Abstract
The present study was undertaken to evaluate the infrastructural requirements, cost structure and profitability of large-scale silkworm rearing under controlled irrigated conditions. The research focused on the rearing of double hybrid disease-free layings (dfl’s), supported by the establishment of suitable infrastructure and essential equipment for successful lateage rearing. A rearing house inclusive of Chawki and shoot storage facilities was constructed at a cost of ?3,00,000 and rearing equipment worth ?58,400 was procured thus leading to a total fixed capital investment of ?3,58,400. The economic analysis revealed that the total variable cost incurred was ?2,91,400, with significant expenses attributed to labour (?1,62,000), DFL procurement (?64,800), and leaf feeding (?54,000). When fixed costs (?35,840) were added, the total cost of production amounted to ?3,27,240. Cocoon yield was estimated at 80 kg per 100 DFLs resulting in a total yield of 1,440 kg. At an average market rate of ?350/kg, cocoon sales generated ?5,04,000 supplemented by ?80,000 from by-products. The total revenue reached ?5,84,000 thereby yielding a net profit of ?2,56,760. The benefit-cost ratio was calculated at 1.78 thereby indicating strong economic viability. The study concludes that with proper infrastructure, efficient resource use and scientific management, lateage silkworm rearing in irrigated conditions is a profitable and sustainable enterprise and well-suited for the agro-climatic conditions of Udumalpet and similar regions in Tamil Nadu.
