Managing dairy excreta as slurry can result in significant emissions of ammonia (NH3) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions …

The emission of greenhouse gasses is a trending subject worldwide. Also the maritime industry is looking for alternative options for zero-emission transport. Nedstack provides fuel cells as a solution for this challenge. This research is a first glance at the possibilities to create a feasible retrofit …

The present study investigated the effect of salt (NaCl) intake on urea-N excretion by using milk urea level as an indicator. Sixteen multi-parity Dutch dairy Holsteins (daily milk production 27.74 ± 3.14 kg and body weight 654.9 ± 43.1 kg) were used in a 4x4 crossover design with treatment varying in …
