This study was conducted to determine the influence of substitution of fish meal with dried mealworm (Tenebrio molitor) larvae on growth performance, nutrient digestibility, blood profiles and fecal noxious gas emission in weaned pigs. A total of 240 crossbred weaned pigs [(Yorkshire × Landrace) × Duroc] at 22 d of age with an average body weight (BW) of 6.90 ± 0.03 kg were randomly allocated into 3 treatments with 8 replicates per treatment and 10 pigs per replicate (pen) according to BW. Dietary treatments included: 1) CON, basal diet with 2% fish meal; 2) T1, basal diet with 1% fish meal and 1% dried mealworm (Tenebrio molitor); T2, basal diet with 2% dried mealworm (Tenebrio molitor). During d 0-7, weaned pigs fed T2 diet had higher (P < 0.05) feed-to-gain ratio (F/G) than those fed CON and T1 diets. During d 8-21, feeding T1 diet decreased (P < 0.05) average daily gain (ADG) compared with CON diet and a quadratic effect on F/G was observed (P < 0.05). During d 0-35, ADG and final BW in T1 treatment was lower (P < 0.05) than that in CON. The apparent total tract digestibility of nitrogen in T1 treatment was lower compared with CON. Dietary treatments did not affect (P > 0.05) red blood cells, white blood cells, lymphocyte, total protein, blood urea nitrogen, insulin-like growth factor or immunoglobulin G and fecal ammonia, hydrogen sulfide or total mercaptans emission. Taken together, the dried mealworm (Tenebrio molitor) larvae did not outperform the fish meal in this study.

这项研究旨在确定用干粉虫（Tenebrio molitor）幼虫代替鱼粉对断奶猪的生长性能，营养消化率，血液分布和粪便有害气体排放的影响。将22天龄，平均体重（BW）为6.90±0.03千克的240头断奶断奶仔猪（（约克郡×长白）×杜洛克）随机分配到3个处理中，每个处理8个重复，每个重复10头（笔）根据体重。饮食治疗包括：1）CON，基础饮食加2％鱼粉；2）T1，以1％鱼粉和1％干粉虫（黄粉虫）为基础的饮食；T2，含2％干粉虫（黄粉虫）的基础饮食）。在第0-7天期间，饲喂T2日粮的断奶猪的饲料增重比（F / G）高于CON和T1日粮的猪。在第8-21天期间，与CON饮食相比，T1饮食喂养的日平均增重（ADG）降低（P <0.05），并且对F / G的影响呈二次方（P <0.05）。在第0-35天期间，T1治疗的ADG和最终BW较CON降低（P <0.05）。与CON相比，T1处理中的表观总氮消化率要低。饮食治疗不影响（P> 0.05）红细胞，白细胞，淋巴细胞，总蛋白，血尿素氮，胰岛素样生长因子或免疫球蛋白G和粪便氨，硫化氢或总硫醇排放。综上所述，在本研究中，干粉虫（黄粉虫）幼虫的表现不及鱼粉。
