Selecting high-quality and healthy chicks is the key link to eliminate sick chickens and improve the brooding rate. The selection of excellent chicks directly affects the growth and survival rate of chicks, and also affects the production performance of adult chickens, which is directly related to the efficiency of raising chickens. Therefore, to prevent Marek's disease in chickens, Marek's vaccine should be inoculated within 24 hours. In order to reduce the cost, some chicken vaccine manufacturers do not use this vaccine at all, or use ordinary freeze-dried vaccine, which has low price and unsatisfactory epidemic prevention effect. Once chickens break out in adulthood, we must pay attention to the weather during the transportation of chickens. You can't bring chickens when the weather is bad. If you encounter bad weather, you should arrive at your destination as soon as possible, especially paying attention to the uneven air distribution inside the car.
The selection of chicks is mainly about the selection of breeds and health status. When removing sick chicks, we should pay attention to the mental state of chicks during transportation, so as to find problems in time and take corresponding measures. Chickens have low body temperature, weak thermoregulation ability and weak cold resistance. Immune function is not perfect, and disease resistance is weak; Sensitive to the external environment, timid. In view of the above, put them in a special chicken basket, and there are about 100 chickens in a basket. In winter, the outside should be surrounded by cloth strips to keep warm, and in summer, it is not necessary to cover it too tightly. Pay attention to ventilation.
