Agricultural colleges and research institutions join Alltech to discuss environmental issues
Industry hot topics such as reducing antibiotic residues in food, effectively using limited resources and reducing pollution discussed
[QINGDAO, China] – Experts from agricultural colleges and research institutions throughout China joined together to discuss agricultural and environmental challenges, including how to reduce waste and making farming operations more sustainable, at a recent Alltech China Research Alliance meeting, held in Qingdao.
Alltech China has built long-term cooperative research relationships with 10 well-known universities, research institutes and leading feed and food enterprises.
“The Alltech China Research Alliance is focused on building toward a green agriculture future in China,” said Dr. Mark Lyons, global vice president and head of Greater China for Alltech. “The roadmap to this future requires practical solutions, which will be developed through advanced scientific research and technology and the powerful partnership of these leading agricultural minds.”
Defa Li, professor at China Agricultural University and academician at the Chinese Academy of Engineering, and Kangsen Mai, professor at Ocean University of China and academician at the Chinese Academy of Engineering, along with more than 30 other professors from agricultural colleges and research institutions, attended and spoke at the meeting, sharing the results of their latest research.
“This meeting of the alliance explored how to reduce antibiotic residues in food, how to effectively use limited resources in the midst of population explosion, and how to reduce water and soil pollution,” said Karl Dawson, vice president and chief scientific officer at Alltech.
A new mycotoxin detection method
The Institute of Agriculture Quality Standards and Testing Technology for Agro-Products of the Chinese Academy of Agricultural Sciences (IQSTAP) has established a method for the simultaneous detection of 21 mycotoxins, or their metabolite residues, in the plasma of animals. These include toxins such as aflatoxin B1. This testing is expected to become the agricultural industry standard for the detection of mycotoxins in China.
Recently, Alltech and IQSTAP published an article entitled “Liquid Chromatography-Tandem Mass Spectrometry for Simultaneous Determination of 21 Kinds of Mycotoxins or Their Metabolites in Animal Plasma.” Dr. Ruiguo Wang of IQSTAP, who introduced the study, says that it established a liquid chromatography-tandem mass spectrometry method that simultaneously detects animal plasma aflatoxin B1 and 21 other kinds of mycotoxins or their metabolite residue.
Existing mycotoxin detection methods have very complex sample treatment operations, and high detection costs make it generally difficult to do a variety of simultaneous determinations of mycotoxins. The QuEChERS method (Quick, Easy, Cheap, Effective, Rugged, Safe) is a fast, sample pre-treatment technology developed for agricultural products. It uses the interaction between adsorbent filler and the impurities in the matrix to adsorb impurities to achieve purification.
In this study, 21 samples of mycotoxins and their metabolites in animal plasma were developed by liquid chromatography-tandem mass spectrometry (ICP-MS) based on the QuEChERS principle. The method is simple, rapid, low-cost and accurate. It can be used for combined mycotoxin animal exposure assessment and mycotoxin toxicokinetic study. Wang said this method has been submitted to the Ministry of Agriculture of the People’s Republic of China for review and is expected to pass as a fungal detector by agriculture industry standards.
Functional ingredients for better pork quality
Another breakthrough came from collaboration between Alltech and Jiangnan University to improve food safety and quality. A Jiangnan University research project showed that the addition of rapeseed selenium in the diet can improve the quality of pork, increasing its water-holding capacity and tenderness. An article published based on Alltech and Jiangnan University’s study confirmed that the additions of flaxseed oil and sesame selenium to the diet can improve pork quality, reducing drip loss by 58–74 percent. The organic selenium diets increased muscular selenium content up to 54 percent. Flaxseed oil and selenium can be used to alter the fatty acid structure of pork, increase omega-3 fatty acids and reduce the proportion of omega-6/omega-3 fatty acids in meat, which can lower the risk of cardiovascular disease in consumers.
Minerals matter: How trace minerals can impact pollution
Improper sewage treatment and greenhouse gas emissions are leading to heavy pollution of water, soil and air, and some small-scale farms have been closed because of this pollution.
“This will require improved feed conversion, which will reduce damage to the environment without affecting the performance of the animal,” said Li.
Inorganic trace minerals in feeds have contributed to this environmental pollution. Due to their low absorption rates, 80–90 percent of inorganic zinc and copper will generally be excreted by the animal, contaminating water and soil.
Organic trace minerals, however, are absorbed more readily. Alltech’s Total Replacement Technology™ is a groundbreaking approach to organic trace mineral nutrition. It features products such as Bioplex®, which includes copper, iron, zinc and manganese, and Sel-Plex®, which includes selenium. Compared to conventional inorganic minerals, these formulations are better absorbed, stored and utilized by the animal and are thus able to meet the higher nutrient needs of modern livestock for rapid growth, maximum reproductive performance and animal health. Additionally, because they are absorbed more readily, less is excreted into the environment.
Some Chinese feed companies are already using Alltech’s Total Replacement Technology. In addition to aiding in animal performance and health, many customers have noted it improves the smell of pig farms.
