Abstract

INTRODUCTION

This trial was conducted to compare the effect of diets supplemented with plant essential oil (PEO) and coated plant essential oil (CEO) on growth performance, immunity, antioxidant activity, and fecal microbiota of weaned piglets.

METHODS

A total of 360 21-day-old weaned piglets were randomly allocated into three groups, namely, CON, PEO, and CEO (basal diets supplemented with 0, 500 mg/kg PEO, and 500 mg/kg CEO, respectively) for a 4-week feeding trial.

RESULTS AND DISCUSSION

The results showed that dietary supplementation with CEO improved the average final weight and average daily gain, decreased the diarrhea rate, increased antioxidant enzyme activities, enhanced immunoglobulin concentrations, and decreased concentrations of pro-inflammatory cytokines in the serum of weaned piglets ( < 0.05). In addition, CEO addition increased the fecal concentrations of propionic acid and isovaleric acid of piglets ( < 0.05). Spearman correlation analysis showed that fecal microorganisms at the genus level were closely correlated with the volatile fatty acid concentrations. The present study indicated that PEO and CEO could improve growth performance, enhance immunity, and increase antioxidant capacity by modulating the microbial flora in weaned piglets. Moreover, CEO addition seemed to offer more positive results than of PEO addition.

摘要

引言

本试验旨在比较添加植物精油（PEO）和包膜植物精油（CEO）的日粮对断奶仔猪生长性能、免疫力、抗氧化活性和粪便微生物群的影响。

方法

将360头21日龄断奶仔猪随机分为三组，即对照组（CON）、PEO组和CEO组（基础日粮分别添加0、500mg/kg PEO和500mg/kg CEO），进行为期4周的饲养试验。

结果与讨论

结果表明，日粮中添加CEO可提高断奶仔猪的平均末重和平均日增重，降低腹泻率，提高抗氧化酶活性，增强免疫球蛋白浓度，并降低血清中促炎细胞因子的浓度（P<0.05）。此外，添加CEO可提高仔猪粪便中丙酸和异戊酸的浓度（P<0.05）。Spearman相关性分析表明，属水平的粪便微生物与挥发性脂肪酸浓度密切相关。本研究表明，PEO和CEO可通过调节断奶仔猪的微生物菌群来提高生长性能、增强免疫力和提高抗氧化能力。此外，添加CEO似乎比添加PEO能带来更积极的效果。
