The core message: For parental broiler breeders, detailed management of the brooding period is particularly important for the chick's future health, evenness, and production performance, including details of brooding, brooding techniques, use of brooding equipment, and precautions. The following eight aspects are elaborated. For parental broiler breeders, detailed management of the brooding period is particularly important for the chick's future health, evenness, and production performance, including details of brooding, brooding techniques, use of brooding equipment, and precautions, etc., from the following eight Aspect elaborated. First, closed brooding All brooders eat, stay and work in the brooding house for 28 to 35 days. Special vehicles transport feeds. It is best to prepare feeds for brooding in advance and disinfect materials used by brooders. Everything must be strictly disinfected before entering the product. Second, the amount of brooding supplies, placement and use 1, brooding umbrella Electrothermal type, 500 chicks per umbrella; LPG infrared type: 500 to 1,000 chicks per umbrella, infrared height 1.0 to 1.3 meters, angle 30 degrees. Adjust the height of the umbrella depending on the ambient temperature. Depending on the ambient temperature, the length of the umbrella heating time can be automatically adjusted or adjusted manually. Always check the liquefied gas tank tee, whether the joints are leaky, whether the brooding umbrella can be used to light the fire, soapy water or shampoo. Hanging natural gas heating should pay attention to the uniform temperature in the heating area. When necessary, add iron or steel skin under the heating tube to disperse the heat radiated from the radiation. 2, temperature and humidity meter Each one of two branches or one column should be hung on the edge of the fence (hygrometer and mercury thermometer). 3, fence board From 0 to 3 days of age, 10 to 20 eggs per 800 young chicks, and depending on the ambient temperature and the status of the chicken at any time thereafter. The fence boards are connected by an electrical plastic tie or a 20-gauge wire. The lower corner of the connected fence plate cannot be drilled, and it is tightly packed with plastic cloth. The fence board should be placed in a stable structure, such as a zigzag line. Do not form a very narrow angle between the two plates. 4, scaffolding brooding net or gauze Between the nets to overlap 25 to 30 cm. Overlap at the overlap. If there are loopholes in the net, they must be repaired to prevent chicks from leaking under the scaffold. 5, tray and waterer Open food dish: 100 pieces/piece in 1 to 7 days, plus auxiliary feeding equipment to ensure sufficient material level. Drinking fountain: A 4 litre drinking fountain for 50 chicks within 1 to 7 days. The trays and drinking fountains should be staggered and placed at a distance from each other. At least two chickens can feed and one chicken can pass. When using an electric brooding umbrella, the tray and the waterer are placed on the edge of the umbrella. Prepare a liter container to fill the drinking fountain (plus accuracy). 6, bedding When brooding on litter, the litter thickness should be at least 2cm (not on the ground, at least 8cm above the ground). Tiles or wooden blocks should be placed under the drinking fountain to prevent the litter from contaminating the water fountain. Third, the temperature Warm the brooding house before entering the brood. Winter is 3 days ahead of schedule. Warming can be done one day ahead of the summer. If the temperature in the house is difficult to raise, the door and the exhaust fan can enter the cold air. You can leave two plastic sheets on both ends. The temperature of the brooding house is above 28 degrees, and the temperature of the brooding under the umbrella is 32-34 degrees. The temperature drops 3 degrees per week until 21 to 23 degrees. Depending on the temperature of the flock, the temperature of the flock is adjusted to give temperature. If the temperature difference between day and night is large, or when the outside is cold, increase the temperature by 2°C at night. When the temperature in the house is relatively low, turn on the attractant light to allow the chicks to focus under the umbrella. Proofreader thermometer is best mercury thermometer. Frequently check the temperature and distribution of the birds (especially the first few days) to prevent large temperature differences at different times in the home. When the chickens are piled up, warming measures and comprehensive insulation measures are adopted. Check to prevent air leakage caused by thief caused by a certain temperature inside the house than the end, it is best to make the temperature inside the house basically the same. Fourth, humidity The first 1 to 7 days of brooding, relative humidity of 60% to 70%, is particularly important for long-distance transport of chicks and chicks hatched by newly hatched chickens. When the humidity is relatively low, it is necessary to sprinkling and humidifying, and when humidifying, consider the area to be sprinkled and the location of watering. For fear of cooling and spreading hot water, cool the water by cooling. The relative humidity was calculated using a hygrometer. (equipped with the corresponding form). Look at chicken feet, quail, and feathers to determine if the humidity in the home is appropriate. Human body feeling and breathing can also judge whether the humidity is appropriate. Humidity is too high and ventilation is available. Spray humidification is also feasible. Fifth, drinking water Promote drinking water from 0 to 3 days old. When there is no drinking warm water condition, the temperature of the water can be considered in the house. Chickens should have a drinking temperature of 20 degrees or more, but do not exceed the house temperature. After the chicks entered the pen, they were fed with water for feeding. Drive or train the chicks to drink water. When