USSEC: US soy's value demonstrated through greater consistency
When it comes to soybean quality, the US soy industry wants to be sure that its customers are armed with the right information, US Soybean Export Council (USSEC) said.
The "US Soy Family", which includes the USSEC, American Soybean Association (ASA), and United Soybean Board (USB), promotes numerous studies around soy quality, providing international customers with the necessary information to make the right soy choice.
Since 1986, USSEC partners with the University of Minnesota's Department of Agronomy & Plant Genetics to gather samples from soybean producers across the US' growing regions to analyse them for protein, oil, and amino acid concentration, yielding scientific data that verifies the exceptional composition and high nutritional value of US soy.
In 2017, sample kits were mailed to 6,688 producers selected based on total land devoted to soybean production in each state, so that response distribution would closely match that of soybean production. By early December, 1,837 samples were received, which were analysed for protein, oil, and amino acid concentration.
Preliminary survey results show that, across US growing areas, protein concentrations were unusually consistent across the US in 2017, although slightly lower overall than 2016 levels and historical averages. However, oil concentrations in 2017 were nearly equal to 2016 levels and were higher than historical averages. Additionally, essential amino acid results varied very little by state and region and the US average of essential amino acids was slightly higher than last year.
The quality study also found an increase in protein concentrations in some northern states. For example, Minnesota and South Dakota soybeans had higher protein in 2017 than 2016, with South Dakota increasing protein by nearly one percentage point.
Because protein levels were similar across all US growing areas, this indicates that the US will be exporting soybeans with a more consistent nutritional bundle from all port locations.
Recent studies comparing soybeans of different origins continue to reinforce the understanding that US soy provides the nutritional bundle needed to optimise animal nutrition and profitability. The full value of US soybean products is found when buyers consider total metabolisable energy, batch-to-batch consistency, essential amino acid profile and digestibility.
Dr. Gonzalo G. Mateos, professor of animal science at the University of Madrid, conducted research study on the nutritive value and energy quality of soybean meal for pigs and poultry. His team compiled data, gathered over eight consecutive years, to map out the energy and protein levels of samples of the world's largest exporters of soybean meal: the US, Brazil and Argentina. In his peer-reviewed and published study, Mateos concluded that composition and quality of protein is the best indicator of nutrition. He said that US soybean meal is the world's top and most convenient of the world's protein meals' supply.
Dr. Hans H. Stein, professor of animal nutrition at the University of Illinois, analysed digestible, metabolisable energy in swine by analysing soybean meal from China, Argentina, Brazil, and the US as well as four sources from India. Dr. Stein's peer-reviewed and published study showed that US soybean meal had more digestible amino acids than that of other origins and that soybean meal from the US has greater digestibility and less variability in composition and digestibility.
This global research continues to demonstrate that soybeans and soy products can vary widely depending on their origin. Year after year, US soy can be counted on by nutritionists and managers to consistently maximise animal performance and reduce production costs, USSEC concluded.
