Don't change the material suddenly. At present, most chicken farmers generally use full-price compound feed. Because chickens have a habit of eating feed, if the new feed is suddenly changed, 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 accustomed to feeding chickens with raw grains such as corn and rice. This not only reduces the utilization rate of feed, but also harms the chickens. The correct feeding method is to crush raw grains such as corn and mix with other raw materials according to the formula, such as bran, bean cake, fish meal, etc., before feeding the chicken.
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 amount of feed should be increased appropriately to ensure that chicken growth and egg production are not affected by low temperature. Therefore, when raising chickens in winter, you should pay attention to the weather forecast. When the temperature drops by 3°C, you should add about 5 grams of feed to the chickens to get enough heat. When the temperature rises, the original feed amount should be restored immediately to avoid over fat. For laying hens with obesity, the egg production rate will drop or production will stop. You can reduce the feed before laying, or reduce the concentrate after laying, and feed roughage for prevention. You can also add choline to the feed and feed it for 10 days. lose weight.
In order to prevent blood spotted eggs, vitamin K can be added to the diet. In order to prevent the lack of calcium and phosphorus in caged laying hens from causing rough eggshells or laying soft-shelled eggs, or even standing unsteady and paralyzed, 3% calcium powder or 5% gypsum powder can be added to the feed, and some charcoal can be added at the same time Ashes or small sand particles. Pay attention to supplement enough vitamin E after giving birth to maintain the normal function of reproductive organs and prevent fallopian tube stenosis from causing diseases such as rectal prolapse. In winter, there is little low temperature and light, vitamin D should be added to prevent the occurrence of vitamin D deficiency due to the inability of caged laying hens to receive outdoor light. In severe winter, feed the chickens with 60° white wine mixed feed. Mixing 30-40 grams of white wine per kilogram of feed can increase the egg production rate by about 20% and enhance the chicken's disease resistance.
It is necessary to ensure an uninterrupted and adequate supply of clean drinking water, and appropriately increase the amount of green vegetables fed to improve the feeding ability of the laying hens. In the hot summer, you should pay attention to supplying clean and cold water, and you can also feed chopped watermelon rinds every day, which can not only prevent heatstroke in laying hens, but also increase the laying rate of laying hens. Don't drink cold water in winter, but give clean warm water to prevent cold and sickness of the gastrointestinal tract of laying hens, but also to keep the body warm.
