How to raise chickens? The four principles of scientific feeding management technology of princess chicken are comprehensive and advanced, and the whole production of princess chicken is divided into two stages: incubation period and stocking period. The two stages are omni-directional and system-wide, that is to say, in the henhouse, the same free-range website only provides unified feed, realizes the immune system on the same day, and adopts the same management measures in the market. Finally, on the same day, behind the henhouse, the website and utensils were thoroughly cleaned, cleaned and disinfected.
2 ~ 3 weeks after feeding, the stocking time and density can be appropriate, and the specific stocking age depends on the external temperature and the physical condition of the chicks. Attention should be paid to "step by step" in the initial stage of stocking, gradually increasing the outdoor activity time of chickens, and delaying or reducing the stocking time in bad weather. Generally, after 35 days of age, when the temperature is above 20℃, it can be stocked for a whole day. According to the actual stocking statistics, 90% of chickens move in the range of captivity, and the diameter of the range of captivity is 200m·m, so each batch 1000 chickens can be divided into 3-5 groups, with 200-300 chickens in each group and 20-30 chickens per mu.
In order to ensure good meat quality and taste, Huangfei chicken is usually sold at about 90 days old and weighs about 1 kg. In practice, according to the weight of the chicken, it can be fattened 3 weeks before the market. At this stage, the range of activities of chickens should be reduced or all chickens should be raised in captivity, and chickens should be free to provide high-quality feed and feed, and the metabolic energy level of feed should be 12.0 mj/kg to improve the fat of broilers.
