Fall is a golden period for raising pigs for pig farmers. At this stage, the swine scrofula is relatively fast. If the pig farmers pay attention to preventing cold and disease, increasing feed nutrition and ventilation in the pig house, the pig-raising benefit is more obvious.
First, pay attention to cold
From hot summer to cool autumn, the temperature drops sharply, and the temperature difference between day and night reaches 10°C, which will have a certain impact on the growth of pigs. Therefore, appropriate measures should be taken to control the temperature inside the pig house and to determine the optimum temperature for pigs and piglets. The specific measures are:
1. Renovate windows and doors 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 size of the pig house. A wall of about 1 meter is laid, leaving a small door for pigs to come in and out freely. The upper part is covered with straw, and the inside is covered with hay. 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 the 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%, preferably plus 2.5% of pig feed additive, active pro-peptide. This can be more suitable for the growth needs of pigs.
Third, pay attention to pig house air quality
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, the time to choose a higher temperature for ventilation, generally from 10 am to 3 pm during this time is the best time for ventilation. Adding 2.5% of feed additives for pigs, active peptides, can effectively improve pig house air quality.
Fourth, prevent feed moldy
Due to the rainy autumn season, the feed is prone to mildew. Therefore, the procurement and storage of feed should be put on the agenda to prevent moldy feed. At the same time, pig feed additive, active peptide, must be added to the feed. Kidney-specific drug --- pig incompetence for 10 days. If green feed is harvested excessively and stored improperly, mildew will easily occur. If accumulated too long, the nitrates contained in the grass will form highly toxic nitrites. If the pigs eat it, they will be poisoned or suffocate due to severe hypoxia. death.
Fifth, strengthen the epidemic prevention
According to the epidemiological characteristics of infectious diseases, it is easy to have large-scale epidemics in the fall. However, because the temperature is variable, it is easy to induce the disease of pigs. Therefore, epidemic prevention must still be done in accordance with the epidemic prevention regulations, with emphasis on the prevention of swine plague, swine fever, and swine erysipelas. , swine pneumonia, swine flu, these five kinds of infectious diseases, but also pay attention to the prevention of Eperythrozoonosis, swine cold, swine streptococcus disease, infectious gastroenteritis and other diseases. Note: Before the vaccine is done, it is best to use a liver-protective and kidney-protective drug --- pig incompetence for 5-7 days, eliminating "bottom color disease" to ensure immunity.
Sixth, strengthen health and disinfection
Pig farmers must also step up the cleaning and disinfection of pig houses. They usually clean the house once a day and disinfect it once every 3 days to avoid the breeding of pathogens.
