Warming temperatures in spring is a good time for pigs. However, the fluctuant weather in spring has caused a large number of germs to multiply. Failure to adopt effective management measures and thorough sterilization may cause various pig diseases, which is not conducive to the economic benefits of pig farmers. Therefore, it is of great significance to strengthen the analysis of the key technical points for spring pig raising.
One, increase the environmental control of spring pighouse
Strengthen the emphasis on the disinfection of pig houses, ensure that the pig house maintains a dry, warm and ventilated environment, pay attention to pig house hygiene, and cut off the conditions for the survival of germs. These are the basic steps to improve the benefits of pig raising in spring. Because pigs like a warm and dry living environment, especially their own body temperature regulation function is not perfect, the surface deposition of fat is less, the ability to resist cold is relatively weak, easy to get sick; coupled with the spring weather changes, a large temperature difference between day and night Therefore, it is necessary to keep the pig house warm and dry, ensure fresh air, and create an excellent environment for the pig's growth and development. Especially in the northern regions, sows are required to warm the real estate to ensure that the piglet is fully active and full. Therefore, it is advisable to spray nursing care once every two weeks in each pig house, effectively absorb moisture and dehumidify, keep the pens dry, plant beneficial bacteria, and suppress the proliferation of pathogenic microorganisms in pig houses.
Second, implement fine management and feeding
The feeding and management of finishing pigs and breeding pigs in spring should follow the principle of “timed and quantitative†feeding. For piglets, due to the lack of innate immunity, poor digestive function, coupled with frequent changes in temperature in spring, if there is slight negligence in feeding and management, it may cause disease. Therefore, besides doing a good job of disinfection and improving the environment, fine-grained feeding and management should be implemented to ensure the cleanliness of the sow's udder and help the piglets to successfully go through the three aspects of opening food, feeding, and savoring food, and completing the new year's customs and feeding materials. And weaning off, especially to strengthen the nursing of weaned piglets. For different rearing stages, attention should be paid to feeding full-priced compound feeds, maintaining adequate drinking water, lighting, and taking appropriate exercise to promote the healthy growth of piglets.
Third, focus on scientific nutrition supply
Spring is the peak period of various infectious diseases, and pig breeding should be done well. If an outbreak occurs, it should be strictly blocked and thoroughly disinfected, and methods of injection prevention should be adopted. The dead pigs should be properly disposed of in accordance with relevant requirements to avoid inflows into the market. If the outbreak of swine disease is found in the surrounding areas, in addition to the basic disinfection work, foreign personnel should also be prevented from entering the pig house. In addition, the nutritional level has a direct impact on the health status of the pigs. Through high-level and adequate nutrition supply, the basic nutritional needs of the piglet growth can be met, and the immunity of the pig against diseases can be improved. In combination with the different growth stages of the pigs, the full-price diet is planned to follow, and nutrition standards are followed. In combination with the actual weight of the pigs and the feed intake, the diet formula is optimized. It is recommended that sows 1 and Oderman A be added to the sow's diet to effectively increase the body resistance of the sow and increase the reproductive performance of the sow; 2% of the weaned pig diet should be supplemented with Aberdeen No. 1 + 0.25% Oder. Mann A, effective in alleviating weaning stress, reducing diarrhea, and improving body immunity; adding 2% Huzikang No. 2 + 0.25% Oderman A to the diet of nursery pigs, effectively reducing the nutritional diarrhea of ​​nursery pigs, and increasing the growth rate. Improve the body's resistance to disease; Adding 0.5% macrolide + 0.25% Oldman A to finishing pig diets effectively increases the growth rate of pigs, improves feed conversion, and reduces feed-to-meat ratio.
Fourth, do a good job of prevention of common swine disease
The spring is the multiple period of swine disease. The main analysis of common swine diseases is as follows:
4.1 Porcine diarrhea
Diarrhea is one of the common symptoms of spring swine disease, including dysentery, colibacillosis, and diarrhea in weaned piglets. Mainly due to many reasons such as feed, environment or epidemic prevention. After diarrhea occurs in pigs, it is necessary to accurately identify the remedy and supplement enough body fluids to avoid dehydration or secondary infection. While improving the treatment effect, we must also prevent the entire group of pigs: we can add 0.5% Odemann A to the whole diet to improve the body's resistance to diseases, purify pathogens in the body, and avoid widespread epidemics. In addition, it is also very important to maintain the warmth and heat preservation of the pig house, maintain the suitable temperature and humidity in the pig house, avoid sudden temperature changes, and reduce the stress response after the pig’s diarrhea.
5.2 Swine flu
Swine flu is mainly from influenza virus. Its incubation period is about 3-7 days, and the duration is 7 days. The symptoms of swine flu are mainly loss of appetite, apathy, dyspnea, fever, cough, etc. It may also be accompanied by bronchitis, pneumonia, etc. complication. The best way to prevent swine flu is to ensure environmental hygiene and cleanliness. At the same time, add 0.5% Odemann A to the diet of swine flu adjuvant adjuvant vaccine to improve the body's resistance to diseases and purify pathogens in the body.
5.3 Porcine edema
The incidence of the disease in the spring is extremely high, mainly due to pathogenic E. coli. Pig enterotoxaemia occurs after weaning of piglets. When weaned pigs were weaned, due to feed changes and environmental changes, caused by a variety of incompatibility, the symptoms are manifested as apathetic, edema in head, neck, eyelid, anus and other parts, individual systemic edema, there is more obvious pressure Traces of limb numbness occur later in the disease and the duration of the disease is shorter. The prevention of the disease can be optimized to adjust the amount of feed, and it can also be fed with green feed, combined with detoxification, diuresis, antibacterial and other treatment methods.
It can be seen from the above that spring is both a good time for raising pigs and a high incidence of swine diseases. Only by strengthening the importance of key pig-breeding technologies, improving traditional pig-raising concepts, strengthening pig management measures, and doing a good job of pig house disinfection, fine feeding, and nutrient supply, can the pig's immunity be enhanced and the aquaculture efficiency goals can be achieved.
