| 摘要: |
| 将海带粉、扇贝边粉、豆粕、虾粉、马尾藻粉按照40∶18∶20∶7∶15的配比混合，经浸泡、研磨等预处理后，加入0.25%~0.5%的水产诱食酵母，发酵72 h。SDS-PAGE凝胶电泳结果显示，经过发酵处理后，饲料中的大分子蛋白发生降解。按照刺参体重3%的投喂量进行为期50d的投喂实验，结果表明，发酵饲料组刺参的生长明显优于普通饲料组（未发酵饲料），可见发酵饲料能够更好地满足刺参健康、快速生长的需要，具有良好的市场潜力。 |

| The production and feeding experiment of fermented feed in pond culture system of sea cucumber, Apostichopus japonicus |

| Abstract: |
| In order to develop feeds that can improve the nutrient absorption and health of sea cucumber, and reduce the incidence of disease, a kind of fermented feed was developed. Ratio of raw materials was 40∶18∶20∶7∶15 (kelp powder∶scallop skirt powder∶soybean meal∶shrimp meal∶sargassum powder). The processing procedure was as follows: the raw materials were mixed according to the ratio, fully immersed and ground, then 0.25%~0.5% of yeast products were added and the mixture was fermented for 72 h. The result of SDS-PAGE showed that high molecular weight protein was degraded into small molecular weight polypeptide during fermentation. During the 50-day feeding trial, the sea cucumber was fed with fermented feed and regular feed (unfermented) respectively. The feeding ratio was 3% of body weight. The result showed that the growth of sea cucumber fed with the fermented feed was significantly better than the regular feed after 50 days feeding trial. It is clear that the fermented feed is better than the regular feed and it can much better meet the need of health and rapid growth of sea cucumber, thus has good market potential. |
