Productive performance of guinea pigs (Cavia porcellus) crossed with polydactyly in the rearing stage in Yurimaguas (Loreto, Peru) The objective of the study was to determine the effect of polydactyly on the productive performance of crossbred guinea pigs (Cavia porcellus) in the rearing stage. A total of 27 weaned male guinea pigs, of 20-days old and with an average weight of 450 g, were randomly distributed in three experimental units per treatment and repetition: T1 = (control): four anterior and three posterior toes, T2 = (guinea pigs with polydactyly): six anterior toes and six posterior toes and T3 = (guinea pigs with polydactyly): four anterior toes and four posterior toes and fed with forage (Pennisetum typhoides x P. purpureum), commercial feed (fattening stage) and water. Weight gain, feed conversion, and carcass yield were evaluated. Data were analyzed through ANOVA, applying Duncan's test for post hoc comparison (P<0.05). Significant differences were found for weight gain, however, for feed conversion and carcass yield there were no significant differences between treatments.
