How trypsin inhibitors affect young animals

Trypsin inhibitors in soybean products are traditionally discussed as a piglet problem, largely because early soybean processing research focused on swine nutrition. Nursery pigs clearly respond to under-processed soybean meal, and this historical association has shaped industry perception for decades. However, when sensitivity is examined from a physiological and growth perspective, a different ranking emerges. Piglets are highly sensitive, but broiler chicks and pre-weaned calves may be even more vulnerable.
