The daily management level of chicks is related to the chick breeding rate and the production efficiency of the farm. In winter, the climate is cold, the environmental conditions are poor, and the immunity of the chicks is low. In the winter, the chicks should be strengthened daily management, pay attention to keeping warm, strengthening immunity, scientific feeding, raising chicks The breeding rate increases the economic efficiency of raising chickens. Therefore, this issue introduces a group of routine management techniques for winter chicks for reference by farmers.
Aquaculture facilities
The furnace is generally heated in a broiler, but a chimney must be installed to prevent gas poisoning. The chimney can be properly extended according to the situation to facilitate sufficient heat dissipation and energy saving. Illumination time has a great influence on the growth rate of chickens. In addition to daily natural lighting, artificial lighting equipment is also required. Therefore, two lighting lines are to be installed in the chicken house. One lamp cap is installed every 3 meters, and one bulb lamp is used for every 20 square meters. The height is 2 meters from the ground, and incandescent lighting is generally used. Equipped with the necessary cleaning and disinfection equipment, such as high pressure cleaners and disinfection sprayers.
The grid should be sturdy and durable. The net bed should be smooth and flat. The length depends on the length of the chicken house. Each lane is 0.9 meters high and 3.5 meters wide. A 0.4 meter high fence should be provided. It is not necessary to use the entire net bed at the chick stage. The whole net bed can be separated into several individual chicken houses using plastic sheeting. Only part of the net bed is used, and the area is gradually expanded as chicks grow to meet the density requirement. Drinking water and feeding equipment should be sufficient to ensure that the chicks drink water and feed. The general brooding stage requires every 50 chicks to be equipped with a drinker and feeder, one for every 30 days after 20 days of age.
Into the preparation
12 to 15 days before hatching, clean the excrement of the chicken house, clean the water fountain and feeder, rinse the wall, roof, net bed, and ground of the house with a high pressure water gun, and check and repair the equipment of the chicken house; 9 to 11 days before the hatching The first time the chicken house was sterilized, including nets, floors, drinking fountains, feeders, etc. The doors, windows and vents should be closed during disinfection. After 10 hours, the windows should be opened for ventilation. The doors and windows should be closed after 3 to 4 hours of ventilation. At the same time, the drinking fountain and feeder are soaked and sterilized with a disinfecting solution; the second disinfection is performed 4 to 6 days before the chickling. The solution can be disinfected with 40% formaldehyde solution 300 times the liquid, and the temperature is checked before sterilization to make the temperature of the chicken house reach 26 Above °C, the humidity is over 80%. The disinfection should be thorough, leaving no dead ends. Close the doors and windows for more than 36 hours after disinfection. Then open the ventilation for not less than 24 hours. Prepare the feed 1 to 3 days before the hatchlings, and use a plastic cloth to cover the net. Beds are well separated and separated by 30 to 40 stocking densities per square meter in the first week of the brooding period. Preheating (preheating of walls and floors), pre-wetting, winter preheating should be carried out 3 days before hatching, and preheating temperature should be above 35°C. At the same time, a layer of cardboard is laid on the net bed to prevent the chicks from getting cold, and after the pre-heating and pre-wetting are completed, the chicks can be introduced into the chicks.
Disease prevention and control
Adhere to the principle of "prevention as the main, treatment as the supplement, and prevention as emphasis on treatment". In particular, serious infectious diseases caused by some viruses should be vaccinated on a regular basis. One-day-old, Marek's disease attenuated seedlings were injected subcutaneously; 7-day-old Newcastle disease clone 30 or IV seedlings were given intranasally, and 0.25 ml of Newcastle disease oil emulsion-inactivated vaccine was injected; 10-day-old infectious bronchitis and renal transmission Two-stage seedlings drinking water; 14-day-old bursal disease multivalent vaccine drinking water; 21 days old, chicken pox seedlings; 24 days old, bursal vaccine water; 30 days old, Newcastle disease IV line or clone 30 two exempt; 35 Day-old, infectious bronchitis, renal transmission 2 free. The above immunization procedures are not fixed, and farmers can increase or decrease certain immunity according to the prevalence of local epidemics.
