15 days before hatching
(1) Cleaning the chicken house: Firstly, the whole house can be spray-disinfected with the concentration of 1:400, and then the equipment and utensils can be moved out for cleaning and disinfecting to completely eliminate feces, litter, feathers, and dust in the house. Pay attention to the clean of the ceiling walls and doors and windows, raise the ground flatly, and dig up the soil and litter on the ground to make fertilizer. Replace it with new soil and press hard, preferably lime soil.
(2) Sweeping the surrounding environment of the chicken house: There should be no chicken droppings, feathers, garbage around the chicken house, and the excrement should be sent to a place several kilometers away from the chicken house for accumulation and fermentation as fertilizer, which cannot be stacked around the house.
(3) Disinfect the cleaned chicken house: The ground and the surrounding environment are disinfected with 3% fire alkali. The ceiling and the four-wall application can be used for disinfection. Lime is sprinkled throughout the site and on the off-site roads. In and out personnel should be strictly disinfected. .
(4) Move the clean appliances and equipment after disinfection and disinfection into the hen house to inspect and repair the heating, ventilation, lighting and other equipment.
9-7 days before entering
(1) Re-sterilize: Disinfect the entire house and equipment with spray disinfection with concentrated glutaraldehyde (or other disinfectants) and disinfect the entire house and equipment from top to bottom with 3% caustic soda on the ground and in the environment. (Alkaline corrosiveness is relatively large, use caution)
(2) Check for leaks: Check doors, windows, vents and ceilings to ensure that there are no dust left by the batch of chickens. After the ground is dry, it is moved into the litter.
5 to 4 days before entering
(1) Smoke disinfection: generally use 42ml formalin and 21g potassium permanganate per cubic meter of space, and put a smoke box every 10m, first put potassium permanganate, then pour in formaldehyde, Smoke disinfection must pay attention to safety. Immediately after leaving the doors and windows sealed, sealed for 24 hours. Or use Dongdong products: smoked Lijing: 200 cubic meters per bag.
(2) Ventilation of the chicken house door and window 24 hours after the tobacco is sterilized. In order to enter and exit the chicken house, it is convenient to sterilize. A disinfection pool should be set up at the entrance of the chicken house. The disinfectant should be changed once every two days to keep it effectively sterilized. concentration.
Three days before
We will implement all preparations for infants, including facilities, feed, medicines, and heating coal.
2 to 1 days before hatching
Preheating, warming, test temperature, the temperature should be higher than the brooding temperature of 2 °C or so, check whether the furnace is good to burn, the chicken house is heated evenly everywhere, there is no smoke leakage, one day before the advent of chicken, the temperature should reach Requirements, paved the bedding, ready for chicks and medicines, and set up a chicken fence.
Into the chicken 1-4 days old
(1) Drinking water: Fill the watering device with water at about 20°C for 2 hours before entering the baby. Add 5% dextrose in the water to electrolyze multidimensional food. For chicks that are transported in a long distance or have a long storage time, the amount of drinking water should be controlled. In order to prevent dehydration of the chicks, too many drinking water appears to be watery. At the age of 2 to 5 days, the drinking water will be multi-dimensionally electrolyzed and phosphorus rods will be cleared for four generations, or with Weikangling.
the purpose is to:
1 Reducing stress, catching young animals, and transporting the environment are all stressful for chicks.
2 to prevent diseases, some diseases are transmitted vertically from the breeder to the chicks, such as chickens, white feathers, slow call, E. coli disease.
3 Improve the health of chickens and promote the growth and development of chickens.
4 Now that there are many cases of adenocarcinoma of the abdomen, prevention must be done in advance so as to prevent the influence of the later period or prevent immunosuppression.
(2) Temperature: The temperature is stable at 35°C within 1 day of age and the temperature is stable at 35°C. After each day, the temperature drops by 0.5°C; the humidity is maintained at 65%--70%. If it is not reached, the temperature can be increased. An aluminum pan is added to the furnace to evaporate the water vapor, and the phenomenon of high temperature and low humidity is firmly avoided to prevent dehydration of the chicken. Attention should be paid to ventilation during the heat preservation.
(3) Feeding: When the chicks drink water, they will be fed with food, and the feed will be sprinkled on the pad paper or material box. It will not be added to the ground and will be withdrawn every 2 hours or so. The new material will be replaced with dirty materials. After 4 days of age, Feed 1 time every 3 hours.
