[目的]本研究旨在对香蕉茎叶进行营养成分和有毒有害物质分析,以及规模化生产的加工贮存技术研究,为香蕉茎叶的饲料开发利用提供理论指导依据。[方法]通过香蕉茎叶不同处理青贮的营养成分分析、安全性评价,以及肉牛育肥试验,探索香蕉茎叶加工调制贮存和饲喂技术。[结果]表明:新鲜香蕉茎叶DM、CP、EE、CF、NDF、ADL、NFE、Ca、P和Ash含量分别为8.69%、7.605%、1.00%、25.45%、52.28%、37.57%、32.33%、1.43%、0.2%和11.29%;不同处理香蕉茎叶青贮品质皆较好;单宁含量随着青贮时间呈递减趋势,亚硝酸盐含量随青贮时间有增加趋势,但增加幅度较小,其含量值低于国家食品中亚硝酸盐允许标准,总体来说饲用是安全的;不同处理饲喂肉牛适口性好,增重显著。[结论]香蕉茎叶青贮饲养肉牛无毒副作用,适口性好,牛只增重明显,且加工和贮存技术难度不大,易于推广和产业化开发利用。
[Objective] The aim of this study was to analyze the nutritional components and toxic and harmful substances of banana stems and leaves, as well as the processing and storage technology of large-scale production, and to provide theoretical basis for the development and utilization of banana stems and leaves. [Method] Through the analysis of nutrient content of silage in different treatment of banana stem and leaf, safety evaluation and fattening experiment of beef cattle, the processing, storage and feeding technology of banana stem and leaf processing were explored. [Result] The results showed that the contents of DM, CP, EE, CF, NDF, ADL, NFE, Ca, P and Ash in the stems and leaves of fresh banana were 8.69%, 7.605%, 1.00%, 25.45%, 52.28%, 37.57% and 32.33 %, 1.43%, 0.2% and 11.29%, respectively. The quality of silage of banana stems and leaves was better than that of other treatments. The content of tannin decreased with the time of silage and the content of nitrite increased with silage time, The content is lower than the allowable standard of national nitrite in food, and the feeding is safe in general; the palatability of beef cattle fed with different treatments is good and the weight gain is remarkable. [Conclusion] The beef cattle with banana stem and leaf silage had no toxic and side effects, good palatability and obvious weight gain. The processing and storage techniques were not difficult and could be easily popularized and industrialized.
