Ground Rice Hulls: Lightweight, High-Fiber Functionality
A versatile, plant-based ingredient sourced with CERCO’s commodity expertise and nationwide supplier network.
What Are Ground Rice Hulls?
Ground rice hulls are the finely milled outer husks of rice grains—commonly used as a fiber source, flow aid, or filler in a wide range of feed and agricultural products. While once considered a milling byproduct, they’ve become an efficient solution for manufacturers seeking low-moisture, inert material with excellent bulk density control and fiber contribution.
Where Ground Rice Hulls Are Used
-
Ground rice hulls are commonly used in ruminant diets as a low-cost, non-digestible fiber source. They help stimulate chewing activity and support rumen health without contributing excess energy. Ideal for balancing total mixed rations (TMR) in dairy and beef operations.
-
In monogastric diets, ground rice hulls can be used to add bulk and regulate gut transit time. They are especially useful in early-stage formulations and when formulating for feed flowability. The inert fiber helps maintain ration structure without impacting nutrient digestibility.
-
Ground rice hulls are used in pet food as a natural, plant-based fiber to support digestive health and stool consistency. They’re a clean-label option for brands aiming to increase total dietary fiber without fillers. Often included in dry kibble, biscuits, and treat blends.
-
As a soil amendment, ground rice hulls improve aeration, porosity, and drainage. They break down slowly, making them excellent for compost mixes, potting soil, and organic growing systems. Ideal for replacing peat or perlite in sustainable blends.
-
Due to their fine texture and neutral characteristics, ground rice hulls are often used as carriers in vitamin premixes, mineral blends, and additives. They prevent clumping, improve flow, and allow for uniform distribution of active ingredients. Suitable for both feed and fertilizer applications.
