At the same time, it should also meet the other nutritional needs of chickens, especially vitamins, minerals and other trace elements in the nutritional balance, to ensure that feed nutrition can fully meet the needs of chickens.
3 Strengthen feeding and management By improving facilities such as heating, ventilation, cooling, and lighting, improve the responsibility of the keeper and ensure that the temperature in the house is maintained within the range of 10 to 25°C. In the cold winter, under the premise of ensuring the temperature, increase the ventilation as much as possible to achieve ventilation and reduce the humidity. During the hot summer months, we can start the wet curtain cooling system and increase the ventilation to maximize the wind speed and reduce the temperature. At the same time, in the daily management work, the flock should be observed at any time and the flow of the drinking water system should be ensured to ensure that sufficient and good-quality drinking water is supplied to the flock throughout the day, and the drinking fountains should be kept clean. In addition, the density should be appropriate, the light can not be too strong and so on. Only in this way can you avoid the stress caused by temperature, humidity, ventilation, drinking water, light, etc. to the flock, and you can avoid the phenomenon of de-feathering.
