| Summary: | The present experiment was conducted to study the effects of chitosan (CHI) on immune and antioxidative function in beef cattle. A total of 24 fattening Simmental cattle with similar body weight and age were divided randomly into three dietary groups, and the three diets contained 0, 500, and 1000 mg/kg CHI, respectively. The feeding trial lasted for 84 days. It was found that: (1) the addition of CHI in diets improved (P < 0.05) the levels of IgA and interleukin-1, and decreased (P < 0.1) the levels of soluble cluster of differentiation 4 receptor in serum at middle stage except that IgA remained unchanged in 1000 mg/kg CHI group. The levels of IgM and IgA tended to be increased (P < 0.1) by dietary CHI at later stage of the experiment; (2) the addition of 500 mg/kg CHI in diets increased (P < 0.1) total superoxide dismutase activity and decreased (P < 0.05) malondialdehyde content in serum at early and later stages, respectively. In conclusion, these results indicated that addition of 500 mg/kg CHI affected humoral and cellular immune responses, and improved the antioxidative function of beef cattle. |
