Abstract:

To study the effects of bamboo vinegar powder on the antioxidant and immune indexes of blood and colostrums in late-pregnant Hu ewe, ten healthy late-pregnant primiparous Hu ewes at about 120 days were chosen and randomly divided into 2 groups with 5 ewes per group. The basic diet and the basic diet added with 2% of bamboo vinegar powder were fed to the ewes in control and experimental groups respectively, and the trial period were 3 weeks including 1 week of preparatory feeding and 2 weeks of formal trial period. The blood samples were collected and detected for the biochemical, immune and antioxidant indexes after finishing experiment. The colostrum was collected within a week after parturition and measured for immune and antioxidant indexes also. The results showed that:①Compared with the ewes in control group, the total protein (TP) content and glutamic-pyruvic transaminase (GPT) activity of blood in experimental ewes were significantly increased (P<0.05), while the glutamic oxalacetic transaminase (GOT)/GPT and platelet counts were significantly decreased (P<0.05), and the red blood cell counts and the hemoglobin concentration were increased with no significant difference (P>0.05);②Compared with the control group, the serum interleukin-6(IL-6) and immune globulin A(IgA) contents of ewes in experimental group were increased significantly (P<0.05), the total antioxidant capacity (T-AOC), immune globulin G(IgG) and immune globulin M(IgM) contents were extremely significantly increased (P<0.01), the tumour necrosis factor-α(TNF-α) content was decreased with no significant difference (P>0.05);③Bamboo vinegar powder significantly decreased the TNF-α content (P<0.05), increased the superoxide dismutase(SOD) activity (P<0.05) of colostrum, but the immunoglobulin content had no significant changes(P>0.05). In conclusion, diet supplemented with bamboo vinegar powder could improve the healthy and enhance the antioxidant and immune performance of late-pregnant Hu ewe.
