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.
The Honourable Bardish Chagger, Leader of the Government in the House of Commons and Minister of Small Business and Tourism, today announced a $1.9 million investment with the University of Waterloo to examine greenhouse gas (GHG) emissions associated with agricultural activities and the potential benefits of alternative land use practices and beneficial management practices (BMPs).
This project with the University of Waterloo is one of 20 new research projects supported by the $27 million Agricultural Greenhouse Gases Program (AGGP), a partnership with universities and conservation groups across Canada. The program supports research into greenhouse gas mitigation practices and technologies that can be adopted on the farm.
According to some early findings from a study by Penn State graduate student Erica Rogers, poultry producers are potentially lowering their impact on the Chesapeake Bay.
Rogers and fellow Penn State graduate student Amy Barkley discussed those initial findings from their two master’s thesis projects with the poultry service technicians attending Monday’s Penn State Poultry Health and Management Seminar at the Lancaster Farm and Home Center.
Her project’s goal is to accurately depict poultry’s contribution to the Chesapeake Bay Total Maximum Daily Load. The Chesapeake Bay “is one of the most studied watersheds in the world,” she said, but the problem with the current model is “they are using outdated information for poultry.”
Rogers built her work around the concept that poultry litter management has changed and farmers have adopted more precise diets for their flocks. READ MORE
Poultry sludge is sometimes turned into fertilizer, but recent trends in industrialized chicken farming have led to an increase in waste mismanagement and negative environmental impacts, according to the United Nations Food and Agriculture Organization.
Droppings can contain nutrients, hormones, antibiotics and heavy metals and can wash into the soil and surface water. To deal with this problem, scientists have been working on ways to convert the waste into fuel. But alone, poultry droppings don’t transform well into biogas, so it’s mixed with plant materials such as switch grass.
Samuel O. Dahunsi, Solomon U. Oranusi and colleagues wanted to see if they could combine the chicken waste with Tithonia diversifolia (Mexican sunflower), which was introduced to Africa as an ornamental plant decades ago and has become a major weed threatening agricultural production on the continent.
The researchers developed a process to pre-treat chicken droppings, and then have anaerobic microbes digest the waste and Mexican sunflowers together. Eight kilograms of poultry waste and sunflowers produced more than 3 kg of biogas — more than enough fuel to drive the reaction and have some leftover for other uses such as powering a generator. Also, the researchers say that the residual solids from the process could be applied as fertilizer or soil conditioner.
The authors acknowledge funding from Landmark University (Nigeria).
February 17, 2016 – New research has shown that tackling antibiotic resistance on only one front is a waste of time because resistant genes are freely crossing environmental.
Analysis of historic soil archives dating back to 1923 has revealed a clear parallel between the appearance of antibiotic resistance in medicine and similar antibiotic resistant genes detected over time in agricultural soils treated with animal manure.
Collected in Denmark – where antibiotics were banned in agriculture from the 1990s for non-therapeutic use – the soil archives provide an 'antibiotic resistance timeline' that reflects resistant genes found in the environment and the evolution of the same types of antibiotic resistance in medicine.
Led by Newcastle University, UK, the study also showed that the repeated use of animal manure and antibiotic substitutes can increase the capacity of soil bacteria to mobilize, or ready themselves, and acquire resistance genes to new antibiotics.
Publishing their findings in the academic journal Scientific Reports, the study's authors say the data highlights the importance of reducing antibiotic use across all sectors if we are to reduce global antibiotic resistance.
"The observed bridge between clinical and agricultural antibiotic resistance means we are not going to solve the resistance problem just by reducing the number of antibiotics we prescribe in our GP clinics,” said lead author David Graham, professor of ecosystems engineering at Newcastle University.
"To reduce the global rise in resistance, we need to reduce use and improve antibiotic stewardship across all sectors. If this is not done, antibiotic resistance from imprudent sectors will cross-contaminate the whole system and we will quickly find ourselves in a situation where our antibiotics are no longer effective."
Antibiotics have been used in medicine since the 1930s, saving millions of lives. Two decades later, they were introduced into agricultural practices and Denmark was among the leaders in employing antibiotics to increase agricultural productivity and animal production.
However, a growing awareness of the antibiotic resistance crisis and continued debate over who and which activities are most responsible led to the EU calling for the use of antibiotics in non-therapeutic settings to be phased out and Denmark led the way.
The Askov Long-Term Experiment station in Denmark was originally set up in 1894 to study the role of animal manure versus inorganic fertilizers on soil fertility.
Analyzing the samples, the team – involving experts from Newcastle University, the University of Strathclyde and Aarhus University – were able to measure the relative abundance of specific β-lactam antibiotic resistant genes, which can confer resistance to a class of antibiotics that are of considerable medical importance.
Prior to 1960, the team found low levels of the genes in both the manured soil and that treated with inorganic fertilizer. However, by the mid 1970s, levels of selected β-lactam genes started to increase in the manured soils, with levels peaking in the mid 1980's. No increase or change was detected in the soil treated with inorganic fertilizer.
"We chose these resistant genes because their appearance and rapid increase in hospitals from 1963 to 1989 is well-documented," explains Professor Graham.
"By comparing the two timelines, we saw the appearance of each specific gene in the soil samples was consistent with the evolution of similar types of resistance in medicine. So the question now is not which came first, clinical or environmental resistance, but what do we do about it?"
Following the ban on non-therapeutic antibiotic use in Danish agriculture, farmers substituted metals for antibiotics, such as copper, and levels of the key β-lactam genes in the manured soils declined rapidly, reaching pre-industrialization levels by 2010.
However, at the same time the team measured a 10-fold rise in Class 1 Integrons. These are gene carrier and exchange molecules – transporters that allow bacteria to readily share genes, including resistance genes.
These findings suggest the application of manure and antibiotic substitutes, such as copper, may be 'priming' the soils, readying them for increased resistance transmission in the future.
"Once antibiotics were banned, operators substituted them with copper which has natural antibiotic properties," explains Professor Graham.
"More research is needed but our findings suggest that by substituting antibiotics for metals such as copper we may have increased the potential for resistance transmission.
"Unless we reduce use and improve stewardship across all sectors – environmental, clinical and agricultural – we don't stand a chance of reducing antibiotic resistance in the future."
May 17, 2013. The Honourable Gary Goodyear, Minister of State (Science and Technology), has announced that seven innovative environmental projects will benefit from more than $32 million in research funding over five years, via the new Climate Change and Atmospheric Research (CCAR) initiative. The funding will support teams composed of university researchers, scientists and partner organizations who will work together to advance the understanding of risks related to climate change.
"Our government is supporting research related to climate change through the creation of the Climate Change and Atmospheric Research initiative," says Goodyear. "We are confident that the knowledge generated through these projects will help improve the quality of life of all Canadians."
Established in 2011, CCAR is administered by the Natural Sciences and Engineering Research Council of Canada (NSERC) and supports climate change and atmospheric research at Canadian post-secondary institutions. Research projects funded through CCAR involve interpreting earth system processes, advancing weather, climate and environmental prediction and understanding recent changes in the Arctic and cold region environments.
