At about 16 o'clock on July 5, a pipe surge occurred in the first-line embankment of Tuanzhou Dongting Lake in Huarong County, Yueyang City, Hunan Province. By 23 o'clock, the width of the embankment had been extended to about 150 meters.
The 150-meter-wide embankment is like a giant beast opening its bloody mouth, devouring the solidity of the embankment and the last glimmer of hope for people's sense of security. About 5,000 people in 6 villages and 1 community in the vicinity were evacuated, and their homes and fields turned into an ocean in an instant.
And Huarong County, which is at the core of the disaster area, is the new national pig transfer county in 2022. What's more worrying is that not only Huarong County, but also its surrounding Nanxian County, Jinshi City, Hanshou County, Yuanjiang City, etc. are all large counties in the country where pigs are transferred, and they all belong to the Dongting Lake District.
This means that the danger of the embankment burst in Huarong County may have a significant impact on more than 1,000 pig farms in the entire Dongting Lake area.
As we all know, Hunan Province is a large pig province in the country, and it is also a large province for pig transfer, data shows that in 2022, Hunan Province will have 65 large counties for pig transfer, including Yueyang County, Xiangyin County, Miluo County, Hanshou County, Jinshi City, Yuanjiang County, Nan County, etc.
However, everything was pale under the natural disaster.
Although pig farmers have just come out of the deep loss market in the past two years, and although the bonus period is only one month, pig farmers have not even gotten a respite...... The disaster may have brought some pig farmers back to their pre-liberation period overnight, and even took away their last capital. Regretful, helpless......
However, the impact of this levee burst and the flood-stricken area on the pig industry may be much more than that!
In recent days, heavy rainfall has continued in most parts of Hunan Province, with landslides, road blockages and rainwater backfilling in many places, in addition to direct economic losses, the more serious impact may lie in environmental pollution and the spread of the epidemic.
Under the flood situation, the comprehensive utilization of pig manure in Dongting Lake area is worth paying attention to
Pushing back the time to 10 years ago, the disorderly expansion of pig farms in the Dongting Lake area at that time caused heavy environmental pressure on the Dongting Lake area, and even in a large pig breeding town in Yueyang City at that time, residents dug wells, and dozens of meters were pig urine.
In the face of such a serious problem of breeding pollution, as early as the "13th Five-Year Plan" period, the Ministry of Agriculture and Rural Affairs pointed out that it is necessary to do a solid job in the comprehensive utilization of pig manure, focusing on the Dongting Lake area, and accelerating the transformation and upgrading of pig breeding in the southern water network area. It has been planned that by 2020, the pig breeding structure of 33 counties (cities) in Dongting Lake District will be further adjusted and optimized, the proportion of large-scale pig breeding will reach more than 70%, the proportion of large-scale farms supporting manure treatment and utilization facilities will reach 85%, the manure in intensive breeding areas will be centrally treated, and the comprehensive utilization and harmless treatment rate of pig breeding waste will be gradually improved, and a new pattern of pig breeding with high output, product safety, resource conservation and environmental friendliness will be gradually established.
The information shows that in 2022, the comprehensive utilization rate of livestock and poultry manure in Hunan Province will reach more than 83%. In recent years, the comprehensive utilization rate of livestock and poultry manure in Hunan Province has been significantly improved, but in the face of such a strong rainstorm, these supporting facilities do not know whether they can withstand the test, and I don't know how much manure will rush downstream with rain and floods, bringing the risk of epidemic transmission again. It is important to know that a large part of the transmission of African swine fever is through feces and urine.
In the face of heavy rain and flooding, experts recommend:
During the period of continuous rainfall, ensure the supply of production materials, strengthen infrastructure maintenance and feeding management, and timely do a good job in breeding manure treatment and disease prevention and control and other recommended measures. In particular, it is necessary to do a good job in the inspection and reinforcement of the farm area and flood control and drainage work, and the pig farm should be widened and deepened to ensure that the surrounding and domestic water is discharged in time; Inspect the drainage system in the venue, clean up debris, place water baffles and sandbags in low-lying areas of the venue, and prepare for drainage and drainage; Timely treatment of flooded, rainy, blistered, moldy and deteriorated forage feed, and replace fresh and high-quality raw materials to improve the disease resistance of pigs.
