| 摘要: |
| 将132只455日龄尼克红蛋鸡随机分成A,B,C,D 4组(n= 33),A组喂基础日粮,B,C,D 3组分别在基础日粮中添加1%, 2%, 4%的中药“增蛋宝”。结果表明:B,C,D 3组的产蛋率和饲料报酬分别比A组提高14. 48%, 16. 89%, 17. 15%和19. 27%, 20. 48%,20. 53%,以B组的经济效益最为明显;试验组与对照组相比,除T淋巴细胞E花环百分率、血清总蛋白(TP)、血清球蛋白(G)、血清白蛋白(A)显著增加(P<0. 05或P>0. 01)外,其余8项血液指标均无显著变化(P>0. 05),临床观察和病理学剖检,各试组无任何不良反应。 |

| Abstract: |
| One hundred and thirty two hens of 455 days old were randomly divided
into four groups (A, B, C and D), with thirty three in each grorp.Hens in group A
were given ration only,while B, C and D were given ration plus 1%, 2%, 4% of Chinese
midicine Zengdanbao, respectively. The results showed that the rate of laying and feed
conversion in group B, C and D increased by 14. 48%, 16. 89%, 17. 15% and 19. 27%,
20. 48%, 20. 53% than group A, respectively.Comparing test group with the control's,
the percent of T cell E rossette froming cell, serum total protein. globulin, albumin was
significantly increased (P<0. 05 or P>0. 01),while the other 8 items of blood had no
significant difference (P>0. 05).Results from clinical observation and pathological anotomy indicated that there was no any harmful response in all groups. |
