(2021-12-01)
In recent decades, Bangladesh’s economy has undergone a remarkable structural transformation. Agricultural wages are becoming high while staple food prices are becoming volatile. In the meantime, agriculture has experienced ...
Intestinal integrity characteristics of growing pigs in response to oregano essential oil supplementation
(2021-09-06)
The production of protein of animal origin is of great importance worldwide. In Germany, pig production is of considerable importance to meet this need. To ensure successful animal production, an intact intestinal tract ...
Evaluating rice performance in contrasting East African wetlands using an experimental and modelling approach
(2021-10-07)
Rice (Oryza spp.) has become an important staple food and cash crop across East Africa, and is now playing a pivotal role in regional food security and national economies. Since regional rice yields remain low, intensification ......
Reis (Oryza spp.) hat sich in ganz Ostafrika zu einem wichtigen Grundnahrungsmittel und Cash-Crop entwickelt und spielt heute eine zentrale Rolle für die regionale Ernährungssicherheit und Volkswirtschaften. Da ......

Glucocorticoid receptor-mediated responses to immune stress in pigs in the context of a natural gain-of-function substitution Ala610Val
(2022-01-07)
Despite the importance of glucocorticoids (GCs) and glucocorticoid receptor (GR) signaling, relevant knowledge in pigs is scant as compared to humans and model animals. This study aims to investigate the regulation, function, ...
Combining Fluorescence and Reflectance to Quantify Dynamics in Photosynthetic Regulation
(2021-12-14)
Photosynthesis in the field is anything but steady-state. Because environment is changing, understanding plant’s photosynthetic activity in situ is challenging. Measurement of solar-induced fluorescence (SIF), along with ......
Identification, characterisation, and evaluation of bioactive plant-based compounds for the sustainable stabilisation of food packaging materials
(2022-04-05)
Typically, plastic packaging materials are produced using additives, like e.g. stabilisers, to introduce specific desired properties into the material or, in case of stabilisers, to prolong the shelf life of such packaging ......