Prevention of drug use during the prevention and treatment of chicken diseases is an indispensable component. Chickens less than 14 days of age are mainly used for the control of chicken fleas. 0.2% of furazolidone, or chloramphenicol, enrofloxacin, etc., can be added to the feed. After 15 days of age, it focuses on the prevention of coccidiosis, which can be used alternately with Amprolium, Diclazuril, and Clopidol. If there is a serious outbreak in the local area, drug prevention should also be carried out. Virus infections and some anti-virus herbal medicines may be used for viral infections, but at the same time, antibiotics must be used to prevent secondary infections.
Brooding Management
The first stage
1 to 2 days old chicks should be sent to the chicken house as soon as possible. Do not place them on the net bed immediately after entering the house. Use 1st inactivated vaccine against Newcastle disease bronchitis to immunize the right eye of each chick with 1 drop. Placed on a net bed. After the immunization was completed, the chicks were given water for the first time. The chicks needed to use warm water of about 20°C in the first week of drinking water, and added various vitamins to the water. The amount of water was sufficient to ensure that each chick was allowed to drink water.
The chicks started eating for the first time. Before eating, they drank once with 40,000 international units of potassium permanganate solution to disinfect and excrete meconium and clean up the intestinal tract. After 3 hours of drinking water for the first time, the feed can be fed. The feed uses chicken-specific materials. At the beginning, it is fed 5 to 6 times a day. For weaker chickens, it is fed once at night and gradually changed to 3 to 4 times a day. The amount of material used for chicks should be based on actual feeding conditions. Feeding must be done regularly, quantitatively, qualitatively, and clean drinking water must be maintained. Chick nutrient index of crude protein 18% to 19%, energy 2900 kcal per kilogram, crude fiber 3% to 5%, crude fat 2.5%, calcium 1% to 1.1%, phosphorus 0.45%, methionine 0.45%, Lysine Acid 1.05%. Feed formulation: (1) 55.3% corn, 38% soybean meal, 1.4% dicalcium phosphate, 1% rock powder, 0.3% salt, 3% oil, 1% additive; (2) 54.2% corn, 34% soybean meal, vegetable meal 5 %, calcium hydrogen phosphate 1.5%, stone powder 1%, salt 0.3%, oil 3%, additive 1%; (3) corn 55.2%, soybean meal 32%, fish meal 2%, vegetable 4%, calcium hydrogen phosphate 1.5%, Stone powder 1%, salt 0.3%, oil 3%, additive 1%. From 11 grams per day per day to 52 days per day, each about 248 grams per day, an increase of about 4 to 6 grams per day, feeding on time every day, according to the number of chickens, the growth rate determines the number of days.
Broilers are allowed to feed freely within 1 to 7 days of the brood. The first day requires feeding once every 2 hours. Attention should be paid to feeding and diligent feeding. Observe changes in temperature and chick activity at any time, such as uniform distribution. Appropriate temperature, such as stacking shows that the temperature is too low. Ventilation during brooding period should not be too large, but ventilation should be strengthened when the gas and disinfection are too strong. Ventilation can be performed at high temperatures outside the house at noon every day. In the 1-2 day brooding, the temperature should be kept above 33°C and the relative humidity is 70%. For the first 2 days, 24 hours light should be used and the 40W incandescent light bulb should be used for illumination.
From 3rd to 4th day old chicks, the temperature in the house was reduced to 32°C from the third day, and the relative humidity was kept between 65% and 70%. During the period, the chicken manure should be observed and the dung should be replaced to replace the pad, paying attention to the coal stove. Chimneys and venting conditions to prevent gas poisoning require that the material be fed every 3 hours, and on the 3rd day, reduce the light for 1 hour and keep the light for 23 hours.
