Alimentación de truchas con proteína de Phaseolus vulgaris (fréjol) en la etapa de engorde, en el cantón Chambo provincia de Chimborazo.

Abstract

In the province of Chimborazo, Chambo Town, the productive behavior of trout in the fattening stage, fed with Phaseolus vulgaris protein (Beans), was evaluated in order to reduce the time of trout production. It was carried out under a Completely Random Design with three treatments (10, 20 and 30% bean flour) plus the control, divided into 4 repetitions with 20 trout, with a total of 320 fish in the experiment. The variation of the weights and sizes were taken every fifteen days, finally the feed conversion, mortality and Benefit / Cost were calculated, which were subjected to an analysis of variance (ADEVA) and separation of means according to the tunkey methodology at a significance level (P≤0.05). The bromatological analysis of Phaseolus vulagris was carried out. The research started with an average initial weight and height of 34.04 grams and 14.70 centimeters respectively. The results suggest that there were no significant differences between the treatments, but there were numerical differences. Finally reporting that the highest weights were in T1 with 118.13 grams and the best size for T3 with 22.10 centimeters. The best weight gain in T1 with 83.63 grams. In addition, a better performance to the carcass in T2 with 87.04% was observed. The lowest mortality was recorded in T3 with 1.25% and the calculated B / C ratio presented the best treatment in T1 = $ 1.12 obtaining a profit of 0.12 cents. It is concluded that 10% bean flour as a protein source implies better productive yields in terms of trout weight, weight gain, feed conversion and additionally lowers production costs. It is advisable to encourage local fish farmers to implement this feeding system for fish as a breeding alternative that shortens harvest time.
