摘要 

[目的]为研究橡胶籽油替代不同比例豆油对虹鳟幼鱼生长、血液及肝脏生化指标的影响。[方法]以橡胶籽油添加量分别为0%、4%、8%和12%替代相应的豆油,配制4种等氮等能饲料进行10周养殖试验。[结果](1)随着替代比例的升高,虹鳟末重、体增重、日增重系数和蛋白质效率均呈先上升后下降的趋势,以8%组最高(P<0.05);相反,8%组饲料系数最低。(2)随着替代比例的升高,血清低密度脂蛋白胆固醇水平呈先上升后下降的趋势,以8%组最高;而LDL-C/HDL-C值呈上升的趋势,12%组显著高于0%组。(3)随着替代比例的升高,血浆一氧化氮含量和肝脏碱性磷酸酶活性显著升高,血浆过氧化氢酶活性显著降低。(4)0%组血浆氨氮含量显著低于其他组。不同处理组血浆总蛋白、总氨基酸、尿素氮、钙和磷含量、谷丙转氨酶活性及肝脏ALT、谷草转氨酶活性均无显著差异(P>0.05)。[结论]饲料中添加4%~12%橡胶籽油明显提高虹鳟生长性能和饲料利用率,对虹鳟脂质代谢和抗氧化能力无明显不良影响,且虹鳟饲料中橡胶籽油适宜添加量为8%。

Abstract

[Purposes] This experiment was conducted to study the effects of replacement of soy oil by extruded rubber seed oil on growth performance, the blood and liver biochemical indexes in rainbow trout.[Method] Four isoproteic and isolipidic experimental diets were formulated with 0%,4%,8% and 12% rubber seed oil replacing graded levels of soy oil, respectively. The experiment lasted for 10 weeks.[Results] (1) With the rubber seed oil replacement level increasing, the final body weight, weight gain, daily gain coefficient and protein efficiency ratio among all groups showed a trend of first increase and then decrease, and the highest was 8% group (P<0.05),while the feed conversion rate was just opposite. The lowest was found in 8% group.(2) With the rubber seed oil replacement level increasing, the serum levels of low density lipoprotein cholesterin showed an increasing trend firstly, and then decreasing trend. And the highest was found in 8% group. The LDL-C/HDL-C in serum showed a gradual increasing trend, and it is in 12% group was significantly higher than that in 0% groups. (3) With the rubber seed oil replacement level increasing, the content of plasma nitric oxide and the activity of alkaline phosphatase were significantly increased, but the activity of plasma catalase decreased significantly. (4) The amino-N of the plasma in 0% group was significantly lower than that in the other groups. There was no significant difference in total protein, total amino acid, blood urea nitrogen, calcium, phosphorus, alanine aminotransferase activity of the plasma and ALT, aspartate aminotransferase of the liver among all groups (P>0.05).[Conclusions] In summary, 4%-12% rubber seed oil supplementation can improve the growth performance and feed utilization ratio, and there is no obvious adverse effects on antioxidant capacity and lipid metabolism of the rainbow trout. The results also indicate that the suitable supplemental level is 8% in rainbow trout diets.
