The purpose of the experiment was to study the effects of Chinese herbal compound in high concentrate diet on growth performance, apparent digestibility of nutrients, serum biochemical indexes, immunity, anti-inflammatory, and antioxidant functions of sheep. Thirty 3-month-old male lambs with the body weight of (20.81±1.27) kg were randomly divided into three groups with ten replicates in each group and one lamb in each replicate. The ratio of concentrate to crude in basal diet was 75:25, and the addition amount of Chinese medicine compound in control group, Z1 group, and Z3 group was 0, 10, 30 g/d, respectively. The pre-test period was 15 days, and the formal test period was 50 days. The results showed that compared with the control group, adding 30 g/d Chinese herbal compound could increase the final body weight and average daily gain of sheep (P<0.05), decrease the feed-weight ratio (P<0.05), increase the apparent digestibility of crude protein (P<0.05), decrease the content of serum urea nitrogen (P<0.05), decrease the content of serum triglyceride (P<0.05), increase the contentrations of low density lipoprotein cholesterol and high density lipoprotein cholesterol (P<0.05), increase the total antioxidant capacity and the activities of catalase, glutathione peroxidase and total superoxide dismutase in serum (P<0.05), decrease the content of malondialdehyde in serum (P<0.05), increase the activities of acid phosphatase and lysozyme in serum and the contentrations of immunoglobulin and interferon-γ in serum (P<0.05), and decrease the contentrations of nitric oxide, lipopolysaccharide, interleukin-1β, interleukin-6 and tumor necrosis factor-α in serum (P<0.05). The study indicates that adding 30 g/d of Chinese medicine compound in high concentrate diet can improve the antioxidant capacity and immune function of sheep, reduce the level of serum pro-inflammatory factors, relieve the inflammation of the body, improve the daily gain and apparent digestibility of nutrients of sheep, and has a positive impact on keeping the health of sheep.
