Nutritionally Improved Straw - Feed Ingredient

Nutritionally Improved Straw refers to straw that has undergone processing to enhance its digestibility and nutritional profile. Straw a byproduct of grain harvesting, is naturally low in protein and energy and contains a high proportion of indigestible fiber.

The most common method of improvement is alkali treatment—such as ammoniation or sodium hydroxide application—which alters the fiber structure and reduces lignin content. Lignin is a structural plant polymer that is indigestible and can interfere with nutrient availability.

In equine nutrition, nutritionally improved straw serves as a low-calorie forage-based fiber source. It is often incorporated into complete feeds, forage pellets, or cubes to provide bulk, stimulate chewing, and promote gut motility. The treatment process enhances the digestibility of cellulose and hemicellulose, making the straw more suitable for horses with limited energy requirements. Despite its improved digestibility, it remains low in protein and essential nutrients, and is typically used in combination with other forages or concentrates to achieve a balanced diet.
