NRC Series: Feed Intake & Carbohydrates

NRC Series: Feed Intake & Carbohydrates

Author: Balchem Animal Nutrition & Health November 3, 2021 Duration: 1:06:00

Guests: 
Dr. Mary Beth Hall with the USDA
Dr. Paul Kononoff from the University of Nebraska-Lincoln
Co-host: Dr. Clay Zimmerman, Balchem

We continue our discussions on the new 2021 dairy NRC, now known as NASEM. This is a follow-up to our Real Science Lecture series of five webinars that officially unveiled the content back in September. We’ll be breaking down the feed intake and carbohydrates sections during this episode.

Dr. Mary Beth Hall discusses the changes in the dry matter intake equations in the new NASEM. She explains that there are two different dry matter intake equations, and those equations have new factors that give producers a much closer look at the diet and what factors will influence intake. (7:29)

Dr. Paul Kononoff discusses the new feed factor equations and using different forage decisions. He explains when using it for forages, the new equation will be very useful to producers especially with all the factors involved. He also discusses byproducts and his hope for them to be included for future equations once more research is done. (26:19)

Dr. Mary Beth Hall discusses the carbohydrate chapter. She explained the equations didn’t drastically change but they discussed the different types of carbohydrates in more detail and had a better understanding of starch and fiber. (30:40)

Dr. Paul Kononoff discusses the gaps that are possibly in the new NASEM for the next committee to work on in the future. He stressed the importance of reporting chemical composition of feeds and forages. This will not only give a better understanding to those using the current equations, but it will also help the next committee when deciding on changes to those equations in the future. (45:55)

Ever wonder what animal scientists talk about after the formal presentations are over and the notebooks are put away? Real Science Exchange-Dairy captures that exact spirit, moving beyond the lecture hall to explore the ideas shaping dairy and animal nutrition. Presented by Balchem Animal Nutrition & Health, this series feels more like a lively, insightful table conversation among colleagues than a staged interview. You’ll hear leading researchers and experts discuss pressing topics in the field, but in a relaxed, unfiltered way that reveals the person behind the data. The dialogue is driven by genuine curiosity and a shared passion for natural sciences, covering everything from emerging research to practical applications. Each episode is an exchange of perspectives, offering a range of new ideas that challenge conventional thinking. It’s a podcast for anyone interested in the real-world science that impacts animal health and productivity, delivered with the authenticity of a discussion among friends. Tune in for thoughtful, accessible conversations that connect complex concepts to the bigger picture of life and scientific discovery.
