Abstract: The laying hen is the money printing machine of the chicken farm, so it is very important to do a good job in daily breeding management. As we all know, not all laying hens can produce high output. Only if they can be raised and managed well, can the benefits of laying hen farms be ensured and a good sustainable development be maintained. To this end, we will introduce the key management methods of laying hen breeding technology for the breeding and management of laying hens. Let's take a look together.
Laying hens are the money printing machines of chicken farms, so it is very important to do a good job in daily breeding management. As we all know, not all laying hens can produce high output. Only if they can be raised and managed well, can the benefits of laying hen farms be ensured and a good sustainable development be maintained. To this end, we will introduce the key management methods of laying hen breeding technology for the breeding and management of laying hens. Let's take a look together.
1. Preparation before laying hens
Reasonable layout of chicken coop
The structure of the house is economical and practical. Its orientation conforms to the local natural geographical conditions, with good lighting, easy ventilation, and easy operation. It is conducive to heatstroke prevention and cooling in summer, and is conducive to thermal insulation and cold prevention in autumn, 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 manure farm is located in the downwind direction of the chicken farm; The Chicken Cages are separated, and the brooding house is located upwind of the chicken farm. The site should be selected away from residential areas, with convenient transportation and away from roads. The terrain is dry and the sun is full, so try not to block the light in early spring, not block the wind in summer, and not accumulate water after rain. The area is large and there is room for development. The water resources are abundant and pollution-free, easy to use, and the electricity is sufficient and guaranteed. Understand the local epidemic situation of poultry diseases, and try to avoid epidemic areas or areas where epidemics have occurred. Avoid urban polluted areas and take appropriate environmental protection measures to minimize environmental pollution.
Second, the feeding method of laying hens
Reasonable feeding
Do not change materials suddenly. At present, most professional chicken raising households generally use full-price compound feed. Since chickens are accustomed to the feed they eat, if they suddenly change to new feed, it will affect the chicken's appetite and egg production, and reduce the egg production rate.
Do not feed raw food. Some chicken farmers are used to feeding their chickens with raw grains such as corn and rice, which not only reduces the utilization rate of feed, but also harms the chickens. The correct feeding method is to pulverize the raw grains such as corn, match other raw materials according to the formula, such as bran, bean cake, fish meal, etc., and then feed the chickens.
Adjust the feeding amount according to the temperature. In winter, the proportion of high-energy feed should be increased in the feed, and the protein content should be appropriately reduced. The feeding amount is appropriately increased to ensure that chicken growth and egg production are not affected by low temperature. Therefore, when raising chickens in winter, pay attention to the weather forecast. When the temperature drops by 3 °C, about 5 grams of feed should be added to the chickens so that the chickens can get enough heat. When the temperature rises, the original feed amount should be restored immediately to avoid excessive fat. For obese laying hens, the egg production rate will decrease or stop production. You can reduce the feed before laying eggs, or reduce the concentrate after laying eggs, and supplement roughage for prevention. You can also add choline to the feed for 10 days. lose weight.
To prevent blood-spotted eggs, vitamin K can be added to the diet. In order to prevent the caged laying hens from being deficient in calcium and phosphorus, resulting in rough eggshells or soft-shelled eggs, or even standing unsteady and paralyzed to death, 3% calcium powder or 5% gypsum powder can be added to the feed, and some charcoal can be added at the same time. Ash or small grains of sand. Pay attention to supplementing enough vitamin E after the start of labor to maintain the normal function of reproductive organs and prevent diseases such as rectal prolapse caused by stenosis of the fallopian tubes. In winter, there is little light and low temperature, and vitamin D should be supplemented to prevent vitamin D deficiency due to the inability of caged laying hens to receive outdoor light. In severe winter, feeding chickens with 60° liquor mixed with feed, mixing 30-40 grams of liquor per kilogram of feed, the egg production rate can be increased by about 20%, and the disease resistance of chickens can also be enhanced.
It is necessary to ensure uninterrupted and sufficient supply of clean drinking water, and appropriately increase the feeding amount of green vegetables to improve the feeding ability of laying hens. In hot summer, we should pay attention to supplying clean cold water, and we can also feed chopped watermelon rind every day, which can not only prevent heat stroke in laying hens, but also improve the laying rate of laying hens. Do not drink cold water in winter, but give clean warm water, which can not only prevent laying hens from gastrointestinal cold and illness, but also maintain body heat.
3. Management of laying hens
1. Appropriate lighting
Light management can promote the growth and development of chickens, and can also stimulate the reproductive system to accelerate the development of ovaries. Laying hens are very sensitive to light, and only the correct light can be used to receive good laying results. The light time in the egg-laying stage can only be increased but not shortened, and the light time required for egg-laying shall not be less than 12 hours, and the longest shall not exceed 16 hours. During the laying period, it is better to increase the light at a rate of 15 minutes per week or half an hour every two weeks until 14 to 16 hours. The length of light is more important than the brightness of lighting. When the length of light reaches 14 to 16 hours, the time of turning on and off the lights should be fixed to prevent chickens from being stressed.
2. Reduce stress
In the production process, any sudden changes in environmental conditions can cause panic in the chickens and cause stress reactions. Any kind of stress will cause great harm to the chickens and make their homeostasis unbalanced. The outstanding performance is appetite. Depression, nervousness, and even death due to internal bleeding caused by ramming, the mortality rate increases, the egg production rate decreases, and soft-shell eggs are produced. Even after the stress is eliminated, the egg production peak will never be reached. The factors that cause stress include climate, heat stress in summer, and cold stress in winter; environmental factors, such as poor sanitation of chicken houses, excessive stocking density, poor ventilation, high concentration of harmful gases, and sudden changes in temperature and humidity; Management, such as improper feeding, drinking water, changing lighting programs, too much noise from the outside world, epidemic prevention and catching chickens, etc.; epidemic diseases, such as improper epidemic prevention, infection of epidemic diseases, etc. In actual production, efforts should be made to reduce stress and minimize harm. For example, staff should not wear brightly colored clothes when they enter the chicken coop. The specific time for laying hens to transfer to the group should choose the weather with suitable temperature and avoid rainy weather. In hot summer, it is best to do it at night. It is easy to catch chickens at night, and it can avoid shocking herds and reduce stress. Therefore, scientific chicken house management procedures should be carefully formulated and strictly implemented. The chicken house should be fixed and the daily work procedures should not be easily changed. The movements should be stable and the sound should be light. .
3. Strengthen epidemic prevention and hygiene work
Prevent outsiders from entering the breeding area and chicken coop. The breeding staff must disinfect before entering, maintain the hygiene of the chicken coop environment, drinking water and feed, and regularly carry out disinfection with chickens and inside and outside the chicken farm to reduce the occurrence of diseases. In addition, pay attention to the use of some antibacterial drugs and Chinese herbal medicines to prevent the occurrence of colibacillosis and mycoplasmosis.
