The quality of brooding is not only directly related to the survival rate of the chicks, but also has a great influence on the production performance in the later period, and it also affects the cost of each chicken, directly affecting the economic benefits of keeping chickens. Generally 0 to 6 weeks old is the brooding stage, which is the key moment of the chicken production cycle. The chicks are short-thick and weak in cold resistance; the hernia sac and myogastric capacity are small; the digestive function is weak; the gallbladder is easily frightened and the disease resistance is weak; the neuromodulation function is not perfect, and the ability to adapt to the environment is weak. Therefore, according to the physiological characteristics of the chicks, to create a good and appropriate environmental conditions in order to achieve a satisfactory brooding effect. In general, raising a good chick must grasp the following key elements. 1 Prepare for brooding The preparatory work before brooding mainly refers to the preparation of brooding houses, feeding tools, brood feed, epidemic prevention and vaccine drugs. 1.1 The brooding bred larvae are to be ready in the first half of the month before hatching, cleaned up, repaired fissures, blocked rat holes, wiped windows and doors, sterilized the walls with 10% lime milk, and renewed the soil on the ground. Padding grass, hot alkaline water or 1% fire alkali water disinfection. Farmers advocate fire pit brooding or laying ground hot-line brooding, and they are qualified to purchase infrared electric brooders or electric heat preservation umbrellas. If the brooding house is newly built, it must be used dry and urgently fired and dried. 1.2 The equipment for brooding, such as troughs, sinks, and sweeping appliances, must be complete, washed and dried. Before closing the chicks, hang up the curtains, cover the grass, and warm the fire (warm stoves) to warm them up. The brooding utensils are sprayed with 3% of the Suer or 2% of the fire alkali water. 1.3 Sterilization of brooding houses Before entering the young brooding house to clean and disinfect. The method was sprayed with 2.0% fire alkali water or 20% lime milk and then fumigated with formaldehyde. Fumigation method: potassium permanganate 7g, formaldehyde 14mL and 7mL mixed water fumigation, fumigation under closed conditions for more than 12h, open the doors and windows for ventilation. In front of the brooding room, there must be a lime pool or a fire-alkali water disinfection pool. 1.4 Preparation of brood feed and medicines In order to increase the survival rate, the feed for chicks requires a full-price compound feed, and the feed quality is better, and self-provisioning and purchase can be used. Commonly used chick feed ingredients are corn, bean cake, bran, fish meal, bone meal, vitamins, trace elements, salt, methionine, lysine and so on. Prepare commonly used vaccines and drugs, such as: Marek vaccine, Newcastle disease II and H120, laryngotracheitis vaccine, bursa vaccine. Disinfectant drugs such as fire alkali, formaldehyde, potassium permanganate, etc. as well as milk enzyme, green streptomycin, furazolidone, and enemy bacteria net. 2 Choosing a good chick Choosing healthy chicks is the basis for raising the survival rate. The criteria for selecting chicks are as follows: The chicks should be selected for healthy and disease-free breeding farms; the chicks should be full-fledged, medium in length, lively and agile; the mouth and legs should be thick and shiny; Great God, lively and robust; abdominal soft and deep, full umbilical healing, no blood marks at the umbilical cord; clean around the anus, butt is not big; powerful legs, can stand and walk, do not swing around, feel strong in their hands; moderate body shape No abnormalities, crisp sound; all out of breeders must be injected with Marek's vaccine within 24 hours after hatching. 3 Delivery of chicks For chicks to be picked up, it is best to prepare the equipment for picking up the chicks. It is best to use special equipment for the farmer to transport them away. The farmers can dig a few holes in the cardboard box (short grass on the bottom), pay attention to ventilation, and the density should not be too large, nor should they be too thin. On the way, as smooth as possible, pay attention to insulation, cold, sunscreen, anti-leaching, etc., and move to a brooding place after arriving home. 4 Select the brooding method according to the conditions Brooding methods are divided into planar brooding and standing sports. 4.1 Plan Brooding Brooding is called flat brooding on brooded ground or metal mesh. Ground litter brooding, fire pit brooding, shelf brooding, metal net brooding, brooding brooding brooding and so on. 4.2 Sports chicks are brooder brooders. Modern chickens often use this method. Four-layer cage electric brooders are commonly used for brooding. 5 Feeding The first hatching of chicks to be properly hatched is called eating, and the opening of food is carried out 24 to 36 hours after hatching. When eating, the feed should be fresh, the grains should be moderate, nutrient-rich and easy to digest. One of the commonly used feeds is soft boiled glutinous rice with egg yolk and antibiotics (norfloxacin, chloramphenicol); the other is fed with full-priced chicken feed. Pay attention to vitamin supplements, generally use cod liver oil, pure yeast powder as well, not only low prices, but also nutritional supplements to help digestion. 6 Drink plenty of water The first time the chicks drink water is the first drink. Early drinking can be done before eating or eating. Drinking water is best to drink warm water, you must first feed sugar water (concentration 5%), later let it drink, continue all day, do not drink cold water within 2 weeks, water temperature and room temperature can be similar. To prevent diarrhea, add 0.02% furazolidone in water. 