The aim of this study was to evaluate the effect of three regrowth ages and three levels of inclusion of pisonay (Erythrina edulis) meal on feed consumption and conversion; body weight gain, and carcass rate in guinea pig fattening (Cavia porcellus). Shade-dried leaves and petioles of harvested trees were used and mechanically processed to 2 mm particle size. In total, 120 improved male guinea pigs were used, distributed in 10 treatments (3 regrowth ages, three levels of meal inclusion and a control group with alfalfa meal) for 56 days. The total and daily weight gain, in addition to the feed conversion had a similar response between treatments; feed consumption was lower with the 8M30% treatment (54.0 g/day) with respect to CA20% (59.3 g/day) (p<0.05) and the carcass yield was higher in 4M20% (73.5%) compared to the control diet (71.1%) (p<0.05). Feed consumption (60.3 g/day) as feed conversion (5.3) was higher at 12 months of regrowth age (p<0.05) with respect to 4 and 8 months, which were similar to each other. Carcass yield was similar (72%) with the inclusion of 10 and 20% and decreased (70.6%) with 30% pisonay meal (p<0.05). The pisonay meal used as a feed input for the production of concentrate does not affect the productive characteristics of guinea pigs.
