Soy Products Replace Fish Meal
Many farmers of marine fish are hesitant to use high levels of soybean products in feed due to a fear of reduced feed palatability and digestibility, slower growth, and/or poorer feed conversion compared to traditional...
Methionine Improves Soybean Meal Use in Tilapia Studies
This study evaluated the effects of increasing levels of methionine supplementation on the success of almost total replacement of fish meal with soybean meal (SBM) in diets for hybrid tilapia.  In this study fish were...
Optimum Soybean Meal Levels for Channel Catfish
The objective of this research study was to optimize soybean meal (SBM) levels in diets for pond-raised hybrid catfish (Channel Catfish Ictalurus punctatus×Blue Catfish I. furcatus).   Five 28% protein diets containing 15, 20, 25, 30...
Trypsin Inactivation in Soybeans
Trypsin inhibitors are present in raw soybean meal and in several meal fractions.  At least four inhibitors have been separated on DEAE-cellulose columns.  All of these fractions can be inactivated by steam heating resulting in...
Importance of Properly Processing Soybeans
This research study investigated the effect of varying trypsin inhibitor activity (TIA), heat-degraded lysine concentration and protein solubility in potassium hydroxide (KOH) on broiler performance and pancreas weight.  Two soybean lots were subject to varying...
Improving Crude Protein Digestibility
Improving the utilization of crude protein is subject of many studies because of its economic impact on the animal and poultry industries and detrimental effects of nitrogen excretion to the environment.  Protease supplements have been...
Current Soybean Production and Soybean Meal Use
Three marketing years of soybean production and soybean meal are shown in the following table and chart.   Trends in soybean production and soybean meal use levels are relatively consistent over the past three years, whereas,...
Soybean Meal Use – Walleye Pike
Walleye is a niche-market species that has potential for profitable production in recirculation aquaculture systems (RAS).  Little information is available regarding feeding alternate ingredient, fishmeal-free diets to walleye. This study was conducted to compare the...
Soybean meal Use – Nile Tilapia
Commercial diets used in the aquaculture currently contain marine fishmeal (FM), which has a favorable nutrient profile and palatability, to meet fish nutritional requirements. There is an increasing strain on FM usage in aquafeeds due...
