Fermented silkworm pupae (SWP) silage or untreated fresh SWP pastes were incorporated in carp feed formulations replacing fishmeal. The feed formulations were isonitrogenous (30.2-30.9% protein) and isocaloric (ME = 2905-2935 kcal/kg). Feeding under a polyculture system consisting of 30% each of catla (Catla catla), mrigal (Cirrhinus mrigala) and rohu (Labeo rohita) with 10% silver carps (Hypophthalmychthys molitrix) was carried out in ponds to evaluate the nutritive quality of SWP silage. Survival rate, feed conversion ratio and specific growth rate, respectively, were 84.2%, 2.10 and 2.39 for fermented SWP silage, 65.8%, 2.98 and 2.26 for untreated SWP and 67.5%, 3.16 and 2.20 for fishmeal indicating clearly that the fermented SWP silage was nutritionally superior to untreated SWP or fishmeal. The dietary influence on the proximate composition of whole fish was marginal.
将发酵蚕蛹（SWP）青贮饲料或未处理的新鲜SWP糊状物添加到鲤鱼饲料配方中，替代鱼粉。饲料配方的粗蛋白含量相同（30.2 - 30.9%）且热量相同（代谢能 = 2905 - 2935千卡/千克）。在池塘中采用由30%的印度鯝（印度鯝）、30%的麦瑞加拉鲮（麦瑞加拉鲮）、30%的印度魮（印度魮）和10%的白鲢（Hypophthalmychthys molitrix）组成的混养系统进行投喂，以评估SWP青贮饲料的营养质量。发酵SWP青贮饲料组的存活率、饲料转化率和特定生长率分别为84.2%、2.10和2.39；未处理SWP组分别为65.8%、2.98和2.26；鱼粉组分别为67.5%、3.16和2.20，这清楚表明发酵SWP青贮饲料在营养上优于未处理的SWP或鱼粉。日粮对全鱼的近似成分影响很小。
