Scope

Main Technical Content: 6. Feeding and Management 6.1 Feeding Method: Combination of cage-based and free-range feeding. 6.2 Feeding and Management during the Chick Rearing Period 6.2.1 Chick Rearing Method: Follow the principle of maximum ventilation at suitable temperatures. Monitor situations such as chicks panting, excessive water consumption, and high ammonia levels in the coop, and immediately ventilate the coop when needed. 6.2.3 Place the thermometer close to the ground (i.e., at the back of the chicks) for the first 1–3 days (34–36°C), then reduce the temperature by 0.2°C daily from 4 to 14 days, and finally reduce it by 1°C daily from 15 to 30 days until normal temperature. Preheat the coop before introducing the chicks. 6.2.2.2 Use either floor-based or net-based rearing methods. Provide infrared lamps, coal stoves, or geothermal heating, and ensure the coop floor and bedding are dry. 6.2.2 Environmental Conditions 6.2.2.1 Temperature and humidity should be controlled at 60%–70%. 6.2.2.3 Lighting: Provide 24-hour lighting for the first three weeks, then gradually reduce it by one hour per day until natural light. 6.2.2.4 Ventilation: Maintain a rearing density of 40 chicks/m2–50 chicks/m2 at 1 week, 30 chicks/m2–40 chicks/m2 at 2 weeks, and 20 chicks/m2–30 chicks/m2 at 3 weeks. 6.2.3 Water and Feed 6.2.3.1 Use full-nutrition chick feed (compliant with NY 5032) during the rearing period. 6.2.6 Beak Trimming: Conduct beak trimming around 20 days of age. Ensure the flock is healthy before trimming and administer antibiotics or stress-reducing medications such as VK3. During trimming, prevent chicks from crowding together or bleeding. 6.2.7 Castration: Castrate male chicks aged 20–30 days. 6.2.8 Selection Process 6.2.8.1 Day 1: Select healthy chicks with well-contracted navels. 6.2.8.2 Weeks 5–6: Select healthy individuals with high crown height and good development. 6.2.8.3 Weeks 8–10: Select healthy individuals with feathe
