Chai chicken brooding

The brooding period is the key to the breeding of chickens and the relatively high technical requirements of the breeding period. Understanding and mastering the brooding process of the chicks is crucial for improving economic efficiency. First, choose the appropriate brooding time and brooding methods 1. About brooding time Hebei Province and surrounding areas, the general choice of broiler chicks in the spring (March to May). Because the climate was dry during this time, the temperature rose and the sunshine was sufficient, and the chicks grew well. In the middle of the brooding period, the temperature is appropriate and the time for outside activities can be increased. Spring and early sexual maturity, use a long time. When the peak of egg production for the chicks selected during this time comes, they are catching up with the four festivals of Mid-Autumn Festival, National Day, New Year's Day and Spring Festival. The eggs sell well and sell at a high price. If spring chickens do not sell well, chickens can be eliminated before and after the Spring Festival the following year, since the price of chickens is the highest. It is also possible to use the second egg production peak of the second year of the spring chicken and eliminate all the chickens from June to July. However, this overlaps with the timing of the brooding period for the next batch of chicks, requiring farmers to have larger venues and stronger funding. 2. About brooding methods Chai chicken brooding uses two brooding methods. One is the litter ground backyard. In the brooding room floor, wheat straw, sawdust, corn husks, etc., are laid on the floor of the brooding room as litter. The whole brooding period chicks live on the litter, and the litter is replaced after the brooding. Most of these brooding methods are for small-scale farmers or mountain farmers. The other is cage raising. A brooding cage is set up in the brooding room. The brooding cage is a laminated type, which is generally 4 layers with a height of 33 cm in each layer. The upper and lower two-layer cages are provided with a manure-bearing plate, and the gap between the layers is 5 cm to 7 cm. Most of these brooding methods are scale-cultivation households or farmers who have changed from raising “chicken” to raising chickens. Second, to do a good job before brooding 1. Brooding articles preparation. 1 feed. Brooding can be used with full-price compound feed or self-contained young feed. Cumulative total feed consumption from 0 to 6 weeks old for Chai Ji is 750-800g/kg. Full-price compound feed market price is 0.79 yuan/500 g to 0.85 yuan/500 g. Self-conforming feed should pay attention to the selection of non-polluting, non-deteriorating raw materials, and require uniform mixing, proper particle size, and good palatability. Feeding time with a single feed can not be too long, it is appropriate to eat within one week. Here is a case of Hebei chicken as an example of a chick. Feed formulations for weeks to 6 weeks old are for reference only (see Table 1). 2 vaccine. The vaccines used during the brooding period of the chickens include Marek’s disease vaccine, Newcastle disease vaccine, infectious bursal disease vaccine, infectious bronchitis vaccine, and fowlpox vaccine. Vaccine costs, including Marek’s disease vaccine, range from 0.16 yuan to 0.18 yuan per chick, and the cost of Marek’s disease vaccine is 0.06 yuan to 0.08 yuan. The vaccine used should be based on the immunization procedures established for the prevalence of the local disease (see Table 2). 3 drugs. The sterilized drugs commonly used in brooding period include benzalkonium bromide and 100-toxin-killing drugs, such as gentamicin, norfloxacin, terramycin pure powder, electrolytic multidimensional, and glucose. The cost of drugs for brooding broiler chickens ranges from 0.03 yuan to 0.04 yuan per chick. 4 chicken costs. Take Hebei Hebei chicken as an example, male and female mixed chicks cost 0.95 yuan to 1 yuan each, 2 to 2.1 yuan for the identified mother and chick, and 0.3 yuan to 0.4 yuan for the identified male chicks, all of which are played against Malik. Price after the vaccine. If you buy eggs, contact the hatchery for hatching, each egg is about 0.6 yuan, the processing fee is 0.15 yuan each, the identification fee is 0.03 yuan each, according to the identification of the mother and young bird, the vaccine for Marek's disease is about 0.1 yuan each. . 