Chai chicken, also called stupid chicken, has the characteristics of tolerance to rough feeding, strong nesting ability and strong disease resistance, and its meat is delicious. Wood-fired eggs are very popular in urban and rural markets, and the egg price is higher than ordinary eggs. For farmers with certain conditions, the cost of raising chickens is relatively low, making them suitable for family breeding. The complete set of techniques for raising chickens is now introduced as follows:

1. Feeding and management during the brooding period 1. Thoroughly disinfect the chick house before entering the chicks. All equipment in the house must be inspected and repaired. Before entering the chicken house, the temperature of the chicken house should be raised to 33°C, and the relative humidity should not be less than 60%. The lighting is set as 23 hours of light and 1 hour of darkness. Keep the water fountain in a bright place so that the chicks can find it easily.

2. When picking up chicks, choose chicks that are healthy and lively, have strong struggles, crisp calls, good umbilicus collection, clean feathers, and good uniformity. After the chicks are connected to the chicken house, drinking water (not lower than 35°C) and feed should be provided as soon as possible to ensure that each chick can drink water and eat food normally. Manual help can be provided for chicks that do not drink water. It is prohibited to clean the floor within 15 days after the chicks enter the house.

2. Feeding and management during the breeding period 1. Construction of the stocking site ① After the fenced stocking site is determined, a nylon net should be selected to form a closed fence with a height of 1.5 meters, and the chickens can eat freely in the fence. The area of ??the fence depends on the number of chickens. Generally, each chicken occupies an average of 8 square meters.

② The chicken coop should be built in a high, dry, well-drained place, more than 500 meters away from the road. The chicken coop can also be built in the woods or on the edge of the woodland, facing north and south.

The chicken house can be a plastic greenhouse type, 6 meters wide, and the length is determined according to the number of chickens. The inner layer of the roof of the greenhouse is covered with non-drip film, and a layer of straw is laid on top for thermal insulation. Cover with plastic film and secure with rope. The lower edges on both sides of the longitudinal axis of the plastic greenhouse can be rolled up or put down to adjust indoor temperature and ventilation. The ground in the shed can be padded with fine sand to make the room dry. 6 to 8 chickens can be raised per square meter. At the same time, a multi-layer egg-laying nest and perch should be built. The size of the egg-laying nest should be suitable for 2 chickens.

2. Key points of feeding and management The breeding period refers to the period (31 to 240 days old) after the chicks are de-warmed to the stage when the hens start to give birth and the roosters are put on the market. It is a critical period for the growth and development of chickens. Pay attention to the following Key points of feeding and management techniques.

① During the stocking season, try to arrange for the chicks to be de-warmed and start stocking when the daytime temperature is not lower than 10℃. ② Free-range training and training. In order to make the chickens return to the shed on time for feeding, when the de-warmed chickens are released in the morning and evening, they can be tamed and trained regularly by knocking on the basin or blowing a whistle.

It is best to cooperate with two people. One person blows the whistle in front to clear the way and throws the feed, so that the chickens can follow and grab it; the other person drives them behind with a bamboo pole until they all enter the feeding area. In order to enhance the effect, in the first few days, set up a feeding trough and water tank in the stocking area at noon every day, add a small amount of full-price feed and clean water, blow the whistle and induce food once. At the same time, breeders should promptly get rid of chickens that return early. In the evening, use the same method for home training. After repeated training for several days, the chickens will be able to establish conditioned reflexes.

③ Provide sufficient drinking water and place some drinking utensils within the range of chicken activity, such as 1 porcelain basin of water for every 50 chickens. Also avoid letting chickens drink unclean water.

④ Regular and quantitative supplementary feeding should be fixed and cannot be changed at will.

You can supplement less in summer and autumn, and more in spring and winter; when 30 to 60 days old, supplement about 25 grams of concentrate daily, once or twice a day. The reference formula is: 61% corn, 15% soybean meal, 6% peanut cake, 7% bran, 5% fine bran, 3% fish meal, 1.7% bone meal, 1% vegetable oil, and 0.3% salt. After 8 weeks of age, in order to increase the energy concentration and feeding amount of the feed, it is also necessary to increase the fat, but do not add fats with strong smell such as butter and mutton fat. The amount of fat added is 3% to 5%. Daily supplement amount of essence: 30 to 35 grams for 3 to 4 months old, 40 to 45 grams for 5 to 6 months old, 50 to 55 grams for 7 to 8 months old, 2 times a day, 1 gram each in the morning and evening. Second-rate.

⑤ The fermented worms are fermented in the pasture by using pig and chicken manure that has been sterilized and fermented, add 20% loam and 3% bran, mix well and pile it into a pile, then cover it with film and ferment for 7 days. Around 20 days, spread the fermentation material on the brick floor, cover it with grass, and keep it moist for about 20 days to breed insects. Sprinkle part of the fermentation material every day for chickens to eat, which can save 30% of feed.

