Research Progress on the Nutritional Characteristics,Processing Technology and Application of Silkworm Excrement in Animal Production
摘要
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.关键词
