| 摘 要： | 以高邮鸭为试验对象,研究中草药制剂添加量对蛋鸭生产性能与肠道健康状况的影响.结果表明:试验鸭采食量仅0.08%组低于对照组;产蛋量仅0.10%组和0.20%组低于对照组,各组中0.14%组产蛋量最高,达到632.85g;平均产蛋率仅0.10%组低于对照组;料蛋比仅0.10%组和0.20%组比对照组高,各组中0.14%组料蛋比最佳(2.86∶1).蛋黄颜色0.18%组显著低于0.08%组和0.12%组(p<0.05),并低于对照组;而其他组都等于或优于对照组.中草药制剂添加量添加后对十二指肠形态指标的影响各异,仅0.12%组相对对照组表现出绒毛高度更高,绒毛宽度较小及绒毛高度与隐窝深度比值最大的肠道形态.大肠杆菌数除0.08%,0.10%和0.20%组高于对照组外,其他组均低于对照组,其中以0.12%组最佳,而0.08%组显著高于0.12%组(p<0.05);沙门氏菌数除0.08%组高于对照组外,其他各组均低于对照组.综合分析,添加0.12%的中草药制剂能获得最好的生产性能、肠道形态和最低的肠道有害菌含量.

| Abstract: | An experiment was conducted to study the effects of different contents of herbal addatives in diets on growth performance and small intestine morphology of Gaoyou ducks.A total of 400 280-day-old Gaoyou ducks were randomly assigned to 8 groups with 5 replicates per group and 10 ducks per replicate.The control group was fed with basal diet,and the other groups were fed with basal diet enriched with 0.08%,0.10%,0.12%,0.14%,0.16%,0.18% and 0.20% of the herbal additive,respectively.The experiment lasted 35 days.Compared with the control group,all the experiment groups had higher feed intake except the 0.08% group,which had lower feed intake.The two groups with 0.10% and 0.20% herbal additives had lower mass egg weight than the control group,while the others had higher mass egg weight,the highest(632.85 grams) being obtained in the 0.14% group.Only the 0.10% group had lower average laying rate than the control group.The mass egg weight of the groups fed with the herbal additive was higher than thecontrol group,except the 0.10% and 0.20% groups.The mass egg weight of the 0.14% group was higher than others,being 632.85 grams.The feed/egg weight ratio of the 0.10% and 0.20% groups was higher than that of the control group,while the other groups’ was lower than control group.The 0.14% group gave the best feed/egg weight ratio of 2.86∶1.There were no differences between groups fed with the herbal additive and the control group in egg weight,albumen height,Hu and yolk weight(p>0.05).There was a significant difference in egg yolk color between the 0.18% group and the 0.08% and 0.12% groups(p<0.05).Only the 0.18% group egg had lower yolk color than the control group.Compared with the control group,the groups fed with the herbal additive had no difference in small intestine morphology(p>0.05).Only the 0.12% group gained higher villus height value,deeper crypt depth,more slender villus width,and better V/C value more better.The number of coliform of 0.08%,0.10% and 0.20% groups was greater than the control group.There was a significant difference between the 0.08% and 0.12% groups(p<0.05) in the number of E.coil.The number of salmonella of the experiment groups was higher than that of the control group.In short,the diet with 0.12% herbal additive could be gain the best growth laying performance and the lower number of coliform and salmonella in ileum of Gaoyou ducks. |
