Experimental Studies for Growth and Bioenergetics in Eudrilus eugeniae under Three Agro-climatic Conditions of Rainy, Winter and Summer
Journal Title: Universal Journal of Environmental Research and Technology - Year 2011, Vol 1, Issue 4
Abstract
Energy transformations and energetic of oligochaete species is available in population/ecological energetic of the soil inhabitants of the temperate and tropical regions. The study of bioenergetics is relevant for both basic sciences as well as applied fields to assess the environmental impact on the economically important organisms like compost earthworms. In the present research an experiment has been implemented to study the utilization of food budget in the tropical compost earthworm Eudrilus eugeniae under regular seasonal patterns of rainy, winter and summer by providing ad libitum partially-aerobically decomposed cattle dung. This study was done to know the effect of season on the feeding, defecation and cocoon production of the earthworms for its best utilization from the point of commercialization under three agro-climatic conditions. The fate of eaten food from hatchlings to post reproductive periods were documented for the study of growth period, growth, food consumption, daily food intake as a function of age group, total food intake as function of age group, feeding rate, feces defecation, food assimilation, assimilation rate (ASR), assimilation efficiency (ASE), conversion of assimilated food into body substance, conversion rate, gross conversion efficiency (K1), net conversion efficiency (K2), food oxidized as an expression of metabolism and metabolic rate. The impact of season on the feeding, defecation, absorption, assimilation and cocoon production has been discussed in detail.
