Animals don’t lie – their performance is based on the quality of feed they consume. Knowing the quality of ingredients in the diet formulation, can be as important as the formulation when determining the health and performance of your animals. A poor diet results in slow gain, increased feeding costs due to a higher feed to gain ratio, and increased total production costs.

Research at universities such as University of Illinois and Kansas State University have proven that full-fat soya and defatted soya meal produced on Insta-Pro equipment, increases animal performance and reduces total production costs. With one change to high-shear dry extruded soy meal, customers have saved 4% on their overall diet costs AND produced almost 1kg more milk/head/day. Egg producers have reached the large caseweight size category six weeks earlier, thanks to 3,4% higher lysine availability.

Technically superior ingredients

Soya meal

Fifty years ago, our extruders began processing full-fat soya, which is a stabilising force in diets. Helping to obtain predictable animal performance, customers can expect 85 to 90% amino acid digestibility and high energy resulting in 2 to 4% reduced diet costs. 

With the addition of mechanical oil pressing to form the ExPress® technology, processors further add value to soya beans, rapeseed, sunflower and other oilseeds. In addition, partially de-oiled soya meals, following high-shear dry extrusion, fit dairy formulations quite nicely, providing highly digestible rumen bypass protein, as well as rumen bypass fat. Coupling superior nutritional benefits with precision-built, long-life equipment, our customers in Africa routinely see a payback in less than two years.

Extruded maize/corn

You can expect 18% improvement in rumen starch digestibility with extruded corn when compared to steam flaked corn. High-shear dry extrusion of maize grain and rice bran are among our latest technologies. Now, cereal grains and co-products can be improved with extrusion and stabilised for long-term storage – effectively enhancing the usefulness of the nutrients.

High-oil seeds: Rapeseed

Oilseeds with greater than 30% oil content, such as rapeseed/canola, sunflower, and linseed, offer alternatives to soya, which is not widely available at economical prices for animal producers. High-shear dry extrusion, in conjunction with double pressing, can be used to produce higher-quality ingredients.

For example, double pressed high-shear dry extruded canola meal exhibits 12% units greater lysine digestibility in broilers versus expanded/pressed canola meal, as well as 439 more kcal/kg of metabolisable energy (roughly 14% of the total kcal in a broiler diet). This resulted in a 5% reduction in total diet costs for a typical corn/canola meal broiler diet.  

A profit centre, instead of a cost centre

Feed millers traditionally buy in their soya bean meal and soya bean oil from a large-scale solvent plant. With soya bean meal making up 20 to 30% of a typical monogastric ration, this is a major cost centre. 

Becoming a small- or medium-scale soya bean processor, producing 20-500mt/day soya bean meal, can be challenging at first, but a feasibility analysis will show the way forward. Typical payback periods can be short, thanks to the high value of the soya bean oil.


The feed miller processor is in full control of meal quality. The quality of the final product is determined by quality of the raw material and the equipment used to process it. When choosing a technically superior extruder and oil press from Insta-Pro, you purchase technically superior equipment with a long life that are proven to be beneficial to animals and the bottom line. What was a cost centre, becomes a PROFIT centre. – Dr Dave Albin, PhD, Insta-Pro
