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

Nov 13, 2024

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: PRRS Eradication Strategies - Dr. DeBuse and Dr. Tousignant

In this episode of The Swine it Podcast Show, Dr. Neil DeBuse from Kalmbach Feeds and Dr. Steve Tousignant from Vaxxinova US discuss PRRS management strategies, recombination risks, whole genome sequencing, and the role of autogenous immunization programs in swine systems. They highlight practical approaches to improving immunity, reducing outbreaks, and advancing PRRS control across production systems. Listen now on all major platforms!

"Being PRRS negative sooner is a real key for eradication because every additional positive week increases production losses and viral exposure risks." - Dr. Neil DeBuse

Meet the guest: Dr. Neil DeBuse is a veterinarian at Kalmbach Feeds with more than 30 years of experience in swine health and production. His work focuses on PRRS control, biosecurity, immunity, and improving production stability across commercial swine systems in the United States and internationally.

Dr. Steve Tousignant is Director of the Swine Business Unit and Technical Services Veterinarian at Vaxxinova US, with a DVM and PhD from the University of Minnesota. His experience combines epidemiology, technical services, and practical immunization strategies designed to support consistent herd performance and long-term production stability.
