慈竹纤维添加对福寿螺生长速率的影响

Effect of Bamboo(Neosinocalamus affinis)Fiber on the Growth Rate of Pomacea canaliculata

福寿螺蛋白质含量丰富且营养成分高,若能将其高效转化植物纤维的能力运用在慈竹上,对增加竹子利用途径、促进竹产业发展具有重要的现实意义。本研究采用一次回归正交设计的试验研究方法,测定饵料中添加慈竹纤维含量对福寿螺生长速率的影响。结果表明,当福寿螺饵料中慈竹纤维含量达到50%时,其生长速度显著增加,体重增长率最高可达85.5%。福寿螺体重增长率主要由慈竹纤维、豆粕、玉米粉共3种处理效应构成,慈竹纤维添加在饵料中对福寿螺体重增重率的贡献最大,并达到极显著水平(P<0.01),增重率Y与慈竹纤维X1、豆粕X2、玉米粉X3的回归方程式为Y=13.862X1+8.988X2+5.237X3+55.358。此研究结果为竹纤维向动物蛋白转化提供了理论基础,对竹纤维的饲料化利用具有重要参考价值。

Pomacea canaliculata is rich in protein and high in nutritional content.If the ability to efficiently transform fiber into animal protein can be applied to bamboo resources,it is of important practical significance to increase bamboo utilization ways and promote the development of bamboo industry.In this study,the regression orthogonal design was used to determine the effect of adding bamboo(Neosinocalamus affinis)fiber content in bait on the growth rate of P.canaliculata.The results showed that when the bamboo fiber content in the bait reached 50%,the growth rate of P.canaliculata increased significantly,and its weight growth rate could reach 85.5%.The growth rate of P.canaliculata was mainly composed of three treatment effects:N.affinis fiber,soybean meal and corn flour.The addition of N.affinis fiber to bait had the largest contribution to the weight gain rate of P.canaliculata,and reached the significant level(p<0.01).The regression equation for the weight rate Y and N.affinis fiber X1,soybean meal X2,and corn flour X3 was Y=13.862X1+8.988X2+5.237X3+55.358.The results of this study provided a theoretical basis for the transformation of bamboo fiber into animal protein,and had important reference values for the feed utilization of bamboo fiber.
