Will there be an outbreak of pig disease after heavy rains in the south in June? Will pork prices be affected in the second half of the year?

The continuous rainfall in June has brought a lot of casualties and property losses to our country, so will there be an epidemic of pig disease after the rainstorm in the south in June? Will pork prices be affected in the second half of the year? Let's take a look at it with the editor.

The harm of rainstorm

Torrential rain and the flood caused by it is one of the main natural disasters in China, which occurs more frequently in recent decades, and flood disasters with large damage area, wide regional distribution and serious economic losses occur almost every year. However, attention should also be paid to the prevention and control of parasitic diseases after the disaster. After the rainstorm in summer, there is an epidemic and high incidence period of various animal diseases, so immediate measures should be taken to disinfect the source and treat the drowned animals innocuously.

Due to the overflow of the dung tank after rain, the pollutants flow with the water, and the enclosures, fences and feeding utensils that have been submerged by the water are seriously polluted. At the same time, the pathogenic bacteria in the soil are washed out by the flood, causing large area pollution of the environment and causing animal diseases. For this reason, it is necessary to thoroughly clean and disinfect the enclosure, fence, feeding utensils and the surrounding environment. Disinfect with 10%-20% lime water, plant ash water, 2%-3% fiery alkali solution, 2%-5% peracetic acid solution and other disinfectants, and do a good job of killing rats at the same time. Do not eat drowned livestock and poultry carcasses, let alone litter them at random. They should be buried or incinerated under the guidance of the local animal health supervision department. In addition, after the flood, animal health and epidemic prevention departments should carry out immunization in an organized and planned manner to improve the immune density of animal groups.

Will there be an epidemic of pig disease in heavy rain?

In recent years, viral diseases in large-scale pig farms tend to ease and bacterial diseases are on the rise. There are many multi-pathogenic swine diseases, such as classical swine fever, pseudorabies, parvovirus disease, Japanese encephalitis and other viral reproductive disorders, secondary or mixed infection of Haemophilus parasuis, streptococcosis, pasteurellosis, colibacillosis and other diseases; and whether it is bacterial or viral. The clinical symptoms of diseased pigs are very similar, mainly reflected in the symptoms of respiratory diseases, which bring great difficulties to the diagnosis, treatment, prevention and control of the disease. It is understood that respiratory syndrome is caused by the interaction of viruses, bacteria, environmental stress, mycotoxins and low immunity in pigs. But after heavy rain, it is easy to breed all kinds of germs.

Experts remind farmers to strengthen feeding management and improve the disease resistance of livestock and poultry. Pay attention to ventilation in the enclosure, control the temperature and humidity in the house, clean the food trough and drinking fountain in time, and remove feces and bedding materials in the house. Pigs, cattle and sheep are kept in captivity to prevent livestock from getting infected by eating forage grass or water contaminated by pathogens. Livestock and poultry breeding should focus on the cleaning of drinking water and feed, feed more high-quality forage feed, not mildew forage feed, on the basis of ensuring the supply of clean food, add vitamins and other additives to improve the immunity of livestock and poultry in feed or drinking water to enhance the disease resistance of livestock and poultry.

Will pork prices be affected in the second half of the year?

According to a report on July 4, pig prices on the 4th: the national average price of lean pigs is 6.98 yuan per jin, which is the same as that of No. 3 and 2.43 yuan lower than that of 9.41 yuan per jin in the same period last year. Average price by province: Heilongjiang 6.8, Jilin 7.0, Liaoning 6.9, Hebei 7.0, Tianjin 6.9, Beijing 6.9, Shanxi 6.9, Shandong 7.2, Anhui 7.0, Jiangsu 7.0, Fujian 7.4, Guangdong 7.0, Henan 7.0, Jiangxi 7.0, Hubei 6.9, Hunan 6.8, Shaanxi 6.6, Sichuan 6.9, Yunnan 7.0. The average price of lean pigs in the country is stable, and the fluctuation of pig prices in various provinces is also relatively stable. Pig prices in the north are slightly adjusted, and the trend is weak in many places. Among them, pig prices in Heilongjiang, Tianjin, Beijing and Shaanxi have dropped by about 0.1 yuan / kg, while pig prices in Liaoning and Shandong have risen by 0.1 yuan / kg, while pig prices in other areas have remained stable. Pig prices in the south are mainly stable, while pig prices in southwest, Anhui, Fujian and Hubei are stable, Jiangsu and Jiangxi slightly increased by 0.1 yuan / kg, and Hunan pig prices fell by 0.4 yuan / kg. Today, the average price of lean pigs is the highest in Fujian, with an average price of 14.8 yuan / kg, and the lowest in Shaanxi, with an average price of 13.74 yuan / kg.

Domestic pig prices continue to maintain the trend of small shock adjustment, and the game between supply and demand in the market is fierce. on the one hand, the current consumption is in the off-season of summer demand, and the big pigs that pressed the fence in the early stage have not been fully digested, so it is not too difficult for slaughtering enterprises to collect pigs. as a result, slaughtering enterprises are willing to reduce prices. On the other hand, farmers have a strong expectation of a rise in pig prices in July, and there is a feeling of holding down the fence equivalent to selling. at the same time, the recent rainstorm in the south has affected road transportation, hindered the movement of pigs, and reduced the supply of pigs in local markets, which has contributed to the rise in pig prices in some areas. In the short term, the fierce game between market supply and demand will continue, it is recommended that farmers should re-hurdle, do not overpress the hurdle. At the same time, we need to remind everyone that it is necessary to guard against the occurrence of swine epidemic disease caused by the high temperature after the rainstorm.
