Brief Project Summary:

This project identified a new way to potentially select fish for increased oral tolerance of soybean meal and showed that straightforward qPCR techniques can be used effectively to assess selection potential, such as marker-assisted selection. The project evaluated specific genes in fish selected for growth on a complete plant-based diet over several generations. The principal investigators sought to determine differences in growth and intestinal health when fish were fed a 40% soybean meal diet. Specifically, the liver and distal intestine were examined for gene expression analysis. At 3 months of age, the fish showed superior growth on the diet.

Key Audience:
Aquaculture feed producers, aquaculture nutritionists, rainbow trout producers

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.
