Abstract:

The experiment was conducted to study the effect of chicken spleen transfer factor (TF)on intestine antioxidant capacity and the mechanism on production and immunity ability of chicken. One hundred chickens of 1-day-old were selected and were divided into 5 groups. Four TF groups including 20 chickens each received TF treatment as follows: 0.05 mL (Minimum dose group), 0.10 mL (Low dose group), 0.25 mL (Medium dose group), 1 mL (High dose group) per chicken TF were given for one week by drinking water every day from 5-days-old to 12-days-old, respectively, and then fed without TF to 19-days-old. Group 5th was normal control group. Fifty chickens were killed at 12-days-old and 19-days-old, respectively. The chickens were weighted, and the antioxidant capacity of the duodenum, jejunum, ileum and rectum were measured. The results showed that one week' treatment of TF showed an increased tendency of body weight, yet the effect was not obvious. However, the high TF dose group significantly increased the activity of SOD (17.07%-31.54%), CAT (16.98%-25.77%), GSH-PX (13.99%-23.59%) and T-AOC (16.48%-43.16%) of duodenum, jejunum, ileum and rectum, but significantly reduced the activity of MDA (P<0.05) in intestine. The activities of T-AOC, SOD in the intestinal segments, CAT (except for ileum) and GSH-PX (except for duodenum) were significantly increased in the middle dose groups (P<0.05), but the content of MDA was decreased significantly in the low and middle dose groups (P<0.05). At 19 days old, the changes of T-AOC, CAT, GSH-PX, SOD and MDA in each intestinal group were decreased compared with 12 days old, but there was still significant in individual intestinal segment (P<0.05). The results indicate that the TF, as a new feed additive, has a significant role in improving anti-oxidative stress ability.
