The experiment was carried out at "campus da Universidade Federal de Lavras", in order to compare the performance of African and Red earthworm produced in earthworm box with buffaloes and cattle manure. The experimental period was of 40 days and the experimental design was completely randomized in a factorial arrangement 2 x 2, totalizing four treatments with four replicates each. The red earthworm gained (P<0,01) weight, while the African earthworm lost weight. The types of manure did not influence on earthworm performance (P>0,05) for weigh gain. The earthworm box was efficient for production of red earthworm, but the African earthworm did not adapt at this production system. For mineral percentage in fresh feces, there is superiority (P<0,01) of cattle in relation to buffaloes concerned to ash, nitrogen, phosphorus, calcium, magnesium, iron, zinc, while there was no difference for sulphur, copper and manganese (P>0,05), and the buffaloes were superior only for potassium (P<0,01). For mineral percent present in earthworm humus there were interactions between manure source and earthworm species for nitrogen, potassium, zinc and copper. The higher nitrogen and copper percent was observed for earthworm manure from cattle with red earthworm (P<0,01) and for zinc, the better combinations were African earthworm with cattle and Red earthworm with buffaloes (P<0,01). Considering analyzed and isolated factors there was difference for phosphorus (P<0,05) favorable to humus earthworm from cattle manure, for calcium and magnesium (P<0,05) favorable to cattle manure and African earthworm and for iron (P<0,01) favorable buffaloes manure and African earthworm. There was no difference (P>0,05) for any variation source relating to ash, sulphur and manganese. It was concluded that earthworm box is efficient for Red earthworm production (P<0,01), since African earthworms don't adapt themselves that raising system. Cattle feces are better sources of minerals than buffaloes feces and for humus earthworm interactions happen when buffaloes and cattle manure are utilized with African and Red earthworm.
