The Key Factors in Sourcing Reliable Feed-Grade Limestone

3-Minute Read that Could Change Your Feed-Grade Limestone Sourcing 

Farmers, feed mills and grain companies know the importance of sourcing dependable feed-grade limestone. But doing so at scale can create challenges without the right partnerships in place. 

This month, we’re sharing our recommendations on what to look for in a reliable relationship when sourcing limestone. 

The Importance of Limestone in Feed

Limestone is a key calcium source in livestock feed, especially for poultry, cattle and pigs. Like in humans, better calcium sources support bone health, but it also helps with eggshell formation and dairy production. Of course, you can’t just put any type of limestone into an animals’ feed. It’s important to have a supplier with consistent quality and reliable logistics as part of your operations strategy.

Feed-Grade Quality Standards

For limestone that is feed-grade quality, a supplier needs to follow a specific process that meets particle size specifications of the product and is in compliance with feed safety standards. A reputable supplier will also ensure - and report - that there are limited impurities such as magnesium carbonate and silicon dioxide. 

Logistics Coordination

Maintaining your production schedule relies on consistent and smooth delivery of the product. For many, the logistics and freight coordination are just as important as the quality of the product itself. Once connected with a supplier, consider how that product will get to you, and what happens if weather or resources impact feed delivery.

Is there a one-stop shop for sourcing and delivering my feed ingredients? 

Having a clear, big-picture awareness of your feed ingredient strategy - its quality and consistency - is possible with the right feed ingredient partner. A limestone distributor and logistics provider can help connect the dots between a reputable feed ingredient supplier and ensuring that product is delivered on time. 

Strong Supplier Network 

Long-term experience in the industry includes a partner who not only understands feed formulations and livestock nutrition needs, but who also has an established network of suppliers that they trust. 

Having a partner who has already sourced, vetted and recommended suppliers is an important part of the puzzle, not just for initially finding feed ingredients, but also if a pivot is necessary in the future. Should a supplier run into disruptions, a backup network of suppliers will ensure that quality feed is still on its way to you.

Reliable Logistics Network 

Decades ago, mom and pop farms would simply pull their pickup truck right to the supplier’s front door to pick up their order. Now, productions are much bigger, and a little more complex, especially when things happen out of our control (like bad weather or price changes). A reliable partner who has both a strong supplier network and a reliable logistics network to ensure your product is delivered on schedule can take the stress of waiting for a shipment off of your plate.