necessary, teach each chicken to drink water. Check the chick's drinking status, find out how to touch, kill on the second day, and dissect the chicken. The first time drinking water to add 5% to 8% of glucose (sweetened water is best to drink within 3 hours, only drink once), especially the long-distance transport of young and newly hatched eggs hatchlings, you can drink 2% to 5% brown sugar water. After drinking glucose water, you can drink electrolytic multi-dimensional or clear water, do not advocate drinking antibiotics on the first day, you can drink the next day (according to their own environment to consider whether the first day of medication). To add medicine to the water, the dispenser should be distributed to each drinker. Every time you add water, you should not use too much water. In the first few days, it is advisable to use 1.5 liters at a time in order to change the water frequently and brush your drinking fountains to prevent bacterial growth (especially necessary after changing the water). Clean the water dispenser at least twice a day and disinfect it with a non-toxic disinfectant. Drinking fountains should be placed to prevent overflow. Drinkers should be distributed evenly, not far from the fences, and the trays should not be too close (at least two chickens eat, drink, and a chicken passes). In the first few days, use stronger light to induce chickens to drink more water and be familiar with the ingredients (no less than 60 LUX or 18 watts of energy-saving lamps). Pay close attention to changes in the amount of drinking water in the flock and record the amount of drinking water. After the chickens came off the ground (according to the height of the scaffolding), the main observation was whether the chickens could put 100% on the scaffolds or they could use 3 days to catch chickens on the scaffolds to prevent dehydration. 4th to 7th days of drinking VC, is conducive to long chicken skeleton and improve egg hatching hatching rate. When the drinking fountain is changed to the automatic drinking fountain, the original drinking fountain should be gradually removed near the automatic drinking fountain to let the chicks become familiar with the environment. Regularly clean the drinking water system after activating the automatic waterline. Six, feeding Each tray is provided with 100 chicks (0 to 7 days old), and the feed is sprinkled on the auxiliary material or color strip cloth for the first three days. Feed 4 to 6 times daily within 7 days and gradually reduce to once daily. 1 to 3 years 6 times, 4 to 7 days 5 times, 8 to 10 days 4 times, 11 to 14 days 3 times, 15 to 17 days 2 times. Often notice that there is no mildew in the material, agglomeration (feeding workers check the material), found that the problem stopped feeding the material. Wipe the pans at least once a day. Record the time it took to finish the meal. Every time Tim finished the material, he immediately rushed to the chicken to eat, let each chicken to eat material, and patrol the situation of eating. The thickness and the number of times the material was added during the break were increased (now the hen can continue to scold the cock and burn it). In the first few days, the lights are stronger and guide the chicks to feed. According to the feed standard for each feeding amount, the number of feeding trays is uniformly given to each tray, and each column is divided into materials, and the material in the tray is to be evenly distributed. Check whether the material level is insufficient when feeding. Add the material tray, expand the column (preferably according to the age of expansion, add the tray). When patrolling, find smaller chickens and feed them individually in one column to increase uniformity. The refueling finished in three days. Various vitamins (drinking water or spices) should be added when stress, such as immunity, percussion, etc. occurs. Seventh, light The distribution of lights should be reasonable, and cross-distributions should be made so that the light intensity should be uniform. Illumination can be reduced to 8~10 LUX after 7 days of age. Timely replacement of bad bulbs, adjustment of the clock according to the lighting plan, strict implementation of the brooding light plan. It is forbidden to leak light at the air inlet and exhaust fan hood. The light intensity is not less than 60 LUX for 0 to 7 days, and it is 8 to 10 LUX until 7 days later. When the length of light is reduced, it will be reduced in the morning and in the evening. It is recommended for 8 hours (8:00~16:00). Eight, ventilation 0 ~ 7 days less ventilation (related to the structure). When ventilating, take into account the temperature, humidity, and air pollution (people can feel bad air, ammonia smell, stuffiness, etc.). When the temperature is higher: a. Warming and ventilation before using warm umbrella warming; b. Change the air when the weather is warmer; c. This can be done by a few short ventilations. Ventilation should not cause large changes in the temperature inside the house. In cold days, ventilation should be repeated for a short period of time to achieve the purpose of ventilation. Do not let the wind blow to the body of the bird, cover the air inlet, and let the wind blow upwards. The wind speed should not be too fast, especially when the outside temperature is low (the inlet can be smaller and the fan outlet smaller). Temperature-controlled ventilation equipment can be used, but these equipment must be accurate, calibrated and often checked, and the best use of the AC2000 environmental management equipment is available. General: The management of the first 4 weeks of age of the parent broiler breeder chicken is an important stage of the entire feeding cycle, which has a direct impact on the performance of the entire chicken group. The chickens in the brooding period can grow healthily and rely on the meticulous management of the keeper. , detail management is the only way to achieve the goal.
