Soy Swine Nutrition Research Program
The Soy/Swine Nutrition Research program is a managed research
program that has had over a dozen researchers at various institutions
working together to discover ways to optimize the use of soybean
products in swine diets. Now working with a complementary program
funded by the Illinois Council on Food and Agricultural Research,
soybean compositional data has begun to be made available from
the website SAND,
Soy in Animal Nutrition Databases.
While soybean meal is the supplemental protein of choice in swine diets around
the world today, it is far from being a perfect product. Less
than 50% of soybean meal is protein, with the remainder made up
of water, minerals, and a myriad of organic compounds. While nutrient
content, digestibility, and some growth inhibitors have been characterized,
there are large gaps in existing knowledge that may be the key
to improving the fundamental nature of soybean meal products in
Soybean meal is a superior swine diet component because the profile of amino
acids found in its proteins offsets the deficiencies in cereal
grains more completely than any other commercial oilseed meal.
Yet, there are a number of factors with the potential to erode
the competitive position of soybean as an ingredient in swine
diets. For example, the explosive growth in the industrial capacity
to produce key amino acids makes it easier to supplement other
oilseed meals with key amino acid. This can substantially improve
their nutritional worth in comparison to soybean meal.
The Soy/Swine Nutrition Research program has begun to fill in the knowledge
gaps and address some of the concerns. The program brought together
top research and industry representatives from eleven institutions
in several countries to pursue five interrelated lines of investigation.
Together, this group has comprehensively investigated the nutritional
optimization of soybean meal in swine diets.
