Arie Kies

Arie Kies is an external employee specializing in Animal Nutrition with significant contributions to research on protein digestion and metabolism in livestock. Their work primarily focuses on pig and poultry nutrition systems, with extensive publications in leading animal science journals.

Research interests center on protein fermentation dynamics, digesta flow, and amino acid metabolism in monogastric animals. Key areas include:

• Digesta analysis and flow measurement
• Protein fermentation in the hindgut
• Broiler chicken nutrition optimization
• Comparative digestion between pigs and humans
• Effects of protein sources on gut health
• Endogenous protein losses and metabolism

Recent publication trends show consistent high-quality output with multiple 2025 publications examining protein fermentation potential across different protein sources and animal models. The research demonstrates strong methodological rigor with both in vivo and in vitro approaches, particularly focusing on how dietary protein characteristics affect digestive processes and animal performance.

Arie Kies actively contributes to the academic community through conference presentations and PhD supervision. Notable activities include keynote presentations on vitamin nutrition (April 2022) and steering protein fermentation research (April 2024), plus chairing the 5th International Conference on Responsible Use of Antibiotics in Animals (June 2021).

Current research projects include:

• 'Consumer preference driven optimization of efficient pork production in China' (as co-promotor since May 2023)
• 'Dynamics of proteolytic fermentation and the effects on intestinal health of broilers' (completed May 2023 after 6.5 years as co-promotor)
