Effects of sodium butyrate on growth performance,muscle amino acid composition,and anti-inflammatory performance in weaned piglets
文章系统评估了不同剂量丁酸钠对断奶仔猪生长性能、肌肉氨基酸组成及抗炎性能的影响.试验选取200 头 28 日龄断奶仔猪[(8.50±0.50)kg],随机分为 4 组,每组 5 个重复,每个重复 10 头猪.对照组饲喂基础日粮,试验组分别添加 250、500 和 1000 mg/kg 丁酸钠,试验为期 42 d.结果表明,与对照组相比,500 和 1000 mg/kg 丁酸钠添加组的末重分别显著提高 4.2％和 7.5％(P<0.05),平均日增重分别显著提高 9.8％和 13.6％(P<0.05),料重比分别显著降低 6.7％和 9.2％(P<0.05).血清炎症指标显示,500 和 1000 mg/kg 添加组肿瘤坏死因子-α(TNF-α)水平分别显著降低 23.0％和 27.1％(P<0.05),白细胞介素-1β(IL-1β)含量分别显著下降 20.1％和25.5％(P<0.05),同时白细胞介素-10(IL-10)水平分别显著提高 33.3％和 35.9％(P<0.05).肌肉氨基酸组成方面,500 和 1000 mg/kg 添加组赖氨酸含量分别显著提高 8.3％和 13.5％(P<0.05),谷氨酸含量分别显著增加 9.7％和 14.3％(P<0.05).综上所述,日粮中添加 500～1000 mg/kg 丁酸钠可有效改善断奶仔猪生长性能,缓解炎症反应并优化肌肉品质,其中 1000 mg/kg 添加剂量的综合效益最佳.
This study systematically evaluated the effects of sodium butyrate at different doses on the growth performance,muscle amino acid composition,and anti-inflammatory properties of weaned piglets.A total of 200 weaned piglets aged 28 days(8.50±0.50 kg)were randomly divided into 4 groups,each with 5 replicates of 10 piglets.The control group was fed a basal diet,while the experimental groups received diets supplemented with 250,500,and 1000 mg/kg sodium butyrate,respectively.The trial lasted for 42 days.The results showed that compared with the control group,the final body weights in the 500 mg/kg and 1000 mg/kg sodium butyrate groups significantly increased by 4.2％and 7.5％(P<0.05),respectively;the average daily gains significantly improved by 9.8％and 13.6％(P<0.05),respectively;and the feed-to-gain ratios significantly decreased by 6.7％and 9.2％(P<0.05),respectively.Serum inflammation indicators showed that the TNF-α levels in the 500 mg/kg and 1000 mg/kg groups significantly decreased by 23.0％and 27.1％(P<0.05),respectively;the IL-1β levels significantly declined by 20.1％and 25.5％(P<0.05),respectively;and the IL-10 levels significantly increased by 33.3％and 35.9％(P<0.05),respectively.Regarding muscle amino acid composition,the lysine content in the 500 mg/kg and 1000 mg/kg groups significantly increased by 8.3％and 13.5％(P<0.05),respectively;while the glutamate content significantly rose by 9.7％and 14.3％(P<0.05),respectively.In summary,dietary supplementation with 500-1000 mg/kg sodium butyrate can effectively improve the growth performance of weaned piglets,alleviate inflammatory responses,and optimize muscle quality,with the 1000 mg/kg dose providing the most comprehensive benefits.
