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 ......
