Certain food items pose significant health risks to equines and should be strictly avoided in their diet. These substances contain compounds that horses cannot properly digest or that are directly toxic, leading to a range of adverse reactions from mild discomfort to life-threatening conditions. An example includes plants containing pyrrolizidine alkaloids, such as ragwort, which cause irreversible liver damage.
Preventing horses from ingesting unsuitable foods is paramount to their well-being and longevity. A carefully managed diet reduces the incidence of colic, laminitis, and other serious ailments. Historically, understanding equine nutritional needs and potential dietary hazards has been essential for ensuring the health and productivity of working animals and companion horses alike.
