diseases. In order to prevent dampness and rain, the house should be frequently replaced with hay and loose soil to allow pigs to urinate at designated points, keep the prone place clean and dry, and provide a comfortable living environment for pigs to promote the growth of fattening pigs in autumn Development and health.

　　Increase stocking density. Increase the stocking density appropriately so that the pigs can sleep next to each other, which can warm each other and increase the pen temperature. Feed more high-calorie feeds to increase the heat in the pigs.

　　The weather gets cold in autumn, so while keeping the heat preservation, it is necessary to do a good job of ventilation of the pig house. During the day when the temperature is high from 10:30 am to 3:30 pm, open the windows of the pig house for ventilation and purify the air in the house. However, the ventilation must be controlled, with more ventilation on sunny and warm days, and less ventilation on cloudy and cold days, so that ventilation and heat preservation should be coordinated.

　　Health care, epidemic prevention and disease treatment

　　The changeable weather in autumn can easily induce pigs to get sick. Therefore, pig farms should do a good job of pig epidemic prevention in accordance with epidemic prevention regulations, focusing on preventing diseases such as epierythrocytosis, swine cold, swine fever, transmissible gastroenteritis and piglet dysentery.

　　1. It is necessary to strengthen the cleaning and disinfection of the pig house. Generally, the house is cleaned once a day, and disinfection with pigs or drinking water is carried out every three days. The environment and roads outside the house should also be disinfected at the same time.

　　2. Try to avoid stress factors that lead to immune suppression in pigs, such as temperature, environment, mycotoxins, etc. You can add multi-dimensional electrolytes to feed or drinking water two days before the weather changes to reduce piglet stress and reduce stress to pigs The impact of coming to enhance the immunity of piglets and improve disease resistance.

　　3. Once a pig disease is found, it must be strictly sealed off, disinfected, immunized, and treated with dead pig carcasses as required. If there is an epidemic in the surrounding area, in addition to disinfecting the pig house, it is strictly forbidden to enter the foreign personnel and vehicles Pig farms, their vehicles and personnel must be thoroughly disinfected after returning from the epidemic area.

　　Scientific and reasonable nutritional supply

　　With the arrival of autumn, the temperature is suitable, the physiological metabolism of pigs is strong, the feed intake is higher than that in summer, and the growth rate becomes faster. Therefore, it is necessary to provide the pigs with a balanced and comprehensive feed. A high level of nutritional supply can meet the nutritional needs of pigs and can effectively improve the ability of pigs to resist diseases. Therefore, in production, it is necessary to scientifically feed diets with different nutritional levels according to the different growth stages of pigs, and adjust the diet formula in time according to the changes in pig weight and feeding situation.
