In Experiment 1, a total of eighteen crossbred ([Landrace × Yorkshire] × Duroc) barrows with an initial body weight of 6.74 ± 0.68 kg were randomly divided into three dietary treatments (one pig per cage and six replicates per treatment) and housed in metabolic cages that were equipped with a feeder and slatted floor to collect urine and feces. In Experiment 2, a total of 96 crossbred ([Landrace × Yorkshire] × Duroc) barrows with an initial body weight of 8.25 ± 0.42 kg were used in the 6-week trial. The pigs were randomly divided into three dietary treatments (three pigs per pen and eight replicates per treatment). In Experiment 1, nutrient composition of defatted black soldier fly larvae meal (BLM) was superior to that of hydrolyzed BLM but lower than that of fish meal (FM). Also, defatted BLM and FM had better apparent total track digestibility (ATTD) of crude protein (CP) and better nitrogen retention ( < 0.05) than hydrolyzed BLM, but there was no significant difference ( > 0.05) between defatted BLM and FM. In Experiment 2, defatted BLM improved ( < 0.05) average daily gain (ADG), feed conversion ratio (FCR), and feed cost per kg gain (FCG) compared with FM. Defatted BLM could replace soybean meal and fish meal as an alternative protein source for weaning pigs.
在实验1中，总共18头初始体重为6.74±0.68千克的杂交（[长白猪×大白猪]×杜洛克猪）公猪被随机分为三种日粮处理组（每笼一头猪，每组六个重复），并饲养在配备有喂食器和板条地板以收集尿液和粪便的代谢笼中。在实验2中，总共96头初始体重为8.25±0.42千克的杂交（[长白猪×大白猪]×杜洛克猪）公猪用于为期6周的试验。这些猪被随机分为三种日粮处理组（每栏三头猪，每组八个重复）。在实验1中，脱脂黑水虻幼虫粉（BLM）的营养成分优于水解黑水虻幼虫粉，但低于鱼粉（FM）。此外，脱脂黑水虻幼虫粉和鱼粉的粗蛋白（CP）表观总肠道消化率（ATTD）更好，氮保留率也更好（P<0.05），高于水解黑水虻幼虫粉，但脱脂黑水虻幼虫粉和鱼粉之间没有显著差异（P>0.05）。在实验2中，与鱼粉相比，脱脂黑水虻幼虫粉提高了（P<0.05）平均日增重（ADG）、饲料转化率（FCR）和每千克增重的饲料成本（FCG）。脱脂黑水虻幼虫粉可以替代豆粕和鱼粉，作为断奶仔猪的替代蛋白质来源。
