High in starch value, but low protein value, include barley grain at 40% or less dry matter. Avoid waxy barley for use with pigs or poultry. Lambs are the only animal that doesn’t require additional processing of barley before feeding. Dry rolling increases rumen digestibility by 16% and starch digestibility by 37%. Additional processing methods that increase starch and rumen digestibility include roasting, aldehyde treatment, and ammonia. Awned barley may cause irritation and result in stomatitis in horses, cattle, and poultry. Barley grain is susceptible to scab under hot and humid conditions and in turn, result in the production of mycotoxins. Weight loss, lower feed conversion, vomiting, bloody diarrhea, severe dermatitis, and death are all signs of toxicosis. Harvested grain containing greater than 5% infected kernels can contain enough toxin to be harmful to humans and animals. Barley also contains Pentosans and should not be utilized for poultry.
