Study on antioxidant capacity of peanut red coating in mice
The experiment aimed to provide data support for the further development and application of peanut red coating in livestock and poultry breeding by studying the weight gain and antioxidant effects of peanut red coating on mice.The feeding ex-periment was conducted by adding 3%raw peanut red coating(trial group Ⅰ),5%raw peanut red coating(trial group Ⅱ)and 3%cooked peanut red coating(trial group Ⅲ)to the mice diet,and determining the body weight,daily weight gain,and the activities of superoxide dismutase(T-SOD),glutathione peroxidase(GSH-Px)and malondialdehyde(MDA)content in serum and liver tis-sues of mice.The results showed that peanut red coating had no significant effects on body weight and daily weight gain(p＞0.05).The activity of T-SOD and GSH-Px and the content of MDA in serum and liver of mice were significantly affected.As for T-SOD activity,the T-SOD activity in serum of mice in trial groups Ⅰ and Ⅱ was significantly higher than that in control group and trial group Ⅲ(p＜0.05),while the T-SOD activity in serum of mice in trial group Ⅲ was increased by 2.1%compared with the control group,which was not significant(p＞0.05).The T-SOD activity in liver tissues of trial group Ⅱ was significantly higher than that of trial groups Ⅰ,Ⅲ and the control group(p＜0.05),and the T-SOD activity in liver tissues of trial groups Ⅰ and Ⅲ was slightly increased compared with the control group,but did not reach a significant level(p＞0.05).As for the GSH-Px activity,the serum GSH-Px activity in trial groups Ⅰ and Ⅱ was significantly higher than that in the control group and trial group Ⅲ(p＜0.05),while the serum GSH-Px activity in trial group Ⅲ was increased by 6.89%compared with the control group(p＞0.05).The activity of GSH-Px in liver tissues of trial group Ⅱ was significantly higher than that of the control group and tri-al group Ⅰ(p＜0.05),but there was no significant difference compared with trial group Ⅲ(p＞0.05),and the activity of GSH-Px in liver tissues of trial group Ⅲ was significantly higher than that of control group(p＜0.05).In terms of MDA content,the MDA content in serum and liver tissue of mice in three trial groups was significantly lower than that in the control group(p＜0.05).This showed that peanut red coating had better antioxidant effect on mice,and the antioxidant effect of raw peanut red coating was better than that of cooked peanut red coating.The 5%raw peanut red(trial group Ⅱ)had the best antioxidant effect.It is advisable to add 5%of raw peanut red coating in livestock and poultry farming.
