摘  要：
以初始体重(19.55±0.15)g的黄鳝(Monopterus albus)为研究对象,用膨化豆粕分别替代基础饲料(含55%鱼粉)中0、12%、24%、36%和48%的鱼粉,配制膨化豆粕含量分别为0(对照)、9.3%、18.6%、28.0%和37.2%的5种等氮等脂的试验饲料,研究其对黄鳝生长性能、体成分、肠道消化酶活力及血清生化指标的影响,养殖试验持续90 d。每种饲料设3个重复,每个重复饲养黄鳝100尾。结果表明:与对照组相比,当膨化豆粕含量大于18.6%时,黄鳝的增重率,机体粗脂肪含量,血清葡萄糖含量,肠道脂肪酶、淀粉酶活力及肌肉中必需氨基酸含量、必需氨基酸/总氨基酸显著下降(P<0.05),饲料系数显著升高(P<0.05);当膨化豆粕含量达到37.2%时,血清尿素氮含量显著升高(P<0.05)。随着饲料中膨化豆粕含量的升高,肠道胰蛋白酶活力呈先上升后下降的趋势,血清谷草转氨酶活力呈下降趋势,而血清谷丙转氨酶活力呈上升趋势。综上所述,以膨化豆粕替代鱼粉,黄鳝配合饲料中膨化豆粕的含量以不超过18.6%为宜。

摘  要：
A 90-day feeding trial was conducted to investigate the effects of fish meal( FM) replacement by different proportions of extruded soybean meal on growth performance,body composition,intestinal digestive enzyme activities and serum biochemical indices of rice filed eels( Monopterus albus) [initial average body weight of( 19.55 ± 0.15) g]. Five isonitrogenous and isolipidic diets were formulated to contain 0( control),9.3%,18.6%,28.0%,37.2% extruded soybean meal which replaced 0,12%,24%,36% and 48% FMin the basal diet( contained 55% FM),respectively. Each diet had three replicates,and each replicate had 100 rice filed eels. Results showed as follows: compared with control group,the weight gain rate,body crude lipid content,serum glucose content,intestinal lipase and amylase activities,and essential amino acid content and essential amino acid / total amino acid in muscle were significantly reduced( P< 0.05),but feed conversion rate was significantly increased( P< 0.05); when dietary extruded soybean meal content was more than 18.6%,the content of serum urea nitrogen was significantly reduced when dietary extruded soybean meal content arrived at37.2%( P< 0. 05). W ith the dietary extruded soybean meal content increasing,the intestinal trypsin activity was firstly increased and then decreased,but the serum glutamic oxaloacetic transaminase activity showed an decrease trend and the glutamic-pyruvic transaminase activity showed an increase trend. In conclusion,extruded soybean meal in the diet of rice field eels is not more than 18.6% when FMreplacement by extruded soybean meal.
