In the early winter, it is the season changing period. Sudden cooling and light reduction reduce the indoor and outdoor temperature difference. The layer's own energy consumption begins to increase. If egg management is not managed scientifically, the laying rate of laying hens can easily be reduced. Even stop production. In order to give full play to the winter production performance of laying hens, prolong the peak period of egg production and increase the egg production rate, in addition to creating a suitable egg production environment for laying hens and reducing the stress of various unfavorable factors, scientific feeding is extremely important.
Choose early winter premix
The premix is ​​the core of the feed. Choosing a reliable, cost-effective premix plant will make the chicken half successful. It is not advisable for some chicken farms to choose the market for cheap feed. The choice of premix depends first on the quality assurance of the manufacturer. The relatively large-scale, group-based companies are relatively reliable in terms of quality, and it is advisable to choose a manufacturer that has passed quality system certification. When choosing premixes, please also pay attention to vitamins, amino acids and other nutritional indicators. Relatively speaking, higher vitamin and amino acid content can improve the immunity and disease resistance of laying hens.
Raise feed for energy feed
After winter, the temperature is low, and the maintenance energy of laying hens needs to be increased. Therefore, the energy in the feed should be properly increased, and some high-energy feeds such as oil and corn should be added. Some chicken farms (households) have their own ingredients and have been using a recipe. 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, normal or extraordinary feeding occurs, and egg production rate declines to varying degrees, and soft eggs, thin preserved eggs, etc. are produced. In some chickens, the egg production rate is not at the peak, followed by crown shrinkage and pubic contraction. 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 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 urease is low, protein denaturation, and loses its nutritional value, so it is necessary to pay attention to identification.
Feed more warm feed
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 feed for laying hens in winter is: corn 64%, bran 3%, bean 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%, metabolic energy of 11.49 MJ/kg, calcium of 3.2%, and phosphorus of 0.6%. Feed 3-4 times a day, feed dry powder, drink the same clean water as Sherwin, and pay attention to feeding grit.
Feeding methionine ingredients
Methionine ingredients contain a variety of 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.
Appropriately increase the amount of feeding
In winter, the temperature is particularly low. Layers must feed enough nutrients from the feed to resist the cold and ensure that a healthy body can produce more eggs. For this reason, the method of increasing the number of feedings may be used to urge the layers to feed more than once, ie 3-4 times during the day and one more at 8 o'clock in the evening.
Pay attention to disease prevention and disinfection
In winter, due to the importance of heat preservation, there is a lot of dust and other harmful substances. Therefore, the sanitation and sanitation of the house should be strengthened. The drinking water pipe can be used to disinfect the potassium permanganate every two weeks, and at the same time, every 5 - Disinfect the chicken house and the environment with a 100-total-killer disinfectant to prevent epidemics. 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.
