Archaeologists Find Ancient Cheese Makers Used Tree Leaves to Boost Milk Production

By Doris Fleischer

A study published in Nature Ecology and Evolution sheds light on the innovative practices of Central Europe's early cheese makers.

Researchers at German Archaeological Institute (Berlin), University of Bristol, Museum National d'historie Naturelle (Paris) and Kiel University conducted and collated over 2,000 stable isotopic measurements of cattle teeth, bones, and pottery fats, revealing how pioneer farmers adapted their cattle herding techniques to the rich forested landscape of Central Europe.

Led by Dr. Rosalind Gillis from the German Archaeological Institute in Berlin, the study highlights an intriguing early practice: feeding cattle with leaves collected from trees during the summer to sustain them through the winter.

Video: Dr. David Rosero: Fat Quality in Swine Diets

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. David Rosero from Iowa State University explores the critical aspects of fat quality and oxidation in swine diets. He discusses how different types of lipids affect pig performance and provides actionable insights on managing lipid oxidation in feed mills. Don’t miss this episode—available on all major platforms.

Highlight quote: "Increasing levels of oxidized fats in swine diets reduced the efficiency of feed utilization, increased mortality, and led to more pigs being classified as culls, reducing the number of full-value pigs entering the finishing barns."

Meet the guest: Dr. David Rosero / davidrosero is an assistant professor of animal science at Iowa State University. His research program focuses on conducting applied research on swine nutrition and the practical application of smart farming. He previously served as the technical officer for The Hanor Company, overseeing nutrition, research, and innovation efforts.
