1. Choose the premix. The premix is ​​the core of the feed. Choosing a reliable, cost-effective premix plant will make the chicken half successful. The choice of premix depends first on the quality assurance of the manufacturer. The relatively large-scale and group-oriented companies are relatively reliable in terms of quality, and it is advisable to choose a manufacturer that has passed ISO9000 quality system certification. When choosing premixes, please also pay attention to vitamins, amino acids and other nutritional indicators. In general, higher levels of vitamins and amino acids can increase the immunity and resistance of laying hens. If the amount of corn in the manufacturer's formula is less than 64% and the amount of protein raw materials added is more than 24%, the protein content of the formula material is high and the energy is low, and the feed intake of such feed layers is large, but The rate of death scouring is high, and the peak time for egg production is short and the efficiency is poor. 2. Improve energy materials. In winter, when the temperature is low, the need for maintaining the energy of laying hens increases. Therefore, the energy in the feed should be properly increased, and more energy-intensive feeds such as oil and corn should be added. Some chicken farms (households) use their own ingredients and have always used a formula. They are invariable. At the same time, because of different sources of raw materials, the content of ingredients is not the same, so that protein, energy, minerals, etc. are high or low, and normal feeding occurs. Extraordinary, and the rate of egg production decreased to varying degrees, producing soft eggs, thin preserved eggs, etc., some chicken production rate is not at the peak, and then there has been crown atrophy, pubic constriction and so on. It is advisable to use a reasonable full price material and add some energy feeds such as corn and soybean meal. It is worth noting that mildew from corn will cause loss of nutrients, reduce nutrient use efficiency, raise the temperature of feedstuffs contaminated by mold, and emit an unpleasant musty smell, which will cause the feed intake and production of layer chickens. The egg rate decreased. The moisture content of soybean meal should not exceed 13%. If the color of the soybean meal is whitish, it indicates that urease is too high and it is easy to cause chicken diarrhea; if it is red, it indicates that the urease is low, the protein denatures, and the nutritional value is lost. Therefore pay attention to identification. 3. Feeding warm material. In cold weather in winter, layers require more energy than other seasons. It is necessary to appropriately increase the proportion of warm and high-energy feeds such as corn and bean cakes. When using premixes, it is necessary to adjust the feed formulation to meet the requirements of laying hens, generally adding 1% of fat and reducing 0.5% of stone powder. The specific formula for the warm winter feed for laying hens is: corn 64%, bran 3%, soybean cake 17.2%, loquat leaf powder 2%, fish meal 2.5%, blood meal 4.8%, bone meal 2%, shell powder 4.5%. The formula has a crude protein content of 16.8%, metabolizable energy of 11.49 MJ/kg, calcium of 3.2%, and phosphorus of 0.6%. Eggs are more suitable. Feed 3 to 4 times a day, feed dry powder, drink the same clean water as Sherwin, and pay attention to feeding grit. 4. Increase the feeding efficiency. High-efficiency material (ie, high-efficiency material) is a comprehensive nutrient additive for methionine. The main component is methionine, which is equipped with various vitamins, antibiotics, and trace elements. In terms of biological characteristics, it can not only achieve the effect of 5%~10% Peruvian fishmeal diet, but also replace green feed. Proper feeding of laying hens can enhance their resistance to disease, prevent diseases, meet the needs of trace elements and nutrient growth of laying hens, and achieve the purpose of increasing egg production rate. 5. Increase the amount of feeding. In winter, the temperature is particularly low. Layers must feed enough nutrients from the feed to resist the cold in order to ensure a healthy and productive egg. For this reason, the method of increasing the number of feedings may be used to promote the multiple feeding of layer chickens, that is, feeding 3 to 4 times during the day and feeding once more at 8 o'clock in the evening. 6. Pay attention to disease prevention. Winter is a popular seasonal epidemic of respiratory infections in chickens. Once it is discovered, it should be immediately isolated and treated with appropriate drugs to make it recover soon. At the same time, every 5 days to 7 days with 100 poison and other disinfectants to disinfect the chicken house and the environment in order to avoid epidemics.
