Currently offered for corn and complete feeds.

Improved Nutrient Digestibility:

Proper particle size increases the surface area of the grain, making it easier for animals—especially monogastrics like pigs and poultry—to digest and absorb nutrients.

Feed Efficiency:

Achieving the right grind size (often referred to as the “sweet spot”) ensures animals get the most energy and nutrients from the feed, leading to better weight gain or production with less feed input.

Pellet Quality:

For pelleted feeds, uniform and appropriately sized particles contribute to better pellet durability and less fines, improving overall feed quality and reducing waste.

Reduced Feed Wastage:

Inconsistently ground feed can lead to sorting by animals and increased feed losses, particularly in dry feeding systems.

Animal Health:

Very fine particles can lead to gastric ulcers in pigs or respiratory issues due to dust, while too coarse particles may reduce digestibility or cause selective feeding.

Grinding Efficiency:

Overgrinding increases energy use and wear on equipment. Particle size testing helps balance grinding precision with cost-effective mill operation.

Consistency and Quality Control:

Routine particle size testing ensures batches are consistent, supporting predictable animal performance and maintaining feed mill quality standards.

We use an industry-standard 13-sieve method as outlined in ASAE S319.5 and include a sieving agent.

Benefits of Using a Sieve Agent

• Reduces static electricity and friction during testing.
• Promotes even distribution of particles across sieves.
• Results in more accurate and repeatable particle size measurements.

We use NIR (Near-Infrared) analysis for rapid, non-destructive testing.

Every sample includes:

• Proximate nutrient predictions
• Amino acid profile predictions

Clients have access to an online database to:

• Track historical results
• Chart trends over time
• Detect process shifts or ingredient variation early

Pellet quality testing is traditionally done with a tumbler machine to measure pellet durability.

We use the Holmen NHP 300, a faster and more consistent method for evaluating pellet quality. The process includes:

1. Measuring initial fines in the sample
2. Using air pressure agitation via the Holmen system for a set time
3. Measuring the remaining whole pellets after agitation

• Percent Initial Fines
• Percent Durability
• Estimated Percent of Pellets Delivered to the Animal

• Quick and cost-effective
• Provides actionable data to optimize pellet quality and improve milling efficiency

• Important for marketing strategy—tolerance levels vary widely by end user (e.g., feed mills, ethanol plants, elevators).
• Pre-testing saves time and helps plan deliveries more effectively.
