Interpretive Summary: We compared conventional soybean meal (CSBM) and low-oligosaccharide soybean meal (LOSBM) as the main protein source in 28% or 32% protein diets for channel catfish. Regardless of dietary protein levels, fish fed diets containing LOSBM had similar feed consumption, weight gain and feed conversion ratio as those fed diets containing CSBM. Fish fed the 32% protein diets with CSBM or LOSBM had significantly higher feed consumption and weight gain, and lower feed conversion ratio than fish fed the 28% protein diets. Results demonstrate that juvenile channel catfish utilize both CSBM and LOSBM equally well. During fingerling production, channel catfish should be fed a 32% protein feed especially if the diet contains alternative feed ingredients such as corn gluten feed and cottonseed meal.

Technical Abstract: A laboratory study was conducted to compare conventional soybean meal (CSBM) and low-oligosaccharide soybean meal (LOSBM) as the main protein source in 28% or 32% protein diets for channel catfish. Regardless of dietary protein levels, fish fed diets containing LOSBM had similar feed consumption, weight gain and feed conversion ratio as those fed diets containing CSBM. Fish fed the 32% protein diets with CSBM or LOSBM had significantly higher feed consumption and weight gain, and lower feed conversion ratio than fish fed the 28% protein diets. Results from the present study demonstrate that juvenile channel catfish utilize both CSBM and LOSBM equally well. During fingerling production, channel catfish should be fed a 32% protein feed especially if the diet contains alternative feed ingredients such as corn gluten feed and cottonseed meal.
