Falcone DB, Klinger ACK, Silva SS, Adorian TJ, de Toledo GSP, da Silva LP. Can banana peel and sweet potato vines serve as efficient feed ingredients in diets for growing rabbits? Trop Anim Health Prod 2023; 55:290. [PMID: 37581724 DOI: 10.1007/s11250-023-03697-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 07/19/2023] [Indexed: 08/16/2023]
Abstract
This study aimed to evaluate the use of banana peel (BP) and sweet potato vines (SPV) as a replacement for maize and alfalfa hay in diets for rabbits. Animal performance, economic analyses, meat composition, and color were evaluated for 49 days in a total 50 New Zealand White rabbits weaned at 35 days with an average body mass of ± 614 g. The animals were allotted, in a completely randomized design, having five dietary groups: control diet (0), without banana peels and sweet potato vines, or experimental diets, 25, 50, 75, and 100-with 25%, 50%, 75%, and 100% of banana peels and sweet potato vines in substitution to maize and alfalfa hay, respectively. The data were analyzed using ANOVA, while the means were compared by Tukey test (p < 0.05). The results indicate that daily feed intake, mass gain, and feed conversion were not statistically different from one another in the test groups compared to the control group treatment. In addition, the study shows no differences were observed in centesimal compositions and muscle color. The replacement of maize and alfalfa hay by the combination of BP and SPV resulted in reduction in feed costs, reaching 50% in the experimental diet with 100% of substitution the ingredients. It can be concluded, based on the results on animal performance, meat/color composition, and economic analyses, that BP and SPV may be used as a substitute for maize and alfalfa hay up to 100% in diets for growing rabbits.

Anim Sci J 2018; 89:1556-1560.

Abstract
The use of residues as substitutes for conventional ingredients in animal feed is a promising alternative able to reduce both costs and environmental pollution. This study aimed to evaluate the viability of using sweet potato vines (SPV) as a replacement for alfalfa hay in diets for growing rabbits. The performance, carcass characteristics, meat composition and metabolic parameters of the liver were evaluated in 30 New Zealand rabbits weaned at 35 days old and an average weight of 900 g. The animals were allotted into three dietary groups: 0SPV, control diet without SPV; 50SPV, diet with 50% replacement of alfalfa hay by SPV; 100SPV, diet with 100% replacement of alfalfa hay by SPV. The animals were slaughtered at 77 days of age. The liver was collected for analysis of glucose and hepatic glycogen and meat samples were collected for analysis of the chemical composition. The data obtained were statistically compared by analysis of variance followed by the Tukey test (0.05). None of the analyzed variables presented differences. It can be concluded, therefore, that SPV may be used as a substitute for alfalfa hay up to 100% in diets for rabbits without impairing the performance and meat composition.
