First, disinfection The chickens are cleaned and rinsed thoroughly before entering the house. Then formalin and potassium permanganate are used for fumigation. After 12 to 24 hours, the doors and windows are opened for ventilation. All utensils were cleaned and disinfected with 0.2% potassium permanganate solution. After these jobs are done, you can pick up the brood. Second, drinking water Before the chicks start eating, they must first give drinking water. In the first few days, one-tenth of potassium permanganate can be added to the drinking water to sterilize drinking water, clean the gastrointestinal tract, and promote the role of chicken meconium discharge. After long-distance transportation of chicks, about 5% of glucose can be added to drinking water to help eliminate fatigue and restore stamina as quickly as possible. At the same time, 0.01% of chicks can be added to open mouth or salad Shaxing drinking water to prevent Salmonella and E. coli. Disease. The drinking water used should be warmed in advance so that the water temperature is basically the same as the room temperature for brooding. Third, open food Chicks can be eaten 24 to 36 hours after hatching. Fresh-started feed requires fresh, moderate grain size, easy for chicks to feed, and nutritious, easily digestible, commonly used are broken corn, millet, broken rice, crushed wheat and so on. The starter can be boiled until it matures and then fed, which is beneficial to the digestion of the chicks. Feed 5 to 7 times a day, feed 2 to 3 days after starting the diet, gradually use chick mix to feed normally and feed 4 to 5 times a day. Can be mixed in the feed on the 4th day after the hatching of chopped cabbage leaves or young grass, feeding about 10% of the total amount of feed, after gradually increase the amount of feed, can account for the total amount of feed 20%~30%. Fourth, nutrition The digestive function of the chicks is not yet fully developed. Feed a nutritious, easily digestible, full-priced compound feed. For example, chicks that are intended to be developed by the feed company can be fed with grass pellets and fed with appropriate amount of green and blue succulent feed. The use of a single feed or a nutrient-poor feed is not conducive to the growth and development of the chicks. Fifth, temperature 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. One is that chicks within the first week of brooding in the first spring require chicken house temperatures of 35°C to 36°C. After that, decrement by 2°C to 3°C every week until the shepherd temperature is 21°C to 22°C, and the temperature should be maintained until the brooding is over. 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 should be made here, such as heating with coal briquettes, must be used to heat special coal furnace broiler, that is, must be installed in the top of the coal briquettes chimney, the top of the chimney with a hood, and smoke out The hood mouth must go downwind, or it will inevitably cause carbon monoxide poisoning in the chick once it is poured into the wind. Six, 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 the brooding, the relative humidity of the air is often too low, and attention must be paid to replenishing the indoor moisture so that the relative humidity of the brooding room reaches 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 Because of the fungal poisoning of the chute padding, the chicks are not suitable for this humid environment. Therefore, the brooder room should be ventilated, be changed frequently with litter, and should be prevented from spilling on the ground or litter when adding drinking water. The relative humidity of the brooding room is controlled from 55% to 60%. VII. 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 flat-raised chicks is: 0 to 4 weeks of age, 20 to 25 per square meter; 5 to 7 weeks of age, 10 to 20 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. Eight, lighting Reasonable illumination time is: 24-hour light from 1 to 3 days of age, 16 to 19 hours of light from 4 to 14 days of age, and natural illumination after 15 days of age. Light intensity, according to every 15 square meters of the chicken house, the first week with a 40-watt bulb suspended in a 2-meter-high position, the second week began to replace the 25-watt bulb. Nine, 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 to 2 °C before ventilating. After the ventilation is completed, the temperature is reduced to the original temperature. The ventilation time is best chosen before and after sunny noon. Ventilation and ventilation should be performed slowly. The opening degree of doors and windows should be from small to large, and finally it should be half-open state. Do not suddenly open the doors and windows, let the cold wind blow straight, so that the temperature suddenly drops. X. Epidemic prevention According to local conditions, choose a reasonable immunization program to vaccinate, especially in the vaccination should pay attention to the following issues. Vaccine species should be compatible with the age of the flock; all kinds of vaccine inoculation methods (mainly eye drops, nasal drops, injections, sputum, etc.) have strict regulations, should follow the instructions; vaccine dilution is generally used special dilution Liquid or distilled water plus skimmed milk powder, the release of the vaccine must be used within a specified time; each chicken should be vaccinated; pay attention to the storage of vaccine; do not spray and 24 hours before and after eye drops, intranasal immunization Drinking water disinfection, in addition to the correct use and selection of vaccines, must also use the regular manufacturer of SPF vaccine. In addition, the chicken house must be sterilized on a regular basis to keep the house dry, clean, and hygienic. Prophylactic medicines can be properly added in feed and drinking water during the brooding period; diseased chickens should be promptly isolated and treated, and dead chicken should be kept away from the house.
