试验旨在研究高精料饲粮中添加中药复方对绵羊生长性能、养分表观消化率、血清生化指标、免疫、抗炎和抗氧化功能的影响.选取30只体重(20.81±1.27)kg的3月龄杜寒杂交公羔,随机分为3组,每组10个重复,每个重复1只羊.基础饲粮精粗比为75∶25,对照组、Z1组和Z3组的中药复方添加量分别为0、10、30 g/d.预试期15 d,正式试验期50 d.结果显示,与对照组相比,添加30g/d中药复方可以提高绵羊的末重和平均日增重(P＜0.05),降低料重比(P＜0.05),提高粗蛋白表观消化率(P＜0.05),降低血清尿素氮的含量(P＜0.05),降低血清中甘油三酯含量(P＜0.05),增加低密度脂蛋白胆固醇和高密度脂蛋白胆固醇含量(P＜0.05),提高血清中总抗氧化能力以及过氧化氢酶、谷胱甘肽过氧化物酶和总超氧化物歧化酶的活性(P＜0.05),降低血清中丙二醛含量(P＜0.05),提高血清中酸性磷酸酶、溶菌酶活性以及免疫球蛋白、干扰素-γ含量(P＜0.05),降低血清中一氧化氮、脂多糖、白细胞介素-1β、白细胞介素-6和肿瘤坏死因子-α含量(P＜0.05).研究表明,在高精料饲粮中添加30 g/d的中药复方可以提高绵羊的抗氧化能力和免疫功能,降低血清促炎因子水平,缓解机体炎症,提高绵羊的日增重和养分表观消化率,对保持绵羊机体健康具有积极影响.
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.