(4) Illumination: 24-hour light for the first 2 days of age. A 40-watt light bulb for every 15 square meters, 23 hours of light from 3 days of age, 1 hour of darkness, and 12 hours of light turning off at night. (Sometimes depending on the situation)
(5) Note that after entering the chick:
1 carefully pick out the weak young, isolation and rearing, check whether the umbilical cord incomplete contraction, found that bulge, black pedicle, bloodshot and even odor of the chicken should be eliminated, due to grab the water wet chicken feathers should be pulled out, set In high temperature and dry place, there should be no reluctance.
2 Observe the flock carefully and control the temperature and humidity at any time. Find out if the flock is gathering or lying near the fire source. It means the temperature is too low and should be warmed. If the chicken is far away from the fire source, gather at the root of the wall, indicating the temperature Too high to prevent high temperatures and low humidity, dehydration of chickens.
3 at any time to eliminate the food in the open dish, make a daily record, such as the number of death, the amount of feed, the temperature of chicken coop in the morning and evening.
(6) Disinfection
After 13 days of age, the chickens were sterilized: one hundred poisons or four chickens could be sprayed to disinfect the chickens and disinfected within 5 meters. When disinfecting chickens, be careful not to direct the chick sprays.
2 Replace the disinfectant in the disinfection disc at the door to maintain the disinfectant concentration.
5-6 days old
(1) 5 days old shelve temperature adjusted to 33--34°C; 6 days old 32.5°C, humidity 60%--65%, light for 23 hours.
(2) Feeding a total of 8 times a day: 5 times during the day and 3 times at night (this method is difficult for most people). Each feed was fed before the age of 3 weeks, control for half an hour, limiting the chickens to eat, to prevent the occurrence of sudden death, can also prevent the occurrence of ascites. And within three days, they gradually changed into feed buckets and first withdrew a portion to allow the chicks to gradually adapt.
(3) Replace or increase litter, replace disinfectant in the door disinfection basin, and stop disinfecting the chicken, because 7 days of vaccination, so as not to affect the effect.
(4) To improve ventilation and ventilation, most of the natural ventilation we use is to ventilate the air from above to prevent cool air from blowing directly onto the chicks, so that the interiors are completely replaced with fresh air.
7 days old
(1) The temperature is controlled at 32°C, the humidity is 60%-65%, and the light is 23 hours a day.
(2) Vaccination (reference procedure) Inoculate the eyes with Newcastle disease secondary seedlings and intramuscularly inject new tributaries or new flow glands. Precautions:
1, the preparation of vaccine water can not contain chlorine and other disinfectants, and before and after 2 days with chicken or drinking water disinfection. Do not use containers containing iron for vaccination.
2, with a good vaccine can not be sun light.
3, nasal drops should be disinfectant disinfectants, the application of high-temperature disinfection, when the catcher should be light, so that the vaccine is completely inhaled into the nose or eyes before placing the chicken.
4, before and after the vaccination, can not use antiviral drugs, chloramphenicol, sulfonamides, furazolidone and other drugs before and after two days, so as not to affect the immune effect. One of these drugs is banned and two will cause immunosuppression.
5. Observe at night whether there is a vaccine response in the flock. If the reaction is serious, immediate remedial measures should be taken.
8-14 days old
(1) The 8-day-old temperature is controlled at 31.5°C, (sometimes according to the situation, 0.5 degrees can be divided into two drops), and the daily drop of 0.5°C, humidity 60%-65%, and light control for 23 hours.
(2) Drug drinking water Add enteritis drugs, coccidiosis drugs to prevent necrotic enteritis, intestinal coccidiosis drugs, or mix with no regrets to prevent enteritis coccidiosis, observe whether the chickens have vaccine reactions, respiratory symptoms, such as Electrolysis can be added in drinking water multidimensional, and add mycoplasma drugs, such as: doxycycline, Hushuang, lung Yuqing to reduce the reaction and treatment of respiratory diseases.
(3) When the breeding density is large, expand the group, add drinking water to the electrolysis multidimensional when expanding the group, timely weigh and make records, replace the drinking water with deep well water or tap water, feed the chicken completely with the material bucket, and the water dispenser is generally water Line, adjust the edge of the drum, with the chicken back height, adjust at any time later.
(4) Feed 8 times daily, 5 times during the day, 3 times at night, (less likely) and feed once.
(5) Ten-day-old offspring were inoculated with fowlpox, and they took 2 heads of stings on the wings.
15-19 days old
(1) The 15-day-old temperature is maintained at 28--29°C. After that, the humidity is kept at 0.5°C every day for 60%-65%, and the light still remains for 23 hours.
