Effects of Qi-Zha Oral Solution Residues and Fermented Qi-Zha Oral Solution Residues on Plasma Biochemical Parameters and Antioxidant Ability of Weaned Piglets
摘要
Abstract
The present study was conducted to determine the effects of Qi-Zha oral solution residues (QOR) and their fermented product on plasma biochemical parameters and antioxidant ability of weaned piglets, to explore the feasibility of dietary supplementation with herbal residues.A total of 120 piglets weaned at 21 days of age were randomly assigned to one of four groups with five replicates per group and six piglets per replicate, representing blank control group (without adding antibiotics and zinc oxide), QOR group (supplemented with 5 kg/t QOR), fermented QOR group (supplemented with 5 kg/t fermented QOR) and positive control group (supplemented with 0.04 kg/t virginiamycin+0.2 kg/t colimycin+3 000 mg/kg zinc oxide).The experiment lasted for 28 days, and at the 7th and 28th day of the experiment, the blood samples were collected, respectively, for determining biochemical parameters and antioxidant indices.The results showed that, at the 7th day of the experiment, dietary supplemented with fermented QOR significantly increased the plasma contents of total protein (TP) and globulin (GLB) (P<0.05), and significantly decreased the ratio of albumin to GLB (ABL/GLB) (P<0.05) compared with the two control groups, as well as significantly increased plasma triglyceride content compared with the positive control group (P<0.05), while significantly decreased the plasma aspartic transaminase activity compared with the blank control group (P<0.05) and the plasma alkaline phosphatase activity compared with the QOR group and two control groups (P<0.05).At the 28th day of the experiment, dietary supplemented with QOR significantly increased the plasma contents of TP and total cholesterol (P<0.05), while significantly decreased ALB/GLB (P<0.05) compared with the positive control group, dietary supplemented with fermented QOR significantly decreased plasma high-density lipoprotein cholesterol content and superoxide dismutase (SOD) activity compared with the QOR group (P<0.05), and also significantly decreased the plasma glutathion peroxidase (GSH-Px) activity compared with the QOR group and blank control group (P<0.05).At the 28th day of the experiment, the plasma catalase activity in QOR group, contents of TP and GLB and GSH-Px activity in the fermented QOR group, and the plasma contents of TP, GLB and ALB in two control groups were significantly decreased (P<0.05), while the plasma SOD activity in the QOR group, ALB/GLB in the fermented QOR group and positive control group were significantly increased (P<0.05) compared with the 7th day of the experiment.Collectively, these findings suggest that dietary supplementated with the QOR can improve the immunity of weaned piglets, and dietary supplementated with the QOR or fermented QOR do not adversely affect the liver.Therefore, they can be used as feed additive in swine production.关键词
