Re-evaltoating soybean products in broiler feed

摘要

A recent study evaluated the effec ts of varying levels of trypsin inhibitor activity in bioiler feed ragging from 1.4 to 6.4 TIA units/mg, using soybean meal and extruded soybeans of different TIA concentrations. The National Institute of Agricultural Research in Argentina found that feed containing 2.4 TIA units/mg, did not affect broiler performance. However, levels above 3.4 units/mg were found to negatively impact broiler growth performance in a significant way.
