世界各国现代化养鸡的实践证明,要想提高养鸡的经济效益,获得较佳的产量,首先要确保饲料的营养成份全面;其次,要考虑鸡群直接所处的气候环境因素,如温度、湿度、空气、光照等外界气象条件优劣及适宜的程度。在生产实践中,充分运用有利的自然环境和人工创造适宜的小气候条件,使鸡生长发育与环境保持生理平衡。一、鸡的生理适应性应与环境温度保持平衡鸡根据温度变化而不断调整采食量,既要把生理活动中和在消化食物时所产生的热
The practice of modern chicken in various countries in the world proves that, in order to improve the economic benefits of raising chickens and obtain better yields, we must first ensure that the nutritional content of the feed is comprehensive. Secondly, we should consider the climatic and environmental factors directly affecting the chickens, such as temperature, Humidity, air, light and other external weather conditions, the merits and desirability. In production practice, make full use of favorable natural environment and artificial creation of suitable microclimate conditions, so that the growth and development of chicken and the environment to maintain a physiological balance. First, the physiological adaptability of the chicken should be balanced with the ambient temperature Chickens according to the temperature changes and continue to adjust the amount of feed, it is necessary to neutralize physiological activities and in the digestion of food produced by the heat
