Enrich your aquafeeds with distillers grains. These partial fish meal replacements can function as an alternative protein source for your aquaculture.

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.

Use of Lipid-Extracted DDGS in Diets for Pacific White Shrimp

A series of trials (one growth trial and two digestibility trials) were conducted to evaluate the response of Pacific white shrimp Litopenaeus vannamei to the inclusion of lipid-extracted distillers dried grain with solubles (LE-DDGS). Based on the observed results the inclusion of LE-DDGS up to 20% of the diet is recommended.

Replacement of Fish Meal in Practical Diets for the Pacific White Shrimp (L. vannamei)

The use of a co-extruded soybean poultry by-product meal (CEPM) and flashed dried poultry by-product meal (FD-PBM) was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Under the reported conditions, survival, FE, and PCE values were either improved or were not significantly influenced by the replacement of menhaden fish meal with either CEPM or FD-PBM.
