In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Marcos Marcondes from the William H. Miner Agricultural Research Institute discusses key insights into calf and heifer nutrition. He shares findings on feed intake modeling, pre- and post-weaning transitions, and how feeding strategies influence mammary gland development and long-term milk yield. Listen now on all major platforms!

"Pushing heifers to calve too early reduces milk production, even when body weight is adequate; mammary development needs time."
