Abstract

This study aimed to evaluate the in sacco nutrient degradability of total mixed ration (TMR) silage containing intact and defatted black soldier fly (BSF) larvae. The study evaluated four dietary treatments and six replications. The treatments consisted of control TMR silage without BSF larvae (R1), 20% intact BSF larvae + 80% TMR silage (R2), 20% chemically defatted BSF larvae + 80% TMR silage (R3), and 20% mechanically defatted BSF larvae + 80% TMR silage (R4). Samples were placed in polyester bags and incubated in the rumen in sacco up to 72 h. Nutrient degradability was evaluated for each time point interval. Results revealed that the lowest dry matter degradability (DMD) was found in R1 compared to all treatments (p < 0.05), while the highest DMD was found in R2 (p < 0.05). The highest organic matter degradability was found in R2 compared to R1, R3 and R4 (p < 0.05). Addition of BSF larvae to TMR silage increased the crude protein degradability (p < 0.05). In conclusion, inclusion of both intact and defatted BSF larvae into TMR silage did not have any adverse effects on nutrient profiles and showed a good nutrient degradation values in the rumen.

含完整和脱脂黑兵蝇幼虫的青贮在甘蔗中的养分降解率

本试验旨在评价含完整和脱脂黑兵蝇(BSF)幼虫的全混合日粮(TMR)青贮饲料在蔗渣中营养物质的降解率。该研究评估了四种饮食治疗方法和六次重复。分别饲喂不含BSF幼虫的TMR青贮(R1)、20%完整BSF幼虫+ 80% TMR青贮(R2)、20%化学脱脂BSF幼虫+ 80% TMR青贮(R3)和20%机械脱脂BSF幼虫+ 80% TMR青贮(R4)。将样品放入聚酯袋中，在瘤胃中用囊液孵育72 h。在每个时间点间隔内评估养分降解率。结果表明，R1处理的干物质降解率(DMD)最低(p < 0.05)， R2处理的DMD最高(p < 0.05)。与R1、R3和R4相比，R2的有机物降解率最高(p < 0.05)。在TMR青贮饲料中添加BSF幼虫可提高粗蛋白质降解率(p < 0.05)。综上所述，在TMR青贮中加入完整的和脱脂的BSF幼虫对营养成分没有任何不良影响，并且在瘤胃中具有良好的营养降解价值。

期刊介绍： Journal of the Indonesian Tropical Animal Agriculture (JITAA) is a double blind peer-reviewed publication devoted to disseminate all information contributing to the understanding and development of animal agriculture in the tropics by publication of original research papers. The journal covers all aspect relating to Animal Agriculture, including: -Animal breeding and genetics -Animal feeding and nutrition -Animal reproduction -Animal biotechnology -Animal physiology -Animal production and technology -Animal products technology -Animal management and economics -Animal products processing and animal by-products -Animal microbiology -Livestock farming systems -Other related topics in relation to animal science. The topics of research are not only on Indonesian tropical animal agriculture, but also on other tropical regions of the world.
