Spring chicken brooding points

First, the advantages of spring brooding As the saying goes: The one-year plan is spring. This is also true for broiler laying hens. During the four seasons, brooding is best in spring. This is because: 1. The temperature is appropriate: The temperature gradually warms up from March to April each year, and the light is gradually extended, which is conducive to the growth and development of young chickens. The survival rate is also high. 2, suitable for the opening period: the spring brooding generally open from the 8th to the September of the year, can avoid the hot summer, from the impact of high temperature, but also because of the low egg production of old chicken, the listing of eggs and improve the eggs Economic Value. 3. Long duration of egg production and more egg production: Spring chicks can be eliminated by the end of summer and autumn of the second year after opening in the fall of the year. This will not only facilitate the renewal of chickens but also maintain a high production level. . Second, the preparation before entering the young 1. Disinfection: The specific disinfection steps are: (1) Thoroughly clean the chicken house, including every corner of the ground, roof, window sill, etc., can not leave a dead end. (2) Rinse the chicken house. Rinse the chicken house from the inside out with water, rinse it and open it to dry one day. (3) The troughs, troughs, and other feeding utensils used for brooding are soaked in the sun and exposed to sunlight for 2 days. (4) Fill the rat hole during the empty period to repair the leaky roof and damaged doors and windows. Use 20% lime plaster to paint the walls. If the interior is a land surface, you can shovel the surface soil and mix it with quicklime. Can play a role in disinfection. (5) Disinfect with 3 to 4% fire alkali (sodium hydroxide). The water temperature should be about 40°C. Spraying should be 1 to 2 liters per cubic meter. The spraying should be uniform and no dead angles should be left. (6) 2 days after spraying and disinfecting, put the disinfected troughs, sinks, and other utensils into the chicken house, close the doors and windows, and conduct fumigation. Pay attention to all loopholes in the chicken house, gaps in doors and windows, and prevent the loss of fumigated gas. Because the temperature in spring is still low, in order to ensure the fumigation effect, the chicken house needs to be heated and humidified. The fumigation time is appropriate for 24 to 48 hours. After the fumigation is completed, the window can be opened for 12 hours for ventilation, and then closed again for use. 2. Laying of litter: farmers should lay litter in the brooding room 3 to 4 days before hatching. (1) For most of the cultivators on the ground used by most rural farmers, soft litter must be placed in the brooding room. The litter should be dry, loose, absorbent, and suitable for fertilizer. Straw, wheat straw, rice husk, sawdust, etc. are commonly used as litter for feeding. No matter what kind of litter you use, be sure not to mold, so as not to induce the chicken aspergillosis. (2) Laying method: The litter is first disinfected with a disinfectant spray in a clean environment and then exposed to sunlight for 2 days. Finally put in a fumigation brooding room, the thickness is about 15 to 20 cm, careful not to cut too much. (3) Preheating test temperature: For the first time brooding farmers, it is particularly important to warm up and test the temperature. Take the example of stove brooding commonly used by rural farmers. Before the brooding, the stove should be ignited to observe whether the temperature can reach the maximum temperature required for brooding. Pay special attention to whether the night and day temperatures are the same; and Check carefully whether the chimney is leaking smoke and whether the joint between the chimney and the roof or wall is safe to eliminate the fire hazard. If problems are found in this process, they should be resolved in time before entering the chicks. Third, the daily management of broiler chicks 1. Temperature: In the first few days, the brooding temperature should be maintained at 32-33°C. Later, with the growth of the chicks, the temperature can be gradually reduced, usually falling 2°C per week, until 4 weeks of age. It can be finally maintained at 22-23 °C. For experienced breeders, whether or not the brooding temperature is appropriate can be fully observed through the performance and behavior of the chicks. The specific methods are: (1) The temperature is normal: the chicks are lively and active, have a strong appetite, adequate drinking water, and normal feces. The feathers are shiny, evenly distributed on the bedding, quiet at night, and stretch the neck to rest. (2) Excessive temperature: The chicks are far away from the heat source, their wings are open, their necks open, their mouths are open, and their drinking water is frequent. (3) The temperature is too low: The chicks get together and approach the heat source and scream. In addition, in the brooding process in the temperature control and control, but also pay attention to these points: we must ensure that the brooding temperature balance, the daily temperature difference should not exceed 2 °C, in particular, to avoid a sudden drop in temperature at night; temperature meter with Proofreading should be done in a place higher than the chick's back, and should be evenly hung in the room, but it must be kept away from the stove to avoid errors. The temperature control should be flexible and the data displayed by the thermometer should be combined with the status of the chicks. The temperature of weak chicks or sick chicks is 1 to 2°C higher than that of healthy chicks, 1°C higher during the night than during the day, and 1°C higher than normal during vaccination. 