The weather in autumn is changeable, and pig farms should strengthen management. The author made several suggestions for the management of autumn farms for reference.
1. It is not suitable to construct and reform pig farms. In the fall, the temperature is reduced, the time and intensity of sunlight exposure are greatly reduced, and the chance of pathogen transmission is greatly increased. If construction is continued, construction workers will bring sickness into the field and cause more possibility of infection; therefore, construction on site should be stopped as soon as possible to prevent infection. The spread of sexual diseases.
2. Make preparations for changing weather in autumn. Autumn is the season where climate change is the largest and most frequent. The damage to pig farms is also caused by improper environmental factors such as temperature, humidity, and air quality. If measures are taken to effectively respond to climate change, the losses will be minimized. First of all, the temperature is the most important. Warming facilities should be prepared before any temperature changes, such as the maintenance of boilers, the preparation of coal, the sealing of windows, and the availability of plastic sheets.
3. Adjust the breeding plan to prevent the management difficulties caused by the over-concentration of mating. The problem of sows not estrus and low fertility rates due to high temperatures and disease infections is coming to an end. After autumn, there will be a large number of sows to be bred and obvious estrus will occur. If indiscriminate breeding, it will result in farrowing during the Spring Festival. The emergence of. During the Spring Festival, the frequent movement of people, coupled with the high workload of the farrowing peak, led to the emergence of common disease epidemics and high mortality rates. The multi-edged pigs did not bring in more slaughter results. Therefore, breeding in the autumn should not be excessive, but should be carried out in accordance with the normal breeding program to avoid undue losses. This requires planned pig farms to be implemented as planned. Unplanned farms will develop a mating plan as soon as possible and implement it strictly.
4. Develop a comprehensive plan to deal with autumn and winter diseases. Respiratory diseases in autumn and winter, No. 5 disease in winter, infectious gastroenteritis and epidemic diarrhea have all caused considerable losses to many pig farms. These need to be prepared in advance.
The prevention of respiratory diseases mainly considers improving the environment and necessary drug prevention. How to make the pig herd transition from a large free-window ventilation to a faintly-ventilated ventilation needs to pay attention to the changes of climate at every moment and adjust the air volume through the window switches in time. It is important to prepare related facilities in advance.
Prevention of the fifth disease. Most of the pigs with the fifth disease are caused by the lack of antibodies. Therefore, after the autumn, the dose of the vaccine should be increased, the number of injections should be increased, and the use of highly effective vaccines is necessary.
Infectious gastroenteritis and epidemic diarrhea are common infectious diseases in winter. Due to the difficulty of vaccine injection, especially the medium and large pigs, many pig farms have not been able to vaccinate large pigs, but the pigs that are affected are often large pigs. What needs to be emphasized here is that every big pig grows up from piglets. If the piglets are vaccinated two months in advance, the antibodies in the body can still resist the threat of pathogens when they grow up, which will greatly reduce the risk of disease. .
5. Do a good job of the lack of emergency measures before and after the Mid-Autumn Festival. The Mid-Autumn Festival is the time for the farmers to harvest in the north. The pig farm will face the problems caused by lack of personnel. If the treatment is not good, the root cause of autumn and winter will be left during this period. It is necessary to consider whether or not to arrange the personnel arrangements before and after the Mid-Autumn Festival one month in advance or even earlier.
6. Ready to adjust feed formulation at any time. In the autumn, when new corn is put on the market and new and old corns are blended and used, due to the difference in the nutrient composition of the old and new corn, it will lead to instability of feed nutrition, which will lead to instability in the production of pigs. The impurities in the new corn are screened out, and corn with more moisture content is converted into standard maize with normal moisture content. In combination with the increase in energy demand of pigs when the temperature is lowered, the formulation is constantly adjusted to ensure the nutrient supply of the feed and ensure the nutritional needs of the pig. Dynamic balance.
There are still many problems in the ever-changing pig farms, and each pig farmer needs to be discovered and resolved in time.
