Abstract

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.

Key words: chronic oxidative stress, weaned piglets, race elements
