Can you improve your broiler performance, bring broilers to market earlier and make more money?

During Wednesday afternoon’s TECHTalk at the International Poultry & Processing Expo (IPPE), Dr. Dave Albin with Insta-Pro International discussed four mechanisms to do just that.

  1. When it comes to broiler nutrition with dry extruded corn, high-shear dry extrusion reduces molecules size of nutrients and thoroughly gelatinizes the starch, which reduces viscosity, therefore increasing feed intake
  2. The high-shear dry extrusion of corn increases ME by 18% over ME of ground corn. That means 95% of total energy in dry extruded corn is metabolizable versus 83% in dry corn, which means more energy in corn is available for growth following high-shear dry extrusion
  3. With ExPress® soybean meal, high-shear dry extrusion and mechanical oil pressing improve amino acids digestibility versus solvent-extracted soybean meal and mechanical soy meal. Therefore, more amino acids are available for growth with the same level of feed intake
  4. ExPress® soybean meal formulations bring along more ME and total dietary fats/oils versus solvent-extracted soybean meal and mechanical soy meal. More ME and dietary fats/oils from high-shear dry extruded soy improve body weight and gain and feed efficiency, which means enhanced gut architecture, reduced passage rate, improved digestibility of other nutrients, and more energy retained in the bird available for productive purposes.

According to Dr. Albin, a recent study by Dr. Bobeck at Iowa State University evaluated the efficacy of extruded ingredients demonstrated highly impactful feeding benefits for broilers.

The goal of the feeding trial was to determine how the use of high-shear dry extruded corn, high-shear dry extruded/partially-de-oiled (ExPress®) soy meal, used alone with the commodity version of the other ingredient, or fed together in combination, affected growth performance of Ross broilers.

The diets were balanced for the nutrient requirements of the birds and fed in three phases (starter, grower, finisher). Some important benefits discussed are:

  • 12.4% augmented feed intake; 12.9% increase in body weight gain; and an improvement of 0.5% in feed conversion ratio. (ExPress® + extruded corn versus. SBM + ground corn)
  • 18% increase in metabolizable energy when using extruded corn vs ground corn
  • Market weight achieved 4.8 days ahead of competitors while consuming about 12 grams fewer of total feed. (ExPress® + extruded corn vs. SBM + ground corn)
  • With dry extruded corn vs. ground corn, birds required 2.4 days less to market

This landmark feeding trial This study proved that by combining ExPress® soy meal & extruded corn, broilers would see a 6.12% improvement in feed conversion, as well as reach target weight 4.8 days sooner than they would if they were fed another feed combination.

The ISU Broiler Trial remains one of the most impactful feeding trials in recent memory; providing us with the data necessary to evaluate financial benefits broiler producers could obtain by adjusting their feed ingredients.

However, combining ExPress® soy meal & extruded corn was not the only major benefit pulled from the study. By switching to only high shear dry extruded corn, your broilers will reach target weight 2.4 days earlier to market, when compared to a diet composition of consisting of ground corn.

This minor adjustment alone could save you thousands of dollars in the long-term. Ultimately, the investment and returns are heavily dependent on your own operation.

Further analysis evaluated that feeding a five million bird flock could pay back an investment of a soy and corn extrusion plant is less than two years.

Insta-Pro acknowledges each broiler producer will have differences in flock size and costs. To address this, the company has been conducting free financial feasibility analyses in order to account for operation-specific variables.