Chickens were immunized at 5 days of age and Newcastle oil seedlings were injected subcutaneously in the neck. From the fifth day, the temperature in the house was adjusted to 30°C-32°C, the relative humidity was kept at 65%, and the feed plate was changed to the chicken tray at the 6th day of feeding. The replacement of 1/3 starter plate was performed every day. Feed 6 times a day, turn off the lights for 2 hours in the evening and keep the light for 22 hours. From the 7th day, the area of ​​net beds was expanded to maintain the chicks' density at 35 per square meter.
second stage
On the 8th to 14th day of the chicks, the temperature of the house was reduced to 29°C from the 8th day. On the 9th day, a variety of vitamins were added to the chicks' drinking water to immunize the chickens. Newcastle disease TV seedlings were used for eye drops or nasal drops. 1 drop of chicken. At the same time, on the 9th day, replace the water dispenser, remove the chick waterer and replace it with a chicken drinker, and adjust the drinker to an appropriate height. During this period, attention should be paid to observation of temperature, humidity, and proper ventilation, especially at night when there should be no abnormal breathing sounds. From the 8th day onwards, regular dosing should be performed. The amount of feed to be fed should be controlled flexibly according to the weight of the chicken. Generally, no restrictions are imposed on the amount of feed. There will be no remaining food, 4 to 6 times a day, and on the 13th to 14th days. A variety of vitamins were added to drinking water, and chickens were immunized on the 14th day. After the immunization, drinkers should be cleaned and multivitamins added to drinking water. At this time, the area of ​​the net bed is gradually expanded as the chicken grows, and the temperature of the house is maintained at 28°C and the humidity is 55% during the period.
The third phase
The 15th to 22nd day old chicks continued to drink Vitamin water for one day on the 15th day, and the ventilation was enhanced. On the 17th to the 18th days, 0.2% liquid peracetic acid was used to disinfect the chickens. On the 19th day, the chickens were replaced with the feeds for chickens. Do not replace them all at one time. Replace them in 4 days, ie use 1/day. 40% of the chicken material was replaced with chicken material and mixed until they were all replaced with chicken material on the 4th day. During this period, the house temperature should be gradually reduced from 28°C on the 15th day to 26°C on the 22nd day, 1°C on 2 days, and the humidity should be controlled at 50%-55%. At the same time, as the growth rate of chickens expands the area of ​​the net bed, the stocking density is kept at 10 per square meter, and the height of the drinker is adjusted to meet the growing needs of chickens. At 22 days of age, chickens were immunized with Newcastle disease using four lines. The light was kept at 22 hours. After 15 days of age, the lights were switched from 40 watts to 15 watts for illumination.
23 to 26 days old chicks should pay attention to the control of temperature and humidity after immunization. After 25 days of age, chickens should be disinfected once and super strong multidimensional water should be added to the drinking water. When the temperature is 26 days, the temperature inside the house should be reduced to 25°C. Control at 45% to 50%.
27-34-day-old chicks should be strengthened daily management to be often ventilated, such as the temperature in the chicken house is too high, to use cooling curtains and exhaust fans for cooling. During this period, the room temperature should be lowered from 25°C to 23°C and the humidity should be maintained at 40% to 45%.
From 35 days old to slaughter, chickens are forbidden to use any medicines when they grow to 35 days of age. They must increase ventilation and ventilation in the house. The temperature of the house should be reduced to 22°C from the age of 36 days. From the 35th day of age to slaughter, 24 hours of light should be maintained every day to increase the feed intake of chickens. The chickens were sterilized once at 37 days old. The temperature of the chicken house was lowered to 21°C and maintained until slaughter at 40 days. At the age of 43 days, the chickens were sterilized for the last time. They were generally slaughtered at 45-52 days and weighed about 2.5-3. kg.
