual acquisition of information on organic food prices. To examine the information acquisition behaviour of consumers ...

Identification of individuals and groups in a public goods experiment
(2019-07-03)
Revealing the identities of contributors has been shown to increase cooperation in public goods games. In this paper we experimentally investigate whether this finding holds true when decisions are made by groups rather than individuals. We distinguish between groups in which members can discuss face-to-face to reach a decision and groups in which members communicate via computer chat. The results confirm the positive effect of identification on cooperation among individuals. For groups, however, we only find a small ...

Assessment of a pragmatic strategy to improve health of kacang goats in subsistence agricultural communities in Indonesian Borneo
(2019-11-22)
Poverty limits options available to smallholder, subsistence farmers to prevent or reverse livestock malnutrition and endoparasitism, two of the global drivers of goat morbidity and mortality in resource-constrained, tropical, agricultural communities. Our first study objectives describe changes observed in body condition and anaemia after implementation of three feasible and simple husbandry changes to improve health of smallholder herds of kacang goats in rural, Indonesian Borneo. These changes included routine ...
