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

Royce;
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.

Can extruded full fat soya or extruded expelled soyabean meal, be a source of bypass fat and bypass protein?

sasil Unfortunately, you need a high-shear dry extruder with high pressure, shearing forces, and ultimately greater extrusion temperatures (but all for a short time) than what you indicate. We can help you with this. Please email me. dalbin@insta-pro.com

I intended to add that it may be more efficient to evaluate what your machine can do efficiently to process the soybeans than to ask it to do something for which it is not intended. Quite often, working to produce the best product available from our equipment is still preferential to not working to improve the feeding value of the original grain or product we need to work with. That is where you have to use an experienced and competent consultant to assist in getting the optimum from your existing machine. I assume you are planning to use the extruded product to supply nutritional value for dairy cattle. You may need to look at what the cattle really need. My experience in working with Indian dairy production is that the first level of nutrition needed is to supply adequate basic nutrition for the animals. Only if the animals are capable of or being managed for high milk production is it necessary or economically feasible to formulate with special nutrients like by-pass protein or rumen protected amino acid products. High by-pass protein without basic supplies of available energy, rumen soluble protein, minerals and vitamins may actually decrease milk production.

Dry extruded whole soybeans known as Full fat soya has good amino acids profile. it can be used at 25-35% inclusion rate in commercial broilers. Birds utilize the full fat soya and express it in the overall performance because of the digestibility. Cost of feed will be reduced due to the high energy content of full fat soya and presence of the oil will reduce the dustiness of the feed in mash form.Combination of the high energy and digestible protein content of the extruded Full-fat soy makes it efficient.

Amin Nthanga this is very important to be considered in broiler nutrients, especially at starter phase of feeding.

Yes sir, I would like to join the discussion.