⑥Supplementary light Natural light is short in winter and spring, so artificial supplementary light must be implemented. It is appropriate to use 5 watts per square meter, from evening to 10 pm, and from 6 am to dawn. Do not supplement the light suddenly for a long time. Increase the light for half an hour every day and gradually transition to 10 pm. If natural sunlight exceeds 11 hours a day, supplementary light is not required. After the lights are turned off at night, there should be some lights with low light to illuminate the chickens all night long so that the chickens can walk and drink water. In the summer when there are many insects, you can hang some purple or incandescent lamps in the habitat.

⑦To prevent animal damage and pesticide damage, measures should be taken to prevent weasels, eagles and other natural enemies from catching chickens. If chickens are raised in an orchard, biological pesticides must be used when spraying pesticides. < /p>

⑨ Carefully manage the cultivation period and achieve "five diligences".

First, observe the chickens frequently. Healthy chickens always rush to fly out, while sick and weak chickens move slowly or are unwilling to leave the house. The second is to observe frequently when cleaning. When cleaning the chicken house and removing manure, observe whether the feces are normal. The third is to observe frequently when replenishing materials. Observe the mental state of the chickens frequently when feeding. Healthy chickens often appear impatient, while sick and weak chickens do not eat or are slow to respond. Fourth, observe your breathing frequently. After turning off the lights at night, listen to the chicken's breathing to see if it is normal. If there is a "gurgling" sound, it means there is a respiratory disease. The fifth is to observe frequently when eating. From stocking to before birth, feed intake gradually increases and becomes normal. If sick chickens are found, they should be treated and isolated in time.

3. Feeding and management during the laying period: Hens start laying when their weight reaches 1.3 kg to 1.5 kg. The male to female ratio of commercial laying hens is 1:25. Feeding management is to allow chickens to eat freely in the stocking area during the day, and supplementary feeding once in the morning and evening. The daily supplementary feeding amount is 50g to 55g. This should be done throughout the laying period (241 to 600 days of age). to the following points.

1. The nutritional concentration of the feed during the laying period should be mainly concentrated feed, with appropriate supplementary feeding of green and juicy feed. The nutritional concentration of the concentrate should be 15% to 16% in crude protein and 3.5% in calcium. , phosphorus is 0.33%, and table salt is 0.37%. It is necessary to strengthen the management of the transition period of chickens. There must be a transition period from the breeding period to the laying period. When the egg production rate is 5%, start feeding laying hens. Generally, the transition period is 6 days. In the concentrate Change 1/3 every 2 days, and finally turn it into layer feed.

2. To increase the light time, it is generally implemented to supplement the light twice in the morning and evening. In the morning, it is fixed from 6 o'clock to dawn, and from 6:30 to 10 o'clock in the evening. The whole day light is more than 16 hours, and egg production is After 2 to 3 months, adjust the daily lighting time to 17 hours. The supplementary light starts at 5 o'clock in the morning and remains unchanged in the evening. Feed the supplementary light at the same time. Once the supplementary light is fixed, do not change it easily.

3. Check the egg weight during the early stages of laying.

After 2 months of laying eggs, the egg weight basically reaches the normal standard. On average, 24 eggs weigh 1 kilogram. Insufficient nutrition will affect the weight of the eggs. Second, look at the egg shape. The egg shape is perfect. If the large end of the egg is too small, it means it is not eaten early and enough concentrate should be added. Third, look at the rising trend of egg production rate. The egg production rate will reach about 60% after 3 months at the latest; if the egg production rate fluctuates greatly, the reason should be found in the feeding and management. Fourth, check the weight of the chicken. After laying eggs for a period of time, if the weight of the chicken remains unchanged, it means proper management; if the chicken is too fat or too thin, the feeding amount should be adjusted. Five, look at appetite. When feeding chickens, if the chickens quickly gather around and compete for food, you can feed them more; if they come slowly and do not gather together to compete for food, you should feed them less.

4. Prevent hens from nesting in a dark environment and not removing eggs from the nest, which can induce nesting in hens. Therefore, the number of egg picking times should be increased to ensure that eggs are not left in the laying nest on that day. Stay overnight. Once a nesting chicken is discovered, the environment should be changed in time, placed in a cool and bright place, and fed more green and juicy feed. The chicken will leave the nest quickly.

5. Strict epidemic prevention and disinfection. Chickens grown in a free-range environment are easily affected by external diseases, so epidemic prevention and disinfection must be in place. First, it is necessary to strictly follow the chicken epidemic prevention procedures under the guidance of veterinarians. Second, we must do a good job in sanitation and disinfection. Disinfection belts or disinfection pools are provided at the entrance and exit of the stocking farm, and visitors are prohibited. Third, we must achieve "all in, all out". After each batch of chickens is released, the chicken shed should be thoroughly cleaned and disinfected, and all utensils, basins, etc. should be fumigated before adding the next batch of chickens.

6. Pay attention to the bad weather or bad weather. The chickens should be driven back to the shed in time for feeding. Do not go up the mountain to stock them to avoid losses caused by death and injury.
