Why steamed hay can lead to protein deficiency in horses

Steaming hay kills harmful microorganisms, but damages proteins making them less digestible for horses. This can lead to impaired muscle development and nutrient deficiencies, affecting growth and coat health. Horses can be enriched with protein-rich feedstuffs to mitigate this risk.
