摘 要:试验旨在研究含有不同比例的白花三叶草(Trifolium repens Linn)配合饲料对草金鱼(Goldfish)生长及诱食活性的影响。选取体质量约10 g杂食性淡水鱼类——草金鱼(Goldfish)作为试验对象,采用摄食率法和迷宫法作为试验方法,将白花三叶草粉分别按5%、10%、20%的比例替代鱼粉、豆粕粉和小麦粉,2周后,研究草金鱼生长情况以及诱食活性的变化。结果表明:试验组的增重率和特定生长率明显提高且饲料系数明显降低,其中以20%白花三叶草添加量的饲料效果最为明显,增重率提高了88.09%,饲料系数降低了50.48%.此外,10%和20%白花三叶草添加量的饲料对草金鱼的诱食作用均为显著(P<0.05)。由此可见,含有白花三叶草的水产配合饲料不会影响草金鱼的正常生长,且可有效的降低饲料的成本。This experiment is aimed at studying the impact on Goldfish about the mixed feed which in different proportions of Trifolium repens Linn. Choose the omnivore-fish--Goldfish which weights 10g as the experimental subject, using the feeding rate method and maze method as the experimental method.In experimental group, the proportion of the Trifolium repens Linn are 5%, 10% and 20% respectively. To study the growth and the activity of pH agostimulant of Goldfish in the last 2 weeks. The results shows that: the weight gain rate and the special growth rate of the experimental group was significantly increased while the feed coefficient decreased. What's more, feedstuff that contain 20% of the Trifolium repens are most obviously, the weight gain rate has increased 88.09% and the feed coefficient has decreased 50.48%. In addition, feedstuff that contain 10% and 20% amount of Trifolium repens performed the most significant impact of an attractant activity(P〈0.05). Thus it can be seen that the mixed feed will not impede the development of Goldfish and can also effectively help to reduce the cost.
