This study aimed to analyze the extrusion processing potential of glandless cottonseed meal (GCSM) in extruded shrimp feed. Five different diets with different fish oil concentration and constant GCSM content were extruded. Extrusion temperature, screw speed, and moisture content were varied. Optimal extrudates with GCSM had 50.5 % of crude protein, which is higher than commercial shrimp feed. Mineral analyses of GCSM indicate that all minerals are within limits proposed by the authors, except iron: 0.13 compared to 0.6. GCSM is an excellent source of essential fatty acids that might meet the requirements for shrimp diets on linoleic and linolenic acids as well as highly unsaturated fatty acids. Overall results demonstrate that using GCSM as a fishmeal substitute in extruded shrimp feed might be a feasible alternative to reduce feeding costs while showing high protein, minerals, essential fatty acids, and amino acids content. |
