Abstract
The effect of stocking rate and moisture content on the growth and maturation of Eisenia andrei (Bouché, 1972) in pig manure was studied in laboratory trials at 20°C. Six moisture contents (65, 70, 75, 80, 85 or 90%) and five stocking rates (1, 2, 4, 8 or 16 worms, each per the same volume of substrate) were tested. Growth and maturation of earthworms were monitored over 44 days. The 85% moisture content was found to be most favourable for earthworm growth. The 80 and 90% moisture contents were found to be adequate. Eight earthworms per 43.61 g (dry wt) was found to be the most favourable inoculation density.
