Abstract: Due to the rapid development of livestock, poultry, and aquaculture industries, high-quality feed protein is facing challenges such as increasing demand, rising raw material prices, and inconsistent quality.Finding high-quality alternative proteins has become the key to solving these problems.Cottonseed protein, as a high-quality protein, is widely used in animal feed.It has a protein content of over 40%, is abundant in resources, and has a low price.However, the presence of anti-nutritional factors in cottonseed protein limits its application in production.With the continuous development of cottonseed protein production technology, the removal of anti-nutritional factors from cottonseed protein and further optimization of its nutritional composition through reasonable and effective scientific and technological methods have continuously improved its nutritional value and palatability.Rational utilization of cottonseed protein can not only ensure animal growth performance but also significantly reduce animal feed costs.However, the appropriate addition amount and form of cottonseed protein in different aquaculture animals and growth stages, as well as its impact on animal absorption, metabolism, physiological functions, and mechanisms, have not been clearly studied.The author elucidates the nutritional value, production technology, research status of alternative feed protein sources, and factors influencing the utilization value of cottonseed protein.This provides a reference for the rational use of cottonseed protein and further improvement of its utilization value.
