Exploring Two Different Feeding Strategies During Dry Period With Regard to Dry Matter Intake, Intermediary Metabolism and Certain Health Aspects of Dairy Cows in Germany

Journal of Animal Physiology and Animal Nutrition, Volume 109, Issue 5, Page 1073-1090, September 2025.
ABSTRACT Dry cow feeding plays an essential role in dairy production. Therefore, the objective of this study was to evaluate two different dry cow feeding strategies regarding dry matter intake (DMI), metabolism and health aspects of dairy cows in the first 50 days after calving.

Ist Phenylnitren ein fehlendes Bindeglied in der Bildung polyzyklischer aromatischer Stickstoffheterozyklen?

Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.
Ein neuer Bildungsweg für polyzyklische aromatische Stickstoffheterozyklen (PANH) wurde gefunden. Die Reaktion von Phenylnitren mit dem Propargylradikal führt zu Chinolin und belegt, dass Nitrene geeignete Vorläufer zum Einbau von Stickstoffheteroatomen sind.

On the Reduction of Ammonia from the Waste of Alpine Houses

Adsorption Science & Technology, 2005
An evaluation of the effectiveness of the cation-exchange resin Amberlite IR-120 (AMIR 120) for removing ammonia from aqueous solutions and waste was made. Two types of waste were obtained from houses located in the Alps and used in this work.
