Proyecto de una unidad de cultivo de forraje verde hidropónico para producción de cuyes (Cavia porcellus) en la granja de Irquis

Abstract

The project proposes a hydroponic green fodder (HGF) production unit inside a Wallipin at the Irquis of farm at the University of Cuenca, with the aim of ensuring a constant, nutritious, and sustainable supply of food for guinea pigs, as well as strengthening the academic development and research of students and teachers. A production assessment identified problems in conventional forage production, affected by climate variability and deficiencies in farm management (feeding, production, and reproduction of guinea pigs). One of the alternatives that can reduce the forage deficit is the production of FVH, produced mainly from barley and oats, which offers advantages in nutritional value, water efficiency, and speed of production, making it a sustainable option. Direct and documentary research was conducted on primary and secondary information on the Wallipin system, which is inspired by andean technologies and functions as an underground greenhouse that generates a stable microclimate, improves hydroponic productivity, and reduces the impact of extreme temperatures. The proposal integrates cultivation modules with germination trays, automated irrigation, a solar energy structure, and a technical management protocol. The economic and financial analysis, based on infrastructure costs, indicates an initial investment of USD 8.319,17 and operating costs of USD 4.344 with a projected production of 23 kg per day of HGF. The financial indicators show a Net Present Value of USD 10.023,47 and Internal Rate of Return of 36,47 %, and a Benefit-Cost Ratio of USD 1,04 confirming the feasibility of incorporating the HGF unit into the Irquis of the farm.
