摘要
为了研究海藻提取物对优质型青脚麻鸡免疫器官组织形态学的影响，试验选取1800只1日龄优质型青脚麻鸡为试验动物进行饲养试验。试验鸡群随机分为2组，每组3个重复。在饲养过程中。对照组饲喂基础饲粮；试验组饲喂基础饲粮＋海藻提取物300rag／kg。在49日龄时．每个重复组随机抽样30只解剖，摘取法氏囊和脾脏进行称重，并进行法氏囊、脾脏和胸腺中的T、B淋巴细胞检查。结果表明：试验组的脾脏重和法氏囊重均高于对照组（P〈0．05）：试验组免疫器官中的T和B淋巴细胞相对数量均显著高于对照组（P〈0．05）。结论：海藻提取物具有显著促进优质型青脚麻鸡的法氏囊和脾脏发育、明显增加免疫器官中T和B淋巴细胞相对数的作用。
The feeding test was conducted to evaluate the effect of seaweed PE on immune or- gans and technology of syan shank partridge chicken. 1800 syan shank partridge chickens were randomly assigned to 2 groups, each group had 3 repeats. Control group was provided with basic diet, while test group was fed with basic diets added seaweed PE for 49 days. The results showed that the test group was significant different in comparing spleen and bursal weight （P 〈 0. 05 ） , the number of T- lymphocytes and B- lymphocytes were much better than control group （P〈0.05）. The conclusion of the study was that seaweed PE could effectively improve immune function of immune organs.
