Soybean Meal Use – Large Mouth Bass

March 2019

Researchers at Kentucky State University evaluated cost-effective alternative plant-proteins in feeds for large mount bass.  A feeding experiment compared various dietary supplements (glycine, prebiotic product and nucleotide mix) in a low-fish meal (4%); soybean meal (50%) based diets.  Twenty largemouth bass were fed twice daily for 10 weeks per treatment. Results indicated that the supplementation of glycine to a low-fish meal-high soybean meal diet slightly improved growth and feed efficiency of the largemouth bass.  More importantly, fish meal can be reduced from 44% to 4% with soybean meal supplemental glycine with essential equal fish performance. The author indicated that the feed cost savings using soybean meal should provide for higher profit margins for largemouth bass producers.
