Autumn is a golden period for pig farmers. At this stage, the swine scrofula is faster. If the pig farmers pay attention to preventing cold, preventing disease, increasing feed nutrition and ventilation in the pig house, the pig-raising benefit is more obvious. To this end, the author introduced the points of safe and efficient pig raising in the autumn to everyone, hoping to help the majority of pig farmers and obtain higher aquaculture benefits.
First, pay attention to do a good job of cold
From the hot summer to the cool autumn, the temperature dropped greatly, and the temperature difference between day and night reached 10°C, which will have a certain impact on the growth of pigs. Therefore, we should take appropriate measures to control the temperature inside the pig house and grasp the optimum temperature for large pigs and piglets. The specific measures are:
1. Renovate doors and windows to prevent air leakage. Covering materials can be used for grass or plastic film.
2. Place hay in the pig house to prevent it from getting wet.
3. Conditions can use heating, infrared light bulbs or construct a greenhouse in a sheltered corner of a pig house. The size of the greenhouse depends on the number of pigs. The specific method is: build a wall about 1 meter high, leave a small door for pigs to enter and leave freely, cover the upper part with straw and store hay inside. No conditions can be used to cover plastic sheets, stoves and other measures to keep the pig house at a suitable ambient temperature.
Second, adjust feed nutrition
Autumn pigs, in addition to strengthening conventional feed management, but also do a good job of pig feed reserves and fattening fertilizer work. With the arrival of autumn and winter seasons, it is necessary to adjust feed formulas and increase feed nutrition, with the emphasis on increasing energy feeds and increasing pig feed intake. Increase the proportion of corn in the feed to more than 60%, and conditionally add 1% vegetable oil, so that it can be more suitable for the growth needs of pigs.
Third, strengthen the epidemic prevention
According to the epidemiological characteristics of infectious diseases, it is easy to have large-scale infectious diseases in the autumn, but due to the variable temperature, it is easy to induce pig disease. Therefore, it is still necessary to do a good job of epidemic prevention in accordance with the epidemic prevention regulations, with emphasis on the prevention of five epidemics of swine pneumoconiosis, swine fever, swine erysipelas, swine pneumonia and swine flu. Also pay attention to anti-erythrocythemia, swine cold, and swine streptococcus The occurrence of diseases, infectious gastroenteritis and other diseases. Pig farmers must also step up the cleaning and disinfection of pig houses. They usually clean their houses once a day and disinfect them once a day for 3 days to prevent the growth of bacteria.
Fourth, pay attention to ventilation
While keeping the pig house warm, we must also pay attention to strengthening ventilation to prevent air pollution. The most effective measure for ventilation is to open a ventilation hole on the ceiling. However, ventilation should be controlled, sunny days, more ventilation, less rainy days, ventilation, time to choose when the temperature is higher to ventilation, generally in the morning 10 am to 3 pm this time is the best time for ventilation.
Fifth, prevent feed poisoning
Autumn pigs, in addition to strengthening the conventional feed management, but also do a good job of feed reserves and fattening. Due to the rainy autumn season, if there are too many harvests for green fodder and improper storage and processing, it will be prone to mildew and will be accumulated too long. The nitrates contained in the grass will form highly toxic nitrites. If the pigs eat it, they will be poisoned or severely damaged. Hypoxia and suffocation died. Ren Xiuzhi

As you know, blueberry flavor has always been popular with people. Therefore, we have developed and produced blueberry-flavored cigarette substitutes to help people feel the comfort of nature anytime, anywhere.
