我国有丰富的蚕资源,每年有近10万吨蚕蛹未得到充分利用,多被用于饲料添加剂。据化验测定,普通蚕蛹的粗蛋白质含量50～60％(脱脂蚕蛹高达71～89％),粗脂肪25～26％(脱脂蚕蛹1～2.45％),粗纤维3.4～3.6％(脱脂蚕蛹6％),粗灰份3.8～5.4％(脱脂蚕蛹0.95～5.8％)。每100公斤蚕蛹粉所含蛋白质相当于85公斤瘦猪肉、98公斤鸡蛋、10公斤鲫鱼所含的蛋白质.每100公斤蚕蛹粉的脂肪含量,相当于32公斤 China has rich silkworm resources, each year nearly 100,000 tons of silkworm pupae are not fully utilized, and are mostly used as feed additives. According to laboratory tests, crude protein content of ordinary silkworm chrysalis is 50-60% (skim silkworm as high as 71-89%), crude fat 25-26% (skim silkworm 1 ~ 2.45%), crude fiber 3.4-3.6% (skim silkworm pupa 6% ), Coarse ash 3.8 ~ 5.4% (skim silk pupa 0.95 ~ 5.8%). The protein contained per 100 kg of pupa powder is equivalent to 85 kg of lean pork, 98 kg of eggs, 10 kg of protein content of crucian carp per 100 kg of pupa powder fat content, equivalent to 32 kg
