| 31. | · METHODS: The right eyes of 40 1-day-old leghorn chicks were covered with a plastic goggle to induce FDM for 14d after birth, with the left eyes as the control. |
| 方法取40只1d龄来亨雏鸡以半透明眼罩遮盖右眼14d制备FDM动物模型,未遮盖眼为正常眼。 |

| 32. | However, when that antibody is almost gone, the chick becomes susceptible and must be immunized with live vaccine. |
| 当母抗将要消失，鸡只变得敏感时必须使用活疫苗对雏鸡进行免疫。 |

| 34. | The late development stage of chicken embryos( the last week of hatching) and early development stage of chicken growth( the first week after hatching) are the key phases for broiler basic metabolism development, body temperature adjustment and adaptability perfection to environment. |
| 鸡胚发育后期(化期最后1周)雏鸡生长发育早期(雏后第1周)肉鸡基础代谢、温调节和对环境的适应能力完善的关键阶段。 |
|
|
| | |
| 35. | Day-old vaccinations in the hatchery with either live or killed products have been attempted with limited success. |
| 在孵化场使用活苗或灭活苗对1日龄雏鸡进行免疫效果有限。 |
|
|
| | |
| 36. | The chicks show an ataxia not unlike the ataxia of vitamin E deficiency known as encephalomalacia or crazy chick disease. |
| 雏鸡显示共济失调，但与维生素E缺乏的称为小脑软化症或疯狂病（crazy chick disease）不同。 |
|

| 37. | Aflatoxin contamination and toxicity first came to light after the1960 outbreak of so-called“ Turkey X” disease which caused the deaths over100,000 turkey poults in the United Kingdom. |
| 黄曲霉污染及毒性要追溯到1960年英国第一次爆发的火鸡雏鸡的“火鸡X病”。 |

| | |
| 38. | There is some thought that day-old vaccination may at least help prime the immune system to react more readily to IBD vaccines administered later in life. |
| 一些观点认为对1日龄雏鸡进行免疫至少可以启动免疫系统，使免疫系统在以后易于对鸡只进行IBD的免疫产生应答。 |
|
|
| | |
| 39. | INTERVENTIONS:The newly hatched Roman chicks for the experiment were treated with kanamycin monosulfate(200 mg/kg per day) again for 10 consecutive days beginning on 16th day after completion of the initial course. |
| 干预将雏鸡于初次耳中毒后16d开始再次每天肌注卡那霉素(200mg/kg),共10d。 |
|
|
| | |
| 40. | Methods The right eyes of twenty 1-day-old leghorn chicks were closed with a plastic goggle for 14 days to induce form deprivation myopia(FDM),with the left eye as control. Ten FDM eyes' goggles were randomly removed for 7 days as the recovery group. |
| 方法20只1d龄来亨雏鸡以半透明眼罩遮盖右眼14d制备FDM动物模型,随机取10只FDM眼去除遮盖7d作为恢复组,均以对侧未遮盖眼作为对照组。 |
