本研究的目的是评价在断奶仔猪日粮中添加精油对仔猪生产性能、营养物质利用、免疫反应和肠道健康的影响。试验选用96头断奶仔猪（8.37±1.58 kg），随机分为3组。处理由未补充的基础饮食（阴性对照，NC）或补充有0.01%的含有18%百里酚和肉桂醛（EOD）的精油产品的类似饮食以及补充有0.19%的抗生素混合物的饮食组成，所述抗生素混合物提供150 ppm金霉素、80 ppm硫酸粘杆菌素和50 ppm吉他霉素（阳性对照，PC）。每种处理提供给8个猪圈，每个猪圈4头猪。在整个35 d的试验中，与NC相比，PC和EOD饲喂的猪的ADG和粪便评分得到改善（p<0.05）。与NC相比，PC组和EOD组的干物质和粗蛋白消化率以及淋巴细胞增殖率显著提高（p<0.05）。与饲喂NC饮食的猪相比，饲喂PC饮食的猪血浆中IGF-I水平显著增加（p<0.05）。与NC组相比，EOD组血浆中IL-6水平显著降低（p <0.05），TNF-α水平显著升高（p<0.05）。与饲喂NC的猪相比，饲喂EOD的猪血浆总抗氧化能力水平增加（p<0.05）。饲喂PC和EOD日粮的猪空肠中绒毛高度与隐窝深度的比率大于NC（p<0.05）。E.与对照组相比，饲喂PC和EOD日粮的猪盲肠、结肠和直肠中的大肠杆菌数量显著降低（p<0.05）。在结肠中，乳酸杆菌与E.与NC组相比，EOD组仔猪大肠杆菌感染率显著升高（p<0.05）。与对照组相比，饲喂PC和EOD日粮的猪直肠需氧菌总数降低（p<0.05）。总的来说，这些结果表明，精油的混合物可以作为替代传统抗生素在断奶仔猪日粮中使用的候选人。
The objective of this study was to evaluate the effects of adding essential oils to the diet of weaned pigs on performance, nutrient utilization, immune response and intestinal health. A total of 96 weaning pigs (8.37±1.58 kg) were allotted to one of three dietary treatments. The treatments consisted of an unsupplemented basal diet (negative control, NC) or similar diets supplemented with 0.01% of an essential oil product which contained 18% thymol and cinnamaldehyde (EOD) as well as a diet supplemented with 0.19% of an antibiotic mixture which provided 150 ppm chlortetracycline, 80 ppm colistin sulfate and 50 ppm kitasamycin (positive control, PC). Each treatment was provided to eight pens of pigs with four pigs per pen. Over the entire 35 d experiment, ADG and fecal score were improved (p<0.05) for pigs fed the PC and EOD compared with the NC. Dry matter and crude protein digestibility as well as lymphocyte proliferation for pigs fed the PC and EOD diets were increased significantly compared with NC (p<0.05). IGF-I levels in plasma were significantly increased (p<0.05) in pigs fed the PC diet compared with pigs fed the NC diet. Interleukin-6 concentration was lower (p<0.05) and the tumor necrosis factor-α level was higher (p<0.05) in the plasma of pigs fed the EOD diet than the NC diet. Plasma total antioxidant capacity level increased (p<0.05) in pigs fed the EOD diet compared with pigs fed the NC. Villus height to crypt depth ratio in the jejunum was greater (p<0.05) in pigs fed the PC and EOD diets than the NC. The numbers of E. coli in the cecum, colon and rectum were reduced (p<0.05) in pigs fed the PC and EOD diets compared with the control. In the colon, the ratio of Lactobacilli to E. coli was increased (p<0.05) in pigs fed the EOD diet compared with NC diet. Total aerobe numbers in the rectum were decreased (p<0.05) in pigs fed the PC and EOD diets compared with the control. Collectively, these results indicate that blends of essential oils could be a candidate for use as an alternative to traditional antibiotics in weaning pig diets.
