On the morning of October 21, the main forum of the 10th Li man China Pig Raising Conference was held in Chongqing International Expo Center. The meeting was presided over by Professor Cao Yongguo of the College of Veterinary Medicine of Jilin University. Professor Liu Aimin of the University of Minnesota, Ms. Meredith McQuaid, Vice President and Director of International Programs at the University of Minnesota, Yin Yulong, Academician of the Chinese Academy of Engineering, Yuan Changding, Secretary General of Chongqing Animal Husbandry Association, and Fan Wei, Chairman and President of ZhaoFenghua Biology of Dabeinong Group, delivered speeches at the conference. The meeting was attended by thousands of people, including leaders from relevant departments, experts from institutions and institutions, heads of associations and enterprises and technical representatives, and the scene was full.
The main forum is live
Professor Liu Aimin delivered a speech
Academician Yin Yulong made a report at the scene
Academician Yin Yulong made a report on the theme of "Solutions for Maximizing the Potential Value of Animal Production" at the main forum. Academician Yin Yulong pointed out that at present, domestic pig breeding is developing towards intensive scale, from the pursuit of quantity to the pursuit of quality, but the production level is still quite different from foreign countries. Feed cost is the biggest cost of breeding, he believes that through the establishment of feed raw materials rapid assessment system, raw material dynamic nutrient content system, animal dynamic nutrition demand system, pork quality rapid evaluation system, breeding benefits maximization dynamic nutrition system, to help reduce costs and increase efficiency and pork products to increase premium, to enhance pig breeding efficiency, reduce feed costs, alleviate the shortage of feed protein resources has important value. Going forward, aisle technology can help achieve precision feeding closed-loop, thereby improving efficiency.
Video report by Professor Montes Torremore
Professor Montes Toremore of the University of Minnesota said in "Air Filtration in Pig Farms: Fundamentals and Advantages" that pig blue-ear viruses, influenza viruses, mycoplasma, and epidemic diarrhea viruses can be transmitted by air. Air filtration is an important part of biosecurity, especially in places where pig farming densities are medium and relatively high. Studies have shown that after the installation of air filtration systems, the outbreak of pig blue ear disease virus on farms can be reduced by 80%, and the annual net income per sow can increase by $38. After installing the filtration system, it is necessary to maintain and inspect it regularly, paying special attention to the problem of air leakage. With the passage of time, the efficiency of electrostatic filters will become lower and lower, and mechanical filters will perform better in the later stages.
Professor Zeng Zhenling gave an on-site report
In the theme report of "Under the policy of reducing resistance and limiting resistance, antibacterial drugs should be prospected in the pig industry", Professor Zeng Zhenling of South China Agricultural University mentioned that in 2020, there are 1655 veterinary drug manufacturers in the country, including 1514 chemical companies and 119 biological products enterprises, and mainly small and medium-sized scales. At present, new viruses continue to be discovered, and the pace of drug development has slowed down, and bacterial drug resistance has become one of the threats to human health. Irrational use of antibiotics will make the industry eventually "drug-free". The implementation of the policy of reducing resistance and prohibition has significantly reduced the antibacterial drugs required for the production of one kilogram of meat, but it has also brought about the challenge of reducing the survival rate of pigs due to viral infections that cannot be treated in time. To achieve a reduction in the use of antibiotics, vaccine immunization is key, biosecurity is the core, and good feeding management is the foundation. Remember not to demonize, not to abuse antibacterial drugs, to use antibacterial drugs reasonably.
Simon Quilty Audio Report
In his report Global Agricultural Trends, pork trading expert Simon Quilty analyzes several potential factors that will affect the future development of global agriculture. He believes that extreme weather such as drought and precipitation caused by La Niña around the world may reduce the production of agricultural products, which in turn will affect the supply of feed raw materials. Due to the COVID-19 lockdown, labor mobility has decreased, and the cost of employment caused by labor shortages has risen. The number of containers is decreasing dramatically, and the cost of transporting bulk raw materials is rising sharply and taking longer. The African swine fever outbreak across many countries will have a lasting impact on pig production and supply. However, consumer confidence continues to be boosted due to rising COVID-19 vaccination rates, which is a potential positive. He expects global meat prices to show a strong trend in the next two years.
At present, the domestic pig market is sluggish, but pig farmers should also continue to do a good job in basic production management such as feed nutrition and disease prevention and control. The four experts of the main wheel altar of the conference made reports and sharing from animal nutrition, disease prevention and control, global industry trends, etc., which has good guiding significance for pig farmers to cultivate internal skills and improve their ability to cross the cycle.
It is understood that the number of participants in this year's Li man conference reached 11,036. From October 20th to 22nd, Li Man will share more than 100 thematic reports in three days, covering pig case studies, Sino-US pig production management sharing, application of pig production data, application of antibiotics and food safety, molecular biology diagnosis, monitoring and prevention of diseases.
