摘要: 旨在探究慢性氧化应激对断奶仔猪器官组织微量元素的影响。试验选用12头断奶杜长大三元杂交仔猪,随机平均分为对照组和氧化应激组,每组6 头,对照组饲喂基础饲粮,氧化应激组在基础饲粮中额外添加10 g·kg-1 体重剂量的 D-半乳糖。试验检测了断奶仔猪器官组织中微量元素含量及其表观消化率。试验结果表明:氧化应激组断奶仔猪肝中Mn的含量、肾中Fe和Mn含量、空肠中Zn含量和结肠中Fe、Cu和Mn含量均显著低于对照组(P<0.05);而氧化应激组断奶仔猪肝中Fe和Zn含量、空肠中Fe和Cu含量、回肠中Fe和Cu含量均显著高于对照组(P<0.05)。与对照组相比,氧化应激组断奶仔猪Cu、Fe和Mn的表观消化率显著降低(P<0.05)。综上所述,D-半乳糖诱导的慢性氧化应激模型可改变断奶仔猪各器官组织微量元素含量,降低微量元素在仔猪体内的表观消化率。

Abstract: The purpose of this study was to investigate the effects of chronic oxidative stress on trace elements in organs and tissues of weaned piglets. Twelve weaned Duroc×Landrace×Yorkshire crossbred piglets were randomly divided into control group and oxidative stress group, with 6 piglets in each group. The control group was fed a basal diet, and the oxidative stress group was fed the basal diet supplemented with 10 g·kg-1 body weight dose of D-galactose.The experiment detected the trace elements in the organ tissues of weaned piglets and the apparent digestibility of the trace elements. The results showed that the contents of Mn in liver, Fe and Mn in kidney, Zn in jejunum, Fe, Cu and Mn in colon of weaned piglets in oxidative stress group were significantly lower than those in the control group (P<0.05). The contents of Fe and Zn in liver, Fe and Cu in jejunum, Fe and Cu in ileum of weaned piglets in oxidative stress group were significantly higher than those in the control group (P<0.05). Compared with the control group, the apparent digestibility of Cu, Fe and Mn were significantly decreased in oxidative stress group (P<0.05).In summary, the chronic oxidative stress model induced by D-galactose can change the content of trace elements in various organs and tissues of weaned piglets and reduce the metabolic efficiency of apparent digestibility in piglets.
