When spring arrives, it is time for brooders to raise chickens. How to deal with changes in the spring climate and ensure the healthy growth of chicks is a matter of concern to everyone. Now we will introduce the main points of spring brooding. Do a good job of disinfection Before the chicks go into the house, the chicken house is thoroughly cleaned and rinsed, then formalin is used for fumigation. After closing the doors and windows for 12-24 hours, the doors and windows are opened for ventilation. All utensils were sterilized with 0.2% potassium permanganate solution or bleach. After these jobs are done, you can pick up the brood. Pay attention to drinking water Before the chicks start eating, they must first give water. In the first few days, add 5% glucose and 1.5% electrolytic multidimensional to the drinking water to help eliminate fatigue, restore physical strength as soon as possible, clean the gastrointestinal tract, promote the meconium excretion of chickens, and add probiotics to prevent Salmonella and Escherichia coli. And other intestinal diseases. Drinking cold water should be used for drinking water, and warming should be done in advance so that the water temperature is basically the same as the room temperature for brooding. Full price feed supplements Chicks can be eaten 24 to 36 hours after hatching. Fresh-started feed requires fresh, moderate grain size, easy for chicks to feed, and is rich in nutrients and digestible. Commonly used chick opening materials are commonly used. Feed 5 to 7 times a day. At the same time, pay attention to add enough start-up discs and replace them with small ones after 5 days to reduce feed wastage. The temperature should be suitable Although the temperature in spring has risen, the climate is still cold. Maintaining the proper temperature is the key to the success or failure of brooding. The body temperature regulation function of the chick is not perfect, and it is very sensitive to changes in the ambient temperature. The level of the ambient temperature has a direct impact on the growth and survival rate of the chick. Before entering the brood, the brooding house must be pre-heated to meet the temperature requirements for brooding. First, chicks in the first week of incubating in the first spring require a chicken house temperature of 35°C to 36°C, and then decrement by 2°C to 3°C per week until the shepherd temperature is 21°C to 22°C, and the temperature should be maintained until the brooding. End. Second, according to the chicken's response, this is also a problem that the farmer should pay attention to. When the temperature is too low, the chickens scream and pile up. When the temperature is too high, they are scattered and have wheezing. The temperature is suitable for the birds to distribute evenly and lively. It is also possible to use a thermometer and sensory combination to determine if the temperature is suitable. Special mention must be made here. For example, if the coal briquettes are used for heating, special coke ovens must be heated in the coops. That is, the chimney must be installed above the coal briquettes. The top of the chimney should be provided with a fume hood to prevent smoke. Carbon monoxide poisoning and hypoxia. Adjust humidity The proper humidity can keep the moisture in the chicks from evaporating and improve the survival rate of the chicks. Under normal circumstances, before 10 days of age, due to the higher temperature of brooding, the relative humidity of the air is often too low, and attention must be paid to the replenishment of room moisture. The brooding chamber can be placed in a basin to humidify the relative humidity of the brooding room to 60% to 65%. . After 10 days of age, as the age grows and the weight gains, the feed intake, water intake, respiratory capacity, and fecal output of chicks increase day by day, and the brooding temperature decreases again week by week. It is easy to cause indoor humidity and The schistosomiasis fungal poisoning, chicks are not suitable for this humid environment. Therefore, the brooding room should be enhanced ventilation, diligent replacement litter, add water to prevent the water spilled on the ground or litter, timely replacement of agglomerated dunnage, as far as possible the relative humidity of the brooding room is controlled at 55% to 60%. Timely ventilation In the brooding stage, due to the high temperature of the chicken house, the chicks have a higher density, and the chicken manure and the feed are easily corrupted and fermented, resulting in large amounts of ammonia, carbon dioxide and other harmful gases. When the concentration of ammonia in the house reaches a certain amount, people feel uncomfortable. In addition, in order to save costs, many chicken farmers in winter and spring spend most of their time heating with a coal ball furnace, and easily produce harmful gases such as carbon monoxide, carbon dioxide, and hydrogen sulfide. Enhance the ventilation of the brooding room to keep the air fresh in the brooding room. In order to solve the contradiction between ventilation and heat preservation, the temperature of the brooding room should be increased by 1°C~2°C before ventilating. After the ventilation is completed, the temperature is reduced to the original room temperature. Ventilation time is best before and after noon on sunny days, ventilation should be carried out slowly. The degree of opening of doors and windows should be from small to large, and finally be half open. Don't suddenly open the doors and windows, let the cold wind blow straight. Control the light Reasonable illumination is beneficial to the growth and development of chicks. The light is irradiated for 24 hours from 1 to 3 days, and the illumination time from 4 to 14 days is 16 to 19 hours. Natural illumination is adopted after 15 days of age. Light intensity, in every 15 square meters of the chicken house, in the first week with a 100 watt bulb suspended in 1.5 meters high position, the second week began to switch to 60 watt bulbs, 3 weeks after the use of 25 watts of energy-saving lamps . Reasonable density A reasonable density allows the chicks to feed evenly, keeping the chickens organized and healthy. The size of the density should be appropriately adjusted according to the age, breed, feeding method, season, and structure of the chicken house. The reasonable density of broiler chickens on weekdays is: 0 to 4 weeks old, 20 to 25 birds per square meter; 5 to 7 weeks old, 10 to 20 birds per square meter. The reasonable density of online brooding is from 0 to 4 weeks of age 24 to 28 per square meter; from 5 to 7 weeks of age, 15 to 20 per square meter. Sichuan Agricultural University teacher Shu Gang finishing Chicks should be strengthened for epidemic prevention In spring, raising chickens should be strengthened first. Specific should be based on local conditions, choose a reasonable immunization program vaccination. Especially when vaccinating you should pay attention to the following questions: Bird flu, Newcastle disease, bursa of Fabricius, fowlpox, and transmission must be done and the time of vaccination is in line with the age of the flock; vaccination methods (mainly eye drops, nose drops, injections, fleas, etc.) are available for various vaccines. Its strict regulations should be followed according to the instructions; vaccine dilution is usually done with special diluent or distilled water plus skimmed milk powder. The released vaccine must be used within the specified time; each chicken should be vaccinated; attention should be paid to the storage of the vaccine. Do not spray and drink water for 24 hours before and after eye drops and intranasal immunization. In addition to proper use and selection of vaccine, SPF vaccine must be used by regular manufacturers. In addition, the chicken house must be sterilized on a regular basis to keep the house dry, clean and hygienic. During the brooding period, traditional Chinese medicines and probiotics can be properly added to the feed and drinking water to improve the resistance of the flock; Dead chickens should be kept away from the burning or deep-buried chicken house.
