| 摘 要： | 本试验旨在研究博落回提取物对断奶仔猪生长性能、血清免疫指标及抗氧化指标的影响,选择120头35日龄的健康杜×长×大三元杂交断奶仔猪,按体重相近、性别比例相同原则随机分成2组,每组5个重复,每个重复12头猪,预饲期5 d,试验期30 d,对照组饲喂基础日粮,试验组饲喂添加0.1%博落回提取物的基础日粮。试验期间,测定每组仔猪的平均日增重（ADG）、平均日采食量（ADFI）及料重比（F/G）;在试验结束时,每个重复选取2头仔猪采血测定血清免疫指标及抗氧化指标。结果显示：①添加博落回提取物组断奶仔猪ADG较对照组提高3.89%（P>0.05）,F/G下降4.32%（P>0.05）,且腹泻率较对照组有显著降低的趋势（P=0.076）。②日粮中添加博落回提取物显著提高了断奶仔猪血清中免疫球蛋白G （IgG）和肿瘤坏死因子-α（TNF-α）的含量（P<0.05）,血清IgA及IgM含量分别较对照组提高了4.59%和4.60%（P>0.05）。③日粮中添加博落回提取物可显著降低断奶仔猪血清中丙二醛（MDA）含量（P<0.05）,同时显著提高总超氧化物歧化酶（T-SOD）活性（P<0.05）。综上所述,在日粮中添加0.1%博落回提取物可降低断奶仔猪腹泻率,并提高机体免疫力及抗氧化能力,且对断奶仔猪生长性能无不良影响。 |

| Abstract: | The experiment was conducted to study the effects of Macleaya cordata extracts on growth performance,serum immune indexes and antioxidant indexes of weaned piglets.120 "Duroc×Landrace×Yorkshire" hybrid pigs with 35 days of age were selected and randomly divided into 2 treatment groups with 5 replicates per group and 12 pigs per replicate,according to similar body weight and the same ratio of gender.The experiment lasted for 30 days with 5 d for preliminary trial.The weaned piglets in control group fed with the basal diet,and that in experimental group fed with basal diet supplemented 0.1% Macleaya cordata extracts.During the experiment,the growth performance was measured (ADG,ADFI and F/G),and at the end of the experiment,two piglets were chosen from each replicate for blood sampling and then the immune and antioxidant indexes were determined.The results showed as follow:①The ADG of weaned piglets supplemented with Macleaya cordata extracts was increased by 3.89% than that of the control group (P>0.05),and the F/G was decreased by 4.32% (P>0.05),meanwhile the diarrhea rate had a significantly decreasing trend(P=0.076).②Compared with the control group,the serum IgG and TNF-α contents of weaned piglets supplemented with Macleaya cordata extracts were significantly increased (P<0.05),the contents of IgA and IgM were increased by 4.59% and 4.60%,respectively (P>0.05).③Adding Macleaya cordata extracts in the diet could significantly reduce the serum MDA content (P<0.05),and significantly increase the T-SOD activity (P<0.05).In conclusion,the addition of 0.1% Macleaya cordata extract in the diet could reduce the diarrhea rate,increase the body immunity and antioxidant capacity,and had no adverse effect on growth performance of weaned piglets. |
