中文摘要:
      本文旨在研究脱脂黑水虻幼虫粉替代鱼粉对黄颡鱼幼鱼生长性能、养分沉积率、血清生化指标和消化酶活性的影响。选用初均重为1.67±0.01g的黄颡鱼幼鱼480尾,随机分为4个处理组,分别投喂鱼粉基础料(T0)和脱脂黑水虻虫粉替代鱼粉的20% (T20)、40%(T40)和60%(T60)试验料,每个处理组3个重复,每个重复40尾鱼。养殖8周。结果表明:随着脱脂黑水虻虫粉替代量的增加,黄颡鱼生长呈现先增加后降低的趋势,T20组的末均重、增重率和特定生长率最高,且显著高于T60组(P<0.05),饲料系数最低;试验组T20和T60的摄食量显著高于对照组和T40组(P<0.05)。随着脱脂虫粉替代量的增加,试验组的腹脂指数、灰分和钙沉积率呈下降趋势,其中T60组的腹脂指数、T40和T60组的灰分和钙沉积率显著低于对照组(P<0.05),肥满度、脏体比、肝体比、肠体比和胃体比,蛋白质、脂肪和磷沉积率及黄颡鱼体蛋白、体脂肪和灰分与对照组没有差异(P>0.05)。与对照组T0相比,试验组的血清胆固醇和甘油三脂显著降低(P<0.05),高密度/低密度脂蛋白胆固醇显著升高(P<0.05),试验组T40的胃蛋白酶活力有增加趋势(P=0.068)、肠道胰蛋白酶活力显著增加(P<0.05)。在本试验条件下,脱脂黑水虻虫粉替代鱼粉不影响黄颡鱼幼鱼的生长性能和体组成含量,但可降低腹脂指数、血清甘油三酯、胆固醇含量及灰分、钙的沉积率和增加蛋白酶活力,以20%替代比例生长最佳,且优于对照组。
英文摘要:
      A 56-d feeding trial with 480 yellow catfish (Pelteobagrus fulvidraco) juveniles (1.67±0.01 g initial body weight) was carried out to estimate the effect of replacing fish meal with defatted black soldier fly larvae meal (DBSFLM) on growth performance, nutrient retention, serum biochemical parameters and digestive enzymes activity of juvenile Pelteobagrus fulvidraco. Fish were randomly allocated into four isolipidic and isoprotein dietary treatments which were formulated by replacing 0 (T0), 20% (T20), 40% (T40) and 60% (T60) of fish meal (FM) protein with DBSFLM. Each treatment was randomly assigned to triplicate groups of 40 fish per aquarium. Fish were fed twice daily to apparent satiation. With increasing content of DBSFLM, the final body weight (FBW), weight gain rate (WGR) and specific growth rate (SGR) of yellow catfish was increased at first and then decreased. Gowth performance of FBW, WGR and SGR in T20 were highest (P < 0.05) and higher (P < 0.05) than T60, whereas the feed conversion rate was the lowest (P < 0.05). The feed intake in T20 and T60 was higher (P < 0.05) than that in control and T40 groups. With the increasing content of DBSFLM, the intraperitoneal fat index (IFI) was declining with T60 group was lower (P < 0.05) than control, ash, calcium retention declining with T40 and T60 group lower (P < 0.05) than control . There was no difference of condition factor, viscera index, hepatosomatic index, intestine index and gastric index among treatments. Nutrient retention such as protein,lipid and phosphorus, moisture, crude protein, lipid and ash in whole body were not affected by dietary treatments. Compared with control, the serum cholesterol and triglyceride were reduced (P < 0.05) and the high density/low density lipoprotein cholesterol were increased (P < 0.05) in T20, T40 and T60 groups and pepsase (P = 0.068)and intestinal trypsin (P < 0.05) increase in T40 group. Results suggested that the growth performance and body composition of yellow catfish juveniles was not affected by dietary DBSFLM and the optimal alternative ratio was 20%,which was better than control. The replacement of fish meal with DBSFLM may reduce IFI, serum triglyceride, cholesterol and ash, calcium retention and increase protease.
