摘要
从大蒜中提取大蒜油，配以从多种中草药中提取的皂甙类天然活性物质，组成复方制剂，以０．２％的比例添加于对虾饲料中，对中国对虾（Ｐｅｎａｎｅｕｓｃｈｉｎｅｎｓｉｓ）体液免疫功能和提高防病能力的作用进行研究．结果表明，对虾血细胞吞噬率、杀伤率和吞噬指数有极显著提高（Ｐ＜０．０１），血细胞杀伤指数显著提高（Ｐ＜０．０５）；对虾血淋巴中的溶菌活力极显著提高（Ｐ＜０．０１），酚氧化酶活力显著提高（Ｐ＜０．０５）；溶藻弧菌攻毒后，对虾免疫保护率提高８６％（Ｐ＜０．０１）．该添加剂经对虾口服后，可显著提高其免疫功能。
A garlic oil compound was made from garlic oil and some herb derived biologically active substances such as saponins. The compound was added at 0.2% into a feed as an additive to evaluate its effectr on humaral immunity in Penaeus chinensis , Results showed that the rate of phagocytosis ,the rate of killing and phagocytic index of haemocytes increased with great significance ( P <0.01);the killing index of haemocytes increased significantly ( P <0.05);the bacteriolytic activity of haemolymph increased with great significance (P <0.01).The phenoloxidase activity of haemolymph increased with significance at P< 0.05.In a challenge experiment with vibro alginolyticus , the immune protective rate was increased by 86% ( P <0.01).Oral administration of the additive could significantly increase the immune function in Penaeus chinensis , and effectively protect the shrimp from infection with vibro.