3 other items. The brooding cage is 28 yuan/set, and the specifications of the cage can be customized as required. Generally 24 cm high, 45 cm wide and 100 cm long. Each cage can hold 45 chicks at the beginning of brooding. By the end of the brooding, no more than 25 cages can be found. The number of brooding cages depends on the amount of brooding. In addition, we need scales (30 yuan/piece), atomizers (50 yuan), continuous syringes (55 yuan/piece), push-pull trucks (100 yuan/piece), and cutting devices (300 yuan/piece). The above items are generally Every kind of one. Other items that need to be prepared include a thermometer, a stabbing needle, a drop bottle, a shroud, a newspaper, a plastic sheet (35 centimeters and 60 centimeters), a trough, a bucket, and a record book. Utilities costs 0.02 yuan for each chick and 0.03 yuan for heating fees, such as 0.12 yuan per chick for coal. 0.15 yuan, such as dry firewood can reduce the cost of 60%. In addition, early brooding costs are high and late spring costs are low. 2. Finishing, disinfection and testing of brooding houses. Each batch of chickens should be sorted, disinfected and tested for temperature before entering the chicks. First, clean up the scum, dust, etc. in the brooding room, and use 2% firebase to prevent sprinkling. All utensils should be cleaned, such as troughs, sinks, cages, etc., and placed in place. Then overhaul the water, electricity, ventilation equipment, so that the brooding house is clean, airtight, warm and ventilated. One week before the start of the brooding, the brooding house and equipment were fumigated. When the fumigation time brooding shed brooding time and pollution degree can be used potassium permanganate 14 g / cubic meter, plus formaldehyde 28 ml / cubic meter, or with potassium permanganate 21 g / cubic meter, plus formaldehyde 42 ml / cubic meter Into the ceramic basin, closed fumigation 48 hours, open the doors and windows ventilation for 3 days to 5 days. Note that when fumigating, put potassium permanganate first and then pour in formaldehyde. The fumigation process is gradually carried out from inside the brooding house. The temperature of the brooding house should be 2 days to 3 days before the hatching. If you use a sawdust furnace or ignite the fire way to warm up, you should pay attention to check whether there is smoke. The temperature of the brooding house must be raised to 32°C to 35°C during the temperature test. Before the brooding begins, drugs should be placed in front of the disinfection tank. Third, the purchase of chickens in the chick's purchase process should pay attention to the following points: 1. Before buying chicks, should first examine the breeder farm breeder eggs and eggs, it is best to learn about the previous year from the field into the young breeding Households' aquaculture conditions are examined to see if this breed of farmed chickens is popular with the local consumer market. Take Hebei Hebei chicken as an example, the weight of each breeding hen should generally be 1.25 kg to 1.5 kg, and the plumage color is color, blood color, and black color. The egg production weight is 42 g/piece to 48 g/piece, and the eggshell color is For light pink, the egg production rate is maintained at 50% to 60% on average. Each rooster weighs 2 kg to 2.5 kg, and the plumage should be dark red. When investigating breeders, it is also necessary to examine how creditworthiness of breeder farms is, such as the quality of chickens, the incidence of Marek’s disease in chickens, and the egg production rate. 2. When hatching eggs, identifying chicks after hatching, and injecting vaccines, it is advisable to purchase chickens to supervise them. 3. Choosing the weight of chicks should be more than 30g, and the individual size is uniform, the appearance is full of fluffy, shiny, clean and pollution-free, lively and active, strong when struggling with hands, soft and elastic abdomen, no deformity, disability, Responsive. If you choose the best choice for male chick feather color is pure black, so that more than 95% of chicken cockerel feathers are mostly dark red yellow. 4. The best choice for chicks is to buy them nearby. For long-distance purchases, it is best to send chicks in hatchery or breeder farms. These people have more experience and complete operating documents. They can avoid or reduce the damage of chicks during transportation. Fourth, brooding condition control 1. The temperature of 1 day of age to 3 days of brooding room temperature should be 32 °C ~ 33 °C, 4 days to 7 days of age is 30 °C ~ 32 °C, 8 days to 10 days of age 28 °C ~ 30 °C, 11 days of age ~ 14 days of 26 °C ~ 28 °C, after a weekly decline of 2 °C ~ 3 °C. There is a difference in the temperature of each part of the brooding room, and the above temperature refers to the temperature of the chick's living space. When the outside night temperature matches the brooding temperature, the heating can be stopped. This process needs to be gradually carried out. It can stop after the day and stop all day. The whole process is completed in a week. 2. Illumination requires daylight for 1 day to 3 days; 20 hours for 4 days to 7 days; 8 hours for 8 days to 21 days; turn on the lights from 6 a.m. to 10 p.m. If the natural lighting is strong, the number of lights can be reduced; after 3 weeks, natural light is used completely. When artificial supplements, the light intensity is preferably 3.5 watts to 4 watts per square meter. If multi-layer cages are used, bulbs should be installed on the side wall of the lower brooding cage. Note that the wattage of a single lamp source should not be too large, preferably 25 watts or 40 watts. 