2, humidity: chicks like to dry and afraid of moisture, 1 to 7 days when the broiler room humidity should be maintained at 60 to 70%, 1 week later, with the increase in body weight and water metabolism, can be maintained at 50 ~ 60 %. In the brooding process, there are several ways to maintain indoor humidity: The steam method is to use a pot or kettle to boil water on the stove, which provides the chicks with drinking water and increased humidity; the spray method is to spray warm water with a sprayer to increase Humidity can be disinfected with the disinfectant solution, but the sprayer should be kept away from direct contact with the chicks. The ground watering method is to spray the surrounding walls or litter, but the amount of water should not be too large. 3. Ventilation: The chicks have higher density and more excrement. The feces and litter under the action of microorganisms, temperature and moisture generate harmful gases such as ammonia and hydrogen sulfide. These harmful gases all seriously affect the growth and development of the chicks. One of the important reasons for reducing the disease resistance of chicks or causing other diseases. Therefore, under the premise of considering heat preservation, it is necessary to strengthen ventilation in the brooding room. When ventilating and ventilating, pay attention to: (1) Before ventilating, increase the room temperature by 2°C. This will not cause the temperature to decrease after ventilation. (2) When looking at the direction of ventilation, the wind direction must be small. The window on the windward side must be smaller, and the leeward side can be larger. Avoid external cold air blowing directly onto the chicks. 4. Light: The effect of light on chicks is mainly manifested in two aspects: first, light time, and second, light intensity. (1) Illumination time: 1 to 3 days of age, 23 hours of light can be used, this can promote the activities of chicks to facilitate eating and drinking. After 3 days, natural light can be used, or it can be lowered by 2 hours in a week until no lights are turned on at night. (2) Light intensity: In the light intensity, the intensity in the first week can be slightly larger, with 3 to 5 watts per square meter of ground, and can be reduced to 1 to 3 watts after the second week, which can prevent the light from being too strong. Causes chicks to lick. 5. Density: Feeding density has a great influence on the growth and development of chickens. Generally, from 1 to 6 weeks of age, 20 to 25 chicks can be reared on the ground. If the density is too high, the flock will be crowded, the food intake will be uneven, and the individual development will be irregular. It is easy to infect the disease and cause sputum; if the density is too small, the survival rate may be higher, but it is unfavorable and uneconomical for insulation. 6. Environmental hygiene: Keep the ground and litter in the brooding room dry and pay attention to the cleanliness of the feeding equipment. We must formulate a strict internal and external environment disinfection system in line with the principle of "prevention first, combination of prevention and control, and prevention against treatment." (1) Forbidden outsiders to enter freely. (2) Chicken litter and litter should not be piled up after being cleared. Dead chickens should be buried or incinerated. (3) The brooding room door should be equipped with a disinfection pool or sprinkle lime, disinfectant should be replaced frequently. (4) Disinfect the interior and exterior environment regularly or irregularly. When disinfecting with chickens, care should be taken that the sprayed droplets should not be too large, otherwise it may easily cause respiratory diseases in chicks. 7, cut off lice (1) in the chicks 6 to 10 days old off the best. When dying, we must avoid the time of vaccination. Some farmers or breeder technical service personnel plan to save time, often vaccinating chicken inoculum or oil seedling injections together with the severed worm. This will not only result in immune failure, but also cause Double stress reduces chick disease resistance. (2) Vitamin K3 powder should be added to drinking water for 1 day before and after cutting off, in order to reduce bleeding and avoid staphylococcal infection. In addition, multiple electrolytic cubes should be mixed in the feed to prevent stress. (3) Eat freely within 1 to 2 days after cutting off. Feeding should be done in the feed chute so as not to have a painful feeling on the bottom of the trough. In short, egg chicks are very delicate, and slight negligence during brooding will have a great impact on the health of the chicks. Therefore, the farmers must carefully manage the rearing and brooding so that the rearing and laying Period laid a good foundation.
