Abstract:The growth and reproduction of Eisenia foetida in different mixtures of pig (feeding on corn or feedstuff) dungs and stalks (corn or paddy) indicated that weight of E. foetida increased significantly during the period of 0~30 d, slowly during the period of 30~60 d, and then decreased from 60 to 90 days, which possibly were related with reproduction of E.foetida or available feed decreasing in different mixtures. The trend of daily cocoons was increasing in the mixtures of pig dungs and stalks. The difference of pig dungs, stalks and the percentage had significant impacts on the weight dynamics of E. foetida. The growth and reproduction of E.foetida were the largest in the mixture of pig (feeding on corn) dungs and corn stalks especially at the percentage of 50%. The fold weight increasing daily and cocoons production daily of E. foetida in the mixture of pig (feeding on feedstuff) dungs and corn stalks were more than that of pig (feeding on feedstuff) dungs and paddy stalks. The results would provide scientific evidences for the optimal utilization of pig dungs and corn stalks in the suburban of Jilin province.
