Additive may lessen effects of soy-induced enteritis in trout

Trimethylamine oxide may reduce nutritional stress and improve overall performance in farmed rainbow trout.

The Soy Aquaculture Alliance (SAA) recently funded a study conducted at the University of Idaho to explore the use of trimethylamine oxide (TMAO) as a feed additive to combat soy-induced enteritis in farmed rainbow trout.

According to SAA, the research also studied if marine fish solubles can be used as a practical means of distributing the additive. The study will continue in the future with different species of fish.

This research concluded that adding TMAO to diets containing soybean meal reduces nutritional stress and may improve overall performance in farmed rainbow trout, which is significant for the domestic aquaculture industry and U.S. soybean farmers alike. Increasing the amount of U.S.-grown soybean meal in fish diets helps manage input consistency concerns while benefiting U.S. soybean farmers, SAA said.

A technical brief about the study has been added to the SAA website.

SAA works to create new opportunities for soybean farmers within the growing domestic aquaculture market. SAA funds programs and research that increase the utilization of U.S. soybeans in the diets of fish and shrimp through affiliations with academic and private researchers and industry leaders.
