Straw or chaff is a high-fibre low-sugar forage that is ideal for horses that are overweight or insulin-resistant. Straw adds bulk to your horse’s diet without contributing significant calories or protein.
Research shows that adding straw to a forage ration can increase time spent grazing and the expression of natural foraging behaviours. [1] This can improve wellness and prevent boredom without adding excess energy to the diet. 
While straw is not widely used as horse feed in North America, chaff or chopped straw is commonly fed in the United Kingdom. Mixing straw with other forages is recommended to avoid health concerns that are associated with feeding a straw-only ration.
Here, we discuss the benefits, risks and considerations of adding straw to your horse's diet.
