摘要: 蚕沙是桑蚕产业的副产物,具有产量丰富和价格低廉,富含粗蛋白质、粗纤维、粗脂肪等常规营养成分及钙、磷、铜、铁、锌、锰等矿物元素,同时含有黄酮、多酚、维生素、生物碱等活性成分的特点,可作为一种优质的非常规饲料原料。然而,蚕沙中含有大量微生物、纤维素、亚硝酸盐、单宁、果胶、植酸等有毒有害或抗营养物质,直接饲喂会对动物健康产生消极影响,这严重限制了蚕沙的饲料化利用。采用一些技术手段,特别是微生物发酵技术不仅可降解蚕沙中的果胶、纤维素、亚硝酸盐、木质素、植酸、单宁等抗营养物质,抑制有害微生物的繁殖,而且还能提高其粗蛋白质、粗脂肪等营养物质含量,进而改善蚕沙的营养结构和营养价值,这对推进蚕沙的饲料化利用和缓解中国饲料资源紧缺等问题意义重大。在动物生产中,饲粮中适宜的蚕沙添加或替代水平具有提高动物生产性能、改善动物产品品质、调控机体免疫和代谢等作用,在畜牧领域具有广泛的发展应用前景。作者就蚕沙的营养特点和组成成分、处理工艺,以及蚕沙在动物生产中的应用进行归纳总结,以期为蚕沙的饲料化利用提供参考。

Abstract: Silkworm excrement,a by-product of the sericulture industry,possesses a plethora of conventional nutrients such as crude protein,crude fiber,and crude fat,as well as essential minerals including calcium,phosphorus,copper,iron,zinc,and manganese.Additionally,this by-product contains valuable bioactive compounds such as flavonoids,polyphenols,vitamins,and alkaloids.Due to its abundant production and cost-effectiveness,silkworm excrement can serve as a high-quality unconventional feed ingredient.However,silkworm excrement includes a substantial amount of microorganisms,cellulose,nitrites,tannins,pectin,phytic acid,and other toxic,harmful,or anti-nutritional substances,which can adversely impact animal health when consumed directly.Consequently,this greatly hampers the potential utilization of silkworm excrement as feed.By implementing various technical approaches,especially microbial fermentation technology,it is possible not only to degrade pectin,cellulose,nitrites,lignin,phytic acid,tannins,and other anti-nutritional substances present in silkworm excrement but also to inhibit the proliferation of harmful microorganisms.Moreover,this process can enhance the content of crude protein,crude fat,and other nutritional substances,subsequently improving the nutritional structure and value of silkworm excrement.As a result,this bears great significance in promoting the feed utilization of silkworm excrement and alleviating the scarcity of feed resources in China.Within animal production,the appropriate inclusion or substitution of silkworm excrement in animal diets has been proven to enhance animal performance,improve the quality of animal products,and regulate the immune system and metabolism of the animal.This suggests that integrating silkworm excrement into animal feed holds promising prospects for development and application in the field of animal husbandry.The authors summarized the nutritional characteristics,compositional constituents,and processing methods of silkworm excrement,along with its application in animal production,aiming to provide a reference for the utilization of silkworm excrement as feed.

Key words: silkworm excrement; nutritional characteristics; fermentation processing; dry processing; animal production