7 The temperature should be moderate Proper temperature is the key to the success or failure of brooding. The ideal temperature is 30 to 33°C from 0 to 1 week of age. The brooding period can be reduced by 3°C per week, and it is reduced to about 20°C after 6 weeks. The control of the brooding temperature must be steady, remembering that the height of the temperature changes greatly and the chickens are infected with infectious diseases. The method of visually observing the temperature is: the chicks huddled together and even squeaked, screaming, indicating that the temperature was low; if the chicken was far away from the heat, the wings were open and the mouth was breathing, indicating that the temperature was too high. If the distribution is even and no call is heard, it means that the temperature is moderate. The principle of grasping the temperature is: early should be high, late should be low; small groups should be high, large groups should be low; weak young should be high, strong young should be low; rainy days should be high, the eye should be low; night should be high, during the day should be low The broiler should be high and the layer should be low. 8 Humidity should be appropriate In general, the relative humidity requirements of chickens are not as stringent as the temperature. The appropriate relative humidity for the brooding house is: 60% to 70% for 1 to 10 days and 50% to 60% for 10 days. Humidity is too high, chicks are prone to caries, coccidiosis, and aspergillosis; humidity is too low, chicks are prone to dehydration, and growth is slow. The brooding house in the early brooding season has a high temperature and a relatively dry environment. Therefore, if the humidity is properly increased, the water should be properly sprinkled, the water basin should be wetted, or the water tray should be placed on the stove to evaporate water vapor, which is beneficial to the development of the chicks. As the chicks grow up in the later brooding period, the amount of respiration and defecation increase, and the interior is prone to dampness. Therefore, when the relative humidity is high, ventilation and ventilation should be taken care of, and the dunnage should be replaced in time and the chick density should be appropriately adjusted. 9 Reasonable breeding density Feeding density directly affects the growth and development of chicks and the utilization of brooding facilities. The density is too high, the flock is crowded, the food is not uniform, the chicks are slow growing, the growth is irregular, the disease is susceptible to infection and spasm, and the death is increased. The density is too small and the premises and equipment cannot be fully utilized, resulting in waste. The correct chick breeding density is the number of chickens raised per square meter: 40 on the 1st to 15th day, 30 on the 16th to 30th day, 15 on the 31st to 45th day, and 10 on the 46th to the 60th day. 10 Correct lighting Light has an important relationship with the chick's intake, drinking, exercise, and health. In order to ensure the growth and development of the chicks and their subsequent production performance, chicks should be bred to develop normal lighting procedures. 0 to 3 days of age should be supplemented with day and night light, 4 to 7 days of light for 19 to 20 hours, 8 to 20 days of light for 15 to 19 hours, after 20 days of age can not add light, daily lighting time should be controlled at 8 ~ 10h. It is advisable to install a 40W light bulb with 15m2 of light intensity 1.5m above the ground. The light intensity should be strong in the early stage and weak in the later stage. The early stage can promote the feeding, drinking, and exercise of the chicks. 11 Pay attention to ventilation Chickens have higher body temperatures, quicker breathing, and greater metabolic function than other livestock. The body weight of carbon dioxide emitted by a unit of weight is more than twice that of large livestock. In addition, due to the high temperature of the brooding room, decomposition of feces and litter generates a large amount of harmful gases of ammonia and hydrogen sulfide. If no attention is paid to ventilation, the health of the chicks will be seriously affected, resulting in death. Therefore, under the premise of heat preservation, it is necessary to do a good job of ventilation and ventilation, eliminate indoor foul gas, and exchange fresh air. The degree of indoor air freshness is such that it does not feel stifling, pungent, and smelling of ammonia and hydrogen sulfide in the brooding room. In general, the brooding room should be provided with a special ventilation hole or a louver. If necessary, open the windows to allow fresh air for a while, but be careful not to let the outside wind blow the chicks directly to prevent the chickens from catching colds. 12 Environmental Health Management Chicks have a small body, poor disease resistance, and are kept intensively. Once they are infected with chicken disease, they are easy to spread and difficult to control. Therefore, it is necessary to implement the principle of prevention as the mainstay. Prior to the start of brooding, a strict disinfection and epidemic prevention system should be set up and implemented conscientiously. In order for the chicken to grow up healthily, in addition to the specific precautions, doing a good job in environmental hygiene is the key to chick health. The indoor environment should be cleaned regularly, kept dry, well ventilated, remove the excrement in time, replace the bedding, reduce noise, forbidden to startle, and outsiders are not allowed to enter the brooding room at will. Disinfect once every 10 days or half a month, do not feed the rancidity of spoilage fermentation. Feed to reduce the incidence of gastrointestinal disorders. 13 Group Management Chicks should be grouped according to their mother, mother, size, and strength so as to avoid uneven feeding and strong bullying. If conditions are limited and management cannot be divided into groups, small and young animals should be singled out and raised separately. The brooding can be divided into several plots for easy management. The general peasant households can only have one 50 plots, and the group should be smaller as the age increases. 14 Disruption Management Deterrence is one of the effective measures to prevent chicks from licking. After a chick has reached 2 weeks of age, it often causes spasms because of various reasons, namely, feathers, toes, and scrofula. In severe cases, there are casualties every day and the loss is large. The first solution is to strengthen the management of feeding, to create a suitable living environment for the chicks, full price nutrition; second is to use the method of cutting off. Chicks can grow for the first time after 6 to 9 days of age. The method is to insert the chick quail into the electrothermal stoma device and remove from the nostrils to the upper two-thirds of the upper jaw. The chin is less cut than the upper jaw and forms a certain slope. If there is no electric heating device, electric iron can also be used instead. 15 Disease Prevention and Control According to the immunization program, the vaccination work should be well done; to give drug control, garlic granules should be added to the feed within 2 weeks of age, and furazolidone, antibiotics or other drugs should be added to drinking water.
