Stefan Yerby

Stefan Yerby is a researcher focusing on ruminant environmental sustainability and enzymatic applications in livestock production. His work is supervised by Dr. Michelle Bellingham and Professor Nicholas Jonsson. Key research topics include rumen fermentation kinetics, exogenous enzymes for dairy calves, and the use of Aspergillus niger in feed optimization.

His research interests revolve around improving dairy cattle nutrition through biotechnological interventions and understanding the environmental impacts of ruminant husbandry. Recent studies emphasize solid-state fermentation products and their effects on feed degradation and rumen microbiology.

Articles published in 2024–2025 highlight themes like enzyme efficacy in calves, in vitro rumen fermentation dynamics, and in sacco degradation analysis. These studies contribute to sustainable livestock practices and feed efficiency optimization.

No scientific awards or grants are listed, and no advising relationships are explicitly mentioned. Collaborations with Prof. Jonsson and others suggest involvement in academic research teams focused on agricultural biotechnology.
