This experiment was to investigate ginger extract on production performance, antioxidant ability and immunity of laying hens. A total of 600 Hy-Line brown laying hens aged at 25 wk old were randomly divided into 2 treatments, 4 replicates per treatment, 75 layers each replicate. The control group hens were fed a basal diet; the experimental group hens were fed basal diets with 0.1% ginger extract. The results were shown as follows: 1) ginger extract significantly enhanced laying rates ( < 0.05) and daily egg weight ( < 0.05), substantially reduced the ratio of feed to egg ( < 0.05) of the hens; 2) ginger extract did not change the activities of glutathione peroxidase (GSH-PX) and total antioxidant capacity (TAOC) but significantly improved plasma superoxide dismutase (SOD) activity ( < 0.05), reduced malondialdehyde (MDA) content ( < 0.05) of the birds; 3) ginger extract did not affect the contents of serum total protein (TP), albumin (ALB), globulin (GLB), but significantly increased lysozyme (LZM) activity ( < 0.05); 4) ginger extract also significantly reduced plasma prostaglandin E (PGE) content ( < 0.05). This study shows that ginger extract not only can improve the birds' antioxidant capacity, enhance immune function, but also has a potential of reducing inflammatory response.
本试验旨在研究生姜提取物对蛋鸡生产性能、抗氧化能力和免疫力的影响。选取600只25周龄的海兰褐蛋鸡，随机分为2组，每组4个重复，每个重复75只鸡。对照组饲喂基础日粮；试验组饲喂添加0.1%生姜提取物的基础日粮。结果如下：1）生姜提取物显著提高了蛋鸡的产蛋率（<0.05）和日产蛋量（<0.05），显著降低了料蛋比（<0.05）；2）生姜提取物对谷胱甘肽过氧化物酶（GSH-PX）和总抗氧化能力（TAOC）活性无显著影响，但显著提高了血浆超氧化物歧化酶（SOD）活性（<0.05），降低了丙二醛（MDA）含量（<0.05）；3）生姜提取物对血清总蛋白（TP）、白蛋白（ALB）、球蛋白（GLB）含量无显著影响，但显著提高了溶菌酶（LZM）活性（<0.05）；4）生姜提取物还显著降低了血浆前列腺素E（PGE）含量（<0.05）。本研究表明，生姜提取物不仅能提高蛋鸡的抗氧化能力，增强免疫功能，还具有减轻炎症反应的潜力。
