4.2.1 The chicks should come from breeder farms that have a breeding livestock and poultry production and operation license issued by the provincial animal husbandry department. The procedures for the introduction of breeder chickens and the sale of product chickens are complete. The chicks are directly transported to the commodity farm by a special box-type chick transport vehicle after hatching and packing, without going through the resale or transshipment links.
4.2.2 Before receiving the chicks, the brooding room must be disinfected and the necessary equipment and supplies must be prepared. 4.2.3 The chicks must be transported to the brooding room within 24 hours after hatching. The temperature of the storage environment of the hatching and curing chickens and the temperature in the transport vehicle during transportation should be maintained at 21℃-~26℃
4.3 Feeding
Use timed feeding to ensure that the chickens can eat freely; place the feed trough correctly, so that the chickens can eat at 3 m. The height of the feed trough should be gradually increased with the age of the chickens. The feed trough should be 2m higher than the chicken back or at the same height. 4.4 Drinking water
The drinking fountain should be cleaned and disinfected every 3 days. The height of the trough should be adjusted with the age of the chickens. The drinking trough should be 2cm higher than the chicken back or at the same height.
4.5 Ventilation
The ventilation volume should be accurately designed according to the age, weight and number of broilers. The ventilation volume of the chicken house should be designed based on the maximum ventilation volume in summer (see Table 5), and a sufficient number of fans should be designed and installed according to the ventilation volume and fan type. It is advisable to use longitudinal ventilation wet curtains to reduce humidity. Decay 5 Every 1 000 Ventilation volume per broiler Chicken weight/kg
4.6 Lighting
Minimum ventilation volume in winter/(m2/min)
Maximum ventilation volume in off-season (m/min)
Light sources can be incandescent lamps, fluorescent lamps and commercial steel lamps. Chicken farms with conditions can use light timers to provide lighting at set times. Open chicken houses can refer to the continuous lighting system in Table 6, and dark or closed chicken houses can refer to the intermittent lighting system in Table 7. 4.7 Temperature
The temperature for broiler maintenance is 1d~-3d, 34℃~354d~71.32℃~33 and then decreases by 2℃3℃ every week. When the temperature reaches 20~21℃GB/T19664—2005
Stop cooling and keep this temperature constant. In summer, the outside temperature is high, and the temperature decreases by 3℃ every week. In winter and spring, the outside temperature is low, and the temperature decreases by 2℃ every week. 4.8 Humidity
The temperature of the brooding case is high, and the humidity of the chicken is low, which is not conducive to the growth of the chicken feathers. The humidity can be increased by boiling water to produce steam, or disinfectants can be used to disinfect the chickens, which can not only purify the air, but also increase the humidity of the chicken house. Relative condensation of the chicken house: 1~10 days, 70%; 11~30 days, 65%; 31 days~=45 days, 60%: keep 50%~-55% in the future. The ground or bed surface in contact with the chickens should be kept dry. 4.9 Capture and transportation
Stop feeding 4h~-6h before the chickens are captured and caged, stop water supply 1h~2h before lifting the chickens, and lift or remove all the tools before catching the chickens. Be gentle and steady when catching the chickens, putting them into cages, handling, loading and unloading, so as to prevent squeezing and suffocation. Table 6 Lighting program for open chicken house
