The profile of Dakota Gold fits naturally with that of a lactating dairy cow. Low fat, high digestibility fiber and protein are the perfect blend for optimized milk production. Learn more about Dakota Gold characteristics.

DDGS and Milk Fat Depression - Perception or Reality?

This webinar features Dr. Hugo Ramirez from Iowa State University. who provides key insights on management and formulation strategies to effectively feed DDGS without affecting milk fat production. Mr. Dave Peschong from POET also presents a market update on factors affecting DDGS pricing and availability.

Wrinkle: Can Dakota Gold Replace Alfalfa Hay?

Most dairy producers know that when they feed Dakota Gold or other non-POET DDGS, they can replace ingredients like soybean meal and corn. However, very few producers realize that they can also replace a portion of the fiber coming from other sources. Fiber (as measured by NDF) comprises approximately 1/3 of the nutrients in DDGS. Furthermore, this fiber represents an extremely digestible source which provides additional energy to the dairy cow.

Wrinkle: Research Challenges the Perception of DDGS & Milk Fat Depression

Feeding ingredients that contain greater amounts of unsaturated fat tend to increase the chance of milk-fat depression in lactating dairy cows. Unfortunately, many producers saw this effect when they first started feeding DDGS prior to the ethanol industry's movement towards oil extraction. As a result, many producers and nutritionists still perceive that DDGS causes cows to produce less milk fat. However, a summary of peer-reviewed data challenges this perception.

Wrinkle: DDGS vs SoyPass - Do DDGS Provide Ample Protein?

What additional protein do I need to include when I’m feeding distillers?” We often get this question from producers or nutritionists because they feel additional types (ruminally available vs “bypass”) of protein will promote animal performance. To address this question, University of Nebraska researchers conducted two experiments to measure cattle response to either urea or SoyPass. Results from both studies provided additional insights on this very important question

Wrinkle: How Do DDGS Impact Heifer Weights?

A significant amount of research exists on feeding distillers to dairy cows, swine, poultry, and beef. However, very little research exists on feeding DDGS to replacement dairy heifers. This lack of data for replacement heifers represents a missed opportunity for producers as DDGS provides an excellent source of nutrients that match very closely with the nutrient requirements of heifers.

Wrinkle: Open Sesame to Unlock Dakota Gold Treasure

Determining the nutritional value of DDGS can sometimes prove difficult. We can measure value based on dollars per unit of protein or energy or perhaps calculate as a percentage of corn. However, DDGS provides both protein and energy and as a result, when we calculate value based on a single nutrient such as protein, we underestimate DDGS value. Comparing nutritional value to other ingredients using software such as Sesame provides a compromise between these two different approaches.
