Fruit wastes have been considered as environmental pollution. Jackfruit is a good source of nutrients and bioactive compounds, meaning that its use in animal feed could contribute to waste reduction. The objective of this research was to evaluate the different parts of jackfruit (seed, pulp, and peel) as an agro-industrial waste on the productive parameters, carcass traits, and meat quality of rabbits. For this study, 144 thirty-five-day-old rabbits were randomly divided into four treatments, control (C), 2.5% pulp powder (PY), 2.5% seed powder (SY), and 2.5% peel powder (CY), with six repetitions and 6 rabbits for each repetition. The fattening period was 30 days. The best feed conversion ratios were found in the C, PY, and CY groups ( < 0.05). The highest chilled carcass yield was observed in the PY group ( < 0.05). Similar results were observed for intestinal morphology in all treatments ( > 0.05). The meat color obtained from the PY group had higher whiteness, redness, and chroma values ( < 0.05). Higher taste and general acceptability values for meat were observed in the groups using jackfruit (SY, PY, and CY). It is concluded that the addition of jackfruit peel powders can be used in rabbit feed, as they improve the final weight, feed conversion, carcass yield, and meat texture, while the sensory analysis demonstrates that the meat is well accepted by consumers.
水果废弃物一直被视为环境污染源。菠萝蜜是营养物质和生物活性化合物的良好来源，这意味着将其用于动物饲料有助于减少废弃物。本研究的目的是评估菠萝蜜的不同部分（种子、果肉和果皮）作为农业工业废弃物对兔子生产性能参数、胴体性状和肉质的影响。在本研究中，144只35日龄的兔子被随机分为四个处理组，对照组（C）、2.5%果肉粉组（PY）、2.5%种子粉组（SY）和2.5%果皮粉组（CY），每组6个重复，每个重复6只兔子。育肥期为30天。在C组、PY组和CY组中发现了最佳的饲料转化率（P<0.05）。在PY组中观察到最高的冷胴体产量（P<0.05）。所有处理组的肠道形态均观察到相似的结果（P>0.05）。从PY组获得的肉色具有更高的白度、红度和色度值（P<0.05）。在使用菠萝蜜的组（SY组、PY组和CY组）中，肉的口感和总体可接受性值更高。得出的结论是，添加菠萝蜜果皮粉可用于兔子饲料，因为它们能提高最终体重、饲料转化率、胴体产量和肉质，同时感官分析表明肉很受消费者欢迎。