(2) This stage is prone to respiratory diseases and the occurrence of large rods, so this time the medication is also very critical, drinking water, phosphorus rod Qing seven generations, doxycycline or lung Yuqing to control the large rod and respiratory tract, improve body resistance ability.
(3) From the age of 15 days, it was changed to feeding system for 4 or 2 feeding, that is, feeding 4 times during the day and feeding 2 times at night. Mix 1/5 of the prepared medium chicken feed with the chick feed 4/5 at 17 days of age and then feed 1/5 of the chicken feed daily until it is completely replaced with medium chicken feed. Reduce the stress on refueling chickens by gradually transitioning.
(4) Pay attention to whether there is a vaccine response or changes in faeces. If there is a need to increase the amount of drug to the amount of drug treatment, if properly applied, symptoms can disappear within 2 days.
(5) Strengthen the management of environmental sanitation, clean up the excrement in time and replace or increase the litter. After 16 days of age, the chickens can be sprayed and disinfected with Wei, and the ground within 5 meters around the house is sterilized once every 1-2 days. Increased ventilation reduces the concentration of ammonia and hydrogen sulfide gas in the home. Peracetic acid spray or evaporating vinegar on the stove can be used to reduce the ammonia concentration in the chamber.
(6) Influenza H50.3 ml per chicken at the age of 18 to 19 days was injected intramuscularly and 2 H120 eyes were spotted. Influenza and transmission were observed in the later period.
21-25 days old
(1) The 21-day-old temperature is controlled at 25--26°C, after which the daily drop of 0.5°C, humidity 60%-65%, and the illumination should be adjusted to 22 hours.
(2) The addition of terminator and balloon dilation to the drinking water of 21 or 24 days of age prevents the occurrence of viral diseases and airsacculitis. Garlic and probiotics can also be added to feed to aid digestion. Adjust the balance of intestinal flora to promote growth. Observe feed intake, mental status and fecal abnormalities at any time. Some individuals do not eat, lack of energy, anal sticky green, white feces and other chickens into the isolation barrier in time, you can use injections Qingda and Qingkailing intramuscular injection. If you pull blood, you can feed Dahongpao.
(3) From the 21st day of age, all of the chickens were converted into medium-sized chickens, fed on a four-by-two basis, and the daily feeding amount and the number of dead fish were recorded.
(4) Weigh the birds and analyze the growth status of the flock.
(5) Do not disinfect with 100% poison or Wei disinfectant etc. at the time of not taking the vaccine, and 2% fire alkali can be used for disinfection. After 21 days of age, drinking water must not be accompanied by disinfectants and can not be sterilized with chickens so as not to affect the 23-day-old Newcastle disease immunity.
(6) Strengthen ventilation and reduce the concentration of harmful gases such as ammonia gas and hydrogen sulfide in the house.
25--28 days of immunization, a new flow of 0.4 ml per chicken, 2 doses of larynx acne vaccination.
28-32 days old
(1) The 28-day-old temperature is kept at 23--24°C, humidity 60%-65%, light for 22 hours, and the temperature is kept at 21°C from the 29th day of age, and the minimum is not lower than 18°C.
(2) This stage is the stage of E. coli disease, and because the vaccine has just finished drinking, it can easily cause chronic respiratory disease. Observe whether there are respiratory symptoms and fecal abnormalities.
(3) Change or add litter once every 2-3 days to strengthen litter management and clean the environment. Disinfect chickens with sterilizer once every 2-3 days and clean and sterilize the surrounding environment. Pay attention to the handling of dead chickens. Do not leave the chickens everywhere. You should go deep to the ground and replace the disinfectant in the door disinfection pot.
(4) Management is mainly based on ventilation.
(5) Use no regrets
35-39 days old
Inject 0.5 ml each of H5 oil seedlings and use 3 times the amount of Newcastle disease.
(1) The temperature is maintained at 18°C ​​to 21°C, the humidity is 60% to 65%, and the light is irradiated for 22 hours.
(2) In the drinking water, add new Shuanghe phosphorus rods to clear the fourth generation and sweep the yellow to prevent large rods and viruses. The anti-virus can remove the exudates caused by inflammation, especially the chickens with ascites symptoms, and use them for 3-4 days. Can also be expected to add garlic or probiotics to improve feed conversion.
(4) Pay attention to the temperature difference, control the temperature, ensure that the air in the house is fresh, and reduce the ammonia smell.
(5) timely replacement of litter to enhance ground health.
(6) Weigh regularly to analyze the management level.
40-49 days old
