Manure Evaluation: Cows and Their Rations LIVE with Dr. Mary Beth Hall and Dr. Stefano Vandoni
This episode of the Real Science Exchange features Dr. Mary Beth Hall, founder of The Cows Are Always Right and former USDA‑ARS scientist, discussing her highly attended Real Science Exchange webinar, Manure Evaluation: Figuring Out What’s Going On Between Cows and Their Rations. Joining the pub‑table conversation are Dr. Clay Zimmerman, Dr. Stefano Vandoni, and Dr. Sion Richards. Dr. Mary Beth Hall explains why manure evaluation is one of the most reliable diagnostic tools in dairy nutrition, providing a direct biological response that may not appear in ration models or performance data. She emphasizes why manure must be evaluated alongside cow behavior and production metrics. Mary Beth breaks down the science of fecal pH, including how to measure it correctly, why results can be misleading if done improperly, and what fecal pH reveals about digestion beyond the rumen. She explains why fecal pH does not directly reflect rumen pH and how fiber source influences hindgut fermentation. The discussion shifts to practical manure screening on farm. Mary Beth explains what to look for when rinsing manure, how undigested fiber or grain can signal rate‑of‑passage and feed processing issues, and why screening is best used as a qualitative diagnostic tool rather than a strict numerical benchmark. The panel compares manure evaluation with rumination monitors and emerging dairy technologies, highlighting why sensor data must be interpreted in context with manure consistency, cow behavior, intake patterns, and diet composition to accurately assess cow health. Real‑world troubleshooting examples illustrate how ration and management issues—including spoiled silage, feed sorting, inconsistent intake, and water quality problems—often appear first in the manure. Variation within a pen is discussed as an early warning sign for nutrition challenges. In closing, the group reinforces why manure evaluation remains underutilized despite being one of the clearest biological indicators of cow health. Integrating manure observation with cow comfort, rumination, feeding management, and overall herd behavior is critical for better nutrition decision‑making.
