肉鸡标准化育雏、饲养、屠宰加工产业化基地项目可行性研究报告(18)

差，开始应喂易消化饲料。雏鸡生长发育很快，所以在日粮配合时应尽量使用高能量、高蛋白质以及含维生素、微量元素充足，容易消化，营养全面的饲料。

（3）雏鸡对外界环境反应敏感，在饲养过程中，要创造安静的环境，以防止不必要的刺激所造成的损失。

（4）雏鸡体小娇嫩，抵抗力差，并易感染各种疾病。应精心饲养管理，提高体质并做好各项卫生防疫工作。

2、肉鸡标准化饲养

（1）选择适宜的鸡场场址，创造适宜的生活环境，以利于鸡的生长发育和防止鸡群感染疾病。选址应在地势高燥、采光充足和排水良好，隔离条件好的区域，鸡场周围无大型化工厂、矿厂等污染源，鸡场应严格执行生产区和生活区相隔离的原则。鸡舍具备良好的防鼠、防虫和防鸟设施。

（2）引进优良的鸡雏。引种须从取得《种畜禽生产经营许可证》的种鸡场和孵化场引进，以确保雏鸡的质量。同一鸡舍或同一鸡场只饲养同一批次的鸡，采取同时进场、同时出场的管理制度。

（3）饲喂优质的全价配方饲料。鸡饲料应符合无公害食品 肉鸡饲养饲料使用准则Ny5042相关标准要求，强调上市前7天，饲喂不含任何药物及药物添加剂的饲料，一定要严格执行停药期，以利于生产优质、安全、无公害的肉鸡产品。

（4）实施科学的饲养管理①肉鸡饲养要采用笼养技术，搞好鸡舍的饲养环境。②肉鸡饲养管理技术应符合Ny/T5043

球还是水球？ The Wayle is a small river that cuts across the par near my home. I like sitting by the Wayle on fine afternoons. It was warm last Sunday, so I went and sat on the river ban as usual. Some children were playing games on the bank and there were some people rowing on the river. Suddenly, one of the children ed a ball very hard and it went towards a passing boat. Some people on the bank called out to the man in the boat, but he did not hear them. The ball struc him so hard that he nearly fell into the water. I turned to loo at the children, but there weren't any in sight: they had all run away! The man laughed when he realized what had happened. He called out to the children and threw the ball backto the banLesson31 Success story 成功者的故事 Yesterday afternoon Fran Hawins was telling me about his experiences as a young man. Fran is now the head of a very large business company, but as a boy he used to work in a small shop. It was his job to repair bicycles and at that time he used to work fourteen hours a day. He saved money for ears and in 1938 he bought a small work-shop of his own. During the war Frankused to mae spare parts for aeroplanes. At that time he had two helpers. By the end of the war, the small work-shop had become a large factory which employed seven hundred and twenty-eight people. Fransmiled when he remembered his hard earlyears and the long road to success. He was still smiling when the door opened and his wife came in. She wanted him to repair their son's bicycle! Lesson32 Shopping made easy 购物变得很方便 People are not so honest as the once were. The temptation to steal is greater than ever before--especially in large shops. A detective recently watched a well-dressed woman who always went into a large store on Monday mornings. One Monday, there were fewer people in the shop than usual when the woman came in, so it was easier for the detective to watch her. The woman first bought a few small articles. After a little time, she chose one of the most expensive dresses in the shop and handed it to an assistant who wrapped it up for her as quicly as possible. Then the woman simply took the parcel and walked out of the shop without paying. When she was arrested, the detective found out that the shop-assistant was her daughter. The girl' gave' her mother a free dress once a week ! lesson33 Out of the darkness 冲出黑暗 Nearl a week passed before the girl was able to explain what had happened to her. One afternoon she set out from the coast in a small boat and was caught in a storm. Towards evening, the boat struc a roc and the girl jumped into the sea. Then she swam to the shore after spending the whole night in the water. During that time she covered a distance of eight miles. Early next morning, she saw a light ahead. She knew she was near the shore because the light was high up on the cliffs. On arriving at the shore, the girl struggled up the cliff towards the light she had seen. That was all she remembered. When she woke up a day later, she found herself in hospital. Lesson34 Quic work 破案“神速” Ted Robinson has been worried all the weekLast Tuesday he received a letter from the local police. In the letter he was asked to call at the station. Ted wondered why he was wanted by the police, but he went to the station yesterday and now he is not worried any more. At the station, he was told by a smiling policeman that his bicycle had been found. Five days ago, the policeman told him, the bicycle was picked up in a small village four hundred miles away. It is now being sent to his home by train. Ted was most surprised when he heard the news. He was amused too, because he never expected the bicycle to be found. It was stolen twenty years ago when Ted was a boy of fifteen ! Lesson35 Stop thief捉贼！ Rov Trenton used to drive a taxi. A short while ago, however, he became a bus-driver and he was not regretted it. He is finding his new work far more exciting. When he was driving along Catford Street recently, he saw two thieves rush out of a shop and run towards a waiting car.

The thieves' car was badly damaged and eas to recognize. Shortly afterwards, the police stopped the car and both men were arrested.
