Pellet Durability: A Metric to Handle with Care
Published: July 29, 2025
Summary
Among the many quality criteria in animal feed production, pellet durability is often cited as one of the most critical. And rightly so: fragile pellets tend to generate too much dust and fines, which can impact feed intake, zootechnical performance, and even trigger complaints from farmers. It’s no surprise, then, to see a growing number of posts, articles, and expert opinions stressing t...

Excellent article addressing such an important topic for our industry.
It provides a balanced perspective on a metric that is often interpreted out of context. I agree that Pellet Durability Index (PDI) is a highly valuable tool for process monitoring, but it should not be regarded as an absolute guarantee of pellet physical quality at the point of consumption.
The article also appropriately highlights the impact of handling, transportation, storage, and feed distribution systems on the final physical integrity of pellets.
In my opinion, one of the article's main contributions is its reminder that pellet quality should be evaluated throughout the entire supply chain, not only at the pellet mill discharge.
Therefore, PDI should be complemented with additional indicators and field evaluations at the point of use.
Without a doubt, this is a valuable technical reflection that encourages further discussion on the concept of overall pellet physical quality.
