Brief Project Summary:

The study evaluated various inclusion rates of a soy variety V12 soybean meal that is low in trypsin inhibitors and oligosaccharides to investigate the effects of utilizing soybean meal in shrimp growth. Growth performance of the shrimp was not compromised. This means soybean meal is an acceptable alternative to fishmeal, which is commercially and environmentally unsustainable. After the study, water quality was adequate for shrimp growth. Despite soybean meal having lower levels of methionine and lysine, two growth-limiting essential amino acids in shrimp, the findings were not significant. Pacific shrimp did not improve in growth.

Key Audience:
Aquaculture nutritionists, aquaculture feed producers, shrimp producers

Information And Results
Project Deliverables

1) A soybean variety with enhanced seed compositions that can increase SBM inclusion rate in shrimp diets.
V12-4590 will be released in March 2019 for either commercial production or germplam with enhanced traits. We are looking for seed companies to license this value added variety.

2) Aquaculture producers’ awareness of the benefits of using VSMB
Because we just completed all the expts, we haven’t had a chance to present the benefits of VSMB to aquaculture producers. We will make effort to do it in Mid-Atlantic region (pls see below).

3) Publication(s) and presentation(s)
Because we just completed all the expts, we didn’t present the study in 2018. However, Zhang will present the results at annual Virginia Crop Improvement Association conference on 2/21/19 and annual Virginia Soybean Board meeting on 3/7/19. Kuhn will also present the results at regional aquaculture meetings in 2019. A manuscript is underwritten now, and will be submitted to J of Aquaculture Nutrition by March, 2019.

The present study evaluated various inclusion rates of SBM from the novel V12 soy variety to replace fishmeal as an aquafeed source of protein. To our knowledge, this is the first study investigating the effects of utilizing SBM from a soy variety being low in trypsin inhibitors and oligosaccharides in shrimp growth. Fishmeal substitution with V12 SBM, up to 45%, shows potential as an alternative vegetable protein source, without compromising the growth performance of the shrimp. Given the high sustainability of soy, the use of SBM from the V12 soy variety can help decrease the pressure on fishmeal usage for aquafeeds. Further investigation is needed to confirm possible animal physiology benefits of the use in the diet, for example trypsin activity in the digestive tract.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
