研究了不同饲料组成对花刺参生长的影响。实验采用50%自配饲料+50%蛎壳粉(A)、50%自配饲料+40%蛎壳粉+10%海泥(B)、50%自配饲料+30%蛎壳粉+20%海泥(C)、50%自配饲料+20%蛎壳粉+30%海泥(D)、50%自配饲料+10%蛎壳粉+40%海泥(E)、50%自配饲料+50%海泥(F)和自制配合饲料(G)7种饲料投喂花刺参,进行了为期90天的养殖实验。实验结果显示,B组的特定生长率最高,饲料系数最低;A组和C组次之;D组、E组、F组和G组的投喂效果不理想。研究表明降低饲料中海泥的比例,适当提高蛎壳粉的比例,有利于提高花刺参饲料的适口性,促进花刺参生长。
The effects of different feed compositions on the growth of S. cuneata were studied. 50% self-formulated feed + 40% oyster shell powder + 10% marine mud (B), 50% self-formulated feed + 30% oyster shell powder + 20 50% Self-Contained Feed + 20% Oyster Shell Powder + 30% Sea Mud (D), 50% Self-Contained Feed + 10% Oyster Shell Powder + 40% Sea Mud A total of 90 days of culture experiments were conducted by feeding 7 kinds of fodder with 7 kinds of feed including 50% sea mud (F) and homemade compound feed (G). The experimental results showed that the specific growth rate of group B was the highest, the feed coefficient was the lowest, followed by group A and group C, and the effects of group D, group E, group F and group G were not satisfactory. Studies have shown that reducing the proportion of feed in the mud, the appropriate increase in the proportion of oyster shell powder, help to improve the palatability of the feed palatability, and promote the growth of needle flowers.
