Effects of dietary oregano extract on growth performance,antioxidant capacity and serum biochemical indices of piglets during conservation period
The purpose of this study was to analyze the effects of dietary supplementation of oregano extract on growth performance,antioxidant capacity and serum biochemical indices of piglets during conservation period.A total of 120 healthy piglets with average body weight of(7.65±0.11)kg and age of 30 days were selected and divided into 4 groups according to the dose difference of dietary supplementation of Oregano extract(3 replicates per group).Feeding the basic diet+100 g/t oregano extract was set as the control group,feeding the basic diet+100 g/t oregano extract was set as the trial group I,feeding the basic diet+200 g/t oregano extract was set as the trial group Ⅱ,feeding the basic diet+300 g/t oregano extract was set as the trial group Ⅲ.The trial period was 40 days.After the end of the experiment,the relevant indexes of each treatment were compared and analyzed.The results showed as follows:(1)growth performance:there were no significant differences in initial weight and daily average feed intake among all groups(P＞0.05).The final weight and daily average gain of test group Ⅱ were significantly higher than those of the other three groups(P＜0.05),and the ratio of feed to gain was significantly lower than that of the other three groups(P＜0.05).(2)Antioxidant capacity:Compared with the control group,superoxide dismutase and glutathione peroxidase indexes in trial groups I,Ⅱ and Ⅲ were significantly increased,and malondialdehyde was significantly decreased;(3)Serum biochemical indices:the contents of total cholesterol and triglyceride in test group Ⅱ were significantly lower than those in the other three groups(P＜0.05),and globulin and albumin were significantly higher than those in the other three groups(P＜0.05).In conclusion,the supplementation of oregano extract in the basic diet of piglets can enhance growth performance,increase antioxidant capacity and improve serum biochemical indexes,and the improvement effect of the above indexes is most obvious at the supplemental level of 200 g/t.
