With the implementation of the Food Safety and Modernization Act (FSMA) in 2018, tracing mycotoxins throughout the food chain came into focus. Dairyland is committed to providing fast, accurate, and repeatable results, motivating us to invest in bringing our mycotoxin testing in-house. We are proud to offer the industry gold standard with HPLC-MS/MS using radiostable isotopes. To learn more about our methodology, why this matters, and our full offerings, check out our mycotoxins page.



At Dairyland, we are committed to ensuring the highest standards of quality and consistency in animal feed production. To assist our valued customers in this endeavor, we offer Mixer Tests, a comprehensive service designed to assess the variability in mixer performance and ensure thorough mixing of the grain or mineral mix.

Our Mixer Tests involve the sampling of 5-10 samples during the load-out process, selected to track the variability of a specific mineral or nutrient throughout the mixing process. We provide detailed reports that include statistical metrics such as standard deviation, offering valuable insights into the uniformity and thoroughness of mixing achieved by your equipment.

By leveraging our Mixer Tests, customers gain critical information that empowers them to optimize their mixer settings, enhance production efficiency, and ultimately deliver superior quality feed to their livestock.

Coefficient of variation (CV) Interpretation
0-5% Superior - meets or exceeds all industry standards
5-10% Excellent - meets or exceeds most feed manufacturing standards
10-15% Good - acceptable for high forage ruminant diets
15-25% Fair - may be acceptable but room for improvement
25%+ Poor - may negatively impact animal performance

The durability of feed pellets is crucial to their physical integrity as they move through feed handling systems, while also impacting their palatability to livestock.  While traditional “tumble can” metrics for pellet quality have been available since the 1960’s, some implementations struggle to truly differentiate durability across a range of pellet types.  After an in-house assessment of several testing options, we’ve landed on the Holmen NHP100 as our pellet durability analysis of choice and are now offering a Pellet Durability testing package.


The Holmen NHP100 is designed to simulate the types of abuse pellets undergo as they move through feed transportation systems, using high-pressure air to bounce pellets off hard surfaces, some smooth and some grated, at multiple angles.  Then at fixed time intervals of 30, 60, 90, and 120 seconds, we quantify the amount of fines which are automatically filtered through a 2.5 mm screen.  For a clearer picture of how the analysis works, check out this video.


In our testing, we’ve found individual ingredient pellets to range in durability from 80-98% at 120 seconds, with mixed feed pellets having as little as 30% of pellets intact after 30 seconds.  Using the slope of measurements at multiple time points, pellet durability reports also include an estimated time to 50%, indicating how long it takes 50% of pellets to degrade into fines.


Grain particle size is one of the primary factors that dictate starch digestibility in both ruminant and mono-gastric animals. Grain that is not processed well enough results in slow or incomplete digestion and low feed efficiency. Grain particle size can be measured accurately and precisely by utilizing the method described in ASAE S319.4, which includes Ro-Tap shaking through a set of 14 sieves with various-sized apertures.

A Grain Particle Size report will include the weight and percentage of the same retained on each sieve as well as calculations of the Mean Particle Size (MPS) and 1 Standard Deviation Distribution.  Typical MPS values found for various processing methods are as follows:

Feed Grain MPS
Fine Ground - Dry Corn <750
Medium Grind - Dry Corn 750 - 1000
Coarse Ground - Dry Corn >1000
Whole - Dry Corn >4000
Fine Ground - High Moisture Corn <1000
Coarse Grind - High Moisture Corn 1000 - 2500
Rolled - High Moisture Corn 1000 - 2500
Coarse Rolled - High Moisture Corn >2500
Whole - High Moisture Corn >4000
Snaplage 750 - 2000
Prolamin content and extent of fermentation can also have a significant effect on the digestion of starch in ruminants. UW Grain 2.0 incorporates grain particle size, prolamin, and the extent of fermentation to give an accurate estimate of digestibility. 


High-oleic soybeans (aka Plenish beans), provide unique feeding value to dairy cattle and can be easily identified by their fatty acid profile. 

Soybeans, roasted soybeans, and soybean meal can all be submitted for fatty acid analysis. 

Dairyland is in the final stages of NIR calibration development for both in-field and lab equipment. 


Feed additives like monensin, lasalocid, and medications often offer on-site test kits that utilize tracers to identify the presence and concentration of these ingredients. 

When lab-based chemistry is warranted, or third-party verification is needed, contact us for specific sampling instructions unique to these additives.
