Rabbits’ skin is considered an excellent by-product and has several purposes, such as making clothes and artifacts in general. The aim of this study was to evaluate the effect of the inclusion of banana peel (BP) and sweet potato vines (SPV) on the length of the fur of rabbits fed different levels of these ingredients. Twenty-five New Zealand White rabbits, of both sexes, weaned at 35 days old, were randomly distributed in individual cages, in five treatments with five replications each, in a completely randomized design. The animals received one of the following diets: control (0BP+SPV) without BP and SPV; (25BP+SPV) experimental diet with 25% BP and SPV replacing maize and alfalfa hay; (50BP+SPV) experimental diet with 50% BP and SPV replacing maize and alfalfa hay; (75BP+SPV) experimental diet with 75% BP and SPV replacing maize and alfalfa hay; and (100BP+SPV) experimental diet with 100% BP and SPV replacing maize and alfalfa hay. The biological assay lasted 49 days, where food and water were provided ad libitum. At the end of the test, a portion of hair was removed from the nape, loin and thigh region to measure the length. Means were compared through analysis of variance, followed by Tukey test (0.05). The hair length results obtained showed that there were no differences between treatments. In this way, it is concluded that it is possible to completely replace maize and alfalfa hay by the combination of BP+SPV in rabbit rations, for fur generation, without changing the characteristics of the fur.
