VILLA-RAMIREZ, RIGOBERTO. Feeding Rainbow Trout (Oncorhynchus mykiss) by chemical silage of trout in the fattening phase. Rev.EIA.Esc.Ing.Antioq [online]. 2021, vol.18, n.35, pp.54-63.  Epub Oct 22, 2021. ISSN 1794-1237.  https://doi.org/10.24050/reia.v18i35.1468.

In the Truchas Cócora Piscine Unit in the municipality of Salento Quindío rainbow trout (Oncorhynchus mykiss) were fed with three different wet concentrates made from silage of rainbow trout viscera and three commercial concentrates (cores), in 320 fish. A chemical silage of rainbow trout visors was elaborated and used during the fattening phase, for the analysis of the data a completely randomized design was used, with four treatments and four repetitions each; the variables to be measured were weight gain, feed consumption and feed conversion, analyzed by the analysis of variance (Anova); being that in control treatment (T4), it presents the highest weight gain (129.7 gr) while TI was the lowest weight gain (120 g), although the analysis of variance showed that there are no significant statistical differences for none of the variables under study.
