摘　　要：本试验旨在研究不同添加水平的巴西人参叶对灵山鸡生长及胃肠道发育的影响。选用健康、体重接近的7日龄灵山鸡240只,随机分为4个处理组,包括1个对照组(基础饲粮组)和3个试验组(基础日粮中分别添加1%、2%、3%的巴西人参叶),每组6个重复,每个重复10只灵山鸡,试验期35d。结果表明:1)各处理组间灵山鸡末重差异不显著(P>0.05);添加人参叶极显著提高胸宽(P<0.05),但各添加组间差异不显著(P>0.05),径长等其它体尺指标不受饲粮的影响(P>0.05);2)添加不同水平的巴西人参叶对灵山鸡胃器官指数及肠道系数均无显著影响(P>0.05);3)趋势分析表明,胸宽随着巴西人参叶添加量的增加呈现二次曲线,根据拟合方程求得巴西人参叶的适宜添加水平为1.32%。综上所述,饲粮中添加适量的巴西人参叶对2~6周龄灵山鸡的生长发育有一定的积极影响,其适宜添加水平为1.32%。This experiment was conducted to investigate the effects of different levels of pfaffia paniculata leaves on the growth and gastrointestinal tract development of Lingshan chickens.A total of 240 seven-day old healthy Lingshan chickens with similar body weight were selected and randomly divided into four treatment groups with six replicates of 10 birds for 35 days.The treatments were a basal diet supplemented with 0,1%,2%,and 3%pfaffia paniculata leaves,respectively.The results showed as follows:1)The final weight of Lingshan chickens did not differ among treatments(P>0.05).The chest width index of all supplemental groups was significantly higher than that of the control group(P<0.05),but there was no significant difference among the supplemental groups(P>0.05).Other body size values such as diameter length were not affected by the dietary supplementation of pfaffia paniculata leaves(P>0.05).2)The pfaffia paniculata leaves supplementation had no significant effects on the organ indices and stomach,duodenum and ileum correction coefficients of Lingshan chickens(P>0.05).3)Based on the regression analysis,the chest depth showed the quadratic curve as the increase of the supplemental level of pfaffia paniculata leaves.According to the fitting equation,the appropriate supplemental levels of pfaffia paniculata leaves was 1.32%.In conclusion,the dietary appropriate supplementation of pfaffia paniculata leaves had the positive effects on the growth and development of Lingshan chickens at 2 to 6 weeks of age.The recommendation level are1.32%.
