Work with your partner and try to fill in the following blanks.Chicken eggs require _ days to hatch. During the first three days, we can see the tissue development starts, the _ forms

3、and begins to beat from day 4 to day 6. Some joints, such as knees and elbows start forming and the wings can now bend. On the 8th day, a ridge of glands is formed where the feathers will appear on the tail and thighs. The head turns towards the _ end of the egg on the 14th day, the air cell becomes

4、 much smaller, and the yolk sac is _. On day 20, the yolk finishes being fully absorbed into the chick. This is what makes it possible for a hatchling to be able to survive without food or water for several hours. Its at this point that you may start to see a hole in the shell as the chick begins to

8、ls. Chicken eggs have an incubation period of about 21 days and can be hatched in a specialized incubator under carefully monitored conditions.Selecting Eggs for HatchingTake the size of the eggs, their shape, the cleanness and condition of the shells into account, and the breed of hen you wish to o

9、btain. Large eggs hatch poorly and small eggs produce small chicks. The eggs with cracked or thin shells have difficulty retaining the moisture needed for proper chick development,and also make it easier for disease to penetrate.The eggs should be selected from breeding hens that are well developed,

10、 mature and healthy; and they should produce a high percentage of fertile eggs.Preparing the IncubatorBefore starting to hatch the chicken eggs, be sure the incubator is working properly, and you know how to operate it.Do not place it near a window where it will be exposed to sunlight. The suns heat

11、 can raise the temperature high enough to kill the developing embryos.ChineseProfession Zoom InPart 2孵化箱孵化小鸡孵化鸡蛋是一个需要妥善规划、细心照料、灵活机动和仔细观察技巧的非常有意义的过程。通过孵化箱严控温湿度,经大约21天,鸡蛋成功孵化为小鸡。鸡蛋的选择要考虑鸡蛋的蛋形指数、清洁卫生、蛋壳质量和鸡品种。过大鸡蛋孵化率差,过小鸡蛋易产生弱雏;破壳或薄壳蛋不能保持小鸡正常生长所需的水分,也是疾病的诱因。应选取健康鸡群所生的蛋,这样易提高蛋的受精率。准备孵化物孵化前,首先确保孵化箱的正常运转和

12、知道如何操作。不要将孵化箱放在靠近阳光照射的窗户附近。太阳的热量可以提高温度到足以杀死发育中的胚胎。EnglishProfession Zoom InPart 2ReadingTemperatureThe most crucial factor during incubation (especially during the first week) is the temperature. The optimal temperature in the first two weeks is 38.9. An increase in temperature at the same time as a

13、 drop in humidity can have disastrous results. Drops in temperature will delay hatching but are less harmful than increases in temperature. From day 19 onward, the temperature should be reduced to 36.1 because the chicks will be producing their own heat.HumidityThe moisture level in the incubator sh

14、ould be about 50 to 65 percent relative humidity (60 percent is often considered ideal). Moisture is provided by a pan of water under the egg tray. The water surface should be at least half as large as the surface of the egg tray. Add warm water to the pan as necessary. If more humidity is needed, i

15、ncrease the size of the pan or add a wet sponge. Humidity adjustment can also be made by increasing or decreasing ventilation.VentilationVentilation is adjusted by increasing or decreasing openings in the sides or top of the incubator. Normal air exchange is needed during the embryos development and

16、 should be increased as the chicks begin to hatch. The embryos need oxygen and produce carbon dioxide. However, the correct relative humidity must be maintained until most of the chicks are out of their shells. Do not open the incubator unless necessary during the last 3 days of incubation.ChinesePr

17、ofession Zoom InPart 2温度在整个孵化期(尤其是第一周),温度是至关重要的因素。前两周的最佳温度是38.9。温度过高过低都可能对胚胎产生毁灭性的打击,温度过低会延长孵化期,但较之温度升高而言,危害要小一些。从第19天起,温度应该降低到36.1,因为小鸡会产生自己的热量。湿度孵化器应保持50%60%的相对湿度(通常认为60%是理想值)。水分由蛋盘下面的一锅水提供。水面应至少是蛋盘表面的一半大小,根据需要向锅中加入温水,如果需要更多的湿度,请增加锅的尺寸或添加湿海绵。也可以通过增加或减少通风来进行湿度调节。通风通风是通过增加或减少孵化器两侧或顶部的开口来调节的。在胚胎发育过程中

18、需要正常的空气交换,并且随着雏鸟开始孵化而增加。胚胎需要氧气,产生二氧化碳。然而,必须保持正确的相对湿度,直到大多数小鸡离开蛋壳。在孵化的最后3天内,除非必要,否则不要打开孵化箱。 EnglishProfession Zoom InPart 2ReadingTurning the EggsMake sure that the eggs are turned 3 times a day for the first 19 days. After that, it is no longer necessary to turn the eggs. It is the most important th

19、at you turn the eggs within regular time. Turning the eggs is very easy with an automatic egg turner. You can also turn the eggs by hand. It should be done gently but you should not lose time. To prevent the incubator from cooling down, leave the door of the incubator closed as much as possible when

20、 you turn the eggs.Candling the EggsCandling is best started on the 9th day of incubation, and remove any infertile eggs or eggs containing dead chicks from the incubator. A second candling should be done after 14 to 18 days of incubation. Once again remove all the dead embryos and check the humidit

21、y levels. Do not candle the eggs after the 18th day so as not to disturb the growing chicks.Keeping RecordsIt is very important to write down the date on which the eggs are put into the incubator. Note the temperature and humidity twice a day. If hatching results are poor at the end of the incubatio

22、n periods, your records will tell you whether the temperature or the humidity is to blame. Normally hatching rates vary from 50% to 70%.ChineseProfession Zoom InPart 2翻蛋确保鸡蛋在头19天每天翻3次。在那之后,再也不需要把鸡蛋翻过来了。这是最重要的,你把鸡蛋在规定的时间内。用自动翻蛋器转动鸡蛋很容易。你也可以用手把鸡蛋翻过来。这件事应该做得很轻,但你不能浪费时间。为了防止孵化器冷却,当你打开鸡蛋时,尽可能地关闭孵化器的门。照蛋孵

23、化第9 天开始进行光照,剔除无精蛋、死精蛋。孵化1418 天后应进行二次照蛋。再次清除所有死胚蛋,检查湿度水平。18 天后建议不照蛋,以免扰乱正在生长的小鸡。做记录记录入孵时间很重要。注意每天记录温度湿度两次。如果在孵化期结束时,孵化率低,你的记录将告诉你温度或湿度水平是否出现了问题。小鸡的正常的孵化率一般介于50%70%之间。EnglishProfession Zoom InPart 2VocabularyProfession Zoom InPart 2Phrases and Expressionstake . into account 考虑;重视carbon dioxide 二氧化碳aut

45、栖息和觅食,鸡群能够行为正常非常重要。许多禽类消费者不再希望看到过度拥挤或者受虐的大型商业农场。Career Zoom InPart 3ReadingHow to Become a Poultry FarmerThere is no formal education required for becoming a poultry farmer, but there are a lot to learn before jumping into the role.
