Summary

The trypsin-inhibiting activity (TIA) of 33 European spring pea varieties ranged from 1.69 to 7.56 TIU/mg DM with an average of 2.46 TIU/mg DM and a coefficient of variation of 56 %. The TIA of winter peas were 3 or 4 times higher than those of the spring ones (7.34 to 11.24 TIU/mg DM). The peas imported from outside E.E.C. and 4 of the 6 other legume seeds studied had an intermediate TIA. The growth conditions influenced the TIA of peas. The increase of the TIA in a pig diet from 1.2 to 3.8 TIU/mg DM induced a 5 % decrease (P< 0.05) of the apparent digestibility of the diet crude proteins.
