| Descripción: | The objective of the present study was to validate the inclusion of bovine viscera in the diet of Guppy fish (Poecilia reticulata) as an economically viable and attractive alternative, through the evaluation of growth and reproductive performance including dehydrated bovine heart and kidney in the formulation of feed rations. The 60-day investigation was conducted at the Aquaculture Module of the Alfredo Volio Mata Experimental Station (EEAVM), using 320 animals 30 ± 2 days of age. After a fifteen-day acclimatization period, 20 individuals were randomly assigned per tank. Four experimental treatments were used: Control, which included only commercial balanced feed (BF) for Guppy fish; Treatment 1 (T1), which was composed of only commercial BF for the Tilapia-starting phase; Treatment 2 (T2), which was formulated with 52.5% commercial BF for Tilapia-phase starting phase and 47.5% dehydrated bovine heart; and Treatment 3 (T3), that was integrated with 45.3% commercial BF for Tilapia-initiation phase and 54.7% dehydrated bovine kidney. General anesthesia was used in the animals every 15 days to take measurements of total weight gain (GPT), specific growth rate (SGR), thermal growth coefficient (CTC), feed conversion (FCR), and condition factor of Fulton (K). Significant differences (p < 0.05) were found in general average weight gain (GPg) and average weight gain for females (GPh) between T1 and the rest of the treatments, with no differences between the latter. No significant differences were observed for the fecundity variable between treatments (p > 0.05), however, there was a trend (p = 0.091) of a greater number of births in treatments T2 and T3. The economic analysis showed that the Control treatment has the highest cost, followed by T3, T2, and T1, respectively. This is the reason why the use of bovine viscera, in combination with commercial foods, is considered a technically and economically viable alternative. |
