Chicken and poultry breeding is bound to have an impact on the environment. Therefore, the construction site of the chicken house should be reasonably selected. At the same time, due to the use of fully automated broiler cages for indoor facilities, the density of chickens and poultry is relatively high, and the requirements for the breeding process and feeding conditions are high. , we should attach great importance to this.
1 ,The layout of the chicken house is reasonable: The structure of the house is economical and practical. Its orientation is in line with the local physical and geographical conditions. It is well-lighted, easy to ventilate, and easy to operate. It is beneficial for the summer to cool down during the summer, and conducive to heat preservation during the fall, winter and early spring. The layout of the house is reasonable, so that the production area and the non-production area are separated; the non-production area and the water source are in the upwind direction of the chicken farm; the dirty road and the clean road are separated and do not cross; the fecal field is located in the downwind direction of the chicken farm; the brooding house and breeding Separately, the brooding house is located on the windward side of the chicken farm. The site should be selected away from residential areas, convenient transportation, and away from the road. The terrain is dry and the sun is sunny. It is not shaded as early as possible in spring, and it is not windy in summer. It does not accumulate water after rain. Larger area, leaving room for development. Water resources are rich in pollution, easy to access, and adequate power is guaranteed. Understand the local bird disease epidemic and try to avoid the affected area or the area where the epidemic occurred. Avoid urban polluted areas and take appropriate environmental protection measures to minimize environmental pollution.
2 ,Reasonable feeding: Do not suddenly reload. At present, most chicken farms generally use full-price compound feeds. Because chickens have habits in feed intake, if they suddenly replace new feeds, they will affect the appetite and egg production of chickens, which will reduce the egg production rate. Do not feed raw grains. Some chicken farmers are accustomed to feeding chickens with raw grains such as corn and rice. This will not only reduce feed utilization but also cause harm to chickens. The correct method of feeding is to grind the raw grains such as corn and mix it with other ingredients such as bran, bean cake, and fishmeal, and then feed the chicken. It is necessary to ensure uninterrupted supply of clean drinking water, and to increase the amount of greens fed to increase the feeding capacity of laying hens. During the hot summer, care should be taken to provide clean cold water, and chopped watermelon rinds can also be fed daily. This will not only prevent the heat stroke of laying hens, but also increase the egg production rate of laying hens. Do not drink cold water in winter, to give clean and warm water, not only can prevent the laying hens cold sick, but also to maintain body heat.
3 ,appropriate light: light management can promote the growth of the chicken body, but also stimulate the reproductive system to accelerate the development of the ovary. Laying hens are very sensitive to light and use correct lighting to receive good egg production. The lighting time during the laying period can only be increased but not shortened. The lighting time required for the production of eggs must not be less than 12 hours and not more than 16 hours. Increase in light during the laying period is preferably 15 minutes per week or half an hour every two weeks, until 14 to 16 hours. The illumination length is more important than the illumination brightness. When the illumination length reaches 14 to 16 hours, the time for turning on and off the lamp should be fixed to prevent the chicken from producing stress.
4, Reduce stress: In the production process, any sudden changes in environmental conditions can cause frightened chickens and stress response. Any kind of stress will cause great harm to the chicken body, making it imbalanced in vivo. The outstanding performance is loss of appetite, nervousness, and even internal bleeding caused by indiscriminate collisions. Mortality rate rises, egg production rate decreases, and soft shell eggs are produced. Even after the stress is eliminated, the peak egg production is no longer achieved. . The factors that cause stress are climate, summer heat stress, cold winter stress, and environmental conditions, such as poor sanitation condition, excessive stocking density, poor ventilation and ventilation, high concentration of harmful gases, and sudden temperature and humidity changes; Management, such as feeding, improper drinking water, lighting program changes, external noise is too large, catch chickens, etc.; epidemic diseases, such as improper prevention of disease, infection and other diseases. In actual production, efforts should be made to reduce stress and minimize the damage. For example, if workers enter the coop, they should not wear colorful and colorful clothes. The specific time for laying hens to choose is to select the temperature suitable weather and avoid rainy weather. The hot summer season is best performed at night. It is easy to catch chickens at night and avoid frightening crowds and reducing stress. Therefore, we should carefully formulate and strictly implement scientific broiler house management procedures. The broiler house should be kept in a stable manner. The daily work procedures should not be changed easily, the actions should be steady, the sound should be light, and the number of times of entering and leaving the hen house should be reduced as much as possible to keep the hen house in a quiet environment.
With the deepening of the process of urbanization in China, the structure of the agricultural industry is gradually being adjusted, and the labor force is shifting from rural areas to cities from time to time. The traditional small-farm economy of rural units has been adjusted from time to time as a company farm with a large range and a high level of intensification. The presentation and development of the company's farms has led to an increase in the degree of agricultural mechanization and the liberation of the labor force. The planting industry is mainly represented by the integration of land resources and the application of field operations machinery. The performance in the aquaculture industry is that the original individual operations, the small-scale livestock rearing forms are gradually marginalized, and the amount of livestock is large and the amount of waste discharged is large. Farms with high levels of automation have become mainstream.
Chicken is the earliest domesticated animal of humans. The number of chickens being bred in the world today has surpassed humanity. It has been reported that the earliest history of human domestication of chickens dates back to 5400 BC. Although human bred chickens have many purposes such as appreciation, cockfighting, and entertainment, the main purpose is to enrich people's meat and to obtain cheap animal protein such as eggs. In the late 1920s and early 1930s, the United States established and launched the world's first commercial cage farm.
In the 1950s, some thriving countries also successively invented many modern chicken-raising machinery. At the same time, they also achieved great pauses in breeding good breeds, full-rate feed, poultry disease prevention, environmental control, and feeding management. Economic benefits. As chicken cages have obvious advantages in preventing infectious diseases, reducing consumption costs, and reducing the onslaught of the flock, they are immediately applied in Europe. After the 1980s, the United States and the Nordic countries strengthened their research and development in chicken engineering technology, environmental control, manure disposal and application, aquaculture equipment and equipment, and Haoxing machinery breeding technology.
