One of the impacts of aquaculture on the environment is the production of waste (guts, skin, scales, etc.), building silo from guts can be avalid environmental option and can be used to feed other animals. Objective. The project evaluated the effect of fish viscera silage in fattening sheep. Materials and methods. 20 sheep were evaluated in two random groups, with initial average weight of 17± 2kg for a period of 5 months. They were fed on fresh Maralfalfa (Pennisetum spp) and buttercup (Tithonia diversifolia), fresh, and one group additionally received silage at a rate of 3.5% of the total diet. The animals were weighed monthly to identify weight gain. Results. The silo showed for Microbiology UFC zero, the bromatologics analysis indicates PB of 39.88%; E.E.16.8% and 5% ash; the pH was 3,5 Sex, time and silage show significant differences (p <0.05) on the weight. The interactions were not significantly different (p>0.05). Conclusion. Preliminary results indicate that silage can be used for feeding sheep, further research is sugested to determine digestibility and other levels of inclusion.esAcceso abiertoCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráEnsilajeSubproductosAcuiculturaOvinosDesarrollo sostenibleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAcces
