What was accomplished under these goals?
Data for the comparison of digestiiblity of amino acids in soybean meal collected throughout the United States were published in a peer-reviewed publication. Data for a second digestibility experiment that compared ileal amino acid digestibility in soybeanmealproduced in China, India, Brazil, Argentina, or the U.S. were summarized and published in a peer-reviewed publication. Data for an experiment to determine the nutritional value of soy protein concentrate produced to provide different particle sizes were also published in a peer-reviewed mansucript. All activities related to this Hatch Project were completed.

What do you plan to do during the next reporting period to accomplish the goals?We plan topublish two more manuscripts in peer-reviewed journals from this project.
Impacts
What was accomplished under these goals?
The digestibility of amino acids and phosphorus was determined in 23 sources of soybean meal that were collected from throughout the soybean growing area in the U.S. The main results indicated that soybean meal produced in the U.S. is very consistent in nutritional value regardless of the area from which the soybeans were sourced. This information will help feed formualtors and swine integrators in the formulation of consistent diets for pigs. Digestiiblity of AA and energy in soy protein concentrate was also determined and the animal work from that project is completed. The animal work for the above three goals has been completed. Manuscripts from these objectives have been published or will be published in 2017.

What opportunities for training and professional development has the project provided?A graduate student completed her PhD on this project. How have the results been disseminated to communities of interest?Results were disseminated through an abstract and presentation at the National Animal Science Meeting in Orlando, FL (July, 2015) and through a peer-reviewed publication in the Journal of Animal Sciences. What do you plan to do during the next reporting period to accomplish the goals?We intend to complete Objectives 2 and 3 in 2016.
Impacts
What was accomplished under these goals?
Major progress was made towards Objectives 2 and 3.Objective 1 on determining the energy value of soybean meals from different areas of the United States was completed. A manuscript was published in a scientific journal based on this research. The major conclusion from this work was that the energy value of soybean meal produced in the United States is greater than what has previously been concluded. This will increase the economic value of soybean meal from the United States. The animal work involved in Objectives 2 and 3 was completed and mansucripts to communicate the results from these experiments will be published in 2016.

What opportunities for training and professional development has the project provided? A graduate student is being trained in animal nutrition and a post doctoral research fellow is being trained in nutrition andoverall project management. How have the results been disseminated to communities of interest? Results have been published in a conference proceeding from the American Society of Animal Science and in a podcast that is available on the Stein Monogastric Nutrition Research website at http://nutrition.ansci.illinois.edu/podcast/prediction-concentrations-digestible-metabolizable-and-net-energy-soybean-meal-throughout-un. Results were also published in a research report in the March issue of the Stein Nutrition Newsletter (http://us5.campaign-archive1.com/?u=95ed6241b9dab81c9e3425d5d&id=3fc7640cfb). What do you plan to do during the next reporting period to accomplish the goals? We will complete Objective 3 of the project plan. Animal work towards this objective was recently initiated and will be completed before the end of the current project period.
Impacts
What was accomplished under these goals?
Objective one has been completed and a final report prepared. During the project year, all work towards objective 2 was also completed. The 22 sources of SBM that were used in Objective 2 were organized the same way as outlined for Objective 1 and diets containing each source of SBM as the only AA containing ingredient were formulated and fed to ileal cannulated pigs. Digesta were collected according to standard operating procedures and digestibility of AA in all sources were calculated. Results indicated that for most AA, no differences among sources were observed and region within the U.S. does not appear to be a major factor in determining the digestibility of AA. Data from the experiment were written into a final report that will be submitted for publication in a peer-reviewed journal. Data will also be presented at the National Animal Science Meeting in 2015 and a podcast presenting the results will be published on our website.

What opportunities for training and professional development has the project provided? Graduate student training How have the results been disseminated to communities of interest? Results have been submitted for preseantation at a scientific meeting. What do you plan to do during the next reporting period to accomplish the goals? We will conduct more research with soybean meal and we will get current results submitted for publication in peer-reviewed journals.
Impacts
What was accomplished under these goals?
An experiment was conducted to determine the apparent total tract digestibility (ATTD) of energy and the concentration of DE, ME, and NE in soybean meal (SBM) fed to growing pigs. Twenty-four growing barrows (initial BW: 26.4 ± 1.8 kg) were used and allotted to a 24 × 8 Youden square design with pigs and period as the 2 blocking criteria. Twenty-two sources of SBM were procured from crushing facilities throughout the Midwest. For analysis, the crushing plant locations were separated into 4 zones: 1) Northern U.S., 2) Eastern U.S., 3) Western U.S., and 4) Illinois. The dietary treatments included a corn-based diet and 23 diets based on a mixture of corn and each source of SBM. The ATTD of GE of SBM of Zones 1 and 2 was greater (P < 0.05) than the ATTD of GE of corn, but not different from the ATTD of GE of Zones 3 and 4. The DE of SBM from Zones 1 and 2 was greater (P < 0.05) than the DE of corn. The DE of SBM from Zones 3 and 4 was not different from the DE of corn or SBM from Zones 1 and 2. The ME of SBM from Zones 1 and 2 was greater (P < 0.05) than the ME of SBM from Zone 3 and corn. The ME of SBM from Zone 4 was not different from the ME of SBM from Zones 1, 2, and 3. Net energy of SBM from Zones 1 and 2 was greater (P < 0.05) than the NE of SBM from Zone 2 and corn. The NE of SBM from zone 4 was greater (P < 0.05) than from corn, but not different from the NE of SBM from the other zones. Overall, DE, ME, and NE concentrations were not affected by the zone within the U.S. where SBM is produced.
