General protease activity increased in PL in treatments 1 and 4, with low values from 1
PL to PL . In treatment 3, general protease activity decreased from M to PL , 2 10 III 2
remaining low thereafter. In the animals fed on artificial diet alone (treatment 2), general
protease activity is high until PL and decreased in the rest of the stages. MCD caused 2
higher proteolytic activity during all the stages when compared with the other treatments
(Fig. 2a).
