摘　　要：试验旨在研究不同来源的植物精油对仔猪生长性能的影响,为植物精油在仔猪饲养和饲料生产中的应用提供科学依据。试验1选取384头体重(7.90±0.46)kg的PIC断奶仔猪,按体重随机分为4个处理组,每个处理组4个重复,每个重复24头仔猪。对照组饲喂不含抗生素和精油的商品饲粮,试验组在对照组饲粮中分别添加R精油、A精油和B精油,试验周期为32 d。试验2选取320头保育阶段、体重(10.92±0.53)kg的PIC仔猪,按体重随机分为4个处理组,每个处理组4个重复,每个重复20头仔猪。对照组饲喂不含抗生素和精油的商品饲粮,试验组在对照组饲粮中分别添加R精油、A精油和B精油,试验周期为23 d。试验1结果显示:与对照组相比,R精油和B精油能显著降低断奶仔猪的料重比(P<0.05),其中R精油的料重比最低。此外,只有R精油能显著降低断奶仔猪的腹泻率(P<0.01)。试验2结果显示:R精油组保育仔猪的料重比显著低于对照组和其他试验组(P<0.05),试验期间各处理组保育仔猪的腹泻率差异均不显著(P>0.05)。此外,几种精油对仔猪的毛况和肤色均没有显著影响(P>0.05)。综上所述,饲粮添加R精油能显著改善断奶和保育仔猪的生产性能,且效果优于A精油和B精油产品。This study was to investigate the effects of plant essential oils from different sources on the growth performance of piglets,and to provide scientific basis for the application of plant essential oils in piglet feeding and feed production.In experiment 1,384 PIC weaned piglets with body weight(7.90±0.46)kg were randomly divided into 4 groups with 4 replicates of 24 piglets each.The control group was fed commercial diet without antibiotic and plant essential oil,and the experimental group was fed essential oil R,essential oil A and essential oil B,respectively.The feeding trial lasted 32 days.In Experiment 2,320 PIC nursery piglets with body weight(10.92±0.53)kg were randomly divided into 4 treatment groups with 4 replicates of 20 piglets each.The control group was fed commercial diet without antibiotic and plant essential oil,and the experimental group was fed a certain amount of essential oil R,essential oil A and essential oil B,respectively.The feeding trial lasted 23 days.The results of experiment 1 showed that compared with the control group,essential oils R and B could significantly reduce the F/G of weaned piglets(P<0.05),and the F/G of essential oil R was the lowest.In addition,only essential oil R can significantly reduce the diarrhea rate of weaned piglets(P<0.01).The results of experiment 2 showed that the F/G of nursery piglets with essential oil R was significantly lower than that of the control group and other experimental groups(P<0.05).During the experiment,there was no significant difference in diarrhea rate among all treatment groups(P>0.05).In addition,several essential oils had no significant effect on the hair condition and skin color of piglets(P>0.05).In conclusion,adding R essential oil to the diet can significantly improve the production performance of weaned and nursery piglets,and the effect is better than that of A essential oil products and B essential oil products.
