The Dairy Nutrition Blackbelt Podcast

In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Victoria Asselstine from Jefo Nutrition and Dr. Mélissa Duplessis, research scientist at Agriculture and Agri-Food Canada, discuss B-vitamin nutrition in modern dairy cows. They explain why older assumptions about rumen synthesis may not fully match today’s production demands, how transition cows rely on B vitamins for protein and energy metabolism, and why regional diet differences can influence folate and B12 status. Listen now on all major platforms! "Dairy cows are now producing more milk, and their nutrient needs have increased accordingly, including B vitamins." Meet the guests: Dr. Victoria Asselstine https://www.linkedin.com/in/victoria-asselstine/ earned her Ph.D. in Animal Genetics and Immunology from the University of Guelph and serves as Ruminant Technical Service Manager at Jefo Nutrition. She collaborates with industry and academic partners to evaluate nutritional strategies supporting transition cow health, calf development, productivity, and sustainability. Dr. Mélissa Duplessis is a Research Scientist at Agriculture and Agri-Food Canada.

In this episode of The Dairy Nutrition Blackbelt Podcast, Brittany Herzfeldt, Microbiology Nutritionist/Consultant at Priority IAC, discusses forage quality through the lens of usable fiber, moisture, lignin, chop length, and rumen fermentation. She explains why early, wetter forage harvests can improve digestibility, how excess lactic acid can create acidosis pressure, and why targeted bacteria can help cows utilize highly available diets more effectively. Listen now on all major platforms! "We want the most dense forages and grains. We do not want to fill the cow up with anything that she cannot use." Meet the guest: Brittany Herzfeldt https://www.linkedin.com/in/brittany-herzfeldt-50816a236/ is a Microbiology Nutritionist and Consultant at Priority IAC, working with dairy producers across the United States.
