Soybean meal is considered one of the main ingredients for animal nutrition, due to the lower production capacity in some countries, the imported soybean meal is commonly used as a protein component in poultry diets. During the last years, feed producers have been improving the technical potential of the thermal process of the domestic soybean seeds. As a result, there are different by-products that could be formulated in animal nutrition such as:

All these products have different nutrient contents and thus can be fed to different species of animals.
The use of soybean products is limited by the presence of anti-nutrients, mainly inhibitors of proteolytic enzymes such as trypsin and chymotrypsin.
For that reason, a recent study “aimed to determine the overall effect of replacing soybean meal completely with soybean expeller cake or extruded full-fat soybean in feed rations for broiler chickens on their carcass composition and meat quality”.
The variables evaluated included:
Materials and methods

Soybean meal (SBM)
Soybean expeller cake (SEC)
Extruded full-fat soybean (EFS)
