黄粉虫粪和蚕沙的常规营养成分分析

Analysis on the Conventional Nutrients in Tenebrio molitor Manure and Silkworm Excrement

采用饲料常规养分分析方法对黄粉虫粪和蚕沙非常规饲料样品中的干物质、粗蛋白质、粗脂肪、粗灰分、钙和磷含量进行测定,并将黄粉虫粪与玉米粉、鱼粉,蚕沙与玉米粉、豆粕的营养成分进行比较。结果表明:黄粉虫粪粗灰分比鱼粉低,显著高于玉米粉;粗蛋白含量显著低于鱼粉,但显著高于玉米粉;粗脂肪含量显著低于鱼粉;钙含量比玉米粉和鱼粉均高;磷含量显著高于鱼粉和玉米粉;干物质含量显著低于鱼粉。蚕沙粗灰分含量显著高于豆粕和玉米粉;粗蛋白含量显著高于玉米粉,低于豆粕;粗脂肪含量显著高于豆粕;钙含量显著高于玉米粉和豆粕;磷含量显著低于豆粕;干物质含量均显著高于玉米粉和豆粕。

The contents of several conventional nutrients,including dry matter,crude protein,crude ash,Ca and P,in Tenebrio molitor manure and silkworm excrement were measured,and then compared with that of corn flour,fish meal and soybean meal.The result indicated that,in Tenebrio molitor manure,its crude ash content was less than that of fish meal,whereas significantly higher than that of corn flour;its crude protein content was obviously less than that of fish meal,but significantly higher than that of corn flour;its crude fat content was significantly lower than that of fish meal,but its Ca and P contents were both higher than that of fish meal and corn flour;its dry matter content was significantly lower than that of fish meal.In the silkworm excrement,its crude ash content of was significantly higher than that of soybean meal and corn flour;its crude protein content was higher than that of corn flour,but lower than that of soybean meal;its crude fat content was obviously higher than that of soybean meal;its Ca content was significantly higher than that of corn flour and soybean meal,but its P content was greatly less than that of soybean meal;its dry matter content was obviously higher than that of both corn flour and soybean meal.
