Effects of Chinese medicine compound on growth performance,serum biochemical indexes,immunity,and antioxidant function of sheep
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,Zl 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-y 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.
