| 摘 要： | 旨在验证复合植物精油（百里香酚7.3%,牛至油10.0%）改善断奶仔猪生长性能的功效。选用160头体重相近、体况良好、28日龄断奶的杜×长×大三元杂交仔猪,随机分成4组,分别为对照组和试验1、2、3组,每组4个重复,每个重复10头猪。对照组饲喂玉米—豆粕型基础日粮,试验1、2、3组在基础日粮中分别添加80、120、150 mg/kg复合植物精油。试验期间观察并记录仔猪生长及健康状况,试验结束时,采用统计学方法比较各组仔猪的生长性能指标（末体重、平均日增重、平均日采食量、料重比）、健康指标（腹泻率、死淘率）以及肠道黏膜通透性指标（D-乳酸含量、二胺氧化酶活性）。结果表明,与对照组相比,试验2、3组仔猪的末体重、平均日增重、平均日采食量均显著提高（P〈0.05）,料重比则显著降低（P〈0.05）;3个试验组仔猪的腹泻率及死淘率均显著低于对照组（P〈0.05）;与对照组相比,3个试验组仔猪血浆中的D-乳酸含量和二胺氧化酶活性分别极显著（P〈0.01）和显著降低（P〈0.05）。综合考虑促生长效果及饲养成本,仔猪基础日粮中复合植物精油的推荐添加量为120 mg/kg。

Effect of Dietary Supplementation of Compound Plant Essential Oils on Growth Performance and Health of Weaning Piglets |
| |
| Abstract: | This study was conducted to investigate the effect of dietary supplementation of compound plant essential oils（thymol7.3%, Origanum oil 10.0%） on growth performance and health of weaning piglets. A total of 160 healthy early-weaned piglets（Duroc×Landrace×Yorkshire） of 28-day-old with similar body weight were randomly allotted to 4 groups with 4 replicates per group and 10 piglets per replicate. Pigs in the 4 groups were fed a corn-soybean meal diet supplemented with compound plant essential oils 0 mg/kg（control group）, 80 mg/kg（group 1）, 120 mg/kg（group 2） and 150 mg/kg（group 3）, respectively. Feed intake, body weight and healthy status of the piglets were observed and recorded during the experimental period. The growth performance indicators（final boy weight, average daily weight gain, average daily feed intake, feed/gain ratio）, healthy indicators（diarrhea rate, death and culling rate）, and the intestinal mucosal permeability indicators（D-lactate, diamine oxidase） of different groups were calculated and statistically compared. The results showed that the final boy weight, average daily weight gain, average daily feed intake of group 2 and group 3 were significantly elevated compared to the control group（P〈0.05）, while the feed/gain ratio was significantly decreased（P〈0.05）; the diarrhea rate as well as death and culling rate of the 3 experimental groups were significantly reduced compared to the control group（P〈0.05）; the plasma level of D-lactate and activity of diamine oxidase of the 3 experimental groups were extremely significantly or significantly decreased compared to the control group（P〈0.01 or P〈0.05）, respectively. Taking the growth promoting effect and feeding cost together into consideration, the recommended supplementing amount of compound plant essential oils in basal diet of weaning piglets was 120 mg/kg. |
