Using Dry Extruded Whole Soybeans (“Extruded Full-Fat”) in Formulations

Author/s : Dave Albin, PhD / Director, Nutrition & Extrusion Technologies at Insta-Pro.

For several decades, Insta-Pro International has been well known around the world for dry extrusion, which we invented in the 1960’s.Dry extrusion was invented to process soybeans, and over the years, this process has been well researched. The advantages of this technique are the following: Thorough plant cell wall rupture, providing much improved access to nutrients Deactivation&nb...

I am also using dry extruded cottonseed as well as extruded soybeans. Do you have similar information for the nutrient characteristics of the Ext CSM. Do you see any drop in the anti-nutritional characteristics of the extruded cottonseed?

Extruded cottonseed meal is also a great ingredient for animal feed, however, it is very important to know how the cottonseed is processed to get the oil out from the seed.

Whole white cottonseed (with lint and hulls) is a very hard application on the oilseed industry, the best way to process this seed is to remove the lint by using delinters and dehull the seed by using dehullers, then you process only the meats from the cottonseed, by doing this the oil content in the seed increases from 18% to 30-31%.

Temperature on the dry extruder is very important to deactivate gossypol which has limitations or restrictions on the inclusion on animal feeds due to toxicity.

Basically, the use of various ingredients to supply the most cost-efficient supply of nutrients to meet the requirements of the animal being fed is the goal of ration formulation. There are few magic ingredients. Also, there is no single processing system that always provides the best ingredient. As some of the discussions indicate, full fat soy often meets energy requirements before balancing AA needs. However, when you look at using synthetic AA to complete the ration formulation, we can often use a wide array of ingredients in successful, economic ration formulations. With the supply and cost of ingredients changing constantly, ration formulation becomes an ever-changing process that requires the nutritionist, feed supplier and animal producer to constantly evaluate ration formulation. Nutrition remains an art as much as a science!

Royce Samford It does indeed, which is why it's important to have a controlled process that can provide high-quality ingredients time after time.

Soybeans are an excellent candidate. I am currently trying insects
