Features and Benefits of POET Distillers Grains for Dairy Formulations

POET® Distillers Grains’ unique nutrient profile makes it a perfect ingredient for dairy cattle formulations. The following list includes a few key features that provide value to both dairy producers and nutritionists.

Reduced Fat

Feeding greater amounts of fat in the diet of lactating dairy cattle—specifically unsaturated fat like that in corn oil—can result in cows producing less fat in the milk, called milk fat depression.

Because of the BPX process that POET uses to produce bioethanol and distillers grains, POET can extract more oil than other bioethanol producers. The lower fat in DDGS provides a significant advantage over other non-POET DDGS for dairy cattle.

Improved Digestibility

POET’s BPX process minimizes the amount of heat during bioethanol and DDGS production. This reduces the negative effects of the Maillard reaction which can bind some of the protein and fiber.

Greater digestibility means the animal can capture and use more of the nutrients in POET Distillers Grains compared with non-POET DDGS. This results in greater energy and value for the animal.

Biohydrogenation Pathways of Trans-Fatty Acid

Biohydrogenation Pathways of Trans-Fatty Acid Intermediate Production Linked to Milk fat Depression (Adapted from LOCK, 2009) Linoleic acid (cis-9, cis-12 C18:2)

Biohydrogenation Theory for Milkfat Depression. Feeding too much linoleic acid—a fatty acid in DDGS—results in the production of certain fatty acid intermediates, which cause decreases in milkfat production. Feeding less linoleic acid minimizes this risk. (1)

NDF Digestibility

Improved Digestibility. Faster rates of NDF digestibility mean that dairy cattle can capture more of the energy in the fiber. Greater amounts of energy mean better performance—more milk production, energy for reproduction and weight gain.


Dairy cows require fiber in their diet to maintain optimal performance and good rumen health. Too little fiber can cause cows to develop conditions like acidosis or sub-acute ruminal acidosis (SARA).

Research has demonstrated that POET Distillers Grains can effectively replace alfalfa hay in lactating dairy cow diets. This provides flexibility in formulation and potential cost savings when forages become scarce or over-priced.

Forage Replacement – UNL Research

Fiber. Research at The University of Nebraska demonstrates that POET Distillers Grains can replace higher-priced alfalfa hay in lactating dairy cow diets. This study replaced 100% of the alfalfa (18% of the diet dry matter) and observed similar intake and equal or better milk production with no effects of milk fat.

Cost Competitive

Producers and nutritionists need to consider costs and look at metrics like income over feed costs to determine the best strategies for ingredient purchases.

POET Distiller Grains provide a great source of both protein and energy. We can use software programs like Sesame and AMTS to demonstrate the POET Distillers Grains provide significant value when factoring in the complete nutrient profile.
