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.

这项研究旨在分析虾饲料中无腺棉籽粉（GCSM）的挤压加工潜力。挤出了五种不同的饲料，它们具有不同的鱼油浓度和恒定的GCSM含量。挤出温度，螺杆速度和水分含量是变化的。带有GCSM的最佳挤出物的粗蛋白含量为50.5％，高于商品虾饲料。GCSM的矿物分析表明，除铁之外，所有矿物均在作者提出的限制内：铁为0.13，而铁为0.6。GCSM是必需脂肪酸的极佳来源，可以满足虾对亚油酸和亚麻酸以及高度不饱和脂肪酸的饮食要求。
