There is a temperature difference between the upper, middle and lower three-tier chicken cages in three-dimensional breeding, and the lower the outdoor temperature, the greater the temperature difference. Brooding chicks are generally at the highest level, because the highest level has the highest temperature, which helps to save heat. On the first day when the chicks enter the farm, the temperature should be controlled at 33～34℃. The temperature can also be adjusted according to the state of the chicks. When the temperature is right, the chickens are evenly distributed, lively, and have a strong appetite; when the temperature becomes low, they shrink their necks and bow their backs and concentrate on the heat source. Squeezing each other, the body trembles; when the temperature is too high, the amount of water drinking increases, the appetite decreases, the breathing speeds up, and the neck feathers are water-soaked. In the first week, the temperature drops to 30~C, and thereafter it drops by 2°C every week. The three-dimensional breeding density is high, which is 1~2~C lower than the flat rearing temperature. It should avoid causing heat stress and reducing the amount of food purchased.
Three-dimensional breeding broilers mostly use whole sports chicks. When the density of chicks is too large, group them in a timely manner to ensure that the weight of the chicks is even. The first grouping is generally 12-16 days old. The grouping is too early. Due to the small size, it is easy to be in the gap of the breeding cage. Drilling out will also cause a waste of space, thereby wasting energy. For the second grouping, at the age of 25 to 28 days, the principle of “remaining weak and not strong” is adopted when grouping. The healthy young are placed in the lower level and the weak young are left behind. In summer, due to the high temperature, the cages can be separated appropriately. In winter, due to the large temperature difference between the upper and lower layers of the chicken cage, the time of cage separation can be delayed appropriately, and one more cage is placed in the lower cage to reduce the temperature difference between the upper and lower layers.
The key to successful breeding lies in ventilation. Reasonable ventilation can eliminate harmful gases, control temperature, and reduce the occurrence of ascites, chronic respiratory diseases and colibacillosis. The three-dimensional breeding unit has a large area of chicken house, so ventilation is more important. Within 24 hours after the chicks enter the farm, due to the large space for the whole sporting chicks, no ventilation is required. As the age of the chickens increases, gradually increase the amount of ventilation, adjust the position and size of the air inlet, day, night, cloudy, sunny, spring, summer, autumn and winter , It is necessary to keep adjusting in time to achieve the air
in the house without peculiar smell, no glare, no hypoxia, and more comfortable feeling, creating a good growth space for the chickens, enhancing the body’s disease resistance and reducing the occurrence of diseases.
Medium-sized chicken farms have advanced equipment, but advanced equipment alone may not be able to raise chickens. With the continuous improvement of scale and automation, breeding failures are not uncommon. The key lies in the organic combination of people and equipment. The operator must not only be familiar with the principle of the equipment, but also observe frequently, because there is a certain error between the temperature controller and the temperature value in the chicken house. This error value must be adjusted to the minimum so that the temperature of the chicken house can be adjusted to the chicken’s maximum Suitable temperature for growth. In addition, the operator must be proficient in the use of equipment and the feeding procedures of chickens at various stages, and be able to detect and repair equipment failures in time. Once equipment is used improperly or equipment malfunctions, it will cause huge problems. Economic loss.
After the chicks enter the house, ensure that they can drink water within 2 hours. For some weak ones, they can drink water manually by dipping their mouths. The purpose is to let the chicks learn to drink water as soon as possible. After the chicks are in the house, they must drink water first, and then feed them. This is conducive to the digestion of the chicks. 2 to 3 hours after drinking the water, put the feed in the opening tray for the chicks to peck. The three-dimensional breeding averages 25 chicks. Small troughs must be fed less frequently to prevent feed contamination and mildew.
Chicken poultry farming equipment manufacturers tell farmers The three-dimensional breeding chicken house adopts artificial light, which is convenient to control the light time. For the first seven days of brooding, 24 hours of light is generally used, and then gradually dripped for 22 hours. The purpose is to let the chicks get used to the dark environment and prevent the chickens from panic and crowding due to sudden power failure. Crushing casualties, and then gradually increased to 24 hours of light a week before the hurdle.