3. Ventilation In the premise of ensuring the temperature should be adhered to ventilation every day, pay attention to prevent gas poisoning. 4. Humidity Before 7 days of age, the relative humidity in the broiler house should be 60% to 65%. After 7 days of age, the relative humidity in the broiler house should be 50% to 55%. 5. If the density of chaiji brooding adopts 4 layers of cage, each cage area is 0.45 square meters, and 45 cages can be placed in each cage. The first two cages should be placed first, and the lower two layers should be reused when the density increases. No more than 25 cages per cage at the end of the brood. If ground littering is used, 250 to 300 animals per group are appropriate. At the beginning, the chicks can be divided into small groups using wooden boards to prevent crushing and avoiding occurrence of cockroaches. The brood density at the beginning of the brooding period was 40 birds per square meter and was reduced to 20 per square meter by the end of the brooding period. Fifth, brooding feeding and management 1. Feed 1 chickens for the first time feeding should be 2 hours to 3 hours after the initial drinking. When feeding for the first time, feed should be sprinkled on a diet dish or plastic sheet. The 2 chicks were fed 6 times a day and fed once every 3 hours from 6 o'clock in the morning. If they were fed 5 times a day, they were fed every 4 hours from 6 o'clock in the morning. For 31 days to 3 days of age, one-third of the half-matured millet and 2/3 of the compound feed should be fed into pellets, and each egg should be fed with one additional egg yolk. 4 After 50 minutes of feeding, remove the plastic cloth and wash and dry it. 54-day-old to 7-day-old should be fed with 1/4 half cooked millet plus 3/4 compound feed without egg yolk. After 7 days of age feed the full price batch with feed troughs. Before the age of 67 days, 0.2% oxytetracycline pure powder and 0.04% of furazolidone can be added to feed for the prevention of white peony disease. The day-to-day and day-old chickens of 111 days old and 12 days old can double the vitamin in the feed, and add another vitamin K, 200 grams per 100 kg of feed. This will help stop bleeding and prevent heat stress. 8 Cage-breeding chickens are about 40 days old. When the ground litter is brooded from 20 days to 25 days, drugs for the prevention of coccidiosis, such as Keqiu powder, Madura, etc., are added to the feed. After 3 days, the medicine is stopped for 3 days. , and then fed for 3 days, several drugs should be used alternately. 2. Drinking water 1 The first drinking time of chicks is 24 hours after hatching. It is best to use cold water for the first time drinking water and add 5% glucose water. 2 After drinking water for the first time, give the chicks norfloxacin water, add 50 grams of norfloxacin per 100 kg of water, drink for 7 days, stop for 3 days, drink for 5 days, and then drink tap water. 3 In the first 7 days, use a small bucket or a small bucket reconstructed with a canned bottle to drink water. After 7 days, use a sink to drink water. 4 Electrolyzed multidimensional cubes for chicks 2 days to 3 days before each immunization and added according to the dosage indicated in the instructions. At this time, other drugs cannot be mixed. 3. If there is a small amount of larvae, you can keep licking, for example, 200 to 300, but large-scale farming must be broken. 2 Cutting time, the chicken is suitable for 11 days to 12 days of age, such as individual chicks can be delayed back 1 to 2 days. 3 It is advisable to cut off the number of times one by one because the chickens will eat grass, eat vegetables and catch insects in the later period of production. 4 The criteria for cutting off fleas should be cut to 1/2, and the chin should be cut to 1/3. After bred, the quail should be equal to the length of the quail. If not, it will affect the price of the last culled chicken. 5 When you break your hand, hold the chick with one hand, press your thumb on the top of the head, place your index finger on the throat, and use a little force to make the chick dilute the tongue. After cutting the tip of the tip downwards, stop the bleeding on the blade. 4. Hygiene 1 Wash sinks and troughs every day. Be careful not to wash them with disinfectant water on the day of immunization. Clean the brooding house in time. 2 regular ventilation and ventilation. 3 Work clothes and utensils are cleaned daily and then sterilized with ultraviolet light for 2 hours. 4 regularly replace the entry and exit disinfection pool disinfectant. 5 The brooding house should be regularly sterilized with chicken sprays, and the surrounding environment should be regularly spray-disinfected, avoiding immunization time. 5. In addition, also pay attention to regularly weigh the chicks and make every record, timely grouping, to create a quiet and suitable growth environment for chicks.
