On July 8th my colleagues and I discussed “The Essential Societal Role of Livestock, Today and Tomorrow” for the Livestock Symposium at the 2025 Meeting of the American & Canadian Societies of Animal Science in Hollywood, FL.
The presentations were recorded and videos are now available.
Knowing your presentation is not the same thing as knowing your subject.
Last week at Miami University, technology took away my speaker notes—and conversations caused me to substantially rewrite the lecture I'd come to give.
Some reflections on preparation, assumptions, scientific models, and following connections: ruminati.substack.com/p/foll…

"Milk, yogurt, and especially cheese with its rich culinary history are integral components of the French diet. Dairy foods provide affordable nutrient density and have a relatively low impact on the environment"

"Meat and other animal-sourced foods provide crucial nutrients that support the growth and development of children, maintain muscle mass and function in adults, and help mitigate several chronic diseases, such as those associated with aging and obesity" frontiersin.org/journals/nut…

People assume "lab meat" looks like a ribeye coming straight out of a Petri dish.
Not. The only commercial product is an overpriced fake "chicken" nugget with only 3% cultured fibroblast cells, bulked up with oil, starch, and soy.
Not gonna happen. Don't believe the hype.
A mixed grill this week:
• Bretz & the Channeled Scablands
• My upcoming Miami Univ. Willeke Lecture
• Metabolic Mind
• AMSA RMC Exchange Live
• Metabolic Health Conference 4.0 in India
• Protein, carbohydrates—and a question we don't ask enough: Where will the fat come from?

Rangelands & pastoralists sustain food production, livelihoods, cultures & economies.
Yet they face growing pressures from land conversion & limited decision-making power.
Here are 6️⃣ ways governments & policymakers can support them.

Pastoralists herd about 1 billion animals worldwide.
They support food security, safeguard biodiversity, strengthen climate resilience and preserve cultural heritage.

"Long-term vegetarian and vegan diets in older adults were associated with inadequate micronutrient intake [Ca, Zn, Fe, vit B9, B12, D] and insufficient protein intake and quality [83% vegans and 40% vegetarians were below RDA], especially in vegans"

Animal-sourced foods are often framed as a problem for human health and the planet. 🐄
@bschermd speaks with @GrassBased about livestock, malnutrition, chronic disease, and why restoring metabolic health may require a broader nutrition and sustainability conversation.

Rumen and hepatic biotransformation of plant metabolites contribute to differences between grass- and grain-fed beef
Grass-finishing: more phenolic-derived metabolites & vitamin E
Grain-finishing: more B₁, B₅, B₆
Pasture-finishing enhances phytonutrients and fat-soluble vitamin profiles while grain-finishing enhances B-vitamins in beef from North American commercial operations sciencedirect.com/science/ar…